The opb_usb2_device ip core is a USB device, not a host. It will not
work for reading a thumb drive.
You want to configure your BSP as linux_v2_6 so you can get a
xparameter_ml40x.h file which will work with linux.

opb_epc is the right thing to use to get the cypress c67300 working.
I've got a driver for the c67x00 in my git tree:
http://git.secretlab.ca/git/linux-2.6-virtex.git in the virtex-c67x00 branch.
Go here for my notes on Linux on the Virtex:

All my work is targeted for 2.6. It will be difficult to get support
if you use 2.4
