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. This works for both PIO mode and CPPI41 enabled configurations, together with my cppi41 patches that I posted here: http://marc.info/?l=linux-usb&m=138063429219730&w=2 More testing is certainly appreciated.
