Hello, before I get into this issue I'd like to state that I'm a 15 year old with little to no experience with the technical side of computers. Oh, I've modded files for games and such and I know my way around my PC and OS, but not much else. Also, I'm not looking for 'send it back' or 'get it replaced' answers.
I run Windows 10 on an Acer E5-573G-74ZJ laptop. I purchased it in early January of 2016. A few months ago my mouse (a logitech g402) stopped working, and I received an error message that read 'Unknown USB Device needs more power than the port can supply', with the options 'reset', which would 'reset' the port after unplugging any USB devices, or 'close', which it told me would make the USB port stop working until I restarted the computer. Obviously, yes the problem persisted beyond resetting or restarting the PC. And yes, the same thing happened with my other ports. The mouse would sometimes work when jiggled in a certain way, or sometimes when restarting the PC multiple times, but any movement of the cord close to the USB itself caused it to stop and send the error message again. I tested my mouses functionality with my friend, who has a logitech g502. My mouse worked in his ports, and his did not work in mine. My headphones (Plantronics Rig 500HD) however, have never experienced any problems to this day with the USB ports. The problem became so persistent, common and irritating that we sent it back, about one month ago.
They identified a problem with the USB ports, replaced them, and sent it back. Relieved, I set about getting all my data from my hard drive onto the PC, that's when I plug in my mouse. And I get the SAME error message. Unbelievably frustrating after a week of waiting. However still present, the problem seemed to be less common, and happened less often. Over the last month, however, it has slowly gotten worse and worse, until now my mouse doesn't work at all. I got a powered USB hub for christmas, so that I could stop worrying about it. With its OWN power source, and yet it ALSO gets the error message. My theory is that whatever controls the ports internally has malfunctioned somehow, limiting the power the ports are able to give out, but not completely, so that devices like my mouse, with LED's and sensors requires too much power, but devices like my headphones and flash drives don't require nearly as much power from the ports. Then again, no tech experience, so I'm open to any suggestions besides, 'Send it back', 'replace it' or 'Reset the PC' which I've tried or is out of the question. Any help would be appreciated, thanks in advance.
EDIT: Just wanted to say that yes, I did factory reset my PC after it was 'repaired'
