I have a Acer C300 Tablet PC.... The problem is that i cant seem to get the wacom driver working... it is supposed to be working by a usb serial interface, and so it seems to be to. But nomatter what i try i just cant seem to get the device working.

# cat /proc/tty/drivers
/dev/tty /dev/tty 5 0 system:/dev/tty
/dev/console /dev/console 5 1 system:console
/dev/ptmx /dev/ptmx 5 2 system
/dev/vc/0 /dev/vc/0 4 0 system:vtmaster
usbserial /dev/ttyUSB 188 0-254 serial
serial /dev/ttyS 4 64-71 serial
pty_slave /dev/pts 136 0-1048575 pty:slave
pty_master /dev/ptm 128 0-1048575 pty:master
pty_slave /dev/tty 3 0-255 paty:slave
paty_master /dev/paty 2 0-255 paty:master
unknown /dev/tty 4 1-63 console

So it seems to be registerd but it is non existing in /dev....

Any ideas anyone? Help is much appreciated.

Regards Kim

/dev/ttyUSB* devices are remapped by udev into /dev/tts/USB*, so check if you have a /dev/tts/USB0.

Nope...
I only have /dev/tts/1-7
nothing else

Look at this link. Apparently it's a normal serial port, not USB, but it is at a non-standard address. Emerge setserial and linuxwacom if you don't have them already, and try running:

Code: Select all

setserial /dev/ttyS0 port 0x6F8 irq 6 autoconfig

Normally you should have a /dev/tts/0. Run that to test it:

Code: Select all

wacdump -f c100 /dev/tts/0

If that works, you need to edit /etc/serial.conf and put the setserial line in it (but without "setserial"). For the X configuration, look at the site, but replace all occurences of /dev/ttyS0 by /dev/tts/0.

Thx. it seems i had a miss spelling the last time i did trye that

On to the next problem...

when i use the stylus it works very well until i actually trye to "click" on the screen. after clicking the first time it somehow changes the layout so when the stylus is halfway across the screen the pointer is altheway across the screen... ???

"emerge setserial"
add to /etc/conf.d/local.start: setserial /dev/ttyS0 port 0x6F8 irq 6 autoconfig

(just for reference)
