Mac Pro USB ports and bluetooth not working

Had this same exact problem on my 2010 6-core Mac Pro. All bluetooth and usb stopped responding. I unplugged everything, opened it up, removed all drives and memory tray, and pushed in all cable connections I could see. Put everything back in, closed the case, plugged all my usb/firewire cables back in and it worked perfectly.

Similar problem here. All external ports (USB and FireWire) work intermittently. When importing images from Compact Flash card through an USB adapter, it will download normally for 1-5 min. then suddenly lost contact to the USB port. I unplug and plug right back in then it work again and after a few mins it will re-happen. I use the same card reader on my other iMac and it's working perfectly fine. I also have the original iSight, and it have the same problem. During Facetime, it will cut off automatically; unplug then put it back in and it work again for a little while then cut out again. I also tried to reset the PRAM many times and had no luck.

So far, I don't have problem with external hard drives, only iSight and USB readers. Strange. Are the external ports defective?

Hello, I had the same problem. I use the bluetooth trackpad with my laptop at home and wanted to use it with my mac pro (early 2008) at work but it wasn't working. So I read the trackpad's manual and it says you should unpair the device before pairing it up with another computer. I did that and it worked. I hope the solution will be just as simple for you.

Hey....uh.....may I ask??? Would any of you, by chance, be running Windows 7 Pro as a dual boot on your Mac??? I am having the same issue and not gettng much help from Apple. I cannot run my wireless hardware on my PC side and it really suck....I was wondering if this had any correlation or effect on the USBs and the Bluetooth function!!!!

I have the same problem on my Mac Pro 2.26 GHz Quad-Core. When I first got the computer I only had the Bluetooth issue and I was able to get it working again. In the end I'm not really sure which "fix" did the trick but it was fine for months. Now it's just like the original poster described. It seems like the computer is frozen but it's actually the keyboard & mouse not functioning (Bluetooth mouse, USB keyboard). I can still control the computer through screen sharing or log-me in, thankfully, but it's not a solution to the problem. I have tried everything that I have read to do but, the issue keeps coming back. I'm at a loss, has anyone found a solution?

Exact same problem for me - MacPro running SL.Only just started happening. If i go to "about this mac > bluetooth" it gives me 'no information available'. Could it be as simple as a hardware problem? not looking forward to having to pay my out-of-warranty mac to get investigated.

If you google this there are many, many sites that tell you to reset the pram, switch tht thing off for 15 minutes etc. That actually works for me... for a while. The problem is i dont want to restart the machine, i have a mac pro because it has to do some serious data crunching continuously and so restarting is often an absolute nightmare. I wish there was a solution that didnt involve restart.

only solution i have is to plug a wired mouse in, not failed so far.

I am not using Blutooth but suddenly my USB is not working right. First my mouse and keyboard wouldn't work. Tried plugging them into different ports. After rebooting 3 times, they worked but then I noticed USB devices were still not working--like plugging in a flash drive to the front of my MacPro 2.66 GHz Quad-Core Intel Xeon.

I was going to try resetting the PRAM but as others reported, the keyboard is not working during the reboot so it didn't happen. This is crazy! I hope someone can figure this out soon. Isn't there some little switch inside the Mac that is like resetting the PRAM?

Please help haveing the same issue! all usb ports are not working, no keyboard or mouse!!!

Its weird that you guys are having this issue, because about 5 days ago on the 25th, I to am having an issue with this. All my usb ports are not working. I am not able to get keyboard or mouse to work on the front or back ports. When I plug my mouse in direct, the laser lights up but no movement. I have a 2.66 ghz quad mac pro. I just ordered a pcie card from tigerdirect, which is supposed to come today, I am hoping it does the trick. its a 4 port 2.0 card, it was a bit pricey but I am thinking the mac will pick it up after I plug it in. The 3.0 usb cards all said they needed drivers for it to work, so I just went with the old usb 2.0..keeping my fingers crossed that it will do the trick, if so I will post. I called Techserve yesterday about a possible repair, and of course they want me to bring it in, could be logic board? I would rather just buy another used one on ebay or something then to spend all the money to have this one fixed. I ran out of warranty in 2010 so I'm kind of screwed.

The only thing I've done differently is that I was hooking up music gear to the usb ports. I am using a Lexicon Omega adapter for mixing in Logic 8. Its been working for a week or two now, no issues. This adapter has its own power supply hooked up to it, do you think I overloaded usb, and it just killed the ports? Its been plugged into the back of the machine, why would this effect the front usb ports? I also had to make some changes before the happened, setting the main usb to the lexicon omega adapter. Not sure if this has anything to do with it. I have not done any updating, I am actually still running 10.5. I can't update to 10.6 because my avid media composer 3 won't work, so I never installed snow leapord. Really bummed, this has been my workhorse for a good 4 years now.

ccoates4, my USB is working again but I am not sure why and don't trust it. I shut down for a few minutes when I was having the problem. I think you need to turn off or disconnect everything you can from your Mac and shut it down. Then go ahead and power back up. That seemed to work for me. At least so far, it is working.

Linda..tried that.. I came back yesterday after leaving everything unplugged for half a day, including power chord. Then booted up still no go.

Last night spent a good hour trying various things. trying each port, full power down and restarts. I took out a bunch of ram and all the hard drives except the main drive. machine boots up perfect but still no usb at all.

I took the power chord off again last night, going to give it 24 hours and then try it again tonight when I get home. I am hoping the usb pcie adapter comes today, I think that's going to be the trick just to get my keyboard and mouse working again. I'll post if thats a work around..got this one

from what I'm understanding is its likely to be hardware, my machine is a bit old, and its been getting fussy in its old age... I guess they can't last forever. just got my adapter in the mail so when I get home I am hoping this will be a work around. I'll post for sure if it works.
