USB Ports NOT WORKING? Let's Fix Them!

A very common issue on modern motherboards is that the Intel based USB ports suddenly stop working. Reasons behind it can vary, but it happens often especially if you use the motherboard on subzero cooling and you have insulated it with vaseline or similar. It can anyhow happen even in just normal daily use with only air or water cooling.
Usually the reason behind that USB ports stop working is a blown fuse after each of the USB ports. A fully working fuse will have a resistance very close to zero ohms, but a blown one can have an infinite or very high resistance. One way of fixing the issue is to replace the blown fuses completely or just shorting them so that there is no fuse at all anymore per port. A reminder however is that you should not charge any device anymore from those ports that don't have a working fuse anymore. If something goes wrong you could damage the actual device or just the port. This fix allows you to use a mouse and keyboard properly again and you can use USB keys and similar devices properly again.
On this guide video I will show you the damaged fuses and how I just short them to make the ports working again the fast and easy way. On the EVGA SR-3 DARK there are 8 Intel based USB 3.0 ports in total at the rear IO, and one USB 3.1A port connected to third party Asmedia controller. The Asmedia ports always work, they usually don't have this issue and it still works fully on this motherboard as well, having around 0.4ohm resistance across the fuse.
All of the Intel fuses are pretty much blown so we will just short them, put the heatsink back on and run the motherboard as usual. REMEMBER that you are doing this on your own responsibility so be careful if you short the fuses with liquid metal or solder!
Thanks for watching and share this video if someone else has this same issue with a modern motherboard!

I never heard a PC sound like a running car. How cool is that!

@Null_Experis 3 года назад

Back in the mid-2000s, it was actually common to use resetable fuses. In fact, I just repaired a Socket 754 motherboard that had a catastrophic fuse failure. The fuse was reduced to ashes, and the pads were nearly pulled off the board, but it was still possible to carefully clean it up and replace it with another fuse from a junk board I had, and superglue the pads and SMD fuse into place. Manufacturers could go back to them, but they cost more, don't act as fast, and when they fail, they tend to burn up.

Thanks, I think you just solved a problem I’ve had with an old PC that’s been sitting for a few years because of the exact problem. I spent hours and hours on it years ago and gave up.

@tacticalcenter8658 3 года назад

Motherboard manufacturers could fix the situation but seems like they don't care. Also why not add a new larger fuse instead of shorting it? I used to do this with laptop motherboards when I repaired them for a job.

@LuumiJuhani 3 года назад

Yeah that is not a bad idea at all. Need to order some larger fuses.

@LuumiJuhani 3 года назад

Do you have a link where to buy larger fuses instead of those?

@tacticalcenter8658 3 года назад

@@LuumiJuhani if they don't physically fit on the board there's always a way to fit them vertical, run wires or whatever. Just consider you may or may not be able to fit the heat sink or io shield thing back on. High temp glue sticks can help to make the mod stable and with isopropyl can be easily removed as it makes the glue brittle and loose its tact to what its applied to. Else it could get stuck to components and break them off the board if you try to remove it without isopropyl aka rubbing alcohol. Anyway hot glue has its downsides too. I'm just suggesting it if you are using a really unique way to fit physically larger fuses that doesn't fit in such a small place, it's not idea.

Just found your video. Arround 5 years ago I started with a Maximus VII Hero Z97 that had PCI Express failures and other small things not working right. Moved the next year to a Gigabyte G3 Gaming Z97 and everything worked for a while like a dream. But the last (3) years from now, I'm facing these issues. I mean, USB is working but behaves weird. My docks are not working via USB 3.0 anymore, and when they did, devices such as keyboard and mouse wouldn't be recognized when replugged or even after reboot. Currently, my pc's USB 2.0 ports are doing that job flawlessly. And with these issues, I mostly got the Windows warning: USB not recognized/unknown. When I did make it work with the USB 2.0 as described, I tried to make it work with my VR headset that I bought recently. The outcome is that it did work as supposed to be, even with another USB 2.0 port. Now, it doesn't work at all on nothing but the front port of the pc case. But it would be possible that it can work on another day for example.. Possibility also is if it works, SteamVR fails to recognize it so it would be a false positive end result. Hmmmmmhh.. I'm waiting for a chance to grab parts of the next generation to replace all of this piece of shit pc.

Great stuff! For years I've been using a PCI USB card on a Rampage II GENE since I blew all the ports powering a USB hub with a too high voltage power supply. Do you think it's just the fuses or the USB controller chip itself? Also would aluminium foil taped down work? As I hate soldering haha... Cheers from the UK!

Printer does not work on 2 x USB 2.0 (fuse with 22ohms) I made the bridge and everything now works . Thanksss! (name on fuse: -S ) hyphen s

@TheMarkShenouda 2 года назад

Amazing, I did a test by putting metal to bridge and it works. Question - Bypassing the fuse, will this destroy other components if another shortage happen? But why did all my USBs short. I did plug a new RGB keyboard. I feel that could have done it. Mind you my motherboard is 4th Gen Intel.

@LuumiJuhani Год назад

I have no idea why this happens so often. If you get a short it might just burn the port.

@vipingkumar Год назад

i think its a fail safe system to protect the damage to its north/south bridge chipset. Most cases the fuses getting blown bcos of high current draw.

@xDevscom_EE 2 года назад

Eww, solder bridges. Now if you have bad USB device plugged into such "repaired" board, you will fry the board, instead of killing a 0.2$ fuse. You can buy these fuses from Digikey or Mouser, nothing special.

Hello. I am not experienced with soldering, and just want to get this right. You use the soldering material on top of the fuses right? Like you put the solder on top of the small fuse brick like you show in your video? or do you take the little fuse brick off the motherboard? And i'm wondering - is the soldering material allowed to touch the motherboard circuit board, or will that cause damage?

Hi, i have a Asus Maximus VI Hero motherboard for the Intel 4th gen cpu's with usb problems. The problem i have is very odd. The onboard connectors for front usb ports not working either. All usbs are not working/partially working. I did manage to upgrade the bios, and it went fine, but and it did recognise a usb in bios at that time. But now it wont. There was usb problems before i upgraded also, thats why i did that in the first place. Its a while since i was testing this, but if i remember correctly here is how it works: USB2 ports: They ONLY work with mouse and keyboard (i think only the highest once on the IO was working) If i connect a usb2 stick to any usb2 port its not detected either in Win10 or in the bios (drivers are installed in Windows, and everything shows up fine, all hubs etc) Usb3 sticks does not work in Usb2 ports either. USB3 ports: Usb2 sticks, keyboards, mouses and other usb devices does not work, BUT Usb3 sticks DOES WORK in Windows if i remember correctly, but they are not detected in bios or on startup. I have looked everywhere but cant find any info. Im now going to check the fuses on my board. But i would love to hear yout thoughts on this.. :-) Edit: Just checked all the fuses around the usbs and they were ok :-S I dont understand this, they show up in windows as normal, but not working.. I have cleared the bios also but no luck.
