Hello,
We have some eGalax based touchscreens that we are trying to get
working with FreeBSD 9.2, eventually in Xorg. They are PioneerPOS
TOM-M7 screens.
They appear to be the newer eGalax models that are at least somewhat
HID compliant.
I'm looking for someone who will help us out on a contract or
consulting basis to get them to work, and document it for others. We
currently use EloTouch serial units that work fine but they are no
longer readily available...
Thanks!
Brock
Here is how the device shows up in dmesg:
ugen4.3: <eGalax Inc.> at usbus4
uhid0: <eGalax Inc. USB TouchController, class 0/0, rev 1.10/1.00,
addr 3> on usbus4
uhid0: no report descriptor
The uep driver will load and attach to the device but doesn't appear
to work... I believe this may be only for the earlier non-HID models
but I'm not sure.
uep0: <eGalax Inc. USB TouchController, class 0/0, rev 1.10/1.00, addr
3> on usbus4
Here is the output from uhidd:
uhidd -mvvvvDu /dev/ugen4.3
uhidd[1517]: open /usr/local/etc/uhidd.conf failed: No such file or
directory
