Hi, I am still debugging with the old kernel, and I am at a point wherein, if I specify any sort of delay in the musb_gadget_set_halt function in musb_gadget.c file, the enumeration is instantaneous. If not, I see a reset signaling on the USB bus, because of which my controller gets reset. I am trying to narrow down the reason for this race condition. Thanks in advance for any help, Praveen Krishnan On Mon, Jul 20, 2009 at 12:51 AM, Felipe Balbi<felipe.balbi@xxxxxxxxx> wrote: > hi, > > On Sat, Jul 18, 2009 at 02:51:13AM +0200, ext Praveen G K wrote: >> Hello all, >> >> I am using a MUSB gadget on TI OMAP3 processor to get the device into >> mass storage mode.
