Hi all,
I'm looking for a little direction from someone who may have worked with the musb-hdrc drivers. I need to use RCN's 3.8 Debian kernel, but have build my custom board with my USB Host connected to USB1 pins on the Sitara (nothing connected to USB0). Unfortunately I've been told that the 3.8 kernel only supports one of the two ports on the Sitara, no problem, what changes to the driver or pin mux or whatever do I need to make to get it look at USB1 instead of USB0. Or, maybe this is impossible (I hope not).
dmesg from 3.15 RCN kernel
