usb disconnects

Hello, i have a USB DAC plugged into my homeserver and every now and then (seems to be random) the device disconnects resulting in a loud noise in my speakers.

tauron kernel: hub 4-0:1.0: port 3 disabled by hub (EMI?), re-enabling...

this is the line i am getting. i tried to disable power control for all usb ports, but it doesnt seem to help.

Anyone an idea?

Re: usb disconnects

Try removing /usr/lib/udev/rules.d/42-usb-hid-pm.rules, so "power/control" never gets set to "auto".
