# Troubleshooting

## **In Case of a Mouse Bug:**

If you encounter a mouse bug, follow these steps:

* **Ensure the flashing process has been followed correctly.**
* Press **Log Enabled**. This will reboot the device.
* The device will start logging in the terminal. You can disconnect the left USB port and the mouse, keeping the 2nd PC connected.
* Connect the **left USB port** to the **main PC**, then connect the mouse. Make a ticket in the server, Press **User Logs** and submit the logs in the ticket.

The dev will review the logs and work on fixing the mouse bug.

## Disable The Log Button

Note: when you enable Main PC log button the Makcu will be set to 4mbps until disabled correctly, this means that 115k will no longer work

Please ensure that you see this correctly

## Mouse not passing AIO test?

* If your mouse does not pass the move test, restart the **AIO** then try again.

## Makcu startup issue

* When you turn on the main pc, you have to reconnect Makcu for the mouse to work.

## Mini pc blocking Makcu

There is a **chance** your mini pc is blocking Makcu from working, currently the ch340 chip on board's is blocking Makcu.

&#x20;Some **chairs** will default to ch340 over ch343, and it will block Makcu from connecting.

### How to check if you have CH340?

Open up Device Manager.

Then find Ports(COM & LPT) and open the list.

You will see USB-SERIAL "CH340" if you don't have it then your safe from this issue.

#### T**emp fix**

1. Uninstall Ch340 from Device Manager
2. Just uninstall it before opening your chair every time.

* [x] Note: this is not a permanent fix, and cannot be resolved. its not a Makcu issue, its due to the way chairs default kmbox b pro and arduino over Makcu.

## Mouse Doesn't Work.

If the mouse which you connected through Makcu doesn't work on Main PC:

* Make sure that you connected Makcu right [Makcu Board Guide](/makcu/makcu-board/makcu-board-guide.md#setting-up-makcu)
* Try to connect **USB cable** to another **port** of Main PC.
* Try to use another mouse.

## Makcu works but chair doesn't.

* Your **chair** doesn't support Makcu.
* tell your **chair** provider on how to add support. [Chair Devs](/makcu/chair-devs/adding-makcu-support.md).
