I need to build a remotely controlled USB switch, that is not a USB hub, but a device that chooses one output port at a time.
The controlling part poses no problem for me, but the reliable switching is. I would like this to be USB 2.0 compatible, but this uses 480Mbit signalling rate. USB bus should have 90ohm impedance, so this is no job for 4066 or anything the like.
I was thinking to use some small relays to switch the data pairs, but will something like this be usable at such frequency?
Anyone any experience with this?
