kernel version : 4.14.171 , also tried testing kernel 5.4 with the same
results.

there's no error during enumeration , errors occur as soon as I activate
the device in AP mode or client mode , if the device is doing nothing I
get no errors.

usb works fine with usb storage , I tried another adapter with rt2800 
driver and got the same exact problem.
