Some USB ports not working correctly

[max 13]

I wonder if anyone can help with this. I have an Acer All in One with 4 USB 3.0 ports, 2 on the side and 2 on the back. My keyboard, which was plugged into one of the two on the back stopped working but when I  moved it to one of the side ports it was fine. Similarly, the mouse works on the side ports but not the back ones. However, I plugged my 'phone into both the back ports and it charged but didn't show up on File Explorer as it normally does.

 

I've done the following:

checked for drivers

scanned for new hardware

restarted

all to no avail.

 

Anyone with any ideas?

if there's power going to it (it charges your phone) but nothing is detected, Sounds like whatever controls the back ports could potentially have died...

What version of windows? reinstalling / resetting the USB may help, but it honestly sounds like it's faulty...

Windows 10. It went between typing one thing and then going back to Google so yes, it probably is hardware related.

 

I've done the usual things in device manager but don't want to uninstall either of the controllers as it may be the wrong one and cause the keyboard/mouse to not work. I've looked for more up to date drivers but there are none.

Sounds like you have tried what you can, other than a full reinstall...

I'm afraid it sounds like a hardware issue - could potentially even be a dry solder joint, but unlikely....

Is there a way to solve this or is it a case of taking it in for repair? Who would you recommend?

Have you checked to make sure any power saving isn't on for any USB ports?

 

In your power profile under USB. Turn any power saving off.

 

Device Manager. Right click on the USB devices and turn off any power saving. You mentioned that you have been in device manager... nothing showing as down?

 

Anything in the BIOS about disabling USB ports?

As above and try setting the bios to defaults.

 

But.. instead of an expensive repair why not use a USB hub on one of the working ports. Not as tidy but you could use a right angle adaptor/cable to tidy it up a bit.

Hi & thanks for contributing.

 

There is no power saving option for the individual ports only the controller which isn't set.

Power saving  is off in the power profile.

There is a controller in Device Manager with the following detail:

Unknown USB Device (Device Descriptor Request Failed)

Device Type: USB Controllers

Windows has stopped this device because it has reported problems. (Code 43)

A request for the USB device descriptor failed.

 

I disable this then enabled, then uninstalled and scanned for new hardware and it returned but with same message.

I'm not confident playing with the BIOS but a USB hub is certainly an option.

 

The problem seems to be not enough power going to the 2 USB ports on the back.

With Code 43 error in DeviceManager, it's going to be a hardware fault...

If you do get a hub then get a powered one so any device plugged in will then use that and not the internal power, some also have dedicated charging ports.

Something like this:

Have you ever updated the BIOS since you purchased it?

No, but when I see a message like this:

Upgrading your system BIOS incorrectly could harm your Acer product. Please proceed with caution.

it tends to make me a bit wary.
 

I think I'll go the powered hub route.

 

Thanks.
