[Bug 85488] Re: some usb_devices fault if usb_suspend enabled

[fishor]

This should work for permanent settings:

sudo echo "options usbcore autosuspend=-1" > /etc/modprobe.d/usb_suspend
after this us should reboot.

this is for temporary:

sudo su
echo "-1" > /sys/module/usbcore/parameters/autosuspend

after this you need replug you scanner.

-1 mean - disable autosuspend
2 mean - enable autosuspend with delay 2 seconds
