KP200 add two USB ports with current of 2A+. The reason is simple:

Some of my power-controlled devices are the USB-powered devices, webcam etc. Those devices may get into a “not connected” status and a power reset is required.

Now, I use a USB charger + a smart plug to handle it. It is cumbersome.

If USB ports are added to KP200, I can directly connect USB cable to it. It will be very neat.

As to control, it would be nice to have 4 independent controls, 2 for power outlets, 2 for USB outlets. To save cost, 2 independent controls would be good too.
