sd.c - "Spinning up disk..." on usb-storage flash reader

[Jonathan Thorpe]

Greetings,

I recently upgraded to 2.6.3 from 2.4.25 and whilst most things work, there is a problem that I'm having with a Scanlogic/Cypress SL11R-IDE CompactFlash/SmartMedia reader.

When I run the reader with a CompactFlash card, the SCSI disk (sd.c) is attempting to "spin up" the SmartMedia socket, which does not contain media. If I were to insert a SmartMedia card, the problem goes away.

Below are some relevant logs from the kernel:

I have two of these readers, one with slightly newer firmware which does not have this problem.

Are there any checks that I can incorporate into sd.c to see if the device is removable? The 2.4.2x kernel seemed a little more robust with checking whether or not the device was removable (i.e. USB flash memory readers), perhaps a little friendlier to firmware bugs.

Any assistance would be appreciated.
