Software :: Imac USB Ports Not Working?

Jul 9, 2010

Recently 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.

IMac :: USB Ports Not Working?

Feb 1, 2009

I recently went away for the weekend and when I came back my USB ports don't work. When I first start my 24" iMac the mouse lights up but then goes off later on when it's booting up. I really don't know what to do and i'm not even sure if I got any discs with my iMac as it had Leopard preloaded...

OS X :: USB Ports Just Stopped Working On IMac

Jan 30, 2009

I 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.

Mac Pro :: ACDs USB Ports Not Working

Aug 5, 2008

All 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 Not Working - Works In Windows

Feb 3, 2009

When 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?

Software :: USB Ports Not Working After Reboot On MBP 10.5.5

Oct 12, 2008

My 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:

10/9/08 10:53:10 AM kernel USBF: 164149.607 AppleUSBEHCI[0x4167000]::Found a transaction which hasn't moved in 5 seconds on bus 0xfa, timing out! (Addr: 2, EP: 10)
10/9/08 10:55:11 AM kernel USBF: 164270.621 AppleUSBEHCI[0x4167000]::Found a transaction which hasn't moved in 5 seconds on bus 0xfa, timing out! (Addr: 2, EP: 10)

What is the terminal commands needed to reinstall the default USB port drivers for OS X 10.5.5?

Power Mac G5 :: USB Ports Not Working, IPod, IPhone Not Charging Or Syncing?

Dec 13, 2007

I 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, 2010

I 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, 2012

This 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.

iMac, Mac OS X (10.4.11)

PowerPC :: Usb Ports Not Working Fine / Mouse Light Flickers And Keyboard Does Not Work

Sep 17, 2009

My 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?

PowerPC :: How To Add USB Ports On IMac G3

Jun 13, 2007

would it be possible to solder any wires to get power onto the USB ports on a G3 iMac? I have a blue 500Mhz model, if that would make any difference. the reason that I want to do this is because all of the iPods use USB now, and I would like to be able to charge mine while I am syncing it.

OS X :: When Are IMac USB Ports Powered?

Dec 21, 2008

I occasionally have trouble charging my iPhone via my iMac USB ports. I plug in the iPhone, the screen indicators change to show that the phone is charging (green battery indicator and the lightning bolt symbol). However, when I come back to the phone several hours later, the charge indicator hasn't advanced any. For example, if the indicator showed half-full when I plugged it in, it remains half-full.

The iMac does go to sleep a few minutes after I leave it, but sleep has never precluded an iPhone battery charge on my MacBook, and most of the time it works on the iMac.

Is there anything, besides shutting down a computer, that causes a USB port to unpower while the iMac is sleeping? Does it matter whether I am logged in or simply at the login screen?

So i can make an imac function as an external monitor by using a display port to display port cable. i would like to know if the usb ports on the imac will also function for a connected laptop? Most other monitors have extra usb ports and would be cool if they worked on the imac as an external monitor for a laptop.

IMac (Intel) :: Output Same Signal Through Both Display Ports At Once?

Sep 8, 2014

I'm looking to run video out to two TVs, but it's over a decent distance, so I'm worried that using an HDMI splitter would cut the signal and suffer quality loss. I was wondering if both mini DisplayPorts can be linked to output the same signal at the same time, so that both TVs can show the same thing but each signal is at full force. 

Info:
iMac
