suspend no longer supported

[Thermionix]

I'm using ubuntu 11.04 and found the the echo suspend line didn't work.

I searched and found; https://bbs.archlinux.org/viewtopic.php?id=95659 - In kernels up to 2.6.32, you could also specify "suspend", meaning that the device should remain suspended and autoresume was not allowed. This setting is no longer supported.

solution - replace suspend with; echo "0" > "/sys/bus/usb/devices/$port/power/autosuspend" echo "auto" > "/sys/bus/usb/devices/$port/power/level"
