Multiple devices on one USB connection
« on: April 10, 2014, 03:55:51 am »
Hi,
I an investigating a product design where I want to have 2 separate devices (with different PIDs) on a single USB connection (I don't want a composite device).
Is this possible?
If it is possible how do I define the device descriptor so that the PC enumerates both devices?
Many thanks,
TJ

You would need to make it a compound device that incorporates a hub with two attached devices.
