Solved Could my USB ports be ''burned''?

February 6, 2019 at 07:13:39
Specs: Laptop
Hi,

I’ve connected my Mobius usb cable to my laptop, in the same time my mouse was connected to the other USB port.
As soon as I connected the Mobius, my laptop switched off. I disconnected the Mobius, and restarted my laptop. Now all of the USB ports work without that one some my mouse was connected to.

Is that port burned?!!

Thank you for your help in advance.

This clearly is an interesting and puzzling problem; and one which may not be resolved - without motherboard servicing...?

But this link may at least help explain how usb ports are serviced from the motherboard:

And this article re' usb port checking - in effect checking that the port is still showing in Device Manager... As you have two flavours of USB port I would expect there to be entries for both of the respective ports;one for usb2 and one/two for usb3.

There other option is to use a usb port checker device. They are about for anything from pennies to much more. I have used one in the past it did work/confirm the ports were OK. But that's the only time ever I have used one; and then it was more an experiment to see how they work, what they indicate etc.. Where it is just now - who knows... Amazon has quite a selection of them...

Probably just dusk, tho my brother did manage to kill 3 out of 4 usb ports on one of his cheap laptops.

but yeah you can actually kill the port by well, treating your hardware badly.

in your case, perhaps dust creating a short of some sort. (either in the mobius cable or the usb port)

Hi Hasse,

The Mobius link you provided does not work, also this is unclear:

"Now all of the USB ports work without that one some my mouse was connected to"

If the usb port you used no longer works, it suggests you have shorted something out, particularly as the Laptop powered off.

Other usb ports could be affected as power is supplied to them from the same internal source.

Suggest do *NOT* use the Mobius Cable elsewhere.

Good Luck - Keep us posted.

Also blow out the offending (faulty) port with a blast of compressed air (from a can of same); and likewise the other ports as well. The faulty one may simply be clogged with dust.

Here's the correct link: https://www.rcgeeks.co.uk/mobius-mi...
It's also shown here on the Mobius website: https://www.mobius-actioncam.com/st...

You didn't say what you're connecting it to. The Mobius site has warnings about damaging the device if the wrong cable is used.

Hi again,

Thank you all for your quick answers.
My laptop has three USB ports. 2 ports on the left and one port on the right.
My mouse was connected to the right side port.
I connected the Mobius camera to one the left side ports.
As soon as I connected it, the whole laptop switched off.
After restart, those two ports on the left still working but the other one on the right (with mouse connection) stopped working.
If it was dust or something, it should burned the port that I connected the camera to (on the left side), not the other one on the right side of laptop.

In the same time, if you can open the link and see the cable that is connected to the usb, has two cables, black (-) and red (+). In the middle of cable is a connector, and if I remember right, the connector was wrong when I connected it to the laptop:

Black <-> Red
Red <-> Black

"....see the cable that is connected to the usb, has two cables, black (-) and red (+). In the middle of cable is a connector, and if I remember right, the connector was wrong when I connected it to the laptop:

Black <-> Red
Red <-> Black"
THAT certainly could be bad, especially if the device it was plugged into had any power in it or caused the hot lead to feed back to the ground on the laptop. Something, possibly a fusable link, resistor, or transistor blew. Factory repair or baby remaining ports. Use a quality powered hub when possible to protect remaining ports.
I would never recommend any cable that is not polar dependent, meaning it could not be plugged in backwards. Converter cables specific for each need should be purchased and 'magic' all purpose converter cables should be avoided.

You have to be a little bit crazy to keep you from going insane.

Hi Hasse,

Does the Mouse work in one of the lh USB Ports?.

If not *AND* Cordless
:,
a) remove and reinsert Batteries - test again

b) if still not working,
if possible check old battery voltage,
if lowish fit new Batteries - test again.

Note - Cordless Mice can cease to operate when Battery Voltage is lowish.

====

If does not work, maybe the rh usb port is ok and something in the Mouse has failed..


Good Luck - Keep us posted

Thank you for your answer.
I’ve tried my mouse in the other USB ports on the left side of my laptop and it work very well.
I’ve tried even other kinds of usbs on the damaged USB port (on the right side of my laptop) and none of them working, so it should be something wrong with the USB port.

"if I remember right, the connector was wrong when I connected it to the laptop"

If you noticed it, why didn't you correct it? And how would the plug have gotten reversed? I'm sure they're designed so that they can only connect to each other one way; it would have taken significant force to make the connection with the plugs reversed.

I don't know why the USB port the mouse was connected to would fail rather than the other one, but I doubt there's an easy fix.

