Hi John, looks like your patch 09c96980dc72 breaks usb on rk3188 / radxa-rock. I don’t get any error message and even the usb hub is detected but no attached usb device works. After reverting 09c96980dc72 (and the related patches) everything is fine again. I tested next-20160212 and v4.5-rc3. Do you have any idea how to fix that? Best regards Michael Reverted patches: 192cb07f7928e8cb09a9851e6c0f7478baa3bc6d 03b32e4c9bd1b52fcf1e4304e7a704aa0315e398 60c0288c72c980fb37ed4e48f68c9743a53b662c 25362d318371e1e271dda24995ceabb8457b3b7c 97e463886b873f62bea2293e7edf81fdb884b84f 241729baa932a69cd203dbaa81abbb8af5b77b65 43e9034904dd37db7ed87fa8f5039c561c4004cd 55e1040e424b59063da627fb580ec953f4c01de7 09c96980dc723462ed2eeacc945fed5bcb278f85 Config: https://github.com/c0d3z3r0/radxarock-firmware/blob/master/linux.config -- 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
