> And what about merging with the existing driver?
something like this? it's compile tested only. not even tested
on an egalax screen since i don't have it around...
if this is ok, we could also merge itmtouch and mtouchusb into a
single driver.

Hi,
merging is the wonderful way. i love all in one :))
but, every vendor has their own USB Vendor ID.
How to overcome the issue?

Keep adding them to the device table? Just like other drivers that
support more than one type of device :)

Hi,
I am reading this and it looks like twin brother of touchkitusb.c
Is there any chance we can combine these together?

hi,
this is the first version of the patch from a newbie :)
add support for PANJIT TouchSet USB touchscreen device.
patch for kernel 2.6.16-rc5.
thx for anyone see this, and feel free to apply it :)
Best Regards,
