Usb port has power but wont read macbook pro

I have a macbook pro with 2.4ghz intel core i7 mac os x version 10.7.3 and my USB ports recently stopped working. They still power drives, but are not reading any information. It's as if the devices do not communicate, though the powering function of the ports still works. Any body know what I should do about this?

This is what it says under the system profiler both when something is plugged in and not... in case that makes a difference.

USB port has power but isn't working

Hey guys,
One of my usb ports has decided to stop working properly, I'm still able to use peripherals which ONLY require power, an example being my external fan which works fine in that port.
However, I'm unable to use my mouse or any storage device in the port.
The lights(if any) on the devices will light up as normal but will not do much other than that.
I have not made any major changes since the last time the port was successfully used, it has just stopped working.
I've restarted multiple times and the issue persists.
All other usb ports work perfectly normal, no issues.
Specs:
Pavilion DV6 7029TX
Running Windows 8 Pro 64bit
All up to date with windows updates
If any other info is required please let me know.
I'd appreciate any and all help someone may provide in helping me get to the bottom of this.
Cheers.
This question was solved.

Hello -Brendan-,
I think we should try ALL the drivers. The Chipset drivers are the drivers for your motherboard and the other drivers are for the individual on-board devices. I am thinking we should do your Chipset drivers first and then your on-board drivers. Like building a house we should ensure the foundation is solid before adding the house on top. What I would like you to do is to download and install ALL the drivers from the HP Pavilion dv6-7029tx Entertainment Notebook PC Drivers page. Ensure you download and install the Chipset drivers first, after that it does not matter which order you install the drivers.
Please re-post with the results on either of the threads you have on the go. Thank you for posting on the HP Forums. Have a great day!

My usb port gives power but doesn't work

Hello,
I have a 13 inch Macbook pro and my usb ports stopped working yesterday they worked fine but today I plugged in my mouse but it didn't work.
It lights up but doesnt work, after that I tried diffrent mouses same problem they light up but no movement. Reset my smc, my pram and updated Macbook to 10.7.5 still nothing. I even tried my HTC ONE X it recharged it but didn't reconize it as a phone. Help would be much apreciated.
Thank you guys and girls in advance.
Regards,
Nigel Brown

Hi Nigel,
Is machine still under warranty? I would try a OS reinstall. But its is highly likely the I/O ports have failed. They will still supply power to peripherals that are connected which is why everything still lights, but machine will not register them. The machine would require a replacement main logic board as I/O ports are connected to it. If your machine has no external damage or liquid damage then you will be covered under warranty. Otherwise it is an expensive repair unfortunately.

Hi,
I purchased Huawei Dongle and trying to connect with my new MacBook Pro (OS- Mountain Lion) USB port 3.0 but unfortunately it does not support.
When I plugged in my macbook the power is flowing in dongle due green light blinking twice in every 3 sec but no connection found or diver shown.
Please let me know how I have to use it. I got some suggestion for USB hub 2.0 but It does not make any sense and driver installation.
So please suggest proper direction to use it and provide link to install any driver.
Thanks
Tauheed Ahmad

Yes Clinton I did same, but they were (Huawei customer support) surprised about this problem, They behave like they have no idea about USB 2.0 and 3.0 knowledge. They handsUp that reason I posted my problem in this forum.
So is there any better solution to use any mediator between these USB version handling, Please let me know.
Thanks
Tauheed

Thunderbolt display has power but no picture and no USB power

I've had my TB display working well with my Macbook for a while with no problems. This morning I started up the MacBook but the display didnt respond and the USB ports do not seem to be working. Keyboard and mouse both work when plugged directly into the MacBook but not when connected to the display. The MacBook is charging from the display so it has power, but nothing else seem to be working. Any ideas, or am I looking at taking it in to the local store for repair?
Thanks,
DB

First try 'resetting' the Display by disconnecting it from mains for about 15 minutes and then plugging it back in. I've only had the problem that you describe once and this was the 'fix' for me.

"Device connected to USB port has malfunctioned and is not recognized"

When I hooked my nano up to my computer today, the screen went black with a silver apple icon on it...it's still all lite up and on...but it won't change from that screen.
And my computer says, "Device connected to USB port has malfunctioned and is not recognized", so it won't show up in iTunes.
What do I do?? Thanks.

Hi...
Use Lion Recovery to repair the startup disk if necessary, or reinstall the Mac OS X.
he cant use his key board
You'll need to use a wired (USB) keyboard.

Why has my USB Superdrive suddenly stopped working with my MacBook Pro?

Normally I plug it in and insert a CD or DVD and it is immediately recognised, but today it took the DVD, made a 'whirring' noise for a few seconds and then stopped without being recognised.

Should I get a 2.0 or 3.0 USB external hard drive for my 2011 Macbook Pro? I need it to be compatible with the USB ports of both a PC and a Mac.

Should I get a 2.0 or 3.0 USB external hard drive for my 2011 Macbook Pro? I need it to be compatible with the USB ports of both a PC and a Mac. I was thinking of getting a Seagate becuase apparently it is compatible with both systems, but I want to know which would be a better investment.

Go to your email provider's setup page and check what the settings for the SMTP server are supposed to be. Most good providers will even have instructions on how to set up Mac Mail.

I just brought Macbook pro(without retina display) on 15 june 2013 and since then put it on 6-7 hours of charging but still my macbook pro is not 100% charged. but why? (green light is displayed on the adapter pin)

i just brought Macbook pro(without retina display) on 15 june 2013 and when i switched it on the battery was 72 % charged and now the battery is charged to 62%, i used the charger that came with it and kept it for 6-7 hours on charging but it is not charged to 100% but why? also the green light is always on when i plug the charger with my mac book pro.Please tell me the meaning of Green light on power cord lid (mac book pro not charging or charging?) and also the other light if there like amber or any other colour.

Hello Shailendras33,
Congratulations on your new MacBook Pro! Thank you for providing all the information about what is going on with the charging issue.
Firstly, I found some information on page 11 of the MacBook Pro User Guide about what each color of the LED means on the Power Adapter:
When you first connect your power adapter to your MacBook Pro, an indicator light on the
MagSafe connector starts to glow. An amber light indicates the battery is charging. A green light indicates that the battery is fully charged.
You can find the MacBook Pro User Guide here (this is not for the latest MacBook Pro, but the information about the MagSafe adapter is true for the newest model):
MacBook Pro User Guide
http://manuals.info.apple.com/en_US/macbook_pro_15inch_late_2011.pdf
It sounds like you are not getting the amber light indicating your computer is charging, and you are noticing that the battery level is depleting. I recommend resetting your System Management Controller when something like this is occurring:
Resetting the SMC on portables with a battery you should not remove on your own
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

UTube video sound works on iPhone5S but not on Macbook Pro?

UTube videos from a variety of sources works on iPhone5S but not on Macbook Pro? Thinking it has to do with recommended Flash settings on the MAC. Is there an app to resolve this inoperability on a MAC without having to make Flash active?

What format is the video? Is it .wmv? Do the DVD's have any type of protection or encryption? This information will help in finding a solution.
