Public bug reported: I/O errors when trying to access IDE disk via an USB to IDE converter (sold as R-Driver II).
Scanning with lsusb and lsscsi my system detects the device and a /dev/sda is created. However the disk partitions aren't seen and I can't mount it. A simple od </dev/sda fails with I/O errors, usually immediately but sometimes after reading a few disk blocks. I also tried booting from a live 6.06 cd and I see the same errors. I've successfully accessed the same IDE disk via the converter on the same machine via windows XP and from knoppix (2.4 kernel) without issue. >From the website at http://www.usbgeek.com/prod_detail.php?prod_id=0190 the chipset is a MYSON CENTURY, CS88186 The lsusb -vv output is Bus 002 Device 004: ID 14cd:6600 Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x14cd idProduct 0x6600 bcdDevice 2.01 iManufacturer 1 Super Top iProduct 3 USB 2.0 IDE DEVICE iSerial 2 ???????3 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 32 bNumInterfaces 1 bConfigurationValue 1 iConfiguration 0 bmAttributes 0xc0 Self Powered MaxPower 0mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 2 bInterfaceClass 8 Mass Storage bInterfaceSubClass 6 SCSI bInterfaceProtocol 80 Bulk (Zip) iInterface 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0200 1x 512 bytes bInterval 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x02 EP 2 OUT bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0200 1x 512 bytes bInterval 0 Device Qualifier (for other device speed): bLength 10 bDescriptorType 6 bcdUSB 2.00 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 bNumConfigurations 1 Device Status: 0x0001 Self Powered ** Affects: Ubuntu Importance: Undecided Status: Unconfirmed -- I/O errors with USB to IDE converter https://launchpad.net/bugs/81059 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
