Seems MUSB is also broken on OMAP3 boards, booting in OTG mode I'm not able to make it work when a pendrive is connected to the port. Forcing HOST mode I get following messages: [ 13.244567] usb 2-1: new high-speed USB device number 2 using musb-hdrc [ 13.503234] usb 2-1: device v058f p6387 is not supported [ 13.592346] usb usb2-port1: unable to enumerate USB device OTOH the OTG port as gadget works.
