I have a Dell Inspiron 15 (M5030) and it has three USB ports. Two right next to each other and one closer to the front of the laptop. One day I was just using my laptop and ejected then unplugged my external hard drive.

Ever since then the two USB ports right next to each other wont work at all but the single one works perfectly fine. The two non-working ports dont recognize devices that work on the working port nor do they provide any power to any devices whatsoever.

Ive searched and searched and have tried these things: uninstalling the USB controllers in the Device Manager and restarting multiple times. Ive tried a complete system restore. Ive updated the BIOS via the Dell website.


I dont know what to do and its extremely inconvenient having only one USB port...
The USB hub i have is working but when i plug certain things in it causes other devices to freak out.

It's possible that the ports are damaged. If you short out a USB port enough times it will stop working (possibly by a fault with the hard disk you plugged in). Hopefully that isn't the problem, but that would be my opinion. Maybe somebody will be able to give you a more optimistic answer.

Thats highly unfortunate. Do you think if i bought a different USB hub I'd have less problems with devices connecting and disconnecting whenever I plug another one in?

you uninstall them and windows reinstalls them on the reboot,and usually corrects the problem

Does Windows mark them as "bad ports" then and a driver reinstall fixes?

I remember a few years back people in college were sticking things in them as a joke to short them out and restart the victims computer! After a while a lot of the USB ports had stopped working much to the annoyance of the IT dept (!).

if thoughtless dimwits deliberately shorted them out then replacement is the only cure

LOL it was a case of one person discovered the "restart" trick and then everybody thought it was funny. Probably didn't realise why it was restarting, ie to try and stop damage from electrical shorting(!)

Anyway, back to the original question. Did dai's solution work for you?

Nope it didnt work. Ive actually done that twice before except without the hidden device part. but upon reboot I did notice something strange. I took a snapshot of it.



This kinda makes sense since there are three USB ports on this computer and two of them arent working. So one of the ROOT Hubs is being detected but th eother two arent. Its looked the same for about half an hour now.
