Description Matt Whitton 2008-01-10 23:51:00 UTC
Some newer tablet PCs use a different flavor of Wacom tablet using the "ISDV4" protocol. The current Wacom Kernel module does not seem to behave correctly with this device. No device nodes are generated, and no entry for the tablet can be found in /proc/bus/usb/devices. If the module is disabled, then an entry can be found here, but then it also says "Driver=(none)". Obviously in both cases no device nodes are generated, and the device does not function.

May I ask why is this a Gentoo-specific issue? Because we don't develop kernel, we are just shipping it.

Please post "lsusb -v" output for this device

Can you attach the output of dmesg?
Comment 5 Sebastian Kromp 2008-02-07 23:09:43 UTC
It seems that this tablet is totally unsupported for now and no patches exist to fix that, but Ping Cheng from the linux wacom project is aware of this and will work on it soon,  you can see it at

Thanks Sebastian. Matt, I suggest you keep an eye on the sourceforge bug, and when patches become available feel free to reopen this one (provided that it appears the patches are going upstream through the wacom project).
