Dead USB port running hot

I have a mid-2010 white unibody MacBook. It's been running fine, with the exception of a problem with the dashboard after the most recent firmware upgrade about a year ago. I just learned to work around it. But then Friday I got an error saying the the USB port was drawing too much power and was shut down. Sudden and random, as it had never happened before and showed up as I woke it up from screensaver mode. Nothing was plugged in. I have a Magic Trackpad and a Logitech keyboard connected via Bluetooth. Disconnecting them doesn't affect the error. I've tried rebooting and resetting PRAM & SMC. I'm trying to reinstall Lion, but I don't think it's a clean or fresh install. Has anyone encountered a USB port that dies but runs hot? The CPU seems to run a lot warmer than usual, buy about 20° F.
Any help is appreciated!

I recommend you make an appointment at an Apple genius bar and take the Mac in for a free diagnosis.

Dead usb port in airport extreme

I have been using the airport extreme for quite a while but it seems that my usb port is not working anymore since my external drive (connected via usb) was suddenly disconnected.
I don't see the drive recognized anymore in the airport extreme settings. I was trying two other drives and those were also not recognized. I'm sure that the drive are OK because I am able to connect those via usb on other laptops.
What could be wrong? When I plug in my Freecom Tough Drive the blue light of the drive is switched on for short while before it turns of without any connection to the airport. Resetting the airport didn't help as well. I have not changed the firmware or run any updates...It seems that I have to return the device or can I try some other things?
Please advice.

It is entirely possible to have a dead port. What have you done to verify? If you plug into all the other ports and the unit is recognized through Airport Utility, but not the one suspected, that's a good indication. Also plug into each port one-by-one and look for the green light to show on the port connector. If it doesn't show on the suspect port, that's more support of indicating a dead port. You can also unplug the power to the unit, then plug it back in, watching for the port light on the suspect connector to flash green along with all the others. The lack of a green light is not a certain indicator, but almost so. Probably a warranty issue.

My ipod, 4th generation, squeals and pops via the headphones when connected to my computer, by the USB, port running itunes version 10. Any idea what is wrong?

I have tried to five r's and using different usb ports. I have also cleaned the contacts recently but I still have the same annoying sounds. Any advice will be warmly received.

Does the iPod appear in iTunes on another PC or Mac running iTunes?

Dead usb port ?? MSI K8N Neo V2.0

I've got MSI K8N Neo V2.0. I discovered that one usb port is not working correctly. When I plug keyboard ( logitech cordless ), it wont work ( it wont even boot, becouse it said that keyboard is not connected ). When I plug mouse ( logitech MX510 ) then windows said that the device is malfunctioned, and it wont work too. I tried also to plug USB-Fdd, with the same result. Other usb ports works fine. I tried to updgrade bios and I set default options in bios and it didn't help. Does this mean that usb port is dead, or maybe this is software ( bios ) issue ??

is it one of the ports on the I/O pannel of the mobo? or is it an onboard one that you have to connect to an outside usb port? if its the second one, you might want to check if it is wired corectly or the connectors are not faulty.

Dead usb port

I have not used the Playbook's micro usb port since I got the rapid charger, which was before the OS2 upgrade. Today I plugged it into the regular charger (that came with the Playbook) but cannot get any indication that the unit is charging. I tried several different wall outlets, and since it was working fine the last time I used it, there is no reason to think the charger is the problem. Is there a Playbook software switch that I need to reset? Has anyone else experienced a non-functional usb port following the OS2 upgrade? The usb port is not damaged or physically broken as far as I can tell. Any thoughts or suggestions will be appreciated. Thanks,

mine wont charge via a PC if on less than 20% battery
is yours at least 20% charged?

My usb ports arent running as 2.0 highspeed ports

Hi guys im looking for some help
The Basics
hp pavilion a532x
Windows XP SP3
What the front reads about my usb ports
Built in 9 - in - 1 media card reader high speed USB 2.0 and firewire ports
The issue
when i plug in my wna3100 netgear wireless adapter it says "this divice could run faster" and it wont detect my adapter .
I was wondering if there was a driver i could download so my USB ports run as they should as 2.0's.

Just wondering if the Netgear software package was installed for this device? It might not show up because the driver is not installed.

One of my usb ports is dead, dv6-6070ee

i have purchased my laptop about 2 months ago, suddenly one of the usb ports is no longer working
the usb port is a USB2.0 , the other one is working and the USB 3.0 x 2 are working too
it doesnt work in windows not even at boot, my logitech mouse has led lights on them when its plugged in a working usb on booting and bios setup it works, when plugged in the dead usb port its no longer working, i tried 3 flash drives also failed
i tried to boot from flah drive instead of hard disk it also failed when flash drive is put in the dead port
i cant locate exactly when the problem happened, but im suspecting when i updated my bios to F.1A, which is listed i downloads section of my laptop
i reinstalled the update but its still dead
so any ideas on how to resolve the problem

Hi,
It sounds like a Hardware issue, so as you're still under warranty, you will need to contact HP and arrange to have the notebook repaired.
If you live in the US, contact HP Here.
If you are in another part of the world, start Here.
Regards,

Lost usb port in laptop

My wife attempted to update to Windows 10.It totally failed and "lost" the drivers for the usb ports so she can't use her mouse.We spent MANY hours on the phone with Microsoft while they took control of the laptop and attempted to fix it.They finally told us that they think there's some sort of virus on the drive they can't remove???? and that the laptop needs to have something done about the "partition" on the drive.They were not very clear about this, but told us to contact HP.Our warranty is expired. Considering this, if I do a reset to factory original will this correct the issue or has the virus done damage to prevent a recovery this way? Microsoft seemed to think a reset would not correct the problem.The laptop did not come with any disks. We are NOT any sort of experts on computers so we don't understand much of what they were telling us and we had problems understanding the accent of the person who was working the issue.

