Right Side USB Ports Don't Work on my DV7 6b32US

I just bought a DV7 6b32US.
It's on Windows 7 Home Premium.
The left hand side USB slots are okay. but the two on the right side do nothing at all. No message - nada!
It seems to be a common issue, but I have no resolution to it.
Also, annoyingly, when I logged on to the HP site to try and find drivers, the laptop's serial number is recognized as a Compaq.
Anyone able to help?
Thanks in advance

Hello everyone. I understand you're having issues with non-functional USB ports. I suggest trying the following.
Go to Device Manager.
Expand the "Universal Serial Bus Controllers" section.
Remove all "host controllers."
Shut down the notebook.
Remove battery and AC power.
Hold power button for 20-30 seconds.
Replace battery and AC power.
Boot notebook and allow Windows to reinstall the host controllers.
Reboot one more time.
Verify that this resolves the issue.
Let me know the result. I hope you all have a Happy Holiday!
Please click the white star under my name to give me Kudos as a way to say "Thanks!"

Right side USB port does not recognize mouse while in Vista

Ok, heres the deal. I use a corded USB mouse with my MacBook Pro. I am right handed, so I usually plug the mouse into the right side USB port. It works just fine while I am booted into OSX, but while in Vista, the mouse is not recognized at all when it is plugged into the right side. The mouse still works on the left side port just fine.
The weird thing is that I can still use that same right side USB port for my flash drive or iPod or anything else. Just not my mouse. Anybody else have this issue or have any input?
Thanks

Am I the only one with this problem? I am going to try to uninstall the mouse drivers in vista and then reinstall them and see if that does anything.

MacBook Pro Retina USB 2.0 devices not working in right side USB port

4 days ago I bought MacBook Pro Retina 15".
When I plug USB 2.0 device to right side USB port, it does not work. OSX does not recognize it, iPhone does not charge, and so.
When I plug the same USB 2.0 device to left side USB port, it works.
When I plug USB 3.0 device to left or right side USB ports, it works without a problem.
Does anyone have this same issue? How did you resolve it?

I have a similar issue with a 13" Retina. Both my ports work OK for most USB devices but the right one won't work with a USB external HD (Time Machine backup). Very consistant.

After update to OS X 10.7.5 on my Mac Pro (2009) USB ports don't work at all after wake up from sleep mode; with 10.7.4 there was (nearly) any problem.

hello,
after update to OS X 10.7.5 on my Mac Pro (2009) USB ports don't work at all after wake up from sleep mode; with 10.7.4 there was (nearly) any problem.
the used ports appear to be "killed"; the unused USB ports seem to work, but the Mac works in slow-motion.
The only "solution" is to restart my Mac.
- SMC-reset, PRAM-reset or repairing user rights had no positive effect; what is the solution - a bug-fix-update???

I have a mac mini (A1283) with OS 10.7.4. Upon upgrading to 10.7.5 it did not start up again. Instead, the light was on and the hard drive did not start up. The light on the connected USB mouse was not lit.
My solution:
Cold start with Command-v pressed.
This should start Verbose mode (see http://support.apple.com/kb/HT1492 ).
What happened on my mac mini was that the grey startup screen with the Apple logo appeared for a long while before the login screen came.
Maybe Cmd-v set open firmware params and fixed some corruption.
Anyway: my mac mini works again.

Modem problems on Right Side USB port

I have mentioned this problem in a couple of other threads here, but I just got some news from Apple, so I thought it might be worthwhile to start a new thread. As you can see below, I have a MacBook Pro/15"/1.83, running 10.4.7, manufactured in week 13. When I went on a trip to the "Mainland" (I live in Hawaii) last month, I discovered that the USB port on the right side of the computer didn't work properly with my Apple USB modem. While I could get a dial-up connection, I couldn't maintain it, and it would hang up within a minute or two. Everything worked normally on the left side USB port. I brought the computer into the Honolulu Apple Store, and they confirmed the problem. They also booted the computer off an external drive, and it worked fine. I wiped the drive, and reloaded everything, and the right USB port still didn't work. I then sent the computer in for repair, twice now. The first time they also wiped the drive and sent it back to me. Second time, they kept it for 2 weeks, but were unable to find a problem. Sure enough, I still have the problem on the right side USB port. However, I also discovered I could do a backup of my user folders (~3 GB) onto an external USB drive from the right port with no problem.
Anyway, I just finished speaking with the Apple Rep, who told me there are other MBPs with the same problem, and they are investigating it. They said I should keep an eye on the Apple Support site for possible software/hardware fixes.
Hope they fix it soon. I do want to say that the people I spoke to have always been helpful.

