# Makcu Driver
The **SSZ.GG DMA Tool** installs the CH343 serial driver and detects your Makcu in one click — no separate driver download, no manual COM port renumbering.
Download SSZ.GG DMA Tool
{% stepper %}
{% step %}
### Open the Makcu Setup tab
Launch the **SSZ.GG DMA Tool as Administrator** and click the **Makcu Setup** tab.
{% endstep %}
{% step %}
### Plug in the Makcu
Use a **real USB-C data cable** (not charge-only) and plug into a **native USB port** on the 2nd PC.
{% hint style="warning" %}
**KVM switches and some USB docks break the CH343 serial link.** Plug the Makcu directly into a motherboard USB port if you have issues.
{% endhint %}
{% endstep %}
{% step %}
### Install the CH343 driver
In the **CH343 Serial Driver** card on the left, click:
* **Install CH343 Driver** — installs the bundled driver. Accept any Windows UAC / driver signature prompts.
* **Detect Device** — refreshes the device status
The **COM Port**, **Device**, **Baud Rate**, and **Driver** fields should populate with your Makcu details.
{% endstep %}
{% step %}
### Test movement
Click **Test Movement** in the same card. The tool opens the COM port and wiggles the cursor on the main PC to confirm the Makcu is alive and responding correctly.
{% endstep %}
{% endstepper %}
