T440 blown USB port

Hi
My PC gave me message that USB overcurrent was detected. After removing USB device and restarting the PC the USB port on laptop refuses to work. No power or detection..
is this a hardware issue?

It usually means an incompatible device was plugged in and damaged the hub controller

I think I have blown out my USB ports. Plugged eternal drive to USB port; drive also had an AC plug which I plugged in. Screen went white; unplugged external drive (both USB and AC plug). Restarted MAC Pro. Everything came back except USB ports

I think I have blown out my USB ports. Plugged in an external drive to USB, but drive also had an AC connection which I connected. Whole screen went white; unplugged external drive (both AC and USB) and shut down MacPro. Restarted and everything came back except access to USB ports. Have tried to reset PRAM and SMC. No success. Have I blown out the electronic circuitry to my USB ports?

Thanks for the response, but ironically enough, I feel really stupid after posting that because a couple minutes after posting that my DELL mouse started working again, but I honestly don't know how long that'll last. After it started working again, I tried switch which port it's plugged into again, and the other one (the one closest to me) still isn't working. If it stops working again (which it probably will), I'll definitely take it to the Apple Store. But, for some reason almost every time I take a device to the Apple Store, it fixes the problem itself when I get there, and then stops working after I leave (like just now.)
That's happened a couple times, like when my computer was heating up alot, and when my phone's sound kept shutting off by itelf.
Anyways, I want to keep this discussion up just because I know it'll stop working soon. But, yeah, I was planning on taking it to the Apple Store anyways, but I think the earliest I can is probably Saturday or Sunday, so I'll do that then.
Thanks for the response!

Display USB ports blown, please please help!

Please try and offer some type of suggestion....
i got a second Apple Cinema display the other day. The white, plastic kind.
so, now i have two. yay!
except when i plugged in the new/ second display into my powermac G5, it immediatley put the cpu to sleep...hmmm
woke it up, and the display was working fine.
except the USB ports didn't work anymore...
i needed the USB ports though for my mouse and keyboard. so, i plug my original apple cinema display in again, works great
except ....the USB ports on that display are now not working either!!
ARRRGHHH
So, this free new display either..
- blew out the usb ports on TWO displays, which makes no sense.
- plugging in the second display changed a setting in the Mac that allows the USB ports on the display to work....
no clue
i've restarted
unpluged and replugged both displays
click 'detect display'
no effect
Please try and offer me a suggestion on this!
otherwise I guess it's off to the shop to get a USB hub (the usb ports on my Powermac still work fine)

USB port possibly blown???

Hey Guys,
Here is my situation:
First of all I am a drummer and I use my PB in live shows to run our backing tracks.Last night we were rehearsing for a show this friday and I went to plug the PB into a DI box to get it patched into the PA system and the sound guy where we practicing had no clue as to what he was doing and had the channel unmuted and the gain wide open.Well needless to say it made a insane noise and I immediately unplugged the PB.
I was using one of those Turtle Beach USB to audio adapters because my sound out is bad(another story in itself) and it immediatly would not power back up and I could smell it had burned inside.Then this morning I tried to use that usb port and it is dead.
I am not sure if it is fried or what but I thought I would see if you guys had any input as to if it would be an expensive fix through apple.
So this is so long but thanx for reading if you did.
Later

G530 USB Port Problem

My USB ports will not recognize any individual USB device. Either get a device fail message or no message at all. 'Drive active' lights do not come on at all on flash drives, the laser does operate on any optical mouse, but none of the buttons or wheel will work and no cursor movement.
WILL recognize any and all devices if I use an externally powered hub. Have a self powered hub but it also is not recognized.
I'm somewhat technically literate but not on the intricacies of the internal workings of a computer. Could I have blown out the power circuit for the ports?
Solved!
Go to Solution.

you must have too many things plugged in to the USB. The laptop only has so many amps it has to split with all the slots. So if you have a lot plugged in they all will not load. That's why they work with the powered USB hub. (it's not using the laptop power) Now if you are getting this with only plugging in 1 thing then you may have a hardware issue if your laptop is plugged into the wall. Also you may want to check to make sure your laptop is at least on the balanced setting.

Usb port available amp

I have an HP Envy m6-k025dx. What is the avail amps from each USB port, 2.0, 3.0, and the charging 3.0?
Does the same DC power supply power all three ports?
I am asking because I have an Un-powered port expander . ON my previous HP laptop the USB port's power was blown because I had too many things plugged in, ( from 2005)
I could not find any USB power avail amp specs in the user manual.
Thank You

When booted in 10.4.x launch Activity Monitor and see if anything "Epson" related, is in the list. (Applications-Utilities folder)
BTW- Command-1 (one) will Show Activity Monitor as a Text-List view or just go to the Monitors Menu and click on it.
If there is a Epson(process?).app running it may have the printer already tied up and may not let Chooser stake a claim to it because it sees the USB port busy. It may work after you quit or force quit anything related to your printer.
Don't forget that the printer may need a 30 second power off / reset anytime there some print bug. This is the most common issue with printers.

My USB port (closest to the screen) is not working? And what is an IR Receiver in my USB port?

