usb chipset

From: Gary Swanson <hidden>

Hello,

I hope this isn't an inappropriate newbie question, but here goes.

We have been developing solutions using a PowerPC823, which has on chip
USB support, but we are starting another development with the PowerPC
855, which I understand doesn't have on-chip USB support.

My question is; are there external USB chipsets that we can use that are
already supported by the 2.2.14 kernel (from the MontaVista CDK 1.2), or
does anyone have any recommendations for a chipset that would make the
USB support as straightforward as possible ?

Thank you,

Gary

Hi,

I nearly have the same problem. I need USB support for an PPC405CR
platform ! As far as I know. only PCI USB chipsets (OHCI/UHCI) are
supported by linux. It is also a little problem to get usb host
controller other than PCI chips (I am not sure if you need a masteror
slave chip). But a solution seams to be at the horizont.
The USB host/slave chips from scanlogic (SL11H/S and SL811). I read that
softconnex will write some linux drivers for those chips. But I am sure,
not under the GPL. So it would be nice if someone would do that under
the GPL.
