USB driver problems on Linux
In some conditions, the USB drivers installed by NoMachine could interfere with the system utilities for suspending PC activities. In particular, it has been reported that on a Debian host, the USB drivers were preventing pm-suspend from working. The pm-suspend command should lead the computer to a suspended status.
Users can disable the USB service by removing the drivers.
Make sure that all player instances are closed and that no NX session is running on the host as they may be using the USB module and make it impossible to be removed.
1. Run 'lsmod | grep nxusb'.
2. (optional) If in step 1 you see nxusb module listed as a loaded module, e.g.
nomachine@raingod:~$ lsmod | grep nxusb
nxusb 34256 0
run: 'sudo rmmod nxusb'
3. Run 'sudo rm /usr/NX/bin/drivers/nxusb.ko'
