Greg, Sorry for not replying sooner. We're using the OMAP 3530 musb port/controller (the phy is in the tps power controller) in device mode (not OTG). The kernel we're using is 2.6.32 (from rowboat android éclair).

Any ideas on what the > problem could be? What gadget controller driver is this, and what kernel version? Have you looked at the USB packets to see if there is some odd timing issue going on here? What's the difference in them between a working and not working run? thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
