Hello All,
I decided to do what Linus asked, and try out a 2.5.X kernel.
The machine boots fine with the 2.5.44-ac2 kernel I installed, however I am having some problems with USB. The usb-uhci module seems to be gone. I read Documentation/usb/uhci.txt and it appears that the uhci module has been rewritten. I assume the module named uhci-hcd.o is the replacement, but I could not find that written down anywhere. I did an insmod of this module and I can now see the hub in /proc/bus/usb/devices. I dont see any of my other USB devices in that file, even after I insmod the drivers. Does anyone know what I need to do to make this all work, preferably in a way that will let me boot into a 2.4 kernel as well?

Thanks,

Jim

The latest hotplug scripts know about the new and old names and modprobe them appropriately. Maybe that will help.

Are your devices plugged in? :)

What does the kernel log say when you plug them in?

thanks,
