Left hand USB port not recognising all devices

Hi, I have a MacBook Pro that I bought in November.
I've noticed in the last few days that USB devices connected to the port on the left hand side (i.e. next to power socket) are not always being recognised. So, for example, it sees my iPod and Mighty Mouse, but not my Nikon camera.
What could be causing this? Should I be worried?

The dealer is correct in that Apple provide the same specs for each usb port - 500mA. However experience has shown that most often there is a difference between the ports. Apparently there is virtually no margin above the 500mA on MBP's. There may be some other circuitry difference causing the lesser performance from the LH port. It probably doesn't need much to make the difference with plugins close to the 500mA max.
For my optical Logitech mouse the difference seems to be that the mouse must be used on the same side of the computer as the usb module to work reliably though it doesn't matter which port if I'm happy to use it & the module on the LH side of the computer. This is not a problem with the MBP in this instance.
My WD My Book Essentials external drive works fine on the LH side port.
I have not yet seen anywhere any objective test of the power output from the 2 ports. I would be interested in the results.

Re Issue with Left Hand USB Ports on my Elitebook 8560w Workstation

Hi There..
I am looking for advise on my 8560w Elitebook station runing fine on windows 7 32bit ?
My issue is I have lost all power to the three left hand USB ports ? I have not been able to check if the display ports works as I dont own a cable.
The right hand USB ports work fine !
Does anybody have any ideas please ?
Best regards
James

Hey James,
It is possible that the section of the motherboard has failed. Does anything else on that side of the laptop work properly? Have you tried using multiple devices on those ports? I would first make sure its more then one device that does not work on that side. I would then go ahead and check to make sure your BIOS is up-to-date. There was a new BIO released this year. Here is the link that will walk you through how to update the BIOS and the link to download it: HP EliteBook 8560w Mobile Workstation
Hope this helps!

USB Port not recognising (MBP Late 2011)

USB Port not recognising iPhone or External Hard Drives. But working with Flash Drives!! (Both not working) (MBP Late 2011)
MBP Late 2011
OSX 10.8.3
2.2GHz Intel Core i7
8GB 1333MHz DDR3

Yes, Box is checked. I've used many hard drives on my laptop both through firewire and USB I own about 4 hard drives through all different sizes and none of them work (started to happen about a week ago)
iPhone:
No nothing happens when my iPhone is plugged in. No charging, not syncing, iTunes doesn't recongise anything is there and my dropbox account which downloads the photos doesn't see its there, iPhoto and Aperture don't see my phone.
However My Girlfriend has a Macbook (white 2009) I plug everything into her laptop and everything works, chargers and reads. so its not the perferials or cables.
I know how to use Macs and PC very well and I have tried resetting and turning it back on whilst holding
Command>Option>P+R
and un plugged the charger shut it down, plug it back in and turn it on again. but nothing works...

Late 2011 MacBook Pro; one USB port not recognising anything

Hi,
I've had my MacBook Pro since January 2012, so I believe it is the late 2011 13" model. I'm currently running OSX 10.9 although the problem I've been having has been going on around 3 or 4 months, I think I had OSX 10.7 installed when the problem started.
One of the USB ports on my Mac (the one on the left when looking at them face on) is not recognising my external hard drives, or recognising/charging my iPhone when plugged into the USB. The other USB slot works fine and recognises external hard drives, however when I insert the hard drive into the faulty USB input, although the hard drive lights up and starts whirring as if it is ready to start functioning, it does not appear under the 'Devices' tab of the Finder screen, but does appear and function when using the other port.
Similarly, when I plug my iPhone 5 into the faulty port it is not recognised/does not start charging, however if I leave it running and come back later I often have at least a level of increased battery life which suggests that it does intermittently charge from time to time, and again it functions normally when using the fully functional port.
I've tried the NVRAM reset as I have read in another post but to no avail. Is this likely to be a mechanical fault over a software problem, and if so what could be wrong with it?
Thanks for the help in advance.

thank you shootist, at least now I know the problem is as serious as I dreaded, but will not loose hope waiting for a miracle and the port works again

HP G4-2275dx left two usb ports not working after OS install.

Hi all.
I had to remove my windows 8(Upgraded to Pro before) install due to compatibility with certain programs and I was not very satisfied with the results.
So I had an extra cd key for windows 7 x64 home premium.
Everything went smooth.
I had all my drivers installed.
I installed Direct X also.
But when I tried to use my tutle beach headset it would not install the driver for the headset or even make the sound when a device is mounted.
So I checked device manager and I saw three yellow excelemation errors.
two were "Universal Serial Bus(USB) controller"
one was "SM bus controller"
I have installed the catalyst drivers multiple times but no dice.
Any help will be appreciated.
Happy Holidays.

HT6437 My itunes cannot locate my ipod. All the sync option are grayed out and diagnostics says that itunes cannot find usb ports and that no device is connected when it is. What should I do to solve this issue?

