Windows: FX3 is enumerated only on USB 2.0 after firmware programming

[PavelKumpan]

Hello,

I would like to use the FX3 device & fx3lafw on the Windows computer. However when I program the firmware, the fx3lafw device is enumerated only if I use USB 2.0 cable or USB 2.0-only port. If I use USB 3 port & cable, the device appears for few seconds in the device manager and then disappears. It is also not possible to list it via libusb.

This is UART output for USB 2.0 cable.:

Good moaning!
