I have had the USB hub not working a few times.
When it stopped working, I took it to work. It worked fine at work. Then, I brought it back home and it worked fine at home too!
It worked for 4 months after that and tonight again stopped working. So, the monitor works fine except that the hub shows as an unknown USB device under the device manager in XP.
This time, I shut down the monitor and unplugged it from AC power. While unplugged, I pressed the on off switch 2 or 3 times.
Then, after about 30 seconds of having it unplugged, I plugged it back in and powered it up and it is working just fine again.
If you experience this problem with this monitor and try this approach and the problem remains, please post here.