Hi everyone,
     I recently found out that my USB port, closest to my screen, is not working. Before I called Apple Care for help, I performed a PRAM and a SMC RESET, which unfortunately did not work. I called Apple Care and they help me troubleshoot simple resets such as, shutdowns and restarts. The representative I spoke with conluded that the physical hardware has an issue and must be brought to the Apple Store for a diagnosis. I called the Apple Store to at least budget the fee for getting a USB port fixed and it's about $300.00. I never dropped my macbook or had any sort tactile encounterment with hard surfaces by dropping or hitting. I don't understand how my macbook pro would be physically damaged. I then thought maybe my software was out of date (right now I am running 10.9 Mavericks) or I forgot to do the minor software updates, but I was at a lost again because my macbook is up-to-date. I searched for further help and found a way to monitor what's plugged into my usb ports. (I read in the apple forums that a girl had nothing in her usb ports, but upon looking at the System Information> Hardware> USB, that the macbook recognizes that there are drives in the ports) I looked at my ports; one is being used by wirless mouse (the port that works) and the other (the port that doesnt work) is being used by an "IR RECEIVER". Now, is the IR Receiver actually using that port and that's why my macbook cannot recognize other devices inserted into that port? Or is the IR RECEIVER suppose to be in that port and that the hardware for that port is simply damaged (which would mean I need $300.00 to get that fixed)? I know this is a lot, but someone help me?

I can help with the "IR Receiver" part of your question. That's the piece of hardware inside older MacBook Pros (MBPs) that lets them work with the Apple Remote. "IR" is the standard abbreviation for "infrared," the portion of the electromagnetic spectrum used by remotes for many common devices (stereos, cable boxes, Apple TVs, etc.). The remote sends a coded stream of IR pulses; a corresponding receiver in the target device "sees" the infrared light and decodes it. The MBP's internal IR Receiver sends the received signals to the processor via USB through an internal hub.
The most recent MacBook Pros have dropped the IR receiver and no longer work with the Apple Remote.

Syncing music with USB port 1.1

I just got an iPod classic 160GB, but it doesn't communicate with my computer properly.
I tried to put some songs to the new iPod, but after syncing 20 songs I got the error message "Attempting to copy to the disk "(iPod name)" failed. The disk could not be read from or written to."
I called AppleCare to solve the problem, and the guy told me that I need to upgrade the USB port from 1.1 to 2.0.
Does anybody know if I really need to upgrade my USB port to 2.0?
I read some of the topics on this discussion page and some people were saying that the USB 1.1 works with iPod classics.
I also want to know if any of the transfer cables which convert FireWire to USB2.0 works with iPods.
I don't want to spend any more money to upgrade my computer to make it work with my iPod.
(I had to upgrade OS)
Please help me to get my iPod work!!

The USB port on your Cinema is a port on the built-in hub in the display. It can't supply the power needed by the iPhone.

My new 8th gen iPod nano is 'not recognized' by my computer. My computer runs on Windows 7, and I've installed and updated the latest versions of itunes etc, but still to no avail! I've tried different usb ports, troubleshooting...

My computer runs on Windows 7, and I've installed and updated the latest versions of itunes etc, but still to no avail! I've tried different usb ports, troubleshooting, etc... But it still says "One of the USB decuces arrached to this omputer has malfunctioned and windows does not recognize it".
The iPod is brand new, sent to me by Apple as part of the 1st gen replacement programme. I've been using the cable that came with the 1st gen iPod (I bought the first gen second hand) It always worked on my computer with the 1st gen iPod. So I was wondering, do you think I need to replace my cable in order for my PC to recognize my iPod or is it something else?
Thanks

Try a different cable. And are you connecting directly to your computer or through a USB hub?

IPod is not recognized by my computer's usb port and itunes

Remove my ipod from the computer without ejecting it and now the ipod want turn on, it is not being recognized by my computer's usb port or itune. I have reinstalled itune and still have the same problems.

1. Update iTunes to the latest version. Plug in your iPod. If iTunes still can't recognize it, then in iTunes in the top left corner click help> run diagnostics. On the box that comes up, check the last two things. Click next and it should identify your iPod.
2. Click on your windows start menu. Type in "services". Click on it and when it pops up, on the bottom of it click on "standard". Now Scroll down to find "Apple Mobile Device" Right click it when you see it and click on "Start". When it has started, close iTunes and replug in your iPod and it should show up.
3. Check the USB cable
4. Verify that Apple Mobile Device Support is installed
5. Restart the Apple Mobile Device Service and verify that the Apple Mobile Device USB Driver is installed.
6. If you just want to add some photos, songs and movies from computer to your devices, you can use an iTunes alternative to do the job.
7. Check for third-party software conflicts.

