Keyboard USB port problem.

Hey, I recently tried to connect an old PocketPC to charge, it didn't work. Instead, I got a little popup box on the mac saying that the device was drawing too much power and something about the port being turned off.
How do I reactivate the port as now it's nonfunctional.

Hello RockinPunk
Devices that require charging should be plugged into one of the ports on the back of the iMac or better yet a powered hub. Have a look at: http://docs.info.apple.com/article.html?artnum=43023 and the other related article there in.
The following article: http://support.apple.com/kb/HT1151?viewlocale=en_US should help you get the port reset!

How to fix the Superdrive from killing the keyboard usb port?

IF the Superdrive is plugged into the iMac USB port, the keyboard USB port indicates that there is not enough power for the thumb drive or other device. If the Superdrive is unplugged, all is well on the keyboard USB port.
Any fixes for this?

Hi there, I have the same problem on a 27" iMac: when the superdrive is connected to a USB port on the Mac, the USB ports on the keyboard seem to lose all power, even for a USB key.
I called Apple and they told me to reset SMC, PRAM and VRAM but to no avail.
I will try with another keyboard as they seem to say it could be a keyboard problem (which a very much doubt...)

IMac has stopped charging via the keyboard USB port when sleeping - why?

I have a 2008 model 2.8GHz iMac with standard size aliminium keyboard. Historically, I have plugged my iPhone in to the USB port of the aliminium keyboard via the standard iPhone cable and when I put the iMac to sleep it continues to charge the iPhone.
However, the keyboard USB port no longer keeps charging the iPhone when I put the iMac to sleep. The USB ports on the back still do, but not those on the keyboard. Has anyone else encountered this and found a solution?

Although I have never connected my iPod to the keyboard in the past, I can confirm this behavior. Previously my Mac was an Early 2006 iMac Core Duo with the white plastic Apple Keyboard, so the USB hub in the keyboard was USB 1.1 and not recommended for iPods. Now I have a new Early 2009 Mac mini with the aluminum Apple Keyboard with Numeric Keypad with the USB 2.0 hub.
I can confirm that, based on the messages/symbols displayed on the iPod;
1. an iPod connected to the USB 2.0 hub in the Apple Keyboard charges when the Mac is awake.
2. an iPod connected to the USB 2.0 hub in the Apple Keyboard is ejected and no longer charges when the Mac is asleep.
3. an iPod connected to a 3rd party, non-powered, USB 2.0 hub connected directly to a Mac USB port is ejected but continues to charge when the Mac is put to sleep.
4. an iPod connected directly to a Mac USB port is ejected but continues to charge when the Mac is put to sleep.
However, Benjamin, if you read the the 3rd comment from the bottom, of the discussion thread to which you have linked, the poster states that Apple engineers have confirmed to him that;
1. with Mac OS X 10.5.6 a new power management scheme was implemented.
2. an iPod connected to the USB 2.0 hub in the Apple Keyboard is ejected and no longer charges when the Mac is asleep, is now correct behavior under the new power management scheme.
The drawback is that folks in that thread are reporting that not only does the iPod not charge, but that it is drained of power.

HP DV6c63sl USB ports problem, (Unknown Device)..

Hello,
I have a problem with my USB ports, when I connect my phone with it's USB cable, it's shown as "Unknow Device" and that's just in my laptop.. My other laptop and Desktop PC can detect it without any problem or drivers, and I have the same exact OS ( Windows 7 x64 Ultimate ) on my 3 PCs.
I have the same problem with a Game Controller (PowerPad), it works on all the PCs I've tried it on except my HP DV6c63sl. There's just my USB Mouse that works fine, and almost all other USB devices that I've tried are detected as "Unknow Device", And I've got also a "SM Bus Controller" shown in the "Device Manager window" -when I plug in my USB Game Controller- as undetected, I don't know what it is..
Here's some screens that I think they would help to identify my problem :
& Thank you very much for your help !
I really wants my Laptop to detect all the USB devices like my others PCs ( I'm talking about USB mouses, keyboards, game pads, phones with USB cables.. that get detected automatically without installing any drivers )

