- * URB OHCI HCD (Host Controller Driver) for USB on the AT91RM9200 and PCI bus.
- *
- * Interrupt support is added. Now, it has been tested

- * IMPORTANT NOTES
- * 1 - Read doc/README.generic_usb_ohci
- * 2 - this driver is intended for use with USB Mass Storage Devices
- *     (BBB) and USB keyboard. There is NO support for Isochronous pipes!
- * 2 - when running on a PQFP208 AT91RM9200, define CONFIG_AT91C_PQFP_UHPBUG
- *     to activate workaround for bug #41 or this driver will NOT work!
