K7N2G-L USB Ports Disabled?

Everything seemed to be working fine with the motherboard until I tried setting it up for "standby". The first time I clicked on standby when exiting Windows my PC just shut down, so I went into the Bios and set it up so that it would "resume from S3 using USB device". When I saved and exited from the Bios my USB ports no longer functioned at all, the LED indicators don't even blink when the system is starting up. I tried going back into the Bios and changing things back to the way they were but still no function from the USB ports. I even loaded the DEFAULT Bios setup and even tried going back to Bios ver. 3.20, still no results. Anybody else have this kind of problem? Any help would be greatly appreciated.
My System;
Athlon XP 2100 Th
K7N2G-L (not even a month old) BIOS 3.30
Asus 8460 TD (Ti 4600)
Sound Blaster 5.1
256 PC 2100 DDR
430 watt Antec
Global WIN CAK 486 CPU Fan (avg. 50-56 degress)
NOTHING HAS BEEN OVERCLOCKED.

Got it! :D It was the power supply. Although the specifications were OK it wasn't AMD approved (it does have a "P4" sticker on it though). I swapped it for another 300W supply which had better -5v and -12v currents (1.0A and 1.5A instead of 0.5A and 0.8A respectively).
So if anyone else gets a similar problem this solution might help 8)

Imac usb ports disabled and nothing is connected

iMac 27inch Late 2007 USB Ports Disabled Again!
Has happened before and took forever to fix it. Nothing specific fixed it last time and nothing I know was the direct cause. Each time different OS, different location, different year, different cables etc etc.
Now, reset everything, moved everything, changed everything - still nothing. No USB ports work. iMac still has pop up "USB devices disabled..."
Taking into Apple unless someone can tell me what 10 pages of google hasn't - what a bloody stress and waste of time!

USB ports disabled/not working

My USB ports aren't working, one is completely dead and the other supplies power but I receive an error saying the port has been disabled due to the device using "too much power." I have restarted and updated with no luck. The devices work fine on my friend's computers with no error prompts. The laptop is 2 days old and I haven't done anything that should cause a short out, other than removing a USB storage plug without ejecting first.

USB plugs only supply *so much* power to USB devices.
The usual fix is to buy a self-powered exteral USB hub (AC adapter plugged into wall). That takes 95% of the power load off of the MBP.
But then some USB hubs do not play nice with Mac, and some devices do not play nice through an external hub at all due to the additional translation of USB signals.
First thing ... do not repeat overtaxing the USB ports ... only bad comes of that, even though the MBP usually can dened itself from damage -- usually.
Go to macsales.com, see what they recommend for powered USB hubs, since they try hard to be mac-compatible nad may have beter bets thn randomly trying ones from Best Buy or Fry's or Microcenter.

USB port disabled by Palm sync

Got a new Palm, tried to sync with the USB cable connected to the port on my keyboard. Got the error: "port attached to is drawing too much power, will be disabled" after which the port would not function. Did I blow the hardware, or is this a protective mechanism that can be reset with software? Have since tried - hesitantly - on the main USB (2.0) ports on my iMacG5 and it has worked okay.

A reboot should bring back any ports disabled in that fashion.

USB Port disabled. What do I do?

Hello,
I've been attaching a portable hard drive to the back of my IMac OS 10.6.4 since I've owned it (1 1/2 yrs) through a USB port. Tonight, it suddenly said that I'm drawing on too much power through the same port and the port has been disabled. I'm attached to the same hard drive.
How do I get the port back in running condition?

USB ports disabled

installed wireless modem. moved computer to another room. plugged in usb hub with wireless mouse and keyboard only. connected power and booted computer.
got the following message-
"Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled.To prevent damaging your computer, the USB device drawing too much power has been disabled. Other devices may have also been disabled. When you disconnect the device drawing too much power, your other USB devices will be enabled again."
keyboard no longer works, in any port. mouse does work, even when plugged into keyboard's usb. ipod connection seems fine. have done shutdown removing cords then rebooting. removed hub but no change.
how do i get keyboard back

Some USB devices require more power than others. You also can have USB ports that deliver 1.1 USB power, while other deliver 2.0 USB power. You have a device that requires more USB power in a USB port that does not provide that power
Ensure you are not plugging into a Keyboard or Hub USB port.

"USB ports Disabled due to power drain..." error HELP!!!!!!!

