Resuming Thinkpad x260 from # sysctl -w hw.acpi.sleep.state=3

[Ramiro Aceves <ea1abz%gmail.com@localhost>]

Hello,

When I suspend my amd64 Thinkpad x260 system issuing:

# sysctl -w hw.acpi.sleep.state=3

and return back, my external USB keyboard (2.4 GHz RF one) no longer 
works. Even disconnecting and reconnecting physically does not work. 
External mouse continues working well.

¿Is there any way of resurrecting the USB keyboard without rebooting the 
system? Thinkpad own keyboard works just fine after the suspend state.

Regards.
Ramiro.