Hello Huntrz,
I understand you are having issues with your Windows 7 not recognising a USB device when it is plugged in. I stumbled across a thread on social.technet.microsoft.com titled USB Device Not Recognized on Windows 7 - USB mouse where they discuss a solution that resolved their issue. Now I know your mouse works, but the point is that a USB device should automatically install that is the whole purpose or USB on a computer devices are to be plug and play. Anyways, what they discuss is that what is called a Hard Reset resolved their issue. I am providing you with an HP Support document: Performing a Hard Reset or Forced Reset that will walk you through the steps to performing a Hard Reset on your Notebook.
Please re-post with the results as I am curious as well. Thank you for posting this issue on the HP Forums. Have a great day!
Please click the "Thumbs Up" on the bottom right of this post to say thank you if you appreciate the support I provide!

External hard drive stuck in keyboard USB port

Hello everyone!
Last night, I plugged in an external hard drive to perform my first TimeMachine backup on my iMac (Lion). I plugged it in the USB port of the keyboard (not wireless), but now, I can't get it out of there!! Even hubby couldn't unplug it.
Any ideas on what the problem might be? We don't want to break anything...
Thanks in advance for your help! :)

if it's stuck then one could suspect that you connected it the wrong side up but
if you did it of cause would not be seen as a driver in osx
otherwise one could suspect that the cable was somehow deform
never heard about usb devices getting soo stuck so guys like your husbond cant pull them out :S

USB port problem on Mid 2011 iMac (27")?

I have a Mid 2011 27" iMac running Lion. The USB ports seem to be resetting so that my external TimeMachinne drive disappears. I get the "disk not properly ejected" errors, but no other indicators of a problem. I tried a different usb port, same result. This doesn't seem to affect my wired keyboard, or my iPod/iPad connections (when in use).

Please do a SMC Reset.
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.

Mac Pro 2008 USB port problems - persistent

Hello all,
I have a 2008 Mac Pro - standard config : 2.8Ghz 2Go Ram ATI 2600.
At the outset I did a clean install onto a 1To Seagate drive.
From day 1, and before adding any third party applications, the aluminium keyboard would suddenly stop working. If I changed this for my old G5 plastic keyboard, I had no problem. The aluminium keyboard would work again sometimes if I changed USB port, sometimes only after rebooting.
This problem occurred randomly, a few, or many times a day.
Apple, after going thru' a number of tests with me over the phone, finally sent me a new keyboard (after having sent 2 white plastic models). This changed nothing. I then had a problem with the white plastic keyboard and one day, with a USB drive linked to a USB port I got the error message of having disconnected the disk without having ejected it first. That told me that the problem was not with the keyboard but with the USB ports (power to them?).
I did a clean install (with erase disk 1 pass) under 10.1.5 - the problem didn't go.
I then did a clean install again 10.1.5 followed immediately by upgrade 10.5.2 and the graphics upgrade. I installed no third party apps for 2 days. I had no problems. I installed some apps. No problems for 3 days. I ran all this time on a plastic keyboard. Today I plugged in the aluminium keyboard. No problems for 8 hours and suddenly tonight everythings starts over again.
I've had to do 4 reboots in the last hour. I'm back on the plastic keyboard. But if I lose that like last time I'm pretty convinced that this is a hardware issue.
Curiously I have not seen this problem cited in any forums on the Apple boards and other Mac
sites.
Any ideas ?
I wan't this machine changed. It's my work tool and I can't afford to lose so much time…nor to get so frustrated.
Apple, Help ! Please !

P.S. My first Mac was a MAC SE !!