Okay, I got the dreaded pop-up saying that my USB ports had been disabled because of too much power drain. Well, I unplugged everything and restart, still get them on boot up. Again, nothing hooked up but the power cord. I've done PRAM/NVRAM resets several times AND SMC resets several times. I've upgraded from snow leopard to lion, I've even created a new user and NOTHING will reset the USB ports. I even downloaded the Xcode 4 developer tools and tech tool pro 6 to see if they have anything that can fix it and nothing helps. Does anyone know of a command line that may force them to restart or an app that will help.
Your help would be much appreciated!

Sounds like your USB hardware may have developed a fault (a short?). Can you take it to an Apple Store?

USB PORTS DISABLED AND WONT WORK FOR ANYTHING

MacBook Pro OS X (10.6.8)
the other day i had plug in a remote helicopter to our computer and came back and same 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.* To prevent damaging your computer, the USB device drawing too much power has been disabled. Other devices may also have been disabled. When you disconnect the device drawing too much power, your other USB devices will be enabled again"

K7N2G-ILSR: Firewire and all but 2 usb ports are gone.

I have the MSI K7N2G-ILSR motherboard. When I first got it I noticed in my bios I had the option to enable/disable my IEEE 1394 ports. After having problems with my video card I updated my bios to v1.7 and since then I've lost that option all together and have noticed that only 2 of my USB ports work and the firewire ports are not detected.
Is this a known bug? I'm going to try and roll the bios back to v1.4 and see if that restores them. If that doesn't work any suggestions?
Also on occation my USB ports will fail to be started by windows and/or linux.

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?

HT1338 Does anyone have a fix for 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" - this is a brand new machine with nothing connected to the USB ports - i've done u

Hi
does anyone know how to fix the message on my iMac:
"Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled."
This is a brand new machine and did not have anything attached to the USB ports"
Thanks for any help

If you are getting that message on a brand new Mac with nothing connected to the USB ports, take it back. It is broken.

IPod Touch drawing too much power--disabling USB ports

Hi there,
I have a brand new Macbook, just picked it up less than a week ago. I've been hooking up my 2nd gen iPod touch to it for a while without any problems, but suddenly I started to get an error message every time I plug it into my USB port:
"*Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled.* To prevent damaging your computer, the USB device drawing too much power has been disabled. Other devices may also have been disabled. When you disconnect the device drawing too much power, your other USB devices will be enabled again."
I've been looking all over the internet for a solution to this and I can't find a thing--it's really frustrating since this laptop's brand new and I have no other way of charging my iPod.
My laptop is plugged in while I'm doing this. The error message is instant--it seems to pop up before I've even inserted the USB cable all the way. Also, for what it's worth, I just did a test and I get the error message just by plugging the USB in, even if it's completely unattached to anything.
Thanks, looking forward to a solution.

What do you use to block/disable USB ports and CD/DVD drives?

I have been tasked with finding software that can disable USB ports not being used for keyboards & mica and CD/DVD devices. At a previous job we used Sophos Enterprise console and it had that ability. I currently use VIPRE Business Premium but I don't see where their products have the same capability. So, what do you gals and guys use?

Most business leaders are always looking for new ways to put money back into their budgets. This is particularly true of small and midsize businesses, which have smaller budgets to begin with. For these companies, the prospect of saving on IT equipment can be especially attractive.Buying previously owned IT equipment can be a great way to achieve the savings that so many businesses are looking for, but it’s important that you take the time to learn exactly what you’re getting before you make such an investment. The terms “used” and “refurbished” are commonly used to describe previously owned IT equipment, but the two are not interchangeable. If you want to make sure the great deal you’re getting is really as great as you think it is, it’s important that you learn what the two terms mean, and how they’re different.Used Vs.

Disabled USB port

Recently, upon starting up my 2008 MacBook Pro, I received a message that said one of my USB ports (the right hand one) was disabled for using too much power. The message also said once whatever device was removed from the port (odd, because I think there never was a device attached to the right-hand port in the first place), it would re-enable the port.
However, it hasn't. Any idea how I can resuscitate this USB port? Because of this, I can no longer sync my iPod because using it with my USB music drive and a USB hub is too stressful for the computer.

Hi
the port has stayed disabled, even after another restart?
reset PRAM & the SMC ? (just in case...)
You've run the apple hardware test, ?
