ATEN KVM Switch CS1782

This is the ATEN USB 2.0 compatible 2-port DVI KVMP switch CS1782.
The AC adapter is an ATEN genuine product, but it tends to fail within less than two years due to age-related degradation causing abnormal voltage output. Therefore, I used a general-purpose 5V AC adapter with a plug conversion adapter for power.
The instruction manual has been lost, so please download it from the ATEN website.
The exterior has scratches near the USB ports on the back panel from connection, but there are no functional issues. Please refrain from purchasing if you are concerned about minor scratches, dirt, or the fact that the AC adapter is not the genuine product.
