MPC8360E USB Host Controller Driver

Hi All,
   I am working in MPC8360E processor board. I want the PowerQUICC II's
Pro  USB Host controller Driver. In the manual, they told that this
controller does not belong to UHCI or OHCI standard.

  I have doubt that whether Freescale has its own USB standard.

  Please give the link or patch for that driver.


Thanks,
N.Balaji

Yes, you can call it FHCI if you like. :)

The interface is stated clearly in the UM.

There is an 8360 host driver in Freescale LTIB BSP.  Please find it on
www.freescale.com, if it has been released.

I heard that on the PQII (82xx) devices the FHCI required
intervention from the core, even when there was zero traffic
on the USB.  I think this was because the core had to
continuously service a 1ms interrupt.  This generates significant
extra loading, making it worth considering using a cheap EHCI chip
instead....

Does anyone know if this is still the case with the PQII Pro (83xx)?

There are improvements on future chips with a QE.  However it is still
full-speed and need CPU intervention.  But keep in mind that USB is not
a key feature for netcomm devices which PQ is targeting.

834x has a integrated EHCI controller instead.

Could you give a direct link ? I've been browsing around the Freescale website 
for an hour, downloaded hundreds of megabytes of archives but haven't been 
able to find the MPC8360E USB Linux driver.
