I have some even more bizarre behavior to report with regards to this bug. The above symptoms only seem to occur when the usb key was plugged into a Windows XP machine right before trying to mount it in Ubuntu. I have been able to reproduce this multiple times.
Case 1: attach to a XP box --> safely remove --> attach to an Ubuntu box --> experience problems described above. Case 2: attach to a XP box --> safely remove --> attach to a Vista box --> safely remove --> attach to an Ubuntu box --> key mounts with no problems. Case 3: attach to an Ubuntu box --> safely remove --> attach to a Windows XP box --> safely remove --> re-attach to Ubuntu box --> experience problems described above. You can go through all the permutations you'd like, but it seems to be the XP -> Ubuntu combination that causes the problems. Is it possible that XP leaves the key is some sort of bad state that then clashes with Ubuntu? Like I said, bizarre ..... I think this makes things even more unclear. It may not even be an Ubuntu bug. In my case, though, it's repeatable, so I thought it noteworthy. -- Unable to enumerate usb device https://bugs.launchpad.net/bugs/318085 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