I think there is a problem with the usb ports on the MacPro which I also think is causing some of the bluetooth problems that are being reported around. Here's why.
I have a "base" new MacPro (2xQuad 2.8, 320G drive, etc.). After getting the unit going with the standard usb keyboard and mouse I then paired my Apple wireless keyboard and mighty mouse. All worked fine. Then the problems started. I have security set that requires a log in when booting, however after restarting, or rebooting, the MacPro the wireless keyboard and mouse were no longer recognized and I was stuck at the login screen. If I then connected my original Mac usb keyboard it would not work. The ONLY way I can get the usb keyboard to work is by having it connected when I reboot/restart. Calling Apple support was...well let's just say less than useless. So I have been doing a lot of experimenting on my own. I have finally found out that if I have nothing at all connected to any of the usb ports then the MacPro will recognize my wireless keyboard and mouse (although it does take some time to recognize it). If I connect my usb devices again and reboot...back to the same situation. No connection to my bluetooth devices and my usb keyboard will not work (unless I again reboot with it already attached). Now before you say it's my other usb devices let me tell you what I have....just a Canon printer and a Western Digital USB drive that I use for Time Machine. Both of these units have been working fine for over a year and work absolutely fine when connected to my Mac Book Pro.
I believe the bluetooth device inside is connected to the usb bus internally which is why I think the usb bus is the "root" of the problem. When certain usb devices (and heck it my be almost any usb device) are attached then the usb internal hardware screws up, which kills the bluetooth connection. I believe that this problem may be borderline (not sure if its power, timing, etc.) which is why we see so many issues that are similar, but hard to pin down.
I also believe that Leopard exacerbates this problem (but not sure yet and way too long to detail now....I'm babbling enough).
Right now the only way I can get my machine to work properly is to disconnect my printer and drive, boot the machine and then reconnect them after I have logged in. That sequence seems to work.
I know that isn't any kind of an answer, but you are certainly not the only one and I think this is just another symptom of a larger Apple USB issue. I'm continuing to investigate.
Good luck all,
rd

Mac Pro USB port problem

The front USB ports on my 2010 Mac Pro aren't working. Every time I boot the Mac, I get a message window - twice - saying they were drawing too much power, and have been switched off, even though they're empty.
I've tried resetting the PRAM, powering off and unplugging everything and removing the battery from the logic board. Nothing has worked. The two front-facing FireWire ports are working, but the USB ports just won't come alive. Does anyone have any further ideas?

I would run the Apple Hardware Test:
Checking for a Hardware Problem
If you suspect a hardware problem, use the Apple Hardware Test application to help
determine if there’s a problem with one of the Mac Pro components.
To use Apple Hardware Test:
1. Disconnect all external devices from your Mac Pro, except the display, keyboard,
and mouse.
If you have an Ethernet cable connected, disconnect it.
2. Restart your Mac Pro while holding down the D key.
3. When the Apple Hardware Test chooser screen appears, select the language you
want to use.
4. Press the Return key or click the right arrow button.
5. When the Apple Hardware Test main screen appears (after about 45 seconds), follow
the onscreen instructions.
6. If Apple Hardware Test detects a problem, it displays an error code. Make a note of the
error code before pursuing support options. If Apple Hardware Test doesn’t detect a
hardware failure, the problem may be software related.
You may also consider replacing the front panel board.

Apple Keyboard USB HUB problem.

Hi, I bought this keyboard recently ( http://store.apple.com/us/product/MB...co=MTA4Mzc4ODA ), it has 2 USB ports on the side. In 1st I plugged the mouse and the other I plugged this speakers ( http://www.logitech.com/index.cfm/no...200&cl=roeu,en ). The problem is that when I'm in Windows 7 it says the hub has not energy enough to connect the devices, and the speakers do not work. Now when I'm on Mac OSX the mouse and the speakers work perfectly. Does anyone have an explanation for that?
Sorry about my english, and thank you.

well, im an idiot. disregard almost everything i just said.
Macs use EHCI/OHCI. The issue is with windows recognizing everything as low speed usb.
EHCI handles high speed usb
OHCI handles low speed usb
Windows is passing everything off to the ohci controllers whether or not they're high speed or not.
I'd still like a smarter windows usb driver, apple.

Recommendation: USB media compat with Keyboard USB port

IMac G5 20" LCD, 1GB RAM.
I need recommendations on USB memory sticks/flash drives that work connected to the USB (1.1) port on the (stock) white Apple keyboard that came with the computer.
I've done a few searches on the web, but cannot find sources that say "this works, no driver required". So I am looking for real-life people who "know" a model/brand has worked.
This is for a classroom/lab environment, so "no driver required" is a necessity.
Thanks for any/all replies to this thread.
Please send me an email as well (as I might not check this thread for a day or two).

