I've been getting this (very real & unsolved) bug with my Imation Apollo 25 PHDD-160GB (Apollo 2.5" Portable HDD).
uname -a: Linux aldor 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:04:26 UTC 2009 i686 GNU/Linux distribution: Ubuntu Karmic Koala 9.10 (tho it has affected the last 3 distributions) The "unable to enumerate USB device on port X" message appears about 5 times per second on tty1-6 (if I switch away from X), and they also appear about 5 times per second in /var/log/kern.log It's NOT like other similar-sounding bugs which are harmless aside from an annoying message: my bug prevents me from using my USB drive at all. Usually I've been able to wait about 10-30 minutes, and the messages will finally stop appearing and the drive will mount, but the drive never mounts until the messages stop. I haven't been able to find any cause for the messages or them stopping. However, it's stopped working altogether now -- I've had it plugged in overnight, and it hasn't mounted. What this bug is NOT: * it is not a device problem (the drive works fine in Windows, and works fine once it's mounted). * it is not a power supply problem (it happens whether or not I plug in the second USB plug for extra power. Again, it works fine in Windows with just one plugged in) * it is not something I can fix with a kernel upgrade (I've been through 3 distributions and about 15 kernel upgrades: always the same problem -- some other people have had luck with kernel upgrades, but then have had a regression with a subsequent upgrade, which indicates to me that the problem only disappears temporarily during some phases of the moon) * it is not a problem with my USB ports (the USB ports all work properly for my camera & mouse, and this problem occurs with the drive on all ports) I've looked at all the bugs that contain this message for Ubuntu, Fedora, Debian, etc, and no solutions yet -- most of them relate to different problems. I understand that this message can occur for all sorts of problems, but I haven't found anything else that relates to this problem -- can somebody help me pin it down a bit better? Should I post a new bug, or is this existing one adequate? -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
