My firewire 800 and USB ports on not functioning!

My firewire 800 and USB ports on not functioning, I believe it is an issue the next driver loaders anyone, know how I can reset these?

You don't "reset" a driver (kext). And I don't believe it s a driver problem. However you might try doing a smc and pram reset to see if that "shakes the ports loose". Might work. Couldn't hurt to try.

FireWire 800 and USB bus failure

I am trying to resolve an ongoing issue with my iMac. External storage devices will not stay mounted. I have had data corruption and several drive failures that I believe are attributable to the sudden loss of connection to the computer. It can not be that all my drives – there have been five – are faulty. My newest drive, an OWC Mercury Elite Pro connected to the FireWire 800 bus, is beginning to exhibit the same behavior, and this drive is less than a month old.
What possible explanations are there for a FireWire or USB bus to suddenly drop a connected hard drive?
Thanks in advance.

Simplest explanation? Your iMac has a hardware failure. Take it in for service. It's probably NOT a software issue but a hardware failure.
Can we assume you have tried new or different cables?

Sound and USB ports suddenly not working

I have HP pavilion dm3-1103au which i bought about 3 years ago.. Everything was worked fine since the first time I use this notebook until about 3 weeks ago when I used it to watch a film suddenly the sound changed to noise sound and then my notebook sound not coming out at all from speaker and headset.. Then I restarted my notebook and then the sound working normally but after a moment the sound stop coming out again..
I check my sound driver to see any updates but it say my driver are up to date.. Then I go to sound control and test my speakers but it shows a warning that says "the device is being used by another application. Please close any devices that are playing audio to this device and then try again." I dont know what application that is using the sound because it happen when I didnt open any app..
After about several days later, the problem seems to became worst.. All USB ports suddenly have a problem too.. My USB mouse stop working at random time.. Then I try to insert my flashdisk and sometimes it can be recognized but when I try to copy files to my flashsdisk, it disconnected when the process of copying has not finished..
when i go to device manager the 'standard openHCD USB Host Controller' have a warning sign.. I check for updates but it says the driver was up to date.. So I try to uninstall it and restart my notebook.. but it didnt solve the problem..
I have reinstall and upgrade my windows from windows 7 to windows 8 but it still have the same problem and become worst.. now the sound not coming out at all from the speakers and headset from the windows starts.. Please help me.. I have no idea what cause the problems.. I think it's not hardware related..

Hello lynz00,
Did you check out this page to see if your computer has been tested by HP with Windows 8, prior to upgrading to Windows 8?
HP is not going to support hardware for Windows 8 on any system purchased before Oct 1st 2011. I realize your issue began prior to upgrading to Windows 8, but don't think the upgrade is the way to fix it.
Did you backup everything in Windows 7 in order to downgrade, prior to upgrading to Windows 8?

FireWire 800 and 400 ports??

What is the difference between these and can you plug any devices into either?

FireWire 800 rocks! It has twice the throughput of FireWire 400. 100 MB/sec versus 50 MB/sec. They do have different connectors, but you can buy adapters. And like the last guy said, a FW400 device will not run at FW800 speeds. I use a FW 800 drive, and it's pretty zippy, but without a RAID config you're not likely to spit out 100 MB/sec of data!
Hope this helps.

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.

No sound and USB ports do not work.

PLEASE someone help.

Sorry I forgot to add that i have a Satellite A665-S6086.

Rear Firewire 800 and 400 Ports

I'm having an issue getting a new Maxtor HD to be recognized by my G5. The front FW 400 port works fine, but I can't get the two rear ports to recognize the unit.
I've tried the shutdown and power plug pull technique but that didn't work.
Any other ideas?
Or does this box have to go in for repairs?
??? Thanks