Hi John,
Just thought I'd add that I have a SanDisk Cruzer Mini 256MB that works fine when plugged directly into the computer or a powered hub, but I also get a low power message if I try to plug it into the usb port keyboard ("The USB device cannot operate because it needs more power than is available.").
In response to your comment "a)", this isn't entirely correct. USB 2.0 can (and was designed to) work on 1.1 ports, though the transfer speed will be reduced. Curiously, I have an iPod Shuffle (which is USB 2.0) that connects with no problems to my keyboard (USB 1.1) and there is no "low power" alert. The transfer time is noticeably slower than if it's plugged directly into the computer or hub (both USB 2.0 on my computer), but it's more convenient and often fast enough for transferring small files.
If you've discovered anything with new USB flash drives I'd be interested in hearing about it. I'm considering a new one but I would like one that I can plug it into my keyboard port.
Cheers,
Matt

USB port problem: 2006 iMac

I have one of the first-gen Intel iMacs from early 2006. The USB ports seem to stop working at least once or twice a day. I'll notice that the keyboard and/or the mouse isn't responsive (sometimes it's one and not the other, sometimes it's both). If I unplug the keyboard from the USB port and plug it back in, it will start working again, but I can only do that once or twice before that trick doesn't work either. If the mouse remains unresponsive, I need to hold down the power button and restart the computer. After it reboots, everything is fine again.
I have a USB hub plugged into the other port, and switching the hub and keyboard jacks doesn't seem to make a difference. I have a pair of game controllers plugged into the hub, along with an iDevice cord (I don't typically leave my iPhone or iPod connected to it all the time) and the cord for recharging my external iDevice battery. If I switch the keyboard and hub plugs, the lights on the hub, which were on, will go off when switched to the other port, and the keyboard/mouse still won't work.
The first time this happened, I tried another keyboard/mouse combo that I knew worked, but no dice.
Oddly, the power and charging lights on the external iDevice battery light up, even though the hub port it's connected to remains dark. It's a four-port hub, and each has a blue light that goes on when power is going through it.
I ran Apple Hardware Test, the long version, but it didn't find anything wrong with the computer.
Wondering what else I can test. Could the USB ports be going bad?
It just occurred to me that this could be connected to my FireWire drives, which sometimes drop off the Finder. If I unplug them and then plug them back in, however, they come back.
I have one drive plugged into a FireWire port and a pair of daisychained drives plugged into the other one. The daisychained drives are self-powered, while the other drive plugs into the wall.
Are the USB and FireWire ports on the same board? I assume they are. Am I overloading that board? I'm wondering if I am, given everything I have connected. When the keyboard and mouse stop working, though, the hard drives remain in the Finder.
Any hints are appreciated. Thanks!

I'd recommend doing a SMC reset to see if that helps solve the problem. If you have never done one then:
_SMC RESET_
• Shut down the computer.
• Unplug the computer's power cord _and all peripherals_.
• Press and hold the power button for 5 seconds.
• Release the power button.
• Attach the computers power cable.
• Press the power button to turn on the computer.
_PRAM RESET_
• Shut down the computer.
• Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
• Turn on the computer.
• Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
• Hold the keys down until the computer restarts and you hear the startup sound for the second time.
• Release the keys.
If that doesn't solve it trying starting in Safe Mode and see if that works.

Intermittent USB port problems

I have a problem with my works Mac Pro - the USB ports on the back intermittently die, then come back!
Some problems are: An external HD connected via USB will be disconnected (the Device Removal error dialogue is displayed) then a few seconds later will remount; I will try to exit my screensaver and find that the keyboard and tablet are not working (neither the Caps Lock key light not the tablet light are illuminated), however these never come back.
I normally have to switch USB ports in the back to get a 'good' one, but it will happen once or twice a week.
I am running 10.4.10 which was a combo install with no problems, I have all drivers up-to-date and regularly run Onyx the clean everything up. Disk Utility says everything's OK and can't find evidence of a system error.
The Mac is a 2x2Ghz Dual Core Intel Xeon with 2Gb RAM. I can post the USB info from System Profiler if anyone has any clues as to what is going on.
Thanks, Lee.

