Connect Volumio Primo to PC through USB

Hi, I would like to stream audio from my Volumio Primo to a PC to do some DSP there, then connect the PC output to a multichannel DAC. Normally you connect the Primo to a client via a USB A to USB B cable but I haven’t seen any PC with a USB B input yet.
Is there a way to do what I want?

thanks,

Jan Didden
