Version of hid-quanta in Lucid kernel is broken

[John C Barstow]

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/KernelMainlineBuilds . 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.

As mentioned in the bug report, this piece of hardware works correctly with the 2.6.34 mainline, it's simply that the backport grabbed an early version of the driver which fails to produce input events.

On Ubuntu kernel (2.6.32-24-generic):
[ 9.714605] quanta-touch 0003:0408:3000.0001: hiddev96,hidraw2: USB HID v1.10 Device [Acer T230H] on usb-0000:00:06.0-2/input0

On upstream kernel (2.6.34-rc7):
[ 11.004061] quanta-touch 0003:0408:3000.0003: input,hidraw2: USB HID v1.10 Device [Acer T230H] on usb-0000:00:06.0-2/input0

On Ubuntu kernel, it seems the hid-quanta module registers a "hiddev96" input device instead of a standard "input" input device.
Nevertheless, I do not see any modification in the code between Ubuntu and upstream kernels regarding hid-quanta.c, maybe the driver for hiddev96 is missing on Ubuntu kernel.

Would it be possible to merge this commit to Ubuntu kernel ?
