The 10" (not the early model I had before) is working fine now using wmt(4). I'd tested with wmt(4) before, but it failed. Interestingly xf86-input-mouse via usbhidlib did work with mouse emulation on the 7", which the 10" doesn't have, but the emulation of the device was bad and in touch mode X crashed on both displays during device init. uep(4) doesn't work at all, it is for a completely different protocol used on some older eGalax devices - obviously some with resistive touch, but not sure. Similar the egalax_ts.c in webcamd is only for the older eGalax devices. Have to see why wmt(4) doesn't like the older devices, maybe this can be fixed. -- B.Walter <bernd@bwct.de> http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm.
