This comment is coming from someone without V5 but has had various connection issues to devices with USB (usually arduino related). Just trying to throw something in I didn't see here previously that may help someone.
1 - I have found some computers don't work with a given cable, but work with a different cable. Try a few cables. I don't know the differences, but I have an arduino board that will only work with one specific cable on my Lenovo T440s. Strange.
2 - I have found differences wits the USB port standards, ie usb 2, usb 3. I have had things connect using an older USB 2 that didn't with the USB3. Its supposed to work in either, and I have heard from others that have no issue, so I suspect its a hardware implementation/driver issue, but this has burned me before.
3 - I have also found differences when a device is plugged into a USB hub vs. plugged in direct. I've had it work with the hub and not direct, and also had it NOT work with the hub and work direct. Again... No clue, and no real desire to dig into the issue either.
