I can reproduce this is Lucid. I also noticed the following interesting fact. On the non-working system dmesg ends with:
[ 354.692045] usb 1-4: new high speed USB device using ehci_hcd and address 9 [ 369.748057] hub 1-0:1.0: unable to enumerate USB device on port 4 while on the working system dmesg has: Mar 25 22:25:06 fueron kernel: [52584.590036] usb 1-2: new high speed USB device using ehci_hcd and address 6 Mar 25 22:25:07 fueron kernel: [52585.840290] hub 1-0:1.0: unable to enumerate USB device on port 2 Mar 25 22:25:08 fueron kernel: [52586.380046] usb 2-2: new full speed USB device using ohci_hcd and address 4 Mar 25 22:25:08 fueron kernel: [52586.595617] usb 2-2: not running at top speed; connect to a high speed hub Mar 25 22:25:08 fueron kernel: [52586.618785] usb 2-2: configuration #1 chosen from 1 choice Mar 25 22:25:08 fueron kernel: [52586.632921] scsi9 : SCSI emulation for USB Mass Storage devices Mar 25 22:25:08 fueron kernel: [52586.633144] usb-storage: device found at 4 Mar 25 22:25:08 fueron kernel: [52586.633151] usb-storage: waiting for device to settle before scanning Mar 25 22:25:13 fueron kernel: [52591.633227] usb-storage: device scan complete etc. So it seems like the working system tries ehci_hcd, fails, then tries ohci_hcd, and works; while the non-working just tries ehci_hcd and fails. -- Sansa Fuze mp3 player does not auto-mount https://bugs.launchpad.net/bugs/501769 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
