Leopard 10.5.6 Causes Apple Keyboard USB Devices to Lose Power While Asleep

My Apple keyboard's left usb port does not supply power to any device connected while my mac is sleeping. I have my iphone connected there to charge at night while the machine is sleeping --to save power. Before updating to 10.5.6 this was not an issue. This problem has been noted by others, but I have not yet seen a proper solution. Can anyone help?

Just want to add my name to the list. This is exactly the same thing I've experienced with my iPod Touch 2nd gen. I started noticing the battery was half gone when I left it plugged into my keyboard USB port while the iMac was in standby mode. It was always fully charged +before the 10.5.6 update+. I've now had to remember to disconnect every time my iMac enters sleep mode. Which is, of course, annoying.

Apple iPod USB Device driver issue on Win XP - syncing shuffle 2nd gen.

Hello fellow iPod shuffle users. Any of you run into this problem using the following configurations? Any advise/recommendations/workarounds much appreciated as I've burned 3 days on this issue and I'm still stonewalled.
I personally think it's a device driver issue/bug and am searching for a way to update my Apple iPod USB device driver for Win XP. Two brand new ipod shuffles (received for Christmas 2008) are both behaving this way, so the problem most likely points to a global software issue more-so than to shuffle hardware issue.
PROBLEM STATEMENT: Driver data i/o streaming issue does not allow shuffle to sync data with iTunes after initial sync (i.e. reading the content of the shuffle is good, but writing modified content fails). Posted error message "The ipod ... cannot be synced. Required disk cannot be found". After cracking the hood on my device driver, the problem seems to point to the Apple iPod USB device driver for Win XP. Driver will recognize the shuffle and read to it, but subsequent write attempts will result in device driver balks that "this device cannot start (code 10)".
ATTEMPTED WORKAROUNDS:
*Read All "How to Get Started Manuals" to make sure I was using the right technique for syncing my two shuffles from within iTunes... tried and failed
*Ensure only one shuffle was plugged in at a time (saw notice that two shuffles plugged in at the same time is not yet a supported config)... tried and failed
*The 5 R's as recommended by Apple Support... tried and failed.
*I've tried all 3 built in USB ports on my Lenovo T60. no love... tried and failed.
*Per discussion board: From Window's Device Manager-> Scaned for new hardware while shuffle was syncing...tried and failed.
* Per Discussion board: From Window's Disk Management -> Ensured shuffle came up as a FAT32 filesystem... connection tore down as quickly as windows recognized it.... tried and failed.
*From Windows Software config utility: Ran repair to re-install itunes 8... same results.
*From Windows software management utility: Uninstalled and reinstalled itunes 8... same results.
Hardware: IBM Thinkpad/Lenovo T60. Using build in k/b & no external mouse. Has 3 USB built in ports.
Software: Windows XP Pro SP2/iTunes 8.0.2/shuffle (2nd gen) driver 1.0.4 (same behavior using the original driver 1.0.3).

Hi. Ive got pretty much the same problem.... Got a new shuffle for christmas..having real problems syncing with itunes. Funnily enough I managed to get 25 tracks on it but then it just stopped. error message says " The ipod shuffle cannot be synced. The required disk cannot be found." Ive done restore, and downloaded a reset utility thingy to try but still no joy.

Apple IPod USB Device Driver Not Installed? WIndows not reconizing IPod!

Hoping someone can help me with my new Ipod Nano. I installed the IPod Updater and Itunes programs from the provided CD and formatted the Ipod. That all works fine -- the Ipod actually works, etc.
But during the actuall instation process, the Hardware Update Window came up for the 'Apple IPod USB Device' (I use Windows XP) I've tried to have it install automaticaly and manualy, without any luck. As a result, when the IPod is connected to the computer, I get a '!' on the device in Windows Explorer and neither ITunes or the Ipod Updater -- or Windows -- will reconize it!
If I connect my Ipod to the computer, the 'hardware' icon comes up in my system tray and the Ipod screen changes to the 'Do not disconnect' message. I can click on the hardware icon to 'remove' it. But I can't DO anything with the Ipod if nothing will reconize it!
I've tried updating the ITunes and Updater to the latest versions, plugged the USB cable into different spots on my computer, uninstalled and reinstalled everything, this time selecting the 'do not connect the Ipod to the computer at this time' option.....nothing. Windows just will NOT reconize the IPod and everytime I install the software I get that Hardware Update Window screen up!
Is there a driver for this I'm missing somewhere? What's going on? I can't do anything with my IPod and can't even find a phone number to call Apple for help!