You could try the Official firewire reset
Mike Mihalik, LaCie
"Seems like the FireWire issue needs to be revisited quite often. Here is my often repeated suggestion which appears to clear up many FireWire issues: reset the FireWire ports. Panther has a Finder Preference to show mounted volumes on the Desktop. You must set this for mounted drives to be visible. Please follow these instructions to reset your FireWire port.
http://docs.info.apple.com/article.html?artnum=88338
Here is a summary:
* shut down and disconnect all external drives and peripherals ; make sure nothing is connected to the FireWire ports
* use Apple Disk Utility to repair permissions on your internal boot drive
* shut down and disconnect the AC power from the computer as well as the drives; if laptop, also remove battery
* let sit unpowered and unconnected for 15 minutes
* reconnect AC power to only the computer (battery too if laptop)
* restart computer
* verify that FireWire ports are visible within Apple System Profiler
* reconnect FireWire drive (only one); refresh window within Apple System Profiler to rescan the FireWire bus; confirm that drive is visible
* confirm drive is OK by using Apple Disk Utility and apply First Aid
* repeat for other drives, one at a time "
Post again if it doesn't help.

MacPro Front Firewire and USB Ports Acting Up

Devices connected to the front firewire 800 and USB ports on my MacPro are acting up. (2x2.66GHz dual-core, early 2007) I put a firewire rugged LaCie onto the firewire port and the MacPro hung. The drive works fine on my MacBook. On the MacPro, the CPU on all cores ran up to 100% and the machine became inaccessible. I put a 80 GB video iPod on the USB port and it could not sync without errors. Could not eject the iPod - OS X reported that an application was accessing the device, even though nothing was running.
It seems as though connecting devices to the front ports initiates a process that does not behave and/or teminate correctly. All other ports work OK, including those on the back of the machine and the USB and firewire ports on my Cinema display.

OK, a couple of things. First, have you tried another USB cable? You may have one that is flaky at USB2 speeds which can cause all sorts of mischief.
Have you tried both "free" USB ports on the machine, or the USB port on the machine that you have the keyboard hooked to?
Finally, you may find some information in your system log that would point to the answer.
In my own experience, USB2 on the G5 has not been capable of reaching serious transfer rates. While I get transfer rates close to 60 MB/sec through FW800, I have never gotten more than about 13 MB/sec through USB2, using several flavors of external drive/SATA toaster/enclosure interfaces. However, I have also had bad USB cables lock the machine up like the Tin Man.

HP Pavilion dv6-6b10tx two of the usb ports are not working

I have recently bought a HP Pavilion dv6-6b10tx....and had it fixed by hp for a problem with the beeping noise.
After sending my laptop for repairs( replacing the system board), I received my laptop but two of my usb ports are not functioning...
I did a bios update and did the hp update to see if it actually fix anything but not luck. So I went device manager and found a exclamation mark on the renesas electronics usb 3.0 host controller with a device status 'This device cannot start. (Code 10)'. What do i do??

The question is why is the port not working? Is something in the port that you can see? If not, then there isn't much you can do but take the computer in to the genius bar and have the techs see if it is a circuit problem that can be fixed.

HT201412 my iphone is showing only i tunes logo an arrow and usb port on the screen

This means you need to connect your iPhone to iTunes on your computer via USB and restore.

I plugged in my ipod and now i get the error message: Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled" - i have a MAcBook pro and now my USB ports do not work - can anyone help me ???

Sometimes you have to reset the SMC two or three times for it to work, don't know why. I've seen that error message before and 100% of the time it was fixed with an SMC reset. I suppose it's possible that your keyboard or mouse IS drawing too much power, do you have access to another you could try?

Audio output and left USB port is not working!

Hi! I have MacBook Air 13" late 2010, Audio output and left USB port is not working!
What happened?
Part No.: Z0JH000TE RS

If the left USB port doesnt work with an external mouse its seems to be a hardware malfunction of this USB port.
The newest BIOS is already installed?
Have you removed all USB ports from device manager and restarted your notebook?
If you have already tried this, contact an authorized service provider. The guys can try to fix this issue and it should be covered by warranty, if you still have warranty on this notebook. :)

Have you updated iTunes with the absolute latest software? If you have not in a long time, your iPad won't be recognized.

No Mac Pro only has Firewire and USB. Perhaps you've misidentified the computer:
