Hi, my original bugreport (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/291021) was duped to this bug, although I am not entirely sure it is the same problem.
A quick summary of the problem: I have an external hard drive (Toshiba PX1220E-1G25, 250 GB, 3,5'') that is not recognized under linux ( tested on Ubuntu 8.04 and Debian Lenny). It works fine under Windows XP. The device is actually a Dura Micro Model 501-B101 (or maybe B112) HDD enclosure. Symptoms: * The following message is visible in dmesg: usb 5-8: new high speed USB device using ehci_hcd and address 4 This message is repeated from time to time using different address number. * The disk does not show up under the lsusb and fdisk -l commands. If I remove the ehci_hcd module, then the device starts to work. The 'trick' mentioned in this bug (modifying the 60-persistent-storage.rules file, the 40-permissions.rules file, and restarting udev) does not solve the problem, at least not on hardy. Please let me know if I can provide further information. With ehci_hcd enabled: Output of dmesg: [ 7359.852048] usb 5-7: new high speed USB device using ehci_hcd and address 4 Output of uname -a: Linux 2.6.24-21-generic #1 SMP Tue Oct 21 23:43:45 UTC 2008 i686 GNU/Linux Output of lsb_release -a: Distributor ID: Ubuntu Description: Ubuntu 8.04.1 Release: 8.04 Codename: hardy Output of lsusb -v: See the attachment of the original bug, -- USB Hard Drive Not Accessible https://bugs.launchpad.net/bugs/264789 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
