First you need to know if its resistive or capacitive. Heres what I did

Make menuconfig on kernel... go to drivers->input devices->touchscreens
usb touchscreen driver
then check the touchscreens you'd like to support under that. I just chose 
them all.
rebuild the kernel and make sure it gets into the proper folder to make it 
into your next os build.

Next you need to determine the vendor/product stuff from your particular 
touch screen... if you can boot into the shell, you can find this out with 
dmesg, otherwise you may be able to catch it via console cable, or logcat 
on boot.

You should find something like this:
[    5.321990] usb 1-1.3: New USB device found, idVendor=0eef, idProduct=
0001
[    5.330505] usb 1-1.3: New USB device strings: Mfr=1, Product=2, 
SerialNumber=0
[    5.338836] usb 1-1.3: Product: USB TouchController
[    5.344665] usb 1-1.3: Manufacturer: eGalax Inc.
[    5.351959] input: eGalax Inc. USB TouchController as 
/devices/platform/omap/usbhs_omap/ehci-omap.0/usb1/1-1/1-1.3/1-1.3:1.0/input/input3
[    5.366119] input: eGalax Inc. USB TouchController as 
/devices/platform/omap/usbhs_omap/ehci-omap.0/usb1/1-1/1-1.3/1-1.3:1.0/input/input4

We care about the idvendor, and the idproduct highlighted in orange here. 
We need to construct a idc file so you create a text file called 
"Vendor_<vendorid>_Product_<productid>.idc so 
"Vendor_0eef_Product_0001.idc. This is where all the touch screen driver 
parameters are going to go. Mine looks like this:

touch.deviceType = touchScreen
touch.orientationAware = 1

device.internal = 1

keyboard.layout = qwerty
keyboard.characterMap = qwerty2
keyboard.orientationAware = 1
keyboard.builtIn = 1

cursor.mode = navigation
cursor.orientationAware = 1

We need to make sure in your product copy files, that this file makes it to 
/system/usr/idc folder on the resulting build. That really should be all 
there is to it.