Hello...
Even though I just got this USB Modem yesterday (as I have a trip to a place with no wireless or ethernet connection), and I haven't had the chance to test things out enough, I would like to report that I have the EXACT same problem, although I did connect several times from the RIGHT-side port (and even so, it was only for a few minutes, if I connected at all).
The LEFT port has now worked for 24 minutes straight, so, I think that that is the issue. There is a clear difference between the RIGHT port and the LEFT port, and I seriously doubt that it is the service provider.
I will continue to use the LEFT port until I find out more about what is going on. Very strange indeed.

USB ports don't work - 880GMS

HELP ME
My usb ports work fine until Sunday, I restart the W8 OS and they don't work (my last activity was configure a router but I didn't install anything). I've two OS (W8 and Ubuntu 11.1) and I tried all and my USB ports don't work. I don't have any idea about the cause of the problem. All work fine except my USB ports. They are enable according to the BIOS but the OS (W8, W7 or Ubuntu) doesn't recognize any device.
I tried this things:
- Change my porwer supply
- Restart the BIOS to the Fail-Safe and Optimal value default
- Clear the CMOS (Changing the jumper and remove the battery)
- Remove the W8 and install W7
- Remove W7 and install Ubuntu 11.04
- Flash the BIOS to the last update (it's the same that was loaded in the BIOS)
Currently, I don't know what I must do it. I'm really disappointed with this board (MSI 880GMS-E35). This is my second problem with these model. Previously, I've one and it didn't supply the energy to start the proccesor (Phenon X4 955). My actual board works fine until Sunday.
Please help me to solve the problem.

OK, I have no idea but fortunately my usb ports work fine now.
I don't know how to fix the problem. But I can assure that thanks to Ubuntu it's fixed. My last two operations were:
- Flash the BIOS
- Check lsusb
Yesterday, I'm full disappointed and I was going to prepare my hard discussion with my provider when suddenly I found a this post:
http://askubuntu.com/questions/69594/my-usb-ports-randomly-stop-working-till-a-reboot
But before to enter the command in the Ubuntu's console, I saw that my USB devices work. It's amazing!!! I'm a newer electronic engineer and I saw events similar that this more than once time in my labs (Typical student experiences).
If anyone has the same problem, I could recommend:
- Check BIOS usb options
If these are ok, else enable the propertly options
- Check # lsusb (In Linux)
If your ports don't appear check the PSU (Maybe there are others things that you should check) else
- Check # dmesg | tail (Before and after to connect a usb device)
If there is an error saw in forums, maybe it's the common problem so far (Incompatibility in the kernel -error hci-)
- Type # acpi = force irqpoll
ELSE
- Flash the bios as show in this forum
ACLARATION: I think that this algorithm might help you but I don't prove this. It's your responsible to do that. I only write the items that I learn with this issue.
CONCLUSION: I don't wish that anyone has this problem. I lost one week trying to solve it.

When I connected my iPod Classic or iPhone 4S to the right side USB port of my 2012 11 inches Macbook Air (128 GB SSD), I get a message from iTunes that I connected my device to a USB 1.1 port. I checked the specs, it's a USB 3 port. What's wrong?

Compag Laptop Right Side USB Port not working

I have a week old Compaq CQ56-115DX. Today for the first time I tried using a flash drive, first in the port on the right side. I didn't get any tones or pop-ups, like you'd normally expect. Then I tried the two on the left side. No problem with them. I wonder if this right-side port has some special configuration, like for some specific use that wouldn't respond to a flash drive. I see no alerts (yellow triangles) in Device Manager. I have read a few things on the Web about reinstalling USB devices, but thought I'd check here first for advice.
Solved!
Go to Solution.

