I've had a thorough look into /sys/dev/usb/ugen.c, and I can't see how= =20 this panic could be occurring since the patch. =46irstly, could you try a more recent version of the Speedtouch software? = The=20 =2D -current port is only for 1.1b2, and some of the USB code has changed s= ince.=20 You can download the most recent version from http://speedtouch.sf.net/.
