USB Over Current Problem

[willzy564]

I am building a PC and after I had installed everything I started it up to install Windows 10 but it was just on a screen that said ‘USB over current detected!’ And it wouldn’t detect my keyboard or mouse either, I had not brought my Mobo onto any static electric conducting surfaces, and had wired everything correctly, I hadn’t also used the USB ports and didn’t find any jumpers bent or debris inside, the front fascia’s USB ports and the motherboard itself. I’m really worried that the motherboard is fried and really don’t want to spend anymore money that I already had. If someone can help me quickly that would be very appreciated.
I have stated my PC specs on an other thread too so go check it out if you’d like.

Have you tried disconnecting the front fascia USB ports from the motherboard?

 

[willzy564]

Yes I tried everything! I turned on outside the case, disconnected all the USB ports, slightly unscrewed the Mobo because it may have short circuited with how tight the screws were, I looked on all the forums for info and it comes up with the same stuff that I’ve already done.

I can't find your PC specs. What model is the motherboard?

The Motherboard is an ASUS H81M-PLUS, it just decided to mess up when I first turned on the built rig to install Windows 10 it shows the error.

unplug the usb headers from the motherboard. then try to boot with devices just connected to the back usb 2.x port in the back of the machine. then see if you still get the error.

then download https://www.uwe-sieber.de/usbtreeview_e.html it should tell you which port number is having a problem.
note: this is normal for a usb port created for a apple device charger if you don't have the correct motherboard USB drivers installed. (apple devices use twice the max current that is allowed so they can charge their devices faster)
(kind of a jerk move)


my last motherboard build had a usb port 9 that I could never get working correctly I just ended up disabling it.

The thing is I can’t even get into my BIOS, I don’t have Windows 10 Installed yet so I’m kind of stuck

unplug the UBS headers from the motherboard then power up to see if you can get into bios.
if not then make sure none of the motherboard usb backplane connectors are touching the case frame.

if you have a volt ohm meter see if there is current flowing from the outside of the USB connector to the case
ground.

make sure your usb headers are inserted with the pin 1 matching the pin 1 of the cable.
sometimes the headers can be next to each other and can be inserted with a offset. or on a audio header by mistake
or a reset header pin by mistake. or a case cable connecter for lights and reset connected to a usb header will cause problems depending on what the switch setting is set to.

If a system reports USB overcurrent, it means that one of USB ports has developed a short from VBUS to ground, which triggers polyfuse (or more sophisticated) protection. This frequently occurs when ESD TVS diodes on ports went bad. You need to determine which port causing the issue, and inspect and remove the offending component (usually a tiny 4-6-pin chip). To determine the USB faulty port, use any bootable CD with stand-alone OS, and look for the USB configuration and other messages.
