[Question #247956]: Wifi doesn't work in Lubuntu 14.04


New question #247956 on AC100_enablement:

Hello I have just installed Lubuntu 14.04 on a AC100. I cannot make wifi work in Lubuntu anyway.
I have set up dual-boot with Android and when I boot in it, wifi works flawlessly.
I have a feeling that there is some problems with USB power management.

The kernel doesn't load the rt2800usb module. There are some errors in dmes of the type:
usb 1-1: device descriptor read/64, error -71
usb 1-1: device not accepting address 4, error -71

I tried to boot the kernel with the "usbcore.autosuspend=-1" and "usbcore.old-scheme-first=1" options.
I have tried to unplug everything and wait 5 minutes before rebooting.

here some useful logs:
