I got an wifi adapter from mediatek. The MT7612U are built in kernel and thus should not have any issues, but the internet speed is way slower than should be. Eventually the speed get's normal but often it's get really slow.
Those times, if I try to check the lsusb it's hangs forever and if I reboot it's keeping looping in a message about vendor issues (I forgot how I can check this message in command line, since I am forced to do a hard reset when this happens)

Any suggestion in how I can debug it?