This might be an issue with your operating system. You might also want to try using it on another computer before calling them as they'll probably ask you to do so. This will isolate the problem to your computer and they might tell you to try calling Windows or getting the latest drivers for your computer.

3rd gen iPod Nano will not sync with latest version of iTunes. It passes the connectivity test but not the sync test under diagnostics. Worked fine on old Windows 7 laptop but not new one. From Control Panel it shows up as an Apple iPod USB Device...

Never mind, I think. I think I figured it out. There was 1 song (out of > 900!) that somehow had been purchased with the other ID - I have no idea how. Once I deleted that song, it stopped asking.
There may be something with the newest iTunes version too. I didn't think in older versions that the "On this iPod" list of songs was greyed out. But at least it syncs ok.

Leopard failing to detect my apple keyboard

i recently bought an usb apple keyboard (the flat one).
but whenever i plug it in for the first time, leopard fails to activate it.
when i unplug it and plug it back in it'll work.
i already developed a habit to plug it in-out-in-out-in before i dare to press a key.
is there anything i can do to fix it?

must've been fixed long ago in some update, haven't experienced this issue in months

Apple keyboard USB extension lead

I bought a new Apple keyboard (one of the aluminium ones with the chiclet keys) - it's fantastic; however one problem is the recessed USB ports - fine for anything with a cable but not so good for USB flash drives as they are too "fat".
The keyboard came with what looks like a USB extension lead (so did my last Apple keyboard) but it has a strange "lug" in the female end, meaning that I can't insert any other USB devices.
Does anybody know what this is for/why it's not a standard USB connection?

The 'lug' in the USB extension cable Apple supply with keyboards is to ensure that it is only usable with Apple keyboards, since they are also 'notched' in the USB plug to fit. Quite why Apple use this non-standard connector is not at all clear. The female notch in the keyboard's USB connector means it will fit any standard USB socket, but the male lug in the extension cable means it will only accept an Apple keyboard. To me, it seems unreasonably restrictive engineering, though Apple have been doing this for years.

Apple Keyboard USB Low Power Issue

OK. I'm using a Windows machine and my G4 for a project and to save space and complexity I bought a Trendnet TK-207 USB switcher to use one keyboard, my G4's, and one mouse, a Mighty Mouse.
Both mouse and keyboard work fine powered by the HP machine but on the G4 side only the mouse works. MacOS thinks that the keyboard will draw too much current and so doesn't let it work. Since the keyboard works through the TK-207 I know that it doesn't physically draw too much but using System profiler I read that the TK-207 will supply 100mA and that the keyboard is asking for 250mA.
My question is this. Is there a way to fool MacOS into thinking that the keyboard requires less, which it does, so that I can have it plugged into the switcher all the time? Right now my work-around is to plug the keyboard directly into the G4 when I'm switched to the Mac side and to plug it back into the switcher when I'm using the HP. Not terrible but the one button push would be faster.
I've thought about buying a USB Y adapter to power the keyboard and have it inserted between the TK-207 and the keyboard. I would plug the 5V only side of the Y into a 500mA powered hub but I'm not sure MacOS would recognize that the keyboard would be getting power from another source since the data/power side of the Y would be plugged into the TK-207.
An odd situation, to be sure, but maybe someone out there knows more than I do - not really much of a stretch there. Thanks to anyone who may have an idea or could tell me that a Y adapter would work. After all, the cost of the adapter is only $15 so not much of an investment there.

I have done that. I also have tried plugging it in to a PCI USB 2.0 4-port card that according to system profiler should have 500mA available. I also have plugged it into a 7-port USB powered hub, again with 500mA/port available, with the same result, a "low power" message. It's definitely a software issue with MacOS since the keyboard works fine plugged into the kvm switch with the kvm switch getting its power from a usb port on the back of the HP computer. What I think is happening is that the embedded sofware in the kvm and the keyboard are being read by MacOS and since the kvm says it can only deliver 100mA and the hub in the keyboard says it can deliver 500mA, and the keyboard says it requires 250mA, MacOS won't let it operate. My workaround is simple, plug the keyboard directly into the built in USB port on the G4 when I'm using the Mac, but it sure would be nice to just toggle the computers using the kvm switch only.

