I got my touchscreen working with the multimedia/webcamd and x11-drivers/xf86-input-evdev ports and an entry in /usr/local/etc/devd/webcamd.conf for my eGalax USB touchscreen device.=20 In webcamd.conf, you can copy the section # Generic USB input devices. notify 100 { match "system" "USB"; match "subsystem" "INTERFACE"; match "type" "ATTACH"; match "intclass" "0x03"; # # Limit HID device attach to Wacom Devices # else webcamd might attach to your keyboard # and mouse # match "vendor" "0x056a"; action "/usr/local/etc/rc.d/webcamd start $cdev $interface"; }; to a new section, changing the 'match "vendor" line to match the USB VendorID of your input device and possibly adding a 'match "product" line= : $ sudo usbconfig -d ugen1.2 dump_device_desc | grep 'id\(Vendor\|Product\= )' idVendor =3D 0x0eef idProduct =3D 0xa119 # My eGalax Touchscreen device. notify 100 { match "system" "USB"; match "subsystem" "INTERFACE"; match "type" "ATTACH"; match "intclass" "0x03"; match "vendor" "0x0eef"; match "product" "0xa119"; action "/usr/local/etc/rc.d/webcamd start $cdev $interface"; }; replacing "ugen1.2" above with your "ugen0.2" as well as the vendor and product values. --=20 Anthony Jenkins
