I just saw, that my mail from yesterday didn't go to the list with the attachment. So here once again with a link instead: http://www.stoeckner.net/linux/usbmon_and_uhci.tar.bz2 Two usbmon traces (cat u0) are in the archive: One for plugging the device in and one for starting 24bit 44100 4+2 mode and let it work for some seconds. /sys/kernel/debug/usb/uhci/0000:00:1d.0 is included as well. It was copied while the device was running in 24bit 44100 4+2 mode. -- 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
