I think that the problem you are encountering is that the USB 3.0 port needs to drop down to USB 2.0 and it is not doing that.There is an issue with these Pro 3 tablets where the USB 3.0 port is 'fixed' at 3.0 and will not drop down. Unknown as to why but Microsoft needs to learn how to configure a motherboard correctly.That port is supposed to be able to drop down to USB 1.1 if needed.There is no fix for that and if you look at the specifications of your USB to RS-232 adapter cable, it will state that it is USB 2.0.If you can find a port replicator and attach it to the USB 3.0 port on the tablet, the replicator can 'correct' that issue since it has a USB controller built into it. My local City Hall encountered a problem similar to this and I found out that the program they where using was designed for Windows 7 which could access COMM ports pretty easy. However, without a driver upgrade in your case for your software to use theCOMM port, you are out of luck because with Windows 10 - it absolutely will not work!Since you are talking about a device with an FAA rating certified back in 1993, that means the software you have is designed for Windows XP. You can definitely forget about getting it to work.There will be nothing wrong with your cable, it will be the driver.

It turns out that your unit is 'dated' and is the problem. However, if you can check with the diagnostic manufacturer, they will most likely have a newer driver you can downloadand use.Coming from an aviation background myself, I know exactly what you are talking about. I would suggest to keep your Toshiba around but keep it off-line as much as possible with Windows XP. It will work almost forever stand-a-lone. Starting with Windows8, the firewall has been redone in a fashion which knocks out connections from the older standards to include Parallel interfaces as well.

Among other improvements, USB 3.0 adds the new transfer rate referred to as SuperSpeed USB (SS) that can transfer data at up to 5 (625 ), which is about 10 times faster than the standard. It is recommended that manufacturers distinguish USB 3.0 connectors from their USB 2.0 counterparts by using blue color for the Standard-A receptacles and plugs, and by the initials SS., released in July 2013, is the successor standard that replaces the USB 3.0 standard.

USB 3.1 preserves the existing SuperSpeed transfer rate, giving it the new label USB 3.1 Gen 1, while defining a new SuperSpeed+ transfer mode, called USB 3.1 Gen 2 which can transfer data at up to 10 Gbit/s over the existing USB-type-A and connectors (1250 MB/s, twice the rate of USB 3.0)., released in September 2017, replaces the USB 3.1 standard. It preserves existing USB 3.1 SuperSpeed and SuperSpeed+ data modes and introduces two new SuperSpeed+ transfer modes over the connector using two-lane operation, with data rates of 10 and 20 Gbit/s (1250 and 2500 MB/s). Contents.Overview The USB 3.0 specification is similar to, but with many improvements and an alternative implementation. Earlier USB concepts such as endpoints and the four transfer types (bulk, control, and interrupt) are preserved but the protocol and electrical interface are different. The specification defines a physically separate channel to carry USB 3.0 traffic. Front view of a Standard-A USB 3.0 connector, showing its front row of four pins for the USB 1.x/2.0 backward compatibility, and a second row of five pins for the new USB 3.0 connectivity. The plastic insert is in the USB 3.0 standard blue color known as Pantone 300C.In USB 3.0, dual-bus architecture is used to allow both USB 2.0 (Full Speed, Low Speed, or High Speed) and USB 3.0 (SuperSpeed) operations to take place simultaneously, thus providing.
The structural topology is the same, consisting of a tiered star topology with a root hub at level 0 and hubs at lower levels to provide bus connectivity to devices.Data transfer and synchronization The SuperSpeed transaction is initiated by a host request, followed by a response from the device. The device either accepts the request or rejects it; if accepted, the device sends data or accepts data from the host. If the endpoint is halted, the device responds with a STALL handshake.
If there is lack of buffer space or data, it responds with a Not Ready (NRDY) signal to tell the host that it is not able to process the request. When the device is ready, sends an Endpoint Ready (ERDY) to the host which then reschedules the transaction.The use of and the limited amount of packets, combined with asynchronous notifications, enables links that are not actively passing packets to be put into reduced power states, which allows better power management.Data encoding The 'SuperSpeed' bus provides for a transfer mode at a nominal rate of 5.0 Gbit/s, in addition to the three existing transfer modes. Accounting for the encoding overhead, the raw data throughput is 4 Gbit/s, and the specification considers it reasonable to achieve 3.2 Gbit/s (400 MB/s) or more in practice.All data is sent as a stream of eight-bit (one-byte) segments that are scrambled and converted into 10-bit symbols via; this helps the receiver to decode correctly even in the presence of (EMI). Scrambling is implemented using a free-running (LFSR). The LFSR is reset whenever a COM symbol is sent or received.Unlike previous standards, the USB 3.0 standard does not specify a maximum cable length, requiring only that all cables meet an electrical specification: for copper cabling with 26 wires, the maximum practical length is 3 meters (9.8 ft).
