Hi,
with the current U-Boot (top of tree) I'm not able to access an USB memory stick on a MPC5200 based TQM5200 board. The 'usb start' command prints some error messages:
U-Boot 1.3.0-rc3-ge31711b7 (Nov 6 2007 - 14:07:54)

In the current TQM5200 configuration the generic OHCI driver is used (CONFIG_USB_OHCI_NEW). If I switch back to the old cpu specific USB driver (CONFIG_USB_OHCI) USB seems to work properly:

Has anyone observed similar problems with the generic OHCI driver?
