Hi,
Anyone using cambria board patch and USB?
https://svn.openwrt.org/openwrt/trunk/target/linux/ixp4xx/patches-2.6.26/190-cambria_support.patch
or specifically linux/drivers/usb/host/ehci-ixp4xx.c?
I'm trying to get the EHCI working on a board based on the intel IXP435
development board. I enabled the platform device
with the attached patch.
Right now I'm at the point where i have " hub 1-0:1.0: 0 ports
detected".. I'm hoping someone here can give me suggestions to help
debug this. Or if anyone knows of working patches for this board.
