I just completed the USB HID framework that parses the HID descriptor and thus doesn't rely on the simplified boot protocol. I now have working drivers for both mouse and keyboard, and I'm working on a multitouch-driver for my laptop as well.

Edit: The USB touch driver also works, but I currently lack support for multitouch and width of area pressed, which the hardware supports.

Is it this?

Sorry if this looks a bit OT.

Yes, but the web site is severly out-of-date. I'm still waiting for a stable version of Open Watcom which incorporates the required RDOS fixes. Currently, I need to use the OW fork and build it from source. Most of the code can be found in the SVN-link, but it requires building Jiri Malaks fork of OW in order to work.

Edit: Alternatively, people can use this pre-built OW package which would install a working compiler for RDOS: http://rdos.net/rdos/ow-win32.exe
