Ubuntu. USB keeps disconnecting or not recognizing
All of a sudden, USB seems to be haywire. I was on Jaunty but upgraded to Karmic, but that did not fix anything.
USB devices will either not be recognized when I plug them in (a usb game pad or my blackberry), or will be recognized, then disconnect
When it does show up, after a few minutes, dmesg will show this:
[24931.888638] usb 2-9: USB disconnect, address 12
[24945.152039] hub 2-0:1.0: unable to enumerate USB device on port 9
It'll keep disconnecting, then slightly later recognize the device again, with a new address.
