It will be for a Logitech Wireless Presenter as the range is too far from the back of a room's control desk to the front where the speaker will be.

Thanks.

Also consider if your presenter device gets its power from the USB port, Or if it has its own power supply. As USB only uses 5V power, meaning volt drop is a killer over long cables.

You might be able to get around this by using a powered USB hub at the remote end.

It is just a Logitech Wireless Presenter with those small dongles as a receiver.

Ended up getting these for it: https://www.jaycar.co.nz/usb-rj45-extension-adaptor/p/XC4884

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.

I think you've confused yourself with my other thread about HDMI over Ethernet thread lol!

You did post an AliExpress link on that thread. :-)

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.
