Thanks, this looks great (assuming this is in fact the protocol spoken by the E7470 hardware; perhaps Allen could confirm this?). I'll have a go at rebasing this sometime soon, although it looks like this may take a fair bit of work as the patch is of the usual... questionable quality that you'd expect from a hardware vendor and on top of that the driver itself seems to have evolved significantly. > > Also try to look at dell drivers page, there could be linux package for > your laptop with drivers.

However, I'm also in touch with Dell through the usual support channel so perhaps they'll be able to provide a more up-to-date code drop. > ALPS code from Dell were open source, it was just hard to find it and > compile it on other then one kernel version.

I do wish that Dell would apply more pressure on their input device vendors to take upstream support (or open protocol documentation) seriously. It's very frustrating that we need to go through this same process with every hardware iteration. Thanks again for the reference, Pali! Cheers, - Ben
