Comment on Why do (desktop) PC have so few USB ports ?
jkrtn@lemmy.ml 11 months agoYeah, the spec is only 1A or something, if you try to share that with 5 devices that all need 250mA it just isn’t going to work.

Do you know how motherboards split up this 1amp spec? Does each USB port on a motherboard have 1amp, or do they often end up sharing?

To be compliant with standards, USB ports directly on the motherboard must supply at least 500mA each for USB 2 or 900mA each for USB 3.
They can supply more, but that’s the minimum that should be expected.