That wouldn't be the problem (a dedicated port). The frontside ports of some machines have less power then rear facing ones in general, due to how they are connected, but in your situation, this wouldn't apply. I would definitely try the reinstallation of the USB drivers (uninstall and allow to refind) and if not, bring it back to the store since by your post, you indicate it's within the return period (14 days from date of purchase). Definitely, all your USB ports should be working.
To receive your in-store service, you will need to take your computer to your nearest Best Buy location. When you arrive at the store, please take your computer directly to the Geek Squad counter where one of the Counter Intelligence Agents will be happy to help you. I would take everything with you (box and all) in the event that an exchange is needed of that device.

Right side USB port is not functional on my new Spectre13

I just purchased a new Spectre13 notebook and the USB port on the right side isn't functionnal. I searched in different places in the system and I cannot find a way to get it working. Is this normal?

And now the left side USB port doesn't recognise my 16GB USB key anymore. It does recognise a Logitech wireless mouse key but not my key.
Since it works fine on My MacBook, I know the problem isn't the USB key.

USB ports don't work after resuming from standby with Windows 8 on X230 tablet

I have just done a clean install of Windows 8 on my X230 tablet. Before installing Windows 8 I installed the most recent BIOS for this machine (version 2.50). After installing Windows 8 I installed System Update from the Lenovo Website and downloaded all the recommended drivers and other files. I've also installed all the latest Windows 8 updates.
Here are the symptoms of my problem: After resuming from standby/sleep mode, my USB ports do not work. My computer has two USB 3.0 ports and one USB 2.0 ports. All exhibit the same behavior. After resuming from standby mode I have tried inserting both my mouse and a USB thumbdrive, but neither are recognized. After restarting Windows, the USB ports work again... until I resume from standby mode again.
I hope there is a solution to this issue. It is very frustrating.

Thanks for the suggestion about tweaking the "Allow this computer to turn off this device" feature. I un-checked that box for every entry I could find under "Universal Serial Bus Controllers" in the Devide Manager. Unfortunately, the same symptoms of my problem persisted.
I went back and looked at the README file associated with the BIOS 2.50 download on Lenvo's support site. At the bottom of the file it gives a "Summary of Changes". Under version 2.03 of the BIOS (the version just before version 2.50), it says:
- (Fix) Fixed an issue where USB device might not detected when system resume from sleep mode.
This indicates that Lenovo support was already aware of such issues. The problem was intended to be fixed in version 2.03 of the BIOS. However, the issue persists on my machine, even with the latest BIOS.
Hopefully someone from Lenovo can comment here.

Cd/dvd burner and usb ports don't work with itunes

I got a 7th_generation_ipod_nano for Christmas and when I downloaded itunes I discovered my cd/dvd device disappeared and my usb ports no longer worked. I tried a fix and that failed so did a system recovery to the time prior to my itunes download. My ports and cd/dvd worked normally. I then re-downloaded itunes and again the ports and cd/dvd failed and again I did a system recovery and again they worked normally. Anyone got a clue? I noticed I am not the only onw with this problem and am wondering if its a bug in the new download. Any help most appreciated. Thanks!

I discovered the answer to my own problem and anyone else out there who needs it here it is: If you have itunes installed on your computer and cd/dvd device is not working do a system restore to a time prior to the dl of itunes. Check to make sure your cd/dvd works again. If it does, then all you need to do is make sure your ipod is NOT connected to your computer while you download itunes again. Should fix the problem.

My Toshiba Satellite A660 USB ports don't work and the webcam doesn't either.

For some odd reason all my USB ports doesn't work. It worked fine with I got it and this laptop is pretty much new. I also tried to uninstall and install the USB device back but I always get an error saying it didn't work. Any solutions to fix this?
Also, my webcam doesn't work. Every time I log into my laptop I always get this error saying "Web camera initialization failed. Please check your camera device and restart application or computer." I have no idea how to fix this. Can anyone help me out please?

