Comment 35 for bug 1258837

Having issues here too, I'll second Allan in saying anything I can do to expedite a resolution for this please let me know as this is becoming a common device on Dell's business range laptops.

Running a Dell Latitude 3300 which displays the erratic pointer behavior

xinput --list --short
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ AlpsPS/2 ALPS GlidePoint id=12 [slave pointer (2)]
⎜ ↳ PS/2 Mouse id=13 [slave pointer (2)]
⎜ ↳ USB Optical Mouse id=15 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ Sleep Button id=9 [slave keyboard (3)]
↳ Laptop_Integrated_Webcam_HD id=10 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]
↳ Dell WMI hotkeys id=14 [slave keyboard (3)]

I can confirm that Marc's temp work around in #28 helps make the scrolling that bit smoother but it is not perfect and it results in miss clicks when typing.
