Comments:

I'm trying to debug the process why the usb is getting deauthenticated and not able to connect again after that. I'll post my findings!

FYI: I'm using the device in a dongle of 60cm long. I'll try to use without it for testing some usb expander issues messing the device..but I won't bet in it.
