Subject: [Bugme-new] [Bug 4461] New: USB disk not recognised


http://bugme.osdl.org/show_bug.cgi?id=4461

           Summary: USB disk not recognised
    Kernel Version: 2.6.11
            Status: NEW
          Severity: normal
             Owner: [EMAIL PROTECTED]
         Submitter: [EMAIL PROTECTED]


Distribution: Mandrake 10.1
Hardware Environment: Dell Inspirion 7500
Software Environment: kernel 2.6.11
Problem Description:

I have a USB hard disk caddy which appears to be a hub in its own right. It is 
recognised as a ScanLogic USB hub, but the attached disk is never enumerated. 
The output from /var/log/messages is:
Apr  8 22:07:50 opc kernel: usb 1-1: new full speed USB device using uhci_hcd 
and address 2
Apr  8 22:07:50 opc kernel: scsi0 : SCSI emulation for USB Mass Storage devices

Apr  8 22:08:22 opc kernel: scsi: Device offlined - not ready after error

The first 2 lines appear immediately, but the rest take some 20 seconds to 
appear.

The device works fine under 2.4 and Windoze.

Steps to reproduce: Attach the USB hard disk caddy.