Power and charging As with earlier versions of USB, USB 3.0 provides power at 5 volts nominal. The available current for low-power (one unit load) SuperSpeed devices is 150 mA, an increase from the 100 mA defined in USB 2.0. For high-power SuperSpeed devices, the limit is six unit loads or 900 mA (4.5 ), almost twice USB 2.0's 500 mA.: section 9.2.5.1 Power BudgetingThe term 'available current' can be misunderstood. It implies that if a low power device or a USB2 device is connected to a USB3 port it can only draw 150 mA or 500 mA from that port.
However, the available current for any USB device plugged into a USB3 port is 900 mA (unless it is charging port compliant) as defined by the USB3 spec. The actual current draw is determined by the device capability. The Vbus, pin 1, and Ground, pin 4, are the same for USB 1, 2, or 3. A USB2 with 2 USB2 connectors needing a total of 800 mA will draw full power from a single USB3 port. A USB2 phone will probably charge faster since 900 mA is 'available' to it.USB 3.0 ports may implement other USB specifications for increased power, including the for up to 1.5 A or 7.5 W, or, in the case of USB 3.1, the for charging the host device up to 100 W. Availability. Internal circuitboard and connectors of a USB 3.0 four-port hub, using a chipsetThe USB 3.0 Promoter Group announced on 17 November 2008 that the specification of version 3.0 had been completed and had made the transition to the (USB-IF), the managing body of USB specifications.
This move effectively opened the specification to hardware developers for implementation in future products.The first USB 3.0 consumer products were announced and shipped by in November 2009, while the first certified USB 3.0 consumer products were announced on 5 January 2010, at the Las Vegas (CES), including two motherboards by and.Manufacturers of USB 3.0 host controllers include, but are not limited to, Etron,. As of November 2010, Renesas and Fresco Logic have passed USB-IF certification. Motherboards for 's processors have been seen with Asmedia and Etron host controllers as well. On 28 October 2010, released the 17 3D featuring a Renesas USB 3.0 host controller several months before some of their competitors. Worked with Renesas to add its USB 3.0 implementation into its chipsets for its 2011 platforms.
At CES2011, unveiled a laptop called ' X500' that included USB 3.0 and, and released a new series of laptops that would include USB 3.0. As of April 2011, the and series were available with USB 3.0 ports, and, as of May 2012, the laptop series were as well; yet the USB root hosts failed to work at SuperSpeed under Windows 8. On 11 June 2012, announced new and with USB 3.0.Adding to existing equipment. Side connectors on a laptop computer. Left to right: USB 3.0 host, connector, USB 2.0 host. Note the additional pins on the top side of the USB 3.0 port.In laptop computers that lack USB 3.0 ports but have an slot, USB 3.0 ports can be added by using an ExpressCard-to-USB 3.0 adapter. Although the ExpressCard port itself is powered from a 3.3 V line, the connector also has a USB 2.0 port available to it (some express cards actually use the USB 2.0 interface rather than the true express card port).
However, this USB 2.0 port is only capable of supplying the power for one USB 3.0 port. Where multiple ports are provided on the express card, additional power will need to be provided. USB 3.0 Standard-A receptacle (top, in the blue color ' 300C'), Standard-B plug (middle), and Micro-B plug (bottom)A USB 3.0 Standard-A receptacle accepts either a USB 3.0 Standard-A plug or a USB 2.0 Standard-A plug. Conversely, it is possible to plug a USB 3.0 Standard-A plug into a USB 2.0 Standard-A receptacle. This is a principle of backward compatibility.
The Standard-A is used for connecting to a computer port, at the host side.A USB 3.0 Standard-B receptacle accepts either a USB 3.0 Standard-B plug or a USB 2.0 Standard-B plug. Backward compatibility applies to connecting a USB 2.0 Standard-B plug into a USB 3.0 Standard-B receptacle. However, it is not possible to plug a USB 3.0 Standard-B plug into a USB 2.0 Standard-B receptacle, due to a physically larger connector. The Standard-B is used at the device side.Since USB 2.0 and USB 3.0 ports may coexist on the same machine and they look similar, the USB 3.0 specification recommends that the Standard-A USB 3.0 receptacle have a blue insert ( 300C color). The same color-coding applies to the USB 3.0 Standard-A plug.: sections 3.1.1.1 and 5.3.1.3USB 3.0 also introduced a new Micro-B cable plug, which consists of a standard USB 1.x/2.0 Micro-B cable plug, with an additional 5-pin plug 'stacked' inside it. That way, the USB 3.0 Micro-B host connector preserved its backward compatibility with the USB 1.x/2.0 Micro-B cable plugs, allowing devices with USB 3.0 Micro-B ports to run at USB 2.0 speeds on USB 2.0 Micro-B cables.
