I was just wondering if it was in the storage driver, the low level host controller driver or maybe the USB core code. If all USB devices stop working, it suggests one of the latter two, otherwise it suggests the former and shouldn't even stop other USB storage devices from working. > ohci_hcd: 2004 Feb 02 USB 1.1 'Open' Host Controller (OHCI) Driver (PCI) I didn't think OHCI was very common on PCs but I guess > Dmesg of an unsuccessful plugging in of the drive: > > usb 3-5: new high speed USB device using address 5 > scsi2 : SCSI emulation for USB Mass Storage devices Yuk! The USB storage code has a certain amount of statefulness, so if it's hanging for that drive once, it may stop it working for the rest of the uptime. If the bug is in the USB storage code, you'll probably find that other storage devices still work, otherwise it may be somewhere else.
