[U-Boot-Users] Problems with usb storage devices on MPC5200 / TQM5200

[Martin Krause]

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:

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?
