hi all, i had been gaming with a keyboard plugged into a usb port extender (just a small one from amazon), a gaming mouse, and a usb mic all pluged into my gaming laptop. everything was working fine, then i tried running some usb lights through my computer as well. after a few seconds my keyboard stopped working and the lights did too. i got a message that said the usb devices had been disabled because of drawing too much power. now for some reason when i plug in the usb extender or anything else into that specific usb port it works, but my keyboard won't. i plugged my keyboard into a macbook then it all of the sudden worked, and it did when i plugged it back into my laptop. after about 30 minutes it just turned off again with the drawing too much power message. i've tried updating, running dell support assist, reinstalling my usb port and keyboard drivers, and nothing has worked. i tried plugging it back into the macbook again, and it said that it was drawing too much power from the usb port after working on the macbook before. can anyone help?

by the way, the keyboard im using is a gskill rm570, my mouse is a steelseries rival 600, and im on a dell inspiron 15 7567 gaming laptop with a i7-7700HQ.

is the USB hub (I assume the USB port extender is a hub) powered?
The laptop is limited in the amount of power it can give to each port. the total combined draw is too high. a powered hub will give each port all the power it may need, non-powered hubs will need to split the single USB power.

do you have another keyboard you could test? if another keyboard results in the same behavior it may be the ports or the controller but testing the KB is the quickest test