However, it is not possible to plug a USB 3.0 Micro-B plug into a USB 2.0 Micro-B receptacle, due to a physically larger connector.Pinouts. USB 3.0 Standard-A plug (top) and receptacle (bottom), with annotated pinsThe connector has the same physical configuration as its predecessor but with five more pins.The VBUS, D−, D+, and GND pins are required for USB 2.0 communication. The additional USB 3.0 pins are two differential pairs and one ground (GNDDRAIN).
The two additional differential pairs are for SuperSpeed data transfer; they are used for full duplex SuperSpeed signaling. USB Micro-B USB 2.0 vs USB Micro-B SuperSpeed (USB 3.0)USB 3.0 and USB 2.0 (or earlier) Type-A plugs and receptacles are designed to interoperate.USB 3.0 Type-B receptacles, such as those found on peripheral devices, are larger than in USB 2.0 (or earlier versions), and accept both the larger USB 3.0 Type-B plug and the smaller USB 2.0 (or earlier) Type-B plug. USB 3.0 Type B plugs are larger than USB 2.0 (or earlier) Type-B plugs; therefore, USB 3.0 Type-B plugs cannot be inserted into USB 2.0 (or earlier) Type-B receptacles.Micro USB 3.0 (Micro-B) plug and receptacle are intended primarily for small portable devices such as smartphones, digital cameras and GPS devices. The Micro USB 3.0 receptacle is backward compatible with the Micro USB 2.0 plug.A receptacle for, which is an eSATA/USB combo, is designed to accept USB Type-A plugs from USB 2.0 (or earlier), so it also accepts USB 3.0 Type-A plugs. USB 3.1 In January 2013 the USB group announced plans to update USB 3.0 to 10 Gbit/s (1.25 GB/s). The group ended up creating a new USB specification, USB 3.1, which was released on 31 July 2013, replacing the USB 3.0 standard.
The USB 3.1 specification takes over the existing USB 3.0's SuperSpeed USB transfer rate, also referred to as USB 3.1 Gen 1, and introduces a faster transfer rate called SuperSpeed USB 10 Gbps, referred to as USB 3.1 Gen 2, putting it on par with a single first-generation channel. The new mode's logo features a caption stylized as SUPERSPEED+. The USB 3.1 Gen 2 standard increases the maximum to 10 Gbit/s (1.25 GB/s), double that of SuperSpeed USB, and reduces line encoding overhead to just 3% by changing the to. The first USB 3.1 Gen 2 implementation demonstrated real-world transfer speeds of 7.2 Gbit/s.The USB 3.1 standard is backward compatible with USB 3.0 and USB 2.0. It defines the following transfer modes:.
USB 3.1 Gen 1 – SuperSpeed, 5 Gbit/s (0.500 GB/s) data signaling rate over 1 lane using 8b/10b encoding; the same as USB 3.0. USB 3.1 Gen 2 – SuperSpeed+, new 10 Gbit/s (1.212 GB/s) data rate over 1 lane using 128b/132b encoding.The nominal data rate in bytes accounts for bit-encoding overhead.
The physical SuperSpeed bit rate is 5 Gbit/s. Since transmission of every byte takes 10 bit times, the raw data overhead is 20%, so the byte rate is 500 MB/s, not 625. Similarly, at SS+ rate the encoding is 128/132, so transmission of 16 bytes physically takes 16.5 bytes, or 3% overhead.
Therefore, the byte-rate at SS+ is 1.25. 0.97 GB/s=1.212 GB/s. In reality the SS bus has some additional service overhead (link management, protocol response, host latencies), so the best-case achievable data rates are about 10% smaller.This rebranding of USB 3.0 as 'USB 3.1 Gen 1' allows manufacturers to advertise products with transfer rates of only 5 Gbit/s as 'USB 3.1,' omitting the generation. USB 3.2 On 25 July 2017, a press release from the USB 3.0 Promoter Group detailed a pending update to the specification, defining the doubling of bandwidth for existing USB-C cables. Under the USB 3.2 specification, released 22 September 2017, existing SuperSpeed certified USB-C 3.1 Gen 1 cables will be able to operate at 10 Gbit/s (up from 5 Gbit/s), and SuperSpeed+ certified USB-C 3.1 Gen 2 cables will be able to operate at 20 Gbit/s (up from 10 Gbit/s). The increase in bandwidth is a result of multi-lane operation over existing wires that were intended for flip-flop capabilities of the USB-C connector.The USB 3.2 standard is backward compatible with USB 3.1/3.0 and USB 2.0.
