Hi, I am having problems with the 3.6 musb kernel driver. I am running testusb.c and test.sh to try and diagnose where the problem may live. Here are the outputs from the 'unlink' and 'control' tests. Host setup: 3.6.5-rt14-deka #1 PREEMPT RT Tue Nov 27 14:23:32 EST 2012 armv7l armv7l armv7l GNU/Linux This is on a TI AM3894 platform which is equivalent to a TI8168 without the DSP. The board support isn't mainlined, but there is nothing particularly exotic about the changes. It is primarily device drivers and device driver data. Cortex-A8 platform Gadget setup: 3.2.12-rt22+ #49 PREEMPT RT Thu Jan 17 13:58:22 EST 2013 armv7l armv7l armv7l GNU/Linux Beagleboard-Xm being used as Gadget Zero.
