I tried kernel 2.6.23.17 and there the touchscreen is recognized
using the builtin usbtouchscreen driver

/proc/bus/usb/devices delivers
T:  Bus=02 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#=  2 Spd=1.5 MxCh= 0
D:  Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
P:  Vendor=0eef ProdID=0001 Rev= 1.00
C:* #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr= 44mA
I:* If#= 0 Alt= 0 #EPs= 1 Cls=03(HID  ) Sub=00 Prot=00 Driver=usbtouchscreen
E:  Ad=81(I) Atr=03(Int.) MxPS=   8 Ivl=5ms

and

/proc/bus/input/devices
I: Bus=0003 Vendor=0eef Product=0001 Version=0100
N: Name="USB Touchscreen 0eef:0001"
P: Phys=usb-0000:00:1d.0-2/input0
S: Sysfs=/class/input/input3
U: Uniq=
H: Handlers=mouse2 event3 
B: EV=b
B: KEY=400 0 0 0 0 0 0 0 0 0 0
B: ABS=3

I also tried to blacklist the usbhid with 2.6.28.2
then it display Driver=usbtouchscreen in /proc/bus/usb/devices
but still no entry in /proc/bus/input/devices

Any ideas?
