Worth trying: http://www.kraxel.org/cgit/qemu/log/?h=usb.80 It puts the qemu usb passthrough code upside down. All xfers will go through a bounce buffer, requests are submitted via libusbx. That should fix it. Of course there is the risk of regressions in other areas as it is all new code. Also make sure you have libusbx-devel installed, otherwise qemu will fallback to the old code which uses usbfs ioctls directly. cheers, Gerd -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