Hi Thomas
I use the external HD at work and at home on my mini, but this never happens at home. The drive is mains powered. I ran TechTool on it a few weeks ago and the drive is sound, so I think the drive is ok.
Just this morning after hooking up the drive it was unmounted (just like pulling the USB cable out without ejecting) then mounted a few seconds later - the keyboard and tablet were unaffected.
The drive and keyboard & tablet problem do not occur at the same time, but the ports they use have been a problem at one time or another.
This has been happening since 10.4.8, through 10.4.9 and now in 10.4.10, but I thought I read somwhere on the Apple boards about USB port issues and now searching I can't find anything about it.
I tried resetting the PMU or SMC yesterday (inserting power supply plug while holding in the power button) and never had this happen all day... until this morning!

USB ports problem

Hi all,
I have got a brand new laptop Pavilion dv6-2060ea and have noticed problems with the usb ports. I generally use linux as a primary OS but I have noticed the same problem on Windows 7 as well. The laptop sometimes doesn't recognize usb devices as a mouse or an external harddrive, it means when I turn on the laptop boot on an OS, the mouse doesn't work and I have to reinsert it to get it work. It happens 2 or 3 times from 5 boots so it's quite often I would say. The same problem is with the external hdd, have to reinsert it and then it's all right. I have noticed that there has been a new BIOS released and this should fix some problems with usb ports but I already have upgraded to that BIOS(F.13A) and problems persist. I also miss more options in the BIOS about the CPU settings because the laptop has Core i7 and there is no any option to configure the CPU.
Be patient with my English, please. Cheers, Pepe

hello mate,
Try to check in the BIOS if the udb always on is enabled and in the boot order if the usb is not in first otherwise u could have problems to boot with something plug in...

HP 6730s - Boot & USB ports problems

Hi
I'm having some problems with my HP6730s.
1. First problem I noticed is that if I keep it running for a long period of time, 2 UBS ports (right side, near DVD drive) stop working and Windows keeps informing me about malfunctioning devices if I have any device connected to those ports. Since I usually have a wireless receiver for my Logitech connected to one of those ports, I can't get rid of the error not even if I disconnect it. The only thing that works is to turn off the laptop and remove the power cable for 30-60 minutes. This makes me think those USB ports don't get enough power.
2. I seem to be having problems when I'm trying to boot up using a Linux CD/DVD/USB. I insert the media I wan't to boot up from and I can see the DVD Drive/USB led flickering and then it stops. The Caps led starts flickering and that's it. I have to force shut down so that I can boot up again. At first I thought that it's the media I'm trying to boot up from or the BIOS settings but then I noticed that sometimes it boots up and sometimes it doesn't. I manage to boot up Ubuntu CD after 10 tryouts. openSUSE(11.xx)(the distro I need & use) is very problematic. LiveCDs won't boot up and install DVDs will simply hang on boot. If by any chance I manage to boot it up it pops out a error message and it forces me into failsafe boot/install. I also managed to install openSUSE once but it failed to auto configure videocard so I got stuck in text mode. Trying to manually install ATI drivers failed because it was unable to detect the video card. Same thing happened in Windows when I tried to upgrade the driver using the one on AMD website.
I bought the laptop in January 2009 and in December 2010 I replaced the battery.
I'm now running Windows 7 Professionas SP1 x64 up to date Also, HP Tools is up to date and I used to test the laptop for hardware issues and nothing was found. I also tested the video card and everything seamd to be fine.

I found out what's causing this but not how to fix it. I can only prevent it.
It seams that if you keep the device plugged in too much, those ports won't get enough power.
The best way to prevent this is to remove the battery when you keep the device plugged in and to also remove it when you turn it off.
I noticed this won't happen if I keep the device plugged in and ON for a long period of time but only if I keep it plugged in when turned off and if I also keep the battery inside.
But this will only fix the USB problem, not the Linux boot one.
What is you problem, exactly? Also, have you found a solution?