K8N Neo Platinum, USB devices keep losing power

I have a K8N Neo Platinum with a 3000+ AMD 64 chip...
I have a USB problem whereby my wireless USB adaptor just keeps losing power, when I look at the adaptor itself all the power has gone and no lights are on. Unplugging the device and re-inserting it does not get any response from windows. Also, after this has happened, my other USB devices (ie mouse) continue to work fine UNLESS I unplug them and re-insert them. If I do this they also will not power back up. I've tried various adaptors from Netgear and alll of them have the same problems, its like they are causing the USB on my system to fail.
This happens with both the motherboard rear ports and the case front ports and is really driving me mad. Running XP Pro SP 2
I have this problem a couple years ago, and now I've gone back to using the same machine after a reformat the same is happening again. I've installed the latest nFoce drivers and in device management I've turned OFF power management for the USB Root Hubs but it's still happening.
Any ideas?

Check to see if there is a wire running from your Front USB ports to the #10 slot of your USB block which connects to the motherboard header.
USB connector block layout which corresponds to the pin layout on boards with the Intel spec for USB. Do not cut the pin on the MOBO. You are removing/cutting the wire to the connector block from the case.
2 4 6 8 10(this wire, #10, not needed)
1 3 5 7 9(filled/key)
If you find a wire leading to the #10 spot on the block, remove that wire. My block has tabs so that you can pull the wire out, or you could snip/cut the wire leading to that position--if you cut the wire, be careful to cut the correct one and cut it in such a way that it may be repaired if you make a mistake. Make sure you wrap the wire, the exposed end/s, you remove/cut with electrical tape so as not to accidentally cause a short. I actually folded the wire back and wrapped it.
2 posts to read--Here and Here.
This seems to be a common issue involving many different case manufacturers. I don't know how it applies to other MOBO manufacturers, but in these forums it is not limited to a specific MSI model or supported chipset(Intel or AMD).

USB devices keep losing power - Neo Platinum

any ideas? I'm planning to reformat and rebuild otherwise

I don't know what you mean by USB wireless adapter, but if you mean a USB wireless Hub, it could be the following: If you are plugging the Hub into a USB port on your case, the case USB wiring maybe different from your motherboard, and is grounding out your hub.
This happened to me, I have a K8 Neo Plat board in an Antec case, the USB pin configs are different; and my case ports won't work. They gound out all my USB ports if I leave them plugged into the board. I moved my self powered USB hub to a back USB port and disconnected the front USB ports from the motherboard and now it works fine.
Another reason for the problem could be that you have so many USB devices plugged into your board that you are overworking your power supply. This happened to me too. I have six ports available on the board and I'm using them all. This caused my PSU to overheat. I had to go to more power.
I don't think it's a Windows problem, unless Windows is losing track of the devices. If they show up in your Hardware Profile but still don't work, I don't think Windows is the problem and reinstalling it won't help.
But, if you have installed SP2 over XP SP1, that could be the problem. You may need to do a clean install of SP2 and then reinstall the drivers for all your USB devices. I would get the latest drivers for everything from each mftrs web site.

Prevent certain USB devices from receiving power

I need to prevent devices such as cellphones from receiving power from a USB port while at the same time allowing for other devices that we use in the enterprise to function correctly. I have been unsuccessful in my research. I would like to have this
all done on the local clients so that I can add it into the image for the enterprise. Any help is appreciated.

Hi JustIT28,
As far as I know Windows don’t have the USB device type detection ability, may you can ask your computer hardware vendor for the further help, or you can Bing
the USB security software keywords then choose some third party USB security management software.
I’m glad to be of help to you!

USB device has exceeded power limits of its hub AND no sound

Yesterday no sound, but worse...Trying to connect to computer to charge gives me the message "A USB device has exceeded the power limits of its hub power. Clicking on the balloon states "A USB device has malfunctioned & exceeded the power limits of its hub port. You should disconnect the device." Plugging into the wall charger states "This accessory is not made to work with iPhone...want to change to Airplane mode..." Is my iPhone dead? Ideas please. Thanks

Hi, Did you every get a reply? I'm having the same issue. The phone was working fine yesterday. Now, the button doesn't work and I can't sync it to restore it because I'm getting the same USB power limit message.

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.

