They sound expensive.

Hmm, I thought I typed a reply with a link to an aliexpress USB over IP adapter but either I closed the tab and it didnt post because of a rude word about how well it worked or else some mod delted it. Not sure which so not re-posting it.

Ok, this is the single port version of the USB server I got. It has software that finds it on the LAN, and lets you connect to devices on it. The 4 port one did it on a per port basis so each PC could get one port if you wanted. It shows as a fake USB controller in devicemanager that things mostly work on.

Works is a bit of an understatement, I tried some USB audio on it, and it was breaking up bad, USB to serials on arduinos etc which is why I got it were a no go except for one usb to serial chipset which only one board used, and it was hit and miss about working most of the time. I never tried input devices over it.

Never tried with a logitech dongle and not sure I could find either the 4 port or the 1 port that I got to see if its any better, it had another mode for print server which showed as a lan printer port and that worked but the new printer has wifi so they went into a box somewhere.
