Works but has blue LEDs

I opted for the switchable 4 Port USB Hub, so I change my constantly active USB power Auer without the hassle of plug-pull and can turn off when not in use. The USB hub is quite well suited for this purpose.

The infected USB devices (Bluetooth stick, and radio receiver from the gamepad) also work, as usual, without errors on the hub.

Only with my bulky DVB-T stick there is (as expected) problems as this is recognized by Windows, but not found by the TV software.
On my USB memory stick everything goes almost without problems. After connecting Windows are (as well as the DVB-T stick) prompt a message that the stick would get better performance at a USB 2.0 High Speed ​​port. Noticeable slowdowns are not noticed. Only the startup does not work.

All in all, the switchable USB hub mMn a good investment. One last remains to be mentioned: The LED's that indicate the ports can glow blue instead of red.
