Is there any way that I could use what I'll call PC-A to act like a USB device to a second PC, PC-B?
PC-A <<-- Double male USB cable --> PC-B
The result I'm looking to achieve is have various directories or images on PC-A appear as a USB drive to PC-B when connected and be able to change directories when needed and appear to PC-B like a different USB drive has been inserted. Also as an extension of my question could I achieve a similar result but emulate a USB mouse or keyboard, or forward the mouse and keyboard from PC-A to PC-B through said interface?
PC-B would be one of any number of old PCs I am testing. PC-A would ideally be a means of simplifying or somewhat automating the process.
I'm also simply curious if it can be done just because I like to try out of the box stuff anyways even if the end result isn't practical for my use-case. :P
