# 8. Windows or Mac - C1-xMP1 does not show up in the device manager or System Report

The C1-xMP1 module is a class compliant MIDI device and does not require software drivers on Windows and Mac.

The MIDI port of the MP Controller should be connected with a USB-A port if possible.

If you are connecting to a USB-A port directly (not via a USB hub) to the computer and C1-xMP1 still does not show up in the Windows Device Manager or Mac's System Report, you need to check the internal micro-USB cable that connects on the MIDI board.

<p class="callout info">The MP Controller is meant to be rack mountable and there are bridge ports mounted on the enclosure of the unit connected to each module.</p>

To get to that port, you need to unscrew the bottom cover.

Open up the bottom cover by unscrewing the bottom screws.

Disconnect the microUSB cable from the C1-xMP1 as shown below and connect it again.   
On Windows check the Device Manager

or the Mac's System Report under the USB tree.

<p class="callout info">The Mac's System Report needs to be reopened to show newly connected devices. Alternatively you can open a terminal and paste this command  
***system\_profiler SPUSBDataType | grep -i "C1-xMP1"***  
If it is connected it will print: C1-xMP1. If not, it will not print anything.  
While on the terminal pressing the up arrow on the keyboard and enter will repeat the command[![Screenshot at Aug 07 08-29-13.png](https://kb.mpmidi.com/uploads/images/gallery/2025-08/scaled-1680-/7nvgaW23UXnFDdGK-screenshot-at-aug-07-08-29-13.png)](https://kb.mpmidi.com/uploads/images/gallery/2025-08/7nvgaW23UXnFDdGK-screenshot-at-aug-07-08-29-13.png)</p>

Disconnect by pulling gently the microUSB cable and connect it again. Check the Device Manager or System Report.

If it is still not showing in the System Report or Device Manager try the next step which is to replace the bridge port with a USB data cable.

##### Bypassing the internal USB bridge Port

You can try to bypass the internal port of the C1-xMP1 and connect it directly from the MIDI board to the computer using a microUSB to USB-A **DATA** Cable like [this](https://www.amazon.de/-/en/Amazon-Basics-Micro-Cable-7T9MV4/dp/B07232M876).

<p class="callout warning">Please note that not all microUSB cables are data cables. Many are just charging cables and these will not work. Ensure you are using a data cable.</p>
