Any USB switch fails due to issues I won't dive into. It's what they call DOA.
I strongly suggest you go back to plain analog solutions.
i have a usb headset with i mic that i need to use as the primary for taking calls. i also want to attach a second source to listen to the calls as a trainer. 2 usb headsets do not work with this setup. i was told to get a y-jack adapter but am unable to find a usb y-jack adapter.
i was wondering if it were possible to use headphones in the actual headphones port and have sound coming out of there while at the same time, having the trainee on the usb headset talking to the customer. is this possible? and if not, what do you suggest as a better solution (without buying expensive equiptment)?
