For some reason this seems to be hardware-dependant. I have so far "collected" four USB SATA docking stations or adapters. I do not see this bug on USB 2 at all (ICH 10). On USB 3 (Renesas/NEC) I see it on one of two docking stations. On that one, I see it every time, and on the other never at all. Also, I never saw this when disconnecting a stick, a memory card or a phone.
Just with one docking station (Icy Box IB 111 with integrated hub). It's not the hub either, second USB 3 dock works perfectly through the hub of the one producing the error. Also, the dock producing the error is hotplug capable, according to Icy Box. Strange, but the hardware dependancy is obvious. Also, I noticed when I correctly disconnect a drive on USB 3, kern.log says Oct 20 01:39:08 FSC kernel: [12509.993534] usb 10-1.4: reset SuperSpeed USB device number 19 using xhci_hcd Oct 20 01:39:08 FSC kernel: [12510.011574] xhci_hcd 0000:02:00.0: xHCI xhci_drop_endpoint called with disabled ep ffff88003eec3b80 Oct 20 01:39:08 FSC kernel: [12510.011578] xhci_hcd 0000:02:00.0: xHCI xhci_drop_endpoint called with disabled ep ffff88003eec3bc0 Oct 20 01:39:08 FSC kernel: [12510.028700] usb 10-1.4: USB disconnect, device number 19 Oct 20 01:40:42 FSC kernel: [12604.084118] usb 10-1: USB disconnect, device number 17 Oct 20 01:40:42 FSC kernel: [12604.084122] usb 10-1.1: USB disconnect, device number 18 When I disconnect with the error, nothing gets written to kern.log at all. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/466575 Title: secure remove of external USB-HDD produces error To manage notifications about this bug go to: https://bugs.launchpad.net/udisks/+bug/466575/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
