Bug Description
The hid-quanta driver backported from 2.6.34 into the Lucid kernel is slightly dated and missing a bug fix needed for the driver to actually generate events (at least with my model of the touchscreen)
Actually it's slightly more complicated - the /dev/hidraw* device responds to touches, but the /dev/usb/hiddev* device does not, and udev does not create a corresponding /dev/input/event* device.
The version in 2.6.34-rc7 includes this fix (verified by installing from the mainline PPA).

Hi John,
Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http:// cdimage. ubuntu. com/releases/ . If the issue remains, please run the following command from a Terminal (Applications- >Accessories- >Terminal) . It will automatically gather and attach updated debug information to this report.
apport-collect -p linux 580305
Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https:/ /wiki.ubuntu. com/KernelMainl ineBuilds . Once you've tested the upstream kernel, please remove the 'needs- upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs- upstream- testing' text. Please let us know your results.
Thanks in advance.
