Two problems here. The first is that even after poking in SCSI's core, modprobing usb-storage hangs and is unkillable:
Module Size Used by usb-storage 53360 2 (initializing) ... scsi_mod 83376 3 [usb-storage sd_mod sg] ... usbcore 49088 1 [usb-storage dc2xx hid uhci]
The dmesg (w/ verbose) looks like this:
SCSI subsystem driver Revision: 1.00 Initializing USB Mass Storage driver... usb.c: registered new driver usb-storage usb-storage: act_altsettting is 0 usb-storage: id_index calculated to be: 36 usb-storage: Array length appears to be: 64 usb-storage: Vendor: Sandisk usb-storage: Product: ImageMate SDDR-31 usb-storage: USB Mass Storage device detected usb-storage: Endpoints: In: 0xc749a880 Out: 0xc749a894 Int: 0x00000000 (Period 0) usb-storage: New GUID 078100020000000000000000 usb-storage: GetMaxLUN command result is -32, data is 220 usb-storage: clearing endpoint halt for pipe 0x80000480 usb-storage: Transport: Bulk usb-storage: Protocol: Transparent SCSI usb-storage: *** thread sleeping. scsi0 : SCSI emulation for USB Mass Storage devices usb-storage: queuecommand() called usb-storage: *** thread awakened. usb-storage: Command INQUIRY (6 bytes) usb-storage: 12 00 00 00 ff 00 00 00 15 bb 1a c0 usb-storage: Bulk command S 0x43425355 T 0x1 Trg 0 LUN 0 L 255 F 128 CL 6 usb-storage: Bulk command transfer result=0 usb-storage: usb_stor_transfer_partial(): xfer 255 bytes usb-storage: usb_stor_bulk_msg() returned 0 xferred 56/255 usb-storage: Bulk data transfer result 0x1 usb-storage: Attempting to get CSW... usb-storage: command_abort() called usb-storage: Bulk status result = -104 usb-storage: Bulk reset requested usb-storage: Bulk soft reset failed -32 usb-storage: -- transport indicates transport failure usb-storage: Fixing INQUIRY data to show SCSI rev 2 usb-storage: scsi cmd done, result=0x70000 usb-storage: *** thread sleeping.
Bug or no? It never finishes initialization, and never wakes up, and /dev/sda never works properly. SCSI reads:
/proc/scsi$ cat scsi Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: Model: Rev: Type: <NULL> ANSI SCSI revision: ffffffff
