No, it was before Gutsy. To me, it happened after some upgrade in Edgy. >If it was the autosuspend, yes we have workaround but, how about getting >USB 2.0 and autosuspend to work at the same time. If it was not the >autosuspend, then we would like more debug done to see where's the >conflict in the echi_hcd module and hopefully get it fixed. My motherboard has most probably USB 1 ports. When I had the problem in Edgy, I had to remove the ehci_hcd module to solve it. Now with Gutsy ehci_hcd is not loaded any more, and everything works. Even If I load ehci_hcd by hand everything keeps working. -- ehci_hcd module causes I/O errors in USB 2.0 devices https://bugs.launchpad.net/bugs/88746 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
