KMBox B+ Pro setup guide

The KMBox B+ Pro is the USB sibling of the KMBox Net: it bridges the two computers and converts aim commands from the second PC into genuine mouse input on the gaming side. There is no network configuration — only the cabling and a driver — but the ports matter, so keep to the order below.

Setup

1) Run a cable from the KMBox's top-left port to the second PC, and a second cable from the bottom-left port to the gaming PC.

2) Install the KMBox driver on the second PC if you have not already, then restart that PC.

3) Start Fave DMA and watch the console — it should print Successfully connected to your KMBox B+. No message? Re-check both cables, restart once more, and if it still will not connect, reach us on Discord.

4) Once connected, open the Debug tab and press Test KMBox Move and Test KMBox Click. If the cursor on the gaming PC does not move or click, unplug the KMBox completely, plug it back in and hit Restart KMBox. If the tests pass, you are finished.

Common mistakes

Almost every B+ Pro problem is a cable in the wrong port or plugged into the wrong computer, so revisit step 1 before anything else. If the tests work but the aimbot does not move in-game, make sure the KMBox is selected as the input device in the Web Menu.

Considering alternatives? The KMBox Net uses a network link, MAKCU and Ferrum are the devices we stock on the hardware page, and our Teensy firmware turns a cheap Teensy 4.1 into the same kind of device.
