USB Speed Settings: Pin#1 of the DIP switch is used to select the
USB bus speed, when set to OFF, the speed is Full-speed (12Mbps),
when set to ON, the speed is limited to Low-speed (1Mbps). It
depends on what USB device you are connecting. Usually, the
keyboard and mouse need to be set at Low-speed, other
devices have to be set at Full-speed.

Enable/Disable USB Adapter: Pin#2 of the DIP switch is used to
Enable or Disable (like plugging and unplugging the USB cable).
When set to OFF (Enable), the Adapter works normally, when set
to ON (Disable), the Adapter is Disabled and is treated as if it was
disconnected from the USB host port. In some cases, you may
need to unplug the USB device from the Adapter, however, if
you are using screw-lock type USB cables, you are NOT allowed
to remove the cable unless you remove the cable screws first.
Using the DIP switch will do the same thing without removing the
USB cable, simply set the switch to ON (Disable) then set it back
to OFF (Enable).
