Hi David,

to be honest, i thought the attachment is forwarded. Seems not like

So patch is here: https://gist.github.com/monofox/b21485f060ec875c12a736a55f9f21fa#file-patch_plantronics_w720-patch
I further created and redacted a debug log file based on original code:
And video for this: http://paste.fls-wiesbaden.de/fnkdsr/ (LED must turn
off and keep off after stopping call or placing on docking station).

If i can contribute with anything more (USB packet log,...), just let me know.

As I've also a BT300 of Plantronics for travelling, i've tested it as well. There it works without a patch.