Thank you for your answer.
Because I’d checked it after damage. Then I unplugged and plugged agin the contact in the middle of usb cable. And you can plug it wrong and right very easy. That’s because I don’t remember if it was connected right or wrong.
But I don’t still understand why the mouse port stopped working NOT the same port that I connected the Mobius camera to.

So... to clarify - initially the right side (where there is only one) usb port did work OK before the current problem, and the mouse worked OK; but now that port is dead?

And the two on the left side are still OK, were OK initially and still are.

The "problem" cable connection being to one of the two ports on the left side?

Presuming that there is nothing in way of dust/debris in the defective port (air blow just to double check?), then it may be the way the ports are connected to the control board/hub which services the
the three ports... It could be that the left hand side port is in someway connected such that is/was actually the most vulnerable to possible voltage problems?

Might not always be the case that port "burned" by incorrect voltage etc. would show evidence of any burning etc..; the associated volts on usb being 5volts and nor drawing/providing much by way of current - 1 to 2Amps?)

The battery that use in Mobius camera is: 3.7V 520mAh Lithium Polymer

The question is: is there any way to fix that USB port?

Occasionally I have found (it was way back in the early days of usb ports (on laptops especially) some the actual design/construction of the actual connector part - the pin/socket it self - the actual individual pins/sockets could be become slightly distorted, misshapen - for whatever reason...

Presumably the only item which has been inserted into the dead port since - and even just prior to the problem situation - is the mouse?

If possible - using a strong magnifying lens see if you can see anything physically amiss/different to what you will see when viewing the working ports?

And - and this "is" a long shot... - try inserting a shortish usb extension cable into the faulty port,and connecting the mouse that way?

As repairing the socket/port? It would mean removing the motherboard, o rat least gaining safe access to it and the ports area. Then tracing out the connector tracks and checking to see if they are intact; if the associated IC chips/modules for the onboard usb hub are showing identical outputs (volts etc.) across the two good ports - and the faulty one - or not...

It might be viable - but likely not easily done nor cheap... - to replace the onboard usb hub if it has indeed failed for that one port. Just why that port should have failed though is indeed a mystery - other than for the idea I have postulated above.

Removing soldered components on modern motherboards is not a simple process; many are dip or otherwise soldered on, and it requires a steady hand, a good eye and a deal of skill to extract an item and install a replacement. If done by a competent techie likely it won't be cheap...?

The only thing that has been inserted in that port was the mouse.
I’ve checked it, no damage, no burn sing, nothing.
I’ve even tried with extension, other kind of usb. It’s not working.
The only difference is: the damaged port (on right side) is normal usb
And
Those two ports (on the left side) are ss-usb.

Under usb in device manager (when there isn’t any usb connected to laptop) I have:

1) Intel(R) USB 3.0 eXtensible Host Controller - 1.0 (Microsoft)
2) Realtek USB 2.0 Card Reader
3) USB Composite Device
4) USB Root Hub (USB 3.0)

Have to admit I’m not sure...

I was under the impression that in device manager it expands USB entries ports installed to show how many are there? I can’t verify that on my desktop as I now run Mac OS.

If you locate and download/run Belsrc Advisor (quite safe) it will generate a complete report of everything it finds, including umber of USB ports.

The utility is free and safe to use.

Incidentally does the usb2 card reader port still work?

Ok... that means the onboard controller (for usb2) likely has a problem.

A quick google browse leaves me a little (actually a lot...) unclear as to how a laptop services both usb versions. One site seeming to suggest the usb3 controller has software to service both versions of usb, whilst others seem to imply that there will be two controllers - one for usb2 and another forusb3.

http://www.tomshardware.co.uk/answe...

The above link details the way a usb3 configured controller services usb2. Whilst it may not really be a help here, it’s a useful read nonetheless?

I’m wondering if you were to remove the usb3 drivers and then reboot, and let the system re-install them might resolve it all. However it’s possible the night shift (evening in N. America - I’m in the UK and it’spast midnight...) may come across here again advise further re’ possible driver uninstall and re-install routine. Run Belarc in the meantime and hang about a while for other input. I’m being cautious here as I ‘d hate to disable your other ports by mistake - not having a windows system to hand to test that routine on.

Check this link out re’ driver uninstall/re-install for windows 10 - presuming your OS is win-10. The routine is much the same for win-7.

mmm it would appear so. So far as I know there are no onboard fuses that "might' protect the ports.

I guess you're into an externally powered hub so as to have at least three (preferably more ports) again?

i have a seven port D-link hub - separate power supply/adapter; and it works well.