For your USB ports, try this one first..
1. Make sure that the power light is off.
2. Unplug you AC adapter form your laptop then remove the battery.
3. Without those two, hold down the power button for 10 seconds then release it. After that put the battery and the AC adapter in.
4. Turn NB on and just choose start windows normally.
This is the simplest thing that you can do. Basically, the reason behind this is because it will reset the microprocessor on your system board. Try this first then if it failed check these links:
USB port may stop working after you remove or insert a USB device
Tips for solving problems with USB devices
For your webcam, you said it is giving out a message "Web camera initialization failed. Please check your camera device and restart application or computer.", that means the application is not installed properly. You only need to uninstall it first from Start > Control Panel > Programs and Features (make sure that view should be in large icons) then look for the Web Camera Application (looking at your laptop model I assume it's Toshiba Camera Application) then uninstall it. To reinstall it back, pull up the Toshiba Application Installer by going to Start then type in Toshiba Application Installer. Once you got it pulled up, click on Next Button and look for the application that has a name webcamera from the list and install it.

Right Side USB Port not working

DVI to ADC Adapter + Mini DVI to DVI Adapter = usb ports don't work?

I have a 23" Cinema with the ADC plug. I've been using it with the DVI to ADC adapter for many years, though I did not use any of the monitor's usb ports during this time. I recently bought a new Macbook, so now I have am combining a Mini DVI to DVI adapter with the DVI to ADC adapter. The display works fine, but now I find the usb ports on the monitor do not work. I've checked all the pins involved and they are all straight and look normal.
Does this have anything to do with the double adapter situation, or could it just be that the monitor's usb ports are aging and haven't been used in a long time? Or is it possible these ports do not support usb 2.0 devices?

Thank you Malcolm.
It's true I cannot adjust the display's brightness using the buttons on the monitor. But I can put the Macbook to sleep, both when the adapter's usb cable is plugged in and when it's not.
So if the usb circuitry has gone bad, will this cause me any other problems, or can I just ignore it? Right now I am trying to choose an external hard drive to buy, so I'm taking stock of my available ports. I don't think I'd put a big hard drive on a usb 1.1 port anyways.

Since upgrading to Lion 10.7.3 my USB ports don't work for anything. Any ideas?

I have been a long-term (nearly 25 years) Apple User, so am reasonably familiar with the system. I upgraded about 1 week ago with an automatic update to Lion and since then I have had massive problems using the USB ports on my Mac Pro (which is from 2009). At first this affected every USB port and I couldn't use my keyboard or mouse, but since restarting a couple of times, and repeatedly inserting and removing them into the various rear ports, I can use these plugged in via monitor cable.
However, the USB ports for other devices are extremely problematic and frustrating as nothing seems to work consistently on them. This affects all devices that I usually access (and which all worked seamlessly before upgrade), including my iPhone (which will power up but not be recognized when plugged into any front or rear port), external drives, cameras, and my printer. However, for the printer only (a Brother MFC 9840) it will work some times if I restart the computer, but not others. I have tried rebooting, switching ports, using other cables, changing power cords. I have read multiple threads on USB issues with Lion for a solution including those to do with printers (https://discussions.apple.com/thread/3301218?start=0&tstart=0), those to do with external drives (https://discussions.apple.com/thread/3510032?start=30&tstart=0), and even those to to with modems (https://discussions.apple.com/thread/3164614?start=0&tstart=0). Despite this, I note that there appear to be no consistent solutions reported and that in other support threads including reseting PRAM. I do see many more problems than I would have expected.
I don't know if this is related, but after the upgrade I also had problems with Outlook not working, but for some reason that seemed to stop after a couple of days. Just in case I also checked to see if I was affected by the malware program (https://discussions.apple.com/thread/3856206?tstart=30), but thankfully I am not.
I am sure this has to do with the upgrade to Lion 10.7.3, and have been expecting something from Apple to address these issues, but nothing so far. I am completely lost for solutions, and any help gratefully received.
Slightly unrelated, but again speaking to a possible change in culture in Apple that has seen upgrades cause more problems than they solve, I am also affected by the change from MobileMe to iCloud and the loss of push e-mail. For those not aware, this has been an issue for more than 6 months, and on the discussion there are now 35 pages of comments, and no solution in sight (https://discussions.apple.com/message/18050375?ac_cid=142432#18050375).

Generally speaking, a full recharge and reboot after the recharge will solve the issue with the ports. Many ports will also start to fail if you leave devices hooked up to them when the machine is asleep. Unfortunately, many non-Apple devices don't understand the low power mode ports go into after Energy Saver is woken up, and only a reboot solves that problem.
