This has happened to me many times too. Most recently today with Ubuntu 11.04 (Linux phoebe 2.6.38-11-generic #50-Ubuntu SMP Mon Sep 12 21:17:25 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux)

I _was_ running my mouse through the hub in my monitor. Now I've removed it from the hub, and will test with nothing running off the hub. Failing that, I will unplug the hub. It would be a shame, because the hub worked perfectly for years on older machines with earlier Ubuntu versions. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/795626 Title: ehci_hcd fatal error - USB devices randomly crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/795626/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