Non grounded HP Laptop have electrical feeling on usb ports

I am living here in the Philippines now and have brought my Hp laptop dv9000. Whenever I turn on the laptop with the AC I get this electrical feeling in the usb ports. When I run with the battery I feel no electricity. Since the AC can take a 100-240V input, the outlets here in the Philippines are 240V, it shouldnt have any problems. But the charger has a 3rd prong that is used as a ground, but the wall outlet only has 2.
To better understand by setup: 1. the electrical outlet has 2 prongs that lets out 240V, 2. I have and AVR (automatic voltage regulator) so I can lower the voltage for my, 3. UPS (uninterrupted power supply) that only takes in 110V. I plug in my AC charger to the UPS to power my computer.
So my question is what can I do now to stop the the electricity coming out of the usb ports? Do I need to install a grounded socket?

Have you tried restarting the laptop? Many times we get simply put the machine to sleep or hibernate- a full shutdown/restart can help with usb problems.
You might also try disabling "USB Selective suspend" in your Power Options plan.

How do I get rid of error code 2001/2006? My phone is in recovery mode. I have tried several different cords, all USB ports, my macbook, and a friends PC. This is the second time my phone has done this, the first time it was an easy fix.

I have an iPhone 4. It is in great condition, always protected. A couple months ago, it randomly went black and wouldn't turn on. I put it in recovery mode, plugged it in to my MacBook Pro and would get error code 2001 then I'd get error code 2006. I read some different forums and many people said to try using a different USB port and different cords. The last cord I tried, worked and my phone was back. Last night, my phone did the same exact thing. So I used the same method I used last time, however nothing has worked. I tried plugging it in to a PC and that didn't work either. This seems like a hopeless problem that's going to continue to happen. Any advice?

Soooooooo.... You obviously need to restore the device
It seems that you have tried several options to restore it. What I would do is leave it plugged it and hold down the Home button AND the Power button together till you see the white apple appears. Then let go of the Power button but continue to hold the home button. You should get the message in iTunes again saying that the iPhone needs to be restored. Hit OK then RESTORE.
Hope this helps!!

Problems with USB port and song transferring;

Hi! I just got an iPod and I am having problems with it. My computer doesn't have a Hi-Speed USB port, even if it's 9 months old. Some of my friends don't have it either but they still are able to transfer songs onto their iPod. For mine, it keeps saying "Do Not Disconnect." I waited for 5 hours last time I got it and it still isn't working.
I also updated my iPod software today and the iPod icon isn't appearing on the bar to the left in iTunes. I'd really appreciate any help on this! As well as if I really need to do something about the ports or if it could function like this normally.

IPhone 6 won't play with Kenwood stereo USB port. Help !!

I have a Kenwood KDC-BT743U Stereo in my car, which has a front panel USB port. I've been able to connect my iPhone 4S and play music from my iTunes catalog as well as stream music from Pandora, Soundcloud, Tune In Radio, Mixcloud et al, without any problems until yesterday.....
Now that I've upgraded my phone to a iPhone 6 and when I connect it to the stereo via the USB port, it doesnt play at all. After about 2 minutes of trying to connect , I recieve a 'USB Error" . As I stated, I've had no problems with my iPhone 4S, which I've used with this same stereo deck for the last two years without any problem what so ever.
I'm looking for some guidance on next steps to take in order to fix the problem? Did Apple change the spec in some sort of way? Do I need to go to Kenwood for a firmware update (their website provides no information about iPhone 6 compatability with any of their stereo's which is very odd to me) ?
Please help, my life in the car during long commutes is just not the same......

Possible Solution:
1. Go to Settings > General
2. Go to Restrictions
3. Enter Passcode (possibly x2)
4. Enable Restrictions
5 Disallow CarPlay
6. Reset Network Settings (Not 100% sure if this step is needed)
7. Have at least 1 song in Apple Music App
8. Have Iphone at Home Screen
9. Connect Apple Original Cable
10. That 1 Song should start playing
11. Open Prefered Streaming App and hit Play
Carplay negatively affects USB connection with Non-Carplay USB Audio Receivers.
I have the Iphone 6 with 8.3 iOS connected to Pioneer avh-41000dvd car stereo and the above solution fixed USB audio issues, including Error code 22-65.
If you are having issues upon reconnect, disconnect and bring Iphone to home screen and reconnect.

USB ports not working properly

I have a pavillion dv4 1123us - old. It is not recognizing usb devices - although the usb ports are still providing power. I have tried reinstalling the chipset and reinstalling the usb ports by deleting from device manager. Intermittently, my modem seems to fade in and out but is easy to reset - just annoying. I have tried to find a way to reinstall the bios but have been unsuccessful. Please give suggestions.

USB devices can be rather problematic as you probably already know. Thus I'd start the troubleshooting process in this situation by plugging devices (one at a time) directly into the Mac, dispensing with the hub, to see whether problems continue or not. If they do, then it means the hub is not to blame while it the problems don't recur, the hub is the culprit and would warrant being replaced.
Be aware however, that since USB is controlled by the CPU, the rate at which data streams is dependent to some degree on what else the system is doing. Thus you can help reduce issues by ensuring the system isn't busy with other tasks while you have something critical going on via USB. Or, as you discovered with MP3 playback, use firewire instead. Firewire is controlled by a dedicated controller, so performance doesn't vary with system load. That's why it is generally recommended that for situations where data needs to be streamed to or from external devices such as video cameras, hard drives, DVD burners etc, these are best connected via FW rather than USB.
