+### How do I emulate various USB devices on the target machine?
+
+By default this is what is set:
+```
+otg:
+    manufacturer: Pi-KVM
+    max_power: 250
+    product: Composite KVM Device
+    product_id: 260
+    serial: CAFEBABE
+    udc: ''
+    user: kvmd
+    vendor_id: 7531
+```
+
+You can change how this is displayed with the following example:
+```nano /etc/kvmd/override.yaml```
+
+```
+otg:
+    manufacturer: Corsair
