USB Disk Support...FIXED

Wed Oct 11 20:54:05 EST 2006

For those interested, I figured out the issue.  It was an incorrect PCIX PIM setting.  Even though the comment on the PIM windows that are setup in luan.c (the board specific platform file in the kernel) says 2GB window, the actual register setting is only for a 512MB window.  I happend to have 1GB of memory in my system, and it must have been allocating an address above the 512MB.  In the Luan board, I only had 512MB, so that is why it worked there.

Maybe in the next kernel release, the comment should be fixed to match the register setting.

I have more information.  I am using a Phillips
ISP1562 USB host controller.  I ran the same kernel
config on the actual Luan board (with an ISP1563 PCI
eval board from Phillips), and the USB storage works
fine.  I compared the dmesg from both the Luan board
and our 440SP custom system, and here are the
differences:

The custom system stops at:
...
usb-storage: Command READ_CAPACITY (10 bytes)
usb-storage:  25 00 00 00 00 00 00 00 00 00

usb-storage: usb_stor_bulk_transfer_buf: xfer 13 bytes
usb-storage: command_abort called
usb-storage: usb_stor_stop_transport called
usb-storage: -- cancelling URB

It seems to fail on Attempting to get CSW...  On the
Luan board it gets passed this:

usb-storage: Command READ_CAPACITY (10 bytes)
usb-storage:  25 00 00 00 00 00 00 00 00 00

usb-storage: Status code 0; transferred 31/31
... <continues>

Could this be a noisy usb port?  The USB controller
used is the same, the only difference is that on the
custom board, the USB controller is onboard, where as
on the Luan board it is a PCI card.  U-boot is also
using practically the same board specific config file
and board file, other than the flash and DDR stuff. 
On the custom board, the card reader never ends up in
/proc/scsi/scsi, but it does on the luan board.

Thanks,
