for the moment, I don't know what is the USB/ADB adaptor because I
don't have the wacom and the adaptor yet.
Some persons on MacBidouille.com forums want me to make a driver for
adb wacom tablet. I am going to receive a tablet and an USB-ADB adaptor
by postmail. I have ever developped drivers for USB ADSL modem, PCI TV
card and audio firewire device, but I don't know how to make a tablet
driver. So I am searching for information about it.
I am going to take a look at wacom web site to find sources.
I don't know if we can write a user space driver for HID drivers, but
if we can, it's better. Easier to write, easier to debug and it cannot
crash the system.. But I don't know if I can. That's why I ask the
question.
Have you ever write a tablet driver? Do you know if I have to declare a
IOHITablet or a IOHITabletpointer?
Must I deal with USB interface or with a USB device?
I never use a graphical tablet so I don't really know what you can do
with it. I just know that you can use it as a mouse and click with many
values if the pencil is pushed with more or less strength.
Sorry for my poor english.

Hi Cedric,
I am with Griffin Technology who developed the iMate ADB to USB
adapter. I am curious how you're planning on going about this from the
hardware end (are you using the iMate or do you have another
converter?). I can probably help to some degree or another.
Depending on how you're going about it, I would probably recommend a
kext. But I have no experience writing a user space driver, so maybe
that's possible also.
If you look through the darwin sources, you can find both ADB drivers
and USB drivers. There are also some tablet sources for developers
from the wacom web site.

Hi,
I want to develop a driver for Wacom adb tablet via usb. I just want
to know if I have to develop in the kernel (.kext) or can I make a
plug-in in user space?
If I must make a kernel driver, must I make a HID driver? Must I use
IOHITablet or IOHITabletpointer class?
Where can I find source code for tablet driver? Is there some generic
drivers in Darwin?
Thanks!
Cedric Vuillet
