OREI USB 3.2 Over Ethernet HDbaseT Cat6 Extender LAN Upto 330 Feet - Extends 4 Ports USB-A Signal Over LAN Ethernet - Power Over Cable for Long Distance Extension Supports All Operating System
From the OREI Store

This is basically a USB3.2 hub split into two parts separated by up to 300ft of user supplied Cat 6/7 (ethernet style) cable. [Note that it won't work on an Ethernet "network" so you need to connect the two units directly together with a single cable.] One half (the sender) has a USB-B 9pin SuperSpeed connection [you must provide your own USB cable to connect it to the host computer) and the other side (the receiver) which can be mounted up to 300 ft away, has 4x USB-A ports. Two of these USB-A ports supply 1.5 amps (7.5 watts) while the other two supply 1 amp (5 watts).

The unit is powered by a single provided 24 volt power supply with a US standard 120v plug. A nice feature is that you can plug the power supply into EITHER of the sender or receiver, and it powers the half at the other end of the cable by sending power (I suspect it uses something like Power over Ethernet) over the cable. This gives you great flexibility in powering the whole setup from wherever you have AC available.

The traditional usage for this type of extension device would be to mount a computer far away from it's peripherals (perhaps you have a podium with keyboard/mouse/document camera and video camera, but the auditorium computer is in a rack behind the stage). I'm going to be using it to control a telescope (usb ports for the main camera, guide camera, and mount control) from a remote computer.

For testing, I plugged in a 2TB SSD, a mouse, and a USB webcam. File transfers to/from the USB SSD were just as fast when connected to the USB extender as they were when plugged directly into my laptop (limited by the SSD speed on the remote drive or my laptops SSD). The video stream worked fine, and HID devices such as the mouse were recognized correctly. There were no drivers to install, it worked with my Ubuntu 24.04 laptop just fine and identifies as a USB 3.2 SuperSpeed hub.

If you can plug in a few cables, and know how to use a USB hub, you can set this guy up, nothing to configure. Each end has three indicator LED's (power, link, and USB). The power light shows if the unit is receiving power, the link light shows if the two halves are linked together, and the USB light is illuminated when the sender is attached to a host computer.

Each end comes with "L" shaped mounting brackets, but the package does NOT include a CAT6/7 cable or a USB-B 9 pin super speed cable to connect to the host computer. The devices have a heavy duty bent steel case with air hole grills, and feel very substantial and damage resistant (but they are not intended for outdoor usage or sealed).

In the AV and classroom setup market, a $280 price tag for this type of device is not uncommon, but it feels a little expensive for the home market.
