I did some retesting and right now it looks like the power switch never works with 2.6.28rc4 (not sure how I got to the conclusion earlier that it was only after reconnect) I now always get when I run sispm: usb 3-2: usbfs: interface 0 claimed by usbhid while 'sispm' sets config #1 On 2.6.27 it works. Which information do you need exactly out of /sys/bus/usb/devices? A simple find on 2.6.28rc4 is: /sys/bus/usb/devices/ /sys/bus/usb/devices/usb1 /sys/bus/usb/devices/1-0:1.0 /sys/bus/usb/devices/usb2 /sys/bus/usb/devices/2-0:1.0 /sys/bus/usb/devices/usb3 /sys/bus/usb/devices/3-0:1.0 /sys/bus/usb/devices/usb4 /sys/bus/usb/devices/4-0:1.0 /sys/bus/usb/devices/usb5 /sys/bus/usb/devices/5-0:1.0 /sys/bus/usb/devices/1-3 /sys/bus/usb/devices/1-3:1.0 /sys/bus/usb/devices/3-2 /sys/bus/usb/devices/3-2:1.0 /sys/bus/usb/devices/1-3.1 /sys/bus/usb/devices/1-3.1:1.0 /sys/bus/usb/devices/1-3.2 /sys/bus/usb/devices/1-3.2:1.0 /sys/bus/usb/devices/1-3.3 /sys/bus/usb/devices/1-3.3:1.0 /sys/bus/usb/devices/1-3.3:1.1 /sys/bus/usb/devices/1-3.4 /sys/bus/usb/devices/1-3.4:1.0 /sys/bus/usb/devices/1-5 /sys/bus/usb/devices/1-5:1.0 /sys/bus/usb/devices/1-5:1.1 /sys/bus/usb/devices/1-5:1.2 /sys/bus/usb/devices/1-5:1.3 with gembird switch connected. -Andi -- ak-VuQAYsv1563Yd54FQh9/CA@public.gmane.org -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
