Maybe insufficient power causes some of the problems? My Iomega prestige external harddrive gives the following in dmesg when connected to a USB3.0 port in Ubuntu 12.10:
[26060.639311] xhci_hcd 0000:02:00.0: Timeout while waiting for address device command [26065.837435] xhci_hcd 0000:02:00.0: Timeout while waiting for address device command [26066.041256] usb 4-2: device not accepting address 2, error -62 [26066.041557] xhci_hcd 0000:02:00.0: Bad Slot ID 1 [26066.041565] xhci_hcd 0000:02:00.0: Could not allocate xHCI USB device data structures [26066.041575] hub 4-0:1.0: couldn't allocate port 2 usb_device However, there is an extra USB connector on the cable that can also be plugged in for extra power. With that, the drive works fine with USB 3.0. (Connected to a USB 2.0 port, it works fine even without the extra power). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/775543 Title: 1033:0194 xhci_hcd: Timeout while waiting for a slot - Issue with USB3 hard disk on 11.04 x86_64 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/775543/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
