Title: Use USB Easy Transfer Cable as a host to host virtual COM port
Post by: daniel_bingamon on October 30, 2018, 04:46:50 PM

So, I want to use a USB Easy Transfer Cable like a host to host virtual COM port.

Meaning that private software on one PC will access the "USB Easy Transfer Cable" and talk across it to other private software.  Both programs would use the same protocol to communicate.

Were would I begin in intercepting communications on the USB in order to talk to the device, which is probably a Profilic PL27A1 or something similar?

Is WinUSB a possible option to use or just direct USB port ?
Are VID and PID already known ?

I just found out that VID = 067b and PID = 25a1

WinUSB does look to be the answer for this and I'm starting to find a few things on it.
Thanks for the info, I'll keep checking here for additional info.
