Linux USB 633 Keypad with lcdproc

Just wondering if anyone has had any joy getting the Keypad on a USB 633 to work using lcdproc.

lcdproc is out of CVS
current (0.5)
lcdproc-CVS-current-20040419

I've been debugging CFontz633io.c trying to read a byte from a keypress with out much luck.

Has anyone else been down this path?

Cheers

Simon

Thanks wyofreeride.

The 23: Configure Key Reporting needed to be set.

I have the keypad working with the test633 code in Linux now. When I've worked out a patch/work around to lcdproc I'll post it here.

Also, I'm trying to get the keypad working with freevo. If I need to patch lcd.py, I'll also post it.

Thanks again for the info - much appreciated

Freevo patch to LCD for the 633 keypad

I'll leave this for anyone doing some archeology
