As per the forum thread, I've reported the bug upstream and been asked to work through a git bisect to locate the commits between 2.6.37 final release and 2.6.38rc1 that first caused the problem. This is in progress and I expect to complete on 18th March.
In doing this testing I'm noticing that this issue may be linked to lsusb hanging. I've observed that on "bad" kernels, lsusb hangs while this device is plugged and then completes when the device cable is removed. On "good" kernels, lsusb reports the device correctly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/735466 Title: USB device fails to connect - device descriptor read/64, error -110 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
