The comments on the header reads "low performance usb device" (or something like that).
When I plug my "Guru" thumbdisk (Easydisk was the original name I found in the net). It RED LED erratically lighted and registered a lot of errors on dmesg: ohci_hcd: 2004 Feb 02 USB 1.1 'Open' Host Controller (OHCI) Driver (PCI) usb 4-1: new full speed USB device using address 2 ub: sizeof ub_scsi_cmd 60 ub_dev 940 uba: device 2 capacity nsec 50 bsize 512 uba: made changed uba: device 2 capacity nsec 50 bsize 512 uba: device 2 capacity nsec 50 bsize 512 uba:end_request: I/O error, dev uba, sector 0 Buffer I/O error on device uba, logical block 0 end_request: I/O error, dev uba, sector 2 Buffer I/O error on device uba, logical block 1 end_request: I/O error, dev uba, sector 4 Buffer I/O error on device uba, logical block 2 end_request: I/O error, dev uba, sector 6 Buffer I/O error on device uba, logical block 3 end_request: I/O error, dev uba, sector 6 Buffer I/O error on device uba, logical block 3 end_request: I/O error, dev uba, sector 4 Buffer I/O error on device uba, logical block 2 end_request: I/O error, dev uba, sector 2 Buffer I/O error on device uba, logical block 1 end_request: I/O error, dev uba, sector 0 Buffer I/O error on device uba, logical block 0 unable to read partition table uba:end_request: I/O error, dev uba, sector 2 Buffer I/O error on device uba, logical block 1 end_request: I/O error, dev uba, sector 4 Buffer I/O error on device uba, logical block 2 end_request: I/O error, dev uba, sector 6 Buffer I/O error on device uba, logical block 3 end_request: I/O error, dev uba, sector 0 Buffer I/O error on device uba, logical block 0 unable to read partition table usbcore: registered new driver ub here are the modules loaded ub uhci_hcd ehci_hcd usb-storage Hmmm... maybe the low performance driver + low performance usbdisk doesn't work on 2.6.9. Its the "ub" modules that makes the thumbdisk erratically behave.
