OS X :: PowerMac Wont Restart / USB Ports Deactivated
Sep 23, 2008My G4 PowerMac QS 733 running 10.5 wont restart. My daughter says it was going when she used it, but that a message came up that the USB port which had the mouse in it was being deactivated because it was drawing too much power. I think the mouses cord was damaged. She moved the mouse around the ports, and the computer deactivated them all and then shut it self down!
I have tried plugging in other keyboards and another mouse, but to no avail. I have unplugged everything, including power. Now the when I try to restart, the start up light on both the screen and tower just flash as if the Mac is asleep, but the Mac doesnt start up and I get no start up tone.

Mac Pro :: ACDs USB Ports Not Working
Aug 5, 2008All of a sudden a few days ago, I realized that my keyboard was not working. It was plugged into my 23" ACD. So I unplugged it and put it into my Mac Pro. It worked. So I decided that my ACD's USB ports were not working. A phone call to AppleCare and he told me to take the display for repair to the Apple Store. I just did that, and the USB's worked fine in the store. I take it home, still does not work. So I thought my USB ports on my Mac Pro must be bad. But everything else I plug into all three of the back ones works just fine; but my ACD does not. In the store, he used all of my own cables / power adapter. Why is my USB not working for my ACD but it is for everything else?

OS X :: USB Ports Just Stopped Working On IMac
Jan 30, 2009I have a aluminum iMac, which has been working fine until now. A couple of hours ago I restarted it and went and did something else for a couple of hours. I then came back to find my keyboard and mouse not working, I double checked and they were both plugged in fine (I use the aluminum apple keyboard and a kensington mouse). I restarted my computer but it still did not fix the problem (I was still stuck at the login screen). I thought it might be the USB, so I plugged my iPod in, and it did not charge. While my iPod was still connected to my computer I restarted it again and as soon as the screen turned grey my iPod started charging and my mouse worked (the light turned on), but only until the grey apple logo appeared and it then stopped working again. I have tried every USB slot and none of them work. I'm pretty sure my computer was completely updated as well.

Feb 3, 2009When I started up my iMac the USB ports stopped working. It didn't respond at all. The weird thing is that they work at the startup when you choose between Windows/Mac OS X when holding in ALT. They also work in Windows, but not in OS X. Does anyone know how to solve this problem?

Oct 12, 2008My USB ports stopped working after a reboot. I have rebooted multiple times and have full updates. printer and usb mouse dongle dont work on ALL SUB ports on my MBP. I installed fresh version REAL of OSX 10.5.5 I bought. 3 months later and now I have this small hickup. Recent install was XAMPP. My USB ports on my MacBook Pro stopped working. (Read error codes at end of message). To test if they are completely dead I did the following:
I boot up, and I move the mouse around waiting for the mouse to wirelessly talk to the USB port mouse dongle. As the desktop is loading, they pair, the mouse moves a few inches and then stops (seems to stay on for only 2 tenths of a second), then the port dies. So I assume the driver for the port is turning on, then immediately off. I have the following error in my Console when I unplug then plug in the mouse USB dongle:

Software :: Imac USB Ports Not Working?
Jul 9, 2010Recently I changed my 4-port USB hub for a 7-port hub. Now 2 USB ports are dead, and the third port will only accept self-powered devices, such as external drives, a printer, or memory sticks. I dare not plug in a hub, so I am faced with a lot of plug-swapping.

OS X :: MacBook Trackpad And Keyboard Not Working On Restart?
Jan 10, 2009I was just using my Macbook normally and it came up with an error like IP was in use or something with the red exclamation mark. The my internet stopped working so I just restarted it. Now my Macbook is literally not working? I can turn it on but when I get to the login screen, my mouse or keyboard are not working! So all I can do is hold the power button to turn off. It appears OSX is still running fine though because the screen dims after a while and the flashing | in the name input bar is still flashing.

Dec 13, 2007I have had an intermittent problem. Every so often (once a month), my iPhone will not connect to my computer, it does not charge, nor does it show up in iTunes. I checked out 3 different cables, and none work (cable problem eliminated), I tried 3 different iPods, none charged or showed up (iPhone and iPod problem eliminated). I tried both the front and the rear USB ports and nothing ever happens. As far as I recall, this problem just cures itself after a few days. Any idea what I need to have repaired to stop this maddening problem?

Mac Pro :: Firewire Ports Stopped Working / Resetting PRAM And NVRAM
Sep 3, 2010I have a 2006 Mac Pro and recently my firewire ports stopped working (front and back). I did a little searching around found a suggestion to try resetting the Mac's PRAM and NVRAM by holding the Cmd-Option-P-R keys down while booting. I have tried this numerous times and it doesn't seem to do anything (i.e. the Mac just loads OS X and doesn't re-boot like the instructions say). I'm using a MS Wireless Comfort Keyboard for Mac. Can you reset using a wireless keyboard?
Since I wasn't making any progress with that, I was toying with bringing in the Mac to a genius bar. Never having used the genius bar before - how does it work? Do I bring the computer in and leave it with them? Do they work on it while I'm there? I don't have an extended warranty so do they charge time and materials? I'm wondering if that might get awfully expensive and if I ought to just buy a PCI-X firewire card instead.
Any suggestions?

OS X V10.4 :: USB Warning And Ports Not Working After Update To Snow Leopard From Tiger
Apr 14, 2012This morning I've installed OS Snow Leopard 10.6.3 on my iMac, previously I had OS Tiger 10.4.11 running. Everything seemed fine until I restarted and then I started getting "USB drawing too much power" promps all over the place even though the only thing that's attached to the iMac is the keyboard and the mouse (they both work fine). The process went like this:The iMac is a 2.4 GHz Intel Core Duo from october 2007First I did an upgrade of my RAM, from 1GB to 2GB, that went ok.Then I runned the install dvd for Snow Leopard, I did not perform a clean install, just did it over my old data. After restart, everything worked but i got this USB warning message, one of them. At that point my usb's still worked, (even though the warning) I could print and scan. To get rid of the warning, i resetted the PRAM and SMC. After doing so, the promps multiplied and my usb ports ceased working, except for the keyboard and the mouse attached to it.I've done the Apple Hardware Test, and it gives no malfunctions.Firewire works fine, Isight buildt-in camera and bluetooth too.I've tried all usb's and the keyboard will work in all of them, not like my printer and scanner which are completely ignored.USB power warning also appears at restart with no deviced connected (no keyboard and mouse, i've tried).I've also found in many forum entries the possibility of a problem on the logic board, but since i've never had a problem with my imac until today i would not be sure about a hardware malfunction.The last thing i've found around that could be a clue is something about the kernel extensions, but that's complete chinese for me, I'm a mac plug&play user and not too much of a mac expert.

PowerPC :: Usb Ports Not Working Fine / Mouse Light Flickers And Keyboard Does Not Work
Sep 17, 2009My friend just got a 1.25GHz MDD but he says he is having problems with it. He says that when he starts it up, his mouse light (sensor) flickers and the keyboard does not work. The only way to fix this is to unplug and replug in the peripherals. He also tried on his Studio Display connected via ADC and the same thing happens. Could a PCI USB card help his problems or is there some way to fix the current USB ports?
