Are there Hubs without a chip?

Question

Android

I have one micro USB output on my tablet for recharging.
I want to buy a radio wireless keyboard and mouse. But you need to simultaneously recharge the tablet.
Those. you need some kind of splitter where you can connect the micro Usb charging, and the transmitter itself to the keyboard and mouse.
Why am I looking without a chip --- I bought a Hub OTG Usb with three Usb moms, one micro Usb mom, and a Usb dad. But for some reason, the usual wired keyboard and mouse turn off after 5-10 minutes of operation. Now the mouse, then the keyboard, then the tablet goes to reboot.
I sin on the incompatibility of the microcircuit and the tablet. Although I don't know the exact reason.