, Thanks for posting back. Yes in fact if it is proven to be a dead usb port the recovery will not solve the issue. The recovery is to ensure this is not due to a software conflict caused by an update or OS change. It is always the first step to ensure it is not a software issue. The next step is to pull and replace the motherboard if it is 100 percent tested and proven to be a dead port. Here is the link to HP support for repair options if you require that. See if you come up with any issues by running the BIOS hardware diagnostics first though just to see if there is any issues picked up. This link will help you with this. HP Notebook PCs - System Diagnostics (F2) This link will connect you with the correct department at HP support for repair options. Contact HP Support Thanks again for the post and have a great day.

The USB port on my 4th generation Airport Extreme does not recognize any peripheral devices whatsoever. In other words, it does not function at all. What can I do?

I have had my Airport Extreme for almost a year now. I have not been able to get it to work. It has never worked. I have tried everything in the apple manuals, my peripheral device manuals, and online help. My Airport Extreme Base Station has a completely dead USB port. The USB connector does have voltage and ground. Apparently there is no data transfer. I do not know how to test the data pinouts. I don't know if it is a software or driver problem, or if it is a hardware or wiring problem. My computer is a mid-2009 13" MacBook Pro. All of my external devices work well with the MacBook Pro. The USB functionality on the MacBook Pro has always performed without a glitch. It seems the problem with the Airport Extreme must either be a network communication problem or a hardware/hardwire problem. I bought the Airport Extreme to build a home inTRAnet network. I have a seperate 3rd party router for inTERnet. Contrary to what the manuals declare, the initial setup of my Airport Extreme requires inTERnet setup during the process. Even when the choice is made to limit the network access to LAN only, when I reach the end of the setup process, a prompts reads that the Airport Extreme may not function because I have not set it up for inTERnet with the WAN. Well, Dah... during the intial stages of the setup I told the machine to configure an inTRAnet only LAN setup. So... I went ahead and set it up for inTERnet and WAN. Either way, the USB port is not working. Then I set it up for the whole package, WAN, LAN, and everything. Still... no function out of the USB port. Any ideas?
P.S. The Ethernet works and so does the 802.11 tranceiver. The USB port is the only problem, but a major, major one for my needs. There is no peripheral functionality.

Okay so I figured it out. I inherited the Configurator already set up so I didn't realize that our former administrator was brilliant and set things up a little differently. To anyone else who finds themselves in this spot try this:
After you plug the iPad in and open Configurator instead of trying to 'Prepare' the device click 'Assign'
There should be groups of Users listed on the left hand side of the screen.
Select the group you want the ipad to be a part of, or make a new group. ***Note a group can be one person so this is a good feature for teachers to have individual app assignements for students.
After you select the user group click the little plus ( + ) button on the bottom of the screen under the second column of info where names and device serial numbers should appear.
Type the name of the person, group, whatever you want to identify that assignment by into the blank that pops up after you hit the plus ( + )
Then select the assignment you just made and tohe 'Check Our' button at the bottom. At this point a box will pop up with a window at the top listing all devices supervised by Configurator. There is a tiny down arrow button that opens a scroll down menu to the right of this box. Click that, then select the device connected by USB as the one to assign.
The name of the assignment you gave it will show on the lock screen now and you can assign apps and profiles to the device like you would any other device in your Configurator inventory.
Good Luck.

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?

USB ports no longer charge when PC is off since installing Supercharger

I have an MSI Z77A-G41 (MS-7758) Rev 3.0 running Windows 8 Pro 64 bit - 8GB RAM running the latest BIOS and drivers (used MSI LiveUpdate)
Charging devices with my front USB ports always worked when the PC was off, UNTIL I installed Supercharger from MSI's LiveUpdate utility. Charging does appear to be faster while the PC is on, but it no longer charges my devices when powered off like it did before I installed Supercharger.
I then uninstalled Supercharger, and the PC still will not charge devices when powered off.
I ensured 'EuP 2013' is DISABLED via BIOS ... not sure what else to do and why USB charging while powered off is no longer working. :(

OK, I just figured out what the problem is.
JUSB1 and JUSB2 control the 2 USB ports available to the front of my PC. With my board (MSI Z77A-G41 (MS-7758) Rev 3.0), JUSB1 is NOT red, but it still charges devices connected to it when powered off.
In my situation, the top USB port runs to JUSB1, the bottom runs to JUSB2.
I just realized my device was plugged into the bottom USB port which runs to JUSB2. The top port connected to JUSB1 works fine when the PC is off.
Issue resolved. Thanks for your replies people, I'm good to go!

Charging peripherals while iBook in Sleep Mode or Shut Down (Hot USB Ports)

I would like to be able to charge my iPhone or iPhone while connected to the iBook. However I would prefer the charging method to work in "Sleep Mode" or when the computer is shut down, still plugged into a wall outlet. Has anyone had any success with finding an after-market provider or a solution to get "Hot USB" ports installed on the iBook G4's? I heard in passing this feature would be available soon on the newer Apple notebooks but have yet to see it.

This isn't something I'd noticed before, but my goodness, you're right!
I'm certain I was able to charge my third gen iPod while it was plugged into my sleeping iBook, as long as the iBook was also connected to an outlet.
My MacBook, while sleeping, will charge a device regardless of if it's connected to the outlet or not.
What OS is your iBook running? Maybe that's a clue to solving this issue.
