I've been working on some patches that allow suspending and resuming the musb-dsps platform. This was tested for host mode only. With these patches applied, I can successfully bring an AM335x board to suspend with a USB media connected, and access it again after resume. Note that this currently only works with CONFIG_MUSB_PIO_ONLY set. The cppi41 driver needs some more love to make this work. I'll work on that next.
