Hi all,

We are working on implementation of the USB host controller driver for the
MPC8272ADS (eval board). 

The USB Host controller on MPC8272 chip is neither UHCI nor OHCI compliant. 

We downloaded the project cpm2usb and the patches created by Mr.Mike
Rapoport from http://cpm2usb.sourceforge.net

We integrated the 'm82xx-hcd' into the 2.6.10 source with few changes to usb
data structures (usb_hcd,usb_device,usb_host_endpoint) and to struct
hc_driver. Also updated the function ''tx_err' present in m82xx-hcd.c.

The cpm2usb project isn't maintained. If possible you should upgrade to a more 
recent kernel and switch to the powerpc architecture where a new USB driver 
called fhci is available.

The MPC872ADS is supported in recent kernels so switching shouldn't be too 
difficult.

Best regards,
