My os is windows 10. I think I’ve found some problems with FTDI drivers: the FT2232H mini module generates 4 USB-Serial converter instead of two. All of them have “usb migration problem”.
I’ve tried to reinstall the drivers with the latest one from FTDI website, but it doesn’t work. I am stuck because it does the same on other computers.
I’ve try to ask to FTDI support: lets see if they reply.
EDIT: I’ve found that you have to connect also V3V3 to VIO in the FT2232H Mini Module:
CN2, pins 1, 3 & 5 ----> CN2 pins 11 & 21 and CN3, pins 12 & 22
This solve the problem of the USB driver malfunction.
Anyway the debugger session doesn’t start: same messages as above: unable to open ftdi device…
