Tomaz says that the bug appears to be fixed in 2.6.17-10.33. I have this problem exactly like described above and as far as I can tell this system is 2.6.17-10.34.
The dmesg rows are: ... [17196590.352000] usb 1-1: new full speed USB device using ohci_hcd and address 2 [17196590.552000] usb 1-1: not running at top speed; connect to a high speed hub [17196590.564000] usb 1-1: configuration #1 chosen from 1 choice ... After restarting ohci_hcd and ehci_hcd, high speed USBs are detected correctly. -- USB storage not running at top speed since Edgy beta https://launchpad.net/bugs/66115 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
