Re: usb chipset

[Matthias Fuchs <matthias.fuchs@esd-electronics.com>]

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.
