Hi, musb should be discussed in linux-usb, but keep linux-omap as Cc. unfortunately I don't have time to help community now due to internal tasks I gotta finish, but I'm sure there's more people in linux-usb that could help you with it.

This is one problem, community can only support you with the current version of the open source kernel. Meaning you should try with linux-omap-2.6.git or linux-2.6.git. > I am facing kernel crashes when I use the converter on USB OTG port.
