On adapter connected directly only my USB hub, whose external power supply is then supplied the rest of my USB devices with enough power. Because basically provides these adapters only as much electricity as the computer currently connected.
That is not enough for my keyboard, mouse, sound card, mobile phone and external hard drive.
So far, I could not detect any problems with the switch. All devices are promptly switched and detected directly by the computer.
Delay in signal or failures, I also can not determine. Music is played throughout, even when it is read from the external hard drive.
Only one cable in the laptop and unplug to have and then be able to work immediately and then be able to switch to the PC by pressing a button is awesome.
Can definitely recommend this unit!
