Linux driver is here:

drivers/input/touchscreen/usbtouchscreen.c:	{USB_DEVICE(0x0eef, 0x0001), 
.driver_info = DEVTYPE_EGALAX},
drivers/input/touchscreen/usbtouchscreen.c:	{USB_DEVICE(0x0eef, 0x0002), 
.driver_info = DEVTYPE_EGALAX},

Can you try adding:

CONFIG_TOUCHSCREEN_EGALAX=y

To:

config_input.in

diff --git a/config_input.in b/config_input.in

Before building webcamd after "make extract patch".

It might not build, but if it does, should fix support for your device.
