You can not "poll the USB data lines", that does not work at all, please go read the USB spec at www.usb.org for why that is so. You need to write a USB driver on the device side (and probably the host side as well) to send/receive such a command. best of luck, greg k-h -- unsubscribe: android-kernel+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-kernel
