Hello I have problem with a particular type of USB key (3SYSTEM's POCKET DISK) on my embedded Linux2.6.12 system. From USB protocol analyzer I saw the USB key device failed to ACK a data packet (size 31 bytes) from USB host controller and timeout error occurred. USB host controller re-sends the same data packet 3 times and the USB device does not send anything to the USB host controller.
However, this USB storage key works well with PC Linux 2.6.11(fadora core (2.6.11-1.1369_FC4). The kernel log is attached below usb 2-1: Product: USB FLASH DISK usb 2-1: Manufacturer: 3SYSTEM usb 2-1: SerialNumber: 0307110057580 scsi0 : SCSI emulation for USB Mass Storage devices Vendor: 3SYSTEM Model: USB FLASH DISK Rev: 1.00 Type: Direct-Access ANSI SCSI revision: 02 SCSI device sda: 512000 512-byte hdwr sectors (262 MB) sda: Write Protect is off sda: assuming drive cache: write through SCSI device sda: 512000 512-byte hdwr sectors (262 MB) sda: Write Protect is off sda: assuming drive cache: write through /dev/scsi/host0/bus0/target0/lun0:<7>usb-storage: queuecommand called end_request: I/O error, dev sda, sector 0 Buffer I/O error on device sda, logical block 0 Buffer I/O error on device sda, logical block 0 unable to read partition table Attached scsi removable disk sda at scsi0, channel 0, id 0, lun 0 storage: usb_stor_Bulk_reset called usb-storage: usb_stor_control_msg: rq=ff rqtype=21 value=0000 index=00 len=0 usb-storage: Soft reset: clearing bulk-in endpoint halt usb-storage: usb_stor_control_msg: rq=01 rqtype=02 value=0000 index=81 len=0 usb-storage: usb_stor_clear_halt: result = 0 usb-storage: Soft reset: clearing bulk-out endpoint halt usb-storage: usb_stor_control_msg: rq=01 rqtype=02 value=0000 index=02 len=0 usb-storage: usb_stor_clear_halt: result = 0 usb-storage: Soft reset done usb-storage: scsi cmd done, result=0x70000 usb-storage: *** thread sleeping. usb-storage: queuecommand called usb-storage: *** thread awakened. usb-storage: Command MODE_SENSE (6 bytes) usb-storage: 1a 00 3f 00 c0 00 usb-storage: Bulk Command S 0x43425355 T 0x12 L 192 F 128 Trg 0 LUN 0 CL 6 usb-storage: usb_stor_bulk_transfer_buf: xfer 31 bytes usb-storage: Status code 0;
