Hello everyone. I have a HP Compaq TC4200. A great Tablet PC from 2000’s. It does run Haiku, but I have noticed that the Wacom digitizer isn’t used. What I mean by that is when I tapped on the screen with the stylus, it did nothing. Does Haiku have drivers for it and it just requires more messing around or there aren’t any drivers as of right now?
Version: R1Beta5 32-bit
Quite likely there isn’t a ready-to-use driver. Maybe one of the existing drivers can be patched to support it.
Do you know how this digitizer is connected? Is it USB or something else? Do you see it in listusb for example? In that case, the output of listusb -v could be useful, as well as the HID reports for the device (they are stored in /tmp automatically if the USB HID driver has detected the device).
If it’s connected in some other way, the first step will be to find out how to access it. Maybe the code for Linux drivers (if they exist) can give some insight.
One additional issue that I have just seen is that Haiku doesn’t spin the CPU cooling fan on the TC4200 even when the CPU gets so hot that the keyboard is no longer touchable due to the heat
There is nothing visible on USB except the motherboard USB ports. So that digitizer is connected in some other way and will probably need a special driver. Maybe it is PS/2 or some custom protocol.
This should be handled automatically by ACPI but maybe this machine is too old and has a broken ACPI, or need some specific custom driver to spin the fans (not a great way to design things…).
It’s interesting. It works fine under Windows XP (I have a dual-boot hard drive)
