Hi,
 I am in need of a USB Host Controller device for the Freescale MPC8270 for=
 the 2.4 linux kernel (ELDK 3.1.1). On internet I found one, but this is on=
ly for version 2.6:
http://cpm2usb.sourceforge.net/

I have a few options=
:
1. backport this driver to 2.4.25 kernel. I would like to know if this=
 is feasible or not. I get the feeling that this will take a lot of time.2. upgrade my kernel to 2.6.x. This is not preferable for me since I depe=
nd on sw modules writen by external partners. If I upgrade, I really really=
 need to be sure that this driver
is stable and reliable.
3. Use an e=
xternal USB Host Controller. Can anyone advise me on which controller to ch=
oose that runs stable and reliable on the 2.4.25 kernel (ELDK 3.1.1)?
Kind regards,

The CPM2 USB host controller is definitely not reliabl= e.=20 It relies on software to prepare SOF tokens, and doesn't do much in hardwar= e. After some experimentation with the FHCI driver posted on linux-ppc by =20 Anton Vorontsov I found out that the driver would eat around 40% of my CPU= =20 time, and some SOF tokens would be incorrectly sent. The CPM3 (aka QE) shouldn't have the same SOF issue, as it prepares SOF tok= en=20 without any software intervention, but I doubt it would perform much better= =20 in term of CPU time. If you can go for an OHCI/UHCI/EHCI based controller that would be much=20 better.
