I regularly run into the frustrating task of of plugging in and out usb cables from my laptop depending on which devices I want to use.
I started looking into usb hubs but got a bit overwhelmed by the possibilities and price ranges.
I read that USB 3.0 specifies 900mA (0.9A) per port (https://superuser.com/questions/1460313/what-is-the-maximum-power-supplied-by-a-usb-3-0-port). Does this mean I can still use a passive splitter for devices that don’t add up to 0.9A (e.g. mouse, keyboard, Traktor Kontrol)? Is it possible to combine passive devices with active devices?
Are there any (non-design related) major difference between usb hubs? Or should I look into something else than usb hubs?
I am looking for a long-living and wallet-friendly solution.
Any other piece of advice or documentation is of course also welcome. Thanks!
