Public bug reported: When connecting my usb stick to the computer, it is not automatically discovered anymore. Even 'lsusb -v' does not show anything beside the usb hub.
Instead, 'cat /proc/kmsg' produces messages like [17180190.832000] usb 1-2: new full speed USB device using uhci_hcd and address 5 [17180191.336000] usb 1-2: new full speed USB device using uhci_hcd and address 6 [17180191.840000] usb 1-2: new full speed USB device using uhci_hcd and address 7 [17180192.344000] usb 1-2: new full speed USB device using uhci_hcd and address 8 [17180192.848000] usb 1-2: new full speed USB device using uhci_hcd and address 9 and so on, about two messages per second. The address numbers go up till 127 and then start again at 0. The problem is obviously related to uhci_hcd.ko, since removing it stops the messages (and reloading it starts them again). I have this bug for 2 days now, the last time I used the stick was about two weeks ago, when everything was functioning properly. I had already migrated to dapper then, so it must be some issue with the last two weeks' updates. I have been able to resolve the problem once by inserting and removing various modules like sd_mod, ehci_hcd, uhci_hcd, usb_storage, but I haven't been able to reproduce it :-/ Loading sd_mod, by the way, gives the following error message: Driver 'sd' needs updating - please use bus_type methods but it loads nonetheless. Any help would be appreciated! ** Affects: linux-source-2.6.12 (Ubuntu) Importance: Untriaged Status: Unconfirmed ** Attachment added: "output of dmesg" http://librarian.launchpad.net/3140216/dmesg.txt -- uhci_hcd generates flood of kernel messages while failing to mount usb stick https://launchpad.net/bugs/50757 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
