[Usbb2k-api-dev] P4K development

[Steve Underwood]

Hi all,

The web page at http://memeteau.free.fr/usbb2k says Yealink contributed 
some phones. Did they contribute any documentation?

I have been playing with a P4K. The LCD works just like the P1K. The 
keyboard scanning is also similar, although I think the keys are 
different. I still need to figure out a few things, like speakerphone 
control. Any info from Yealink would obviously help in this. ;-)

This phone accepts the following USB commands

0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0A, 0x0C, 0x0F, 0x11, 
0x12, 0x80, 0x81, 0x82, 0x87, 0x88, 0x8B and 0x8E.

and complains about all others. I only know what about half of these do.

Regards,
Steve