Windows Could not find the Driver for your Apple iPod USB Device (5G 30GB)

I have a 8GB iPod Nano. My roommate has a 30GB 5G Video. Black.
My iPod syncs flawlessly. His is not recognized by Windows or iTunes. Every time we plug in the iPod, it prompts us for the driver. I tried to install the update apple mentions through the windows process, but after going through the tedious Windows Genuine Verification process, I was told that the update didn't apply to my computer.
We use a Lenovo Thinkpad T60p, which shipped with Windows Vista Business.
We are running iTunes 7.3.1.3, and there are no windows updates available for the computer.
I have...
...reset
...reinstalled 7.3.1.3 (over and over and over)
...tried different USB ports. (Early on, we saw it once after swapping ports).
...tried turning off the ability of the computer to 'Turn this device off to save power."
I have also verified that the iPod works on my work Dell Lattitude D620 running XP, and that it's not the cord, as we've used the cord that came with my Nano as well.
So, the problem seems to be with vista, as many people seem to have had. The best thread I found that deals with this was http://discussions.apple.com/thread.jspa?threadID=995793.
But even after having tried everything, I still have an unrecognizable iPod.
When I run iPod diagonostics, everything seems okay, except for the iPod connection, which says failed. I've had difficulty working with the iPod service under Computer/Device Manager - it doesn't ever seem to stop or start, with the iPod plugged in or not.
And interestingly enough, the FAT32 external harddrive that I use to back up my data exhibits exactly the same problem ("Windows could not find the driver for your USB Mass Storage Device). This device worked great in XP, and even odder, I have a FAT32 partition of the main HD as a swap space between my VistaOS and my Ubuntu installation.
Do I have to chalk this up to another issue with Windows Vista? What bothers me there is that you're a ping-pong between windows support and apple support - no one really owns up the problem.

Bill, I've been stuck in this loop for 3 months since buying a new laptop with Vista Basic. I've tried everything to no avail. I don't know what else to do apart from buying a cheap PC running XP. Let me know if you manage to find a solution and I'll do the same.
Regards. Adam

MacMini Apple Keyboard crazy at startup

I Have Mac mini Intel 10.6.8, 2.53 dual core 4g ram. Apple keyboard USB and wireless apple mouse.
At First it seemed like a broken keyboard... with keys not responding and some keys activating sporadically without my pressing.
got a new keyboard and reinstalled a clean operating system on an Erased HD, tried other usb ports.
I did all the rests for cpu and pram.
What Happens now is.
Computer boots normally and upon complete boot the number 5 presses automatically without me pressing any keys. its stops only when I press any key on the key board.
I found this out by accident. not touching anything but using the mouse and launching text editor. once text editor launched the number 5 is continuously pressed and looks like this (555555555555) non stop until i press another key. it stops until it decides to start again without warning or rational reason i could think of later on doing the same thing.
Please let me know what you think it might be and how I could fix the problem.

I did more research and as it turns out I have been Microsofted by Apple. Yes the reason I hated Microsoft has happened to me by apple. My Keyboard problems happened with the newest update of 10.6.8 and update of firmware 1.1
This really blows. ARRRGH!

Apple Keyboard used on MacBook: Some keys not working

Hello,
I use an Apple Keyboard (USB-connection, aluminium, Model No.: A1243, 2007) for typing longer texts when my MacBook is connected to an external monitor.
Since I have re-installed the OS X software on my MacBook because I had to replace the hard drive, the Keyboard doesn't work successful. Some keys just don't work; The letters cannot be typed. (Affected keys: "8", "I", "K", "," and number pad keys "7", "4", "1")
I installed all software updates for keyboards that could be found on the apple support webpages.
The keyboard istelf doesn't show any defects for me.
What can I do to solve the provlem? Or to get to know if it's a software-based problem? I want to exclude all possible software reasons.. In a worst case I have to replace the keyboard, I think. But it always worked fine and a new one can be expensive.
Thank you for all hints!

have you tried command-option and the keys? or command and one of the keys? if so did it work??? if not, try going into the finder, and go to preferences file, but did not know which one would be the culprit. The strategy I adopted, which took me back to my System 9 (and earlier) days, was to go into the Library folder of the affected user account, open up the Preferences folder (after backing it up elsewhere on the hard drive), and take out a small number of files (.plist files, etc) at a time, log out then back in and note any changes. The theory is that if there were any changes then it is most likely that the offending file was in the last group to be removed. You would then replace those files one at a time until the problem returned. Eventually I found the culprit. To my surprise it was the com.apple.loginwindow.plist file. Removing that cured things completely.
Why that particular preference file affected that particular key is beyond me, but it fixed the problem!
