Try the egalax drivers. They did the trick for me.
I bought the new model 8 Inch Lilliput Touchscreen and having problems with the touchscreen usb driver.
I go to install the usb touch screen software and it comes up with the following message during install of the usb driver:
"Cannot Install Software Usb Device"
"An error occured during the installation of the device"
"A Service installation section in this INF is invalid"
I am running Xp Pro and I have everything else working for my car pc except this.
Any help much appreciated.
Thanks Cris your a legend mate
