Re: [Usbb2k-api-help] Yealink USB Handset

[Thomas Reitmayr]

Hi Henk and Andrew,
just today I received the key codes for a P1KH from a guy as I myself do
not own this handset either. So I think that's almost all information
needed to add the P1KH to the yealink kernel module. One thing I still
have to figure out is how to update just a part of the display.
For the first steps I will use the USB logs I received and my personal
P1KH model which basically implements the device side ("hardcoded") of
USBIP. I will let you know how work progresses.
Regards,
-Thomas

PS: My current knowledge about the P1KH is packed into a test program
'p1kh' at
http://www.devbase.at/svn/view.cgi/yealink-tools/trunk/?root=experimental
and some USB log files at
http://www.devbase.at/svn/view.cgi/yealink-logs/?root=experimental
