Hi, I'm starting to become convinced that flaky as the transport driver may be it is as nothing to the devices it talks to :-(
Anyway I'm still getting intermittent problems with talking to the Freecom USB sticks which I'd like to understand in better detail. At least one of the commands (MODE_SENSE) seems to fail whenever the device is plugged in: usb-storage: Command MODE_SENSE (6 bytes) usb-storage: 1a 00 3f 00 ff 00 00 00 00 00 00 00 usb-storage: Bulk command S 0x43425355 T 0x6 Trg 0 LUN 0 L 255 F 128 CL 6 hci_submit_urb: 122765->122766 usb-storage: Bulk command transfer result=0 usb-storage: usb_stor_transfer_partial(): xfer 255 bytes hci_submit_urb: 122767->122768 error on received packet: cc=9,urb->status = -121 urb :89fce2c0 next :00000000 dev :8826dc00 pipe :C0008280 (type 3) status :-121 transfer_flags :00000008 transfer_buffer :895ed000 transfer_buffer_length:255 actual_length :12 setup_packet :00000000 start_frame :10223 number_of_packets :0 interval :0 error_count :0 context :8826db74 complete :c0132bc0 usb-storage: usb_stor_bulk_msg() returned -121 xferred 12/255 usb-storage: usb_stor_transfer_partial(): unknown error usb-storage: Bulk data transfer result 0x2 The cc code from my transport indicates an DataUnderrun, however I suspect it could be the device just give short replies. However if I return a bad status I assume it just gets ignored by the higher level? As all these commands are as I understand it meant to be SCSI commands encapsulated over USB I thought I'd have a closer look at the contents: contents:0xb 0x0 0x0 0x8 0x0 0x1 0xfffffff4 0x0 0x0 0x0 0x2 0x0 However I cannot find where the MODE_SENSE command is documented (although granted I've not read every document on the T10 site). Can anyone point me in the right direction? -- Alex, homepage: http://www.bennee.com/~alex/ 'In the Fyres of Struggle let us bake New Men, who Will Notte heed the old Lies.'
