I have a new workstation running 64 bits 2.6.34 gentoo sources. It's an HP p6520y (AthlonIIX4) with 6GB and lsusb reports an Alcor Micro 21-in-1 Flash Card Reader.
I have no usb storage devices plugged in and I see in my dmesg many of the following messages: usb-storage: queuecommand called usb-storage: *** thread awakened. usb-storage: Command TEST_UNIT_READY (6 bytes) usb-storage: 00 00 00 00 00 00 usb-storage: Bulk Command S 0x43425355 T 0x5473 L 0 F 0 Trg 0 LUN 1 CL 6 usb-storage: usb_stor_bulk_transfer_buf: xfer 31 bytes usb-storage: Status code 0; transferred 31/31 usb-storage: -- transfer complete usb-storage: Bulk command transfer result=0 usb-storage: Attempting to get CSW... usb-storage: usb_stor_bulk_transfer_buf: xfer 13 bytes usb-storage: Status code 0; transferred 13/13 usb-storage: -- transfer complete usb-storage: Bulk status result = 0 usb-storage: Bulk Status S 0x53425355 T 0x5473 R 0 Stat 0x1 usb-storage: -- transport indicates command failure usb-storage: Issuing auto-REQUEST_SENSE usb-storage: Bulk Command S 0x43425355 T 0x5474 L 18 F 128 Trg 0 LUN 1 CL 6 usb-storage: usb_stor_bulk_transfer_buf: xfer 31 bytes usb-storage: Status code 0; transferred 31/31 usb-storage: -- transfer complete usb-storage: Bulk command transfer result=0 usb-storage: usb_stor_bulk_transfer_sglist: xfer 18 bytes, 1 entries usb-storage: Status code 0; transferred 18/18 usb-storage: -- transfer complete usb-storage: Bulk data transfer result 0x0 usb-storage: Attempting to get CSW... usb-storage: usb_stor_bulk_transfer_buf: xfer 13 bytes usb-storage: Status code 0; transferred 13/13 usb-storage: -- transfer complete usb-storage: Bulk status result = 0 usb-storage: Bulk Status S 0x53425355 T 0x5474 R 0 Stat 0x0 usb-storage: -- Result from auto-sense is 0 usb-storage: -- code: 0xf0, key: 0x2, ASC: 0x3a, ASCQ: 0x0 usb-storage: Not Ready: Medium not present usb-storage: scsi cmd done, result=0x2 usb-storage: *** thread sleeping. Any ideas who/what is doing this? How to debug? Bill -- Bill Longman Εν αρχη ην ο λογος
