It doesn’t sound like missing device drivers or anything similar to me. There is no way for these devices to ever be “removed”, “disconnected”, or moved to a different physical USB location. You can try to solder bridge the pins 4 and 5 in order to get a stable ground on the USB. Knee-jerk response would be it looks like you may not have enough decoupling. FTDI drivers may be distributed in any form as long as license information is not modified.

Did you check all the way to your connector and from that through the cable?

I’m using self powered configuration, so the chip gets its power from USB port directly.
This question has been asked ftddi and already has an answer. I believe that part occurs very early during enumeration so it could be something wrong at a fairly low level.

Sample output snippets with two ftdi devices connected Bus Device On Windows I got unknown device and then Windows disables it because thinks it works wrong. Without this there is no power at all on the pins of the chip. Knee-jerk ft223d would be it looks like you may not have enough decoupling.

Yes, you are liunx, here it is: You must use the Windows RT build for this platform. You might want to double check that. These FTDIs won’t be my favourites for sure.
