Thanks to both of you.
The port is black, but it has been working for few months until I shutdown
/ change session (I can't log back to previous session for reasons) so I
believe that the port by itself isn't the bad guy.
It keeps appearing as USB 2 ("high-speed") when I plug it and also when I
run uhd_find_devices
@Cedric I made sure to plug at max both ends
Thank you again
Regards,
Rodolphe
