Try using a real vid/pid so you don't conflict with any other device out there (hint, you're going to have to do that anyway in the end). > idVendor 0x1234 > idProduct 0x5678 This is an existing device id for a device that is claimed by the usbtouchscreen driver. That's your problem :) NEVER use a vendor id that is not assigned to you, problems like this can easily happen if you do, like you found out. thanks, greg k-h -- 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
