Good day to all! My laptop has 2 usb 3.0 ports for mouse and keyboard (no more ports). In order to connect a microphone, I bought a HAMA Square1: 4 usb hub , passive, 500mA, 5V.
The microphone did not immediately extend the hub, so it is in one of the laptop connectors. But the keyboard (normal for 300 rubles) and the mouse (bloody V7 with backlight) I stuck through the hub. When surfing the Internet, everything works fine, but in the game, the mouse seems to freeze for 2 seconds and the FPS drops. Everything is fine without a hub. With what it can be connected?
Will an active hub fix the situation?
Thank you!

Any USB hub is active, because that's how the USB protocol works. You are probably talking about whether he needs external power, or he receives it from the port to which he is connected.
In any case, in order to answer your question, you need to understand what is happening with you. Look in the kernel logs, etc.

Buy a hub with external power supply from a 220 volt network. They are worth a penny.
And make sure everything works.
Or, if it does not work, then the problem was not in the hub.
IMHO, a mouse and a backlit keyboard is quite a lot for a hub without power, it's even surprising that it somehow works for you.
Here, recently on the Toaster, a person complained that only the backlit keyboard on the laptop does not work for him, but only works on the desktop. And she earned only with a hub with external power. That means you're in luck.
PS:
Sometimes a laptop / motherboard comes with additional software that can turn on the supply of additional (enhanced power) to USB. As if "for charging mobile devices", but in fact your case is suitable for this.
If it is the picture that freezes, as you write "FPS drawdown", then the mouse is out of business here.
This is either a network lag (if a network game) or a video card / processor / disk does not pull (exactly in the same order as I listed, that is, most likely the video card).
Another option is friezes due to overheating of the system, when there is not enough cooling and the automation makes HALT to the hardware so that fatal overheating does not occur. But this is less likely.

If the hub does not pull the power of the devices, then short-term dumps of devices may occur.
At the moment of dumping and connecting back, short friezes of the system may occur.
If it's still possible, then hand over the hub back and take another one.
