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

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: Bulk Command S 0x43425355 T 0x3 L 8 F 128

usb-storage: usb_stor_bulk_transfer_buf: xfer 31 bytes
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.
