I'm trying to get the phison PS1006C multi flash card reader to work
on an embedded system. I've downloaded the patch for my 2.4.18 kernel
from http://www.fuw.edu.pl/~pliszka/linux-USB/Phison.tgz and it
applied fine. But I am unable to access any device even though they
are inserted. I'm looking for suggestions to troubleshoot this.
During boot, the kernel appears to successfully probe the chip:

I'm not sure why it attaches all these disks, this is when there are
no cards in the slot. A little later, I see the following:
Freeing unused kernel memory: 4k freed

Partition check:

That same message gets printed for each of the sda through sdh disks.
Here is what the usb bus thinks:

Any suggestions?
