</div>That's probably the easiest and most reliable way :)<br>
<br>
In the meantime, you could always check whether your USB ports are set<br>
to automatic power management:<br>
<br>
[davidp@columbia:~]$<br>
cat /sys/bus/usb/devices/usb*/power/level<br>
auto<br>
auto<br>
<br>
If you get "auto", you could try forcing them to stay on - e.g. as root:<br>
<br>
echo on > /sys/bus/usb/devices/usb1/power/level<br>
<br>
Worth a try at least, if you're interested.<br>
<br>
Of course, you'd need to figure out which "usb$n" to use, depending on<br>
which port it's connected to - or just set them all to on:<br>
<br>
for file in /sys/bus/usb/devices/usb*/power/level; \<br>
do echo "on" > $file; done<br>
<br>
Whether the above will actually make a difference, I don't know, but<br>
could be worth a try if you're curious. If you do, report back whether<br>
it helped, so everyone knows if that's a potential fix for anyone else<br>
who experiences the same problem :)<br>
