Dear Alan, I've tested usb-storage with the 2.6.0-test2-bk2 kernel version, It seems that 2.6 kernel version is stable. However, 2.4 version is unstable.
The host controller mPD270100 of NEC and VT6202 of VIA. When it tested in a high speed multihub, it operated about two weeks. However, it became the following errors when the number of devices was one. I think that it is not failure of a device. Is it the problem of error handling? This error was generated in the latest kernel 2.4.22. usb-storage: usb_stor_transfer_partial(): xfer 2048 bytes usb-storage: usb_stor_bulk_msg() returned 0 xferred 2048/2048 usb-storage: usb_stor_transfer_partial(): transfer complete usb-storage: Bulk data transfer result 0x0 usb-storage: Attempting to get CSW... usb-storage: Bulk status result = 0 usb-storage: Bulk status Sig 0x53425355 T 0x7862f6 R 0 Stat 0x0 usb-storage: scsi cmd done, result=0x0 usb-storage: *** thread sleeping. usb-storage: queuecommand() called usb-storage: *** thread awakened. usb-storage: Command READ_10 (10 bytes) usb-storage: 28 00 00 02 e5 23 00 00 01 00 00 00 usb-storage: Bulk command S 0x43425355 T 0x7862f7 Trg 0 LUN 0 L 2048 F 128 CL 12 usb-storage: Bulk command transfer result=0 usb-storage: usb_stor_transfer_partial(): xfer 2048 bytes usb-storage: usb_stor_bulk_msg() returned 0 xferred 2048/2048 usb-storage: usb_stor_transfer_partial(): transfer complete usb-storage: Bulk data transfer result 0x0 usb-storage: Attempting to get CSW... usb-storage: Bulk status result = 0 usb-storage: Bulk status Sig 0x53425355 T 0x7862f7 R 0 Stat 0x0 usb-storage: scsi cmd done, result=0x0 usb-storage: *** thread sleeping. usb-storage: queuecommand() called usb-storage: *** thread awakened. usb-storage: Command READ_10 (10 bytes) usb-storage: 28 00 00 02 e5 24 00 00 3f 00 00 00 usb-storage: Bulk command S 0x43425355 T 0x7862f8 Trg 0 LUN 0 L 129024 F 128 CL 12 usb-storage: command_abort() called usb-storage: Bulk command transfer result=-104 usb-storage: -- transport indicates command was aborted usb-storage: Bulk reset requested usb_control/bulk_msg: timeout usb-storage: Bulk soft reset failed -110 usb-storage: scsi command aborted usb-storage: *** thread sleeping. usb-storage: queuecommand() called usb-storage: *** thread awakened. usb-storage: Command TEST_UNIT_READY (6 bytes) usb-storage: 00 00 00 00 00 00 00 00 3f 00 00 00 usb-storage: Bulk command S 0x43425355 T 0x7862f9 Trg 0 LUN 0 L 0 F 0 CL 12 usb-storage: Bulk command transfer result=0 usb-storage: Attempting to get CSW... usb-storage: command_abort() called usb-storage: -- transport indicates command was aborted usb-storage: Bulk reset requested usb_control/bulk_msg: timeout usb-storage: Bulk soft reset failed -110 usb-storage: scsi command aborted usb-storage: *** thread sleeping. usb-storage: device_reset() called usb-storage: Bulk reset requested usb_control/bulk_msg: timeout usb-storage: Bulk soft reset failed -110 usb-storage: bus_reset() called hub.c: port 1, portstatus 511, change 0, 480 Mb/s hub.c: port 1 of hub 1 not reset yet, waiting 10ms hub.c: port 1, portstatus 511, change 0, 480 Mb/s hub.c: port 1 of hub 1 not reset yet, waiting 10ms ehci_hcd 00:0c.2: port 1 high speed ehci_hcd 00:0c.2: GetStatus port 1 status 001005 POWER sig=se0 PE CONNECT hub.c: port 1, portstatus 503, change 10, 480 Mb/s ehci_hcd 00:0c.2: devpath 1 ep0out 3strikes hub.c: USB device not accepting new address (error=-71) ehci_hcd 00:0c.2: GetStatus port 1 status 001803 POWER sig=j CSC CONNECT hub.c: port 1, portstatus 501, change 1, 480 Mb/s hub.c: port 1 connection change hub.c: port 1, portstatus 501, change 1, 480 Mb/s usb.c: USB disconnect on device 00:0c.2-1 address 2 usb-storage: storage_disconnect() called usb-storage: -- releasing main URB usb-storage: -- usb_unlink_urb() returned -19 usb.c: kusbd: /sbin/hotplug remove 2 ehci_hcd 00:0c.2: free_config 1 devnum 2 hub.c: port 1, portstatus 501, change 0, 480 Mb/s hub.c: port 1, portstatus 501, change 0, 480 Mb/s hub.c: port 1, portstatus 501, change 0, 480 Mb/s hub.c: port 1, portstatus 501, change 0, 480 Mb/s hub.c: port 1, portstatus 511, change 0, 480 Mb/s hub.c: port 1 of hub 1 not reset yet, waiting 10ms hub.c: port 1, portstatus 511, change 0, 480 Mb/s hub.c: port 1 of hub 1 not reset yet, waiting 10ms ehci_hcd 00:0c.2: port 1 high speed ehci_hcd 00:0c.2: GetStatus port 1 status 001005 POWER sig=se0 PE CONNECT hub.c: port 1, portstatus 503, change 10, 480 Mb/s hub.c: new USB device 00:0c.2-1, assigned address 3 usb.c: kmalloc IF dfe6d960, numif 1 usb.c: new device strings: Mfr=73, Product=87, SerialNumber=107 usb.c: USB device number 3 default language ID 0x409 Manufacturer: Plextor Corp.
