The sispm program should unbind usbhid from interface 0 before trying to set the config. I don't know why it should start showing up now. Perhaps you need to add the power switch to usbhid's blacklist. At any rate, you should be able to get it working again by unbinding usbhid manually: echo -n 2-2:1.0 >/sys/bus/usb/drivers/usbhid/unbind Alan Stern -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
