Hello Ike,

i'm back at this problem.
I have loaded module ideapad_laptop with modification as above.

On triggering the hardware wifi button on->off->on i get the following
messages:

[  730.712030] usb 3-5: USB disconnect, device number 4

Other function buttons (e.g. screen brightness adjustment) also produce
messages as above "notified. event: 0x80."