So itunes is giving me problems. Since around Christmas time, itunes decided to stop reading my ipod. I connect it to my computer with the usb cable and my computer will recognize that a device is connected but itunes will not. If I go to file->devices and try to sync, all of my sync options are grayed out, while before it would just automatically sync.
When I run diagnostics it tells me that under ports that it cannot find usb ports (it has a green circle?), a type of cable isn't found, and that no device is connected with the usb cable (which my ipod is). I have been trying to fix this issue but nothing is working. I've tried restarting my ipod, itunes, and my computer, i've also tried resetting my ipod and uninstalling itunes then reinstalling itunes but nothing seems to be working.
Does anyone know how to solve this issue?

Do the USB ports work for other devices?
Does the iPod charge?
See
iOS: Device not recognized in iTunes for Windows
- I would start with
Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
However, after your remove the Apple software components also remove the iCloud Control Panel via Windows Programs and Features app in the Window Control Panel. Then reinstall all the Apple software components
- Then do the other actions of:
iOS: Device not recognized in iTunes for Windows
paying special attention to item #5
- New cable and different USB port
- Run this and see if the results help with determine the cause
iTunes for Windows: Device Sync Tests

Hi,
What about if you try to install drivers from your product's page?
http://uk.msi.com/support/mb/Z97-GAMING-5.html#down-driver
And when exactly it starts to fail to work? Did you try to have OS just installed, restart it and see if it works then? Are you able to determine which driver installation causes USBs to stop working?
thank you
i just remove USB3 controller driver and work
thank you all :D

RMBP (Early 2013) BOTH Usb ports not functioning.

Hi Guys.
I have a Retina Macbook Pro 15" (Early 2013) with 10.10.2 Yosemite.
My left side USB port stopped working about 4 months ago so I've been relying on a hub and the right side USB port for awhile now. When I went to use my laptop this morning, the USB port wasn't functioning at all. I've plugged other USB devices into it and it's not being recognized at all. The devices work in other computers and there doesn't seem to be any damage to the USB port physically.
On the USB port that just stopped working, I had a USB 3.0 4 Port hub connected with a WD External HD, and a small USB Audio Interface.
I've already tried an SMC Reset, PRAM Reset, Repaired Disk and Disk Permissions. None of that worked.
I bought it about a year ago from a Best Buy and I got their 2 year plan. But before I go there, is there anything else it could be that I can do myself?
Thanks
Joe

Hi. You have done most of the things I would have said to try. In rare cases reinstalling the Operating system can fix the problem. I have one link of suggestions you could try. Other tan that taking it back to best buy seems the only option left. http://smallbusiness.chron.com/reset-usb-ports-mac-laptops-51619.html

USB Issue - Not recognizing ANY device

I am having a problem with my USB ports.
First of all, I have a IBM Thinkpad T42 - model number 2373-9XU.
I have the latest BIOS and all the latest drivers for the USB ports.
The issue just started a couple days ago. Whenever I plug in a USB device, such as my IPod or my Smartphone, it is NOT recognized by my computer. However, any device that I plug into the USB port will start charging. So, I know there is power to the USB ports.
I have uninstalled the USB drivers and reinstalled them, still having the same issue.
Also another note, I was looking through the device manager under System Devices and there was a yellow exclamation point next to "ISAPNP Read Data Port". The error code on it was "This device cannot start. (Code 10)"
Any suggestions?
PS. I have tried to reinstall the BIOS, but when I do that it says "No update is needed at this time" and won't let me install it. Is there a workaround to that?

So, I looked at the Services information on the Recover and Restore startup utility (pushing the AccessIBM button during startup) and found the following:
Service: upnphost
Name: Universal Plug and Play Device Host
Status: Stopped
(Previous Status: Running)
Startup: Manual/On-Demand)
Path: c:\windows\system32\svchost.exe
Vendor: Microsoft Corporation

Could this also have something to do with the USB ports not working properly?

HPDV6 6c04sa - HP truevision HD camea and usb ports not working

My camera is not working - there appear to be no drivers for it through the website for re-installing, and none in HP recovery and the copies of the original drivers loaded on the computer. Cyerlink you cam does not install a driver.
How am I expected to be able to re-instal a driver when there is not driver for it?
Secondly, there is no information on the camera provided in the laptop.
USB ports on the left hand side are not working.
Finally - there is a mysterious Q drive which also appears not to function.

Touchsmart TX-2 fingerprint scanner and USB ports not working

Hi everyone,
Please forgive me if this is in the wrong spot.
Just sent my laptop (Touchsmart TX-2 1015au) off for a warranty fix - told them the USB ports weren't working on Windows 7, 64 bit. It came back wiped, running on Vista 32 bit and.....with the USB ports not working.
I figured I'd try to get it working because I need my laptop for uni and can't send it back right now. So I clean installed Windows 7, 64 bit again and its still not working. Did the standard open device manager and uninstall everything under the usb tab. All that has resulted in is causing the fingerprint scanner to stop working (being told that it is not connected) and still no working USB ports.
All advice really welcome and very much appreciated!
Thanks in advance

Hi:
Should be no problem to get W7 32 bit to work on that model.
Just use all of the drivers and software from the HP Probook 450 G0 on your model except the Audio, BIOS and firmware files.
Your model uses the Intel HD graphics driver only.
The first driver you have to install is the Intel chipset installation utility and then reboot.
