This is quite common for HID multitouch devices without proper driver support. Sometimes using the HID_MULTI_INPUT quirk helps. Check usbhid/hid-quirks.c for examples. > Full output of lsusb -vvv attached. > > Anybody with ideas as to what I'm missing, or whether that particular > device is supported? You probably noted already that the 04e7:0020 device is listed in usbhid. Unless the device claims to be win7 compliant (implying patching up hid-multitouch), going with the evtouch X driver might get you a bit on the way. Or - god forbid - the binary blob drivers... > Using kernel 2.6.38-rc2-git5 (from Fedora rawhide). The serial elo driver has not been updated since 2007...
