We are using Linux kernel 3.2 from the Linux-omap repository. The OTG interface is from TPS65950 PMIC. We forced the OTG to be a host controller. But it couldn't detect any devices plugged into the port. Is there anything we have to do in the kernel to initialize it or will the new Kernel take care of it automatically?
When we go back to use the old Kernel 2.6.32 on the same HW. It seems detecting the device with an error message saying:
"rejected 1 configuration due to insufficient available bus power"
Is there any way to fix this error?
The USB device used to test is a SanDisk thumb drive.
