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.

My apple keyboard had some problems, the store replaced it for me. I had to sign in to my computer, and couldn't get to pair the keyboard with the computer, as could not sign in. I know there is a command that lets you override this, does anyone know which buttons to press. I gather when you do this, a box comes up and pairs the two with a number you have to type in.

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 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.

Keyboard USB hub

Hello again.
Sorry I should combined this with my other thread. Oh well. Question: Is the USB hub on the keyboard supposed to be the same speed as the ports directly on the back? I was having all kinds of problems with my Creative Nomad ZEN until I plugged it into the back on the computer. Before i was getting like 6mbps transfer. With it in the back I got like 45mbps, which I was very pleased with.
So yeah, is that an indication that I need a new keyboard?
Thanks Again peeps,
Jesse

Ah, yes! That is what I thought!
thanks for the help

Keyboard/USB connection problem.

Couple of weeks ago my aluminum keyboard intermittently stopped responding to my touch. I unplugged/replugged into a different USB port on my Mini which seemed to fix it a couple of times, then shut down computer and restarted a couple of times which worked for a bit, than i started getting this message:
A USB device is currently drawing too much power. The hub it is attached to will be deactivated.
I started using my old keyboard and everything was fine until today when it stopped responding. Doing the same things as last time but haven't gotten the warning message, YET.

Sorry--keyboard went out again before I finished previous post. Somewhere it was suggested that I get a USB hub which runs on a separate power supply. Before I attempt that remedy, any comments, suggestions?

PPC Update 10.4.7 and USB hub problems

Hi,
After installing the PPC 10.4.7 combo update on my PowerPC G5 dual 2.7 GHz (4GB RAM) I have problems with my USB hub. The update seemed to have been installed properly (two reboots and no error messages) but since then my Kensington track ball does no longer work after power on. I have to detach and reattach the USB hub to reactivate the trackball. The problem does not occur after a restart (only after a power off/on cycle).
The USB hub did work before the update and I did not change the configuration after the update.
I hope someone can help me with this as it is very frustrating for me to crawl under my desk to detach and reattach the USB hub every time I turn on my mac...
Thanks for any help!

I can't help you, but I wanted to say that I have a similar problem. After a sleep/wake, my hub doesn't wake up. I have done a bunch of troubleshooting, including buying a new hub, which did not solve the problem (I took it back). When I reboot, all is back to normal. I have a 2001 Powermac G4 with a Sonnet Allegro USB 2.0 card that I added, over a year ago. It has worked fine since I bought it. Now, after upgrading to OS 10.4.7, I have this sleep/wake problem with the USB hub (Keyspan).
I have checked the ports on the USB card and I have found that at least one port is dead when I wake the machine back up. I can switch over devices around and they work in the remaining three ports on the board. The hub, however, does not work at all in any port, until after a reboot. There must be some special signal that the board sends out to the hub that resets it after a boot. I don't know. It's very frustrating, though. I don't like waiting for a reboot, which is why I have gotten in the habit of using sleep.
Maybe someone else has some idea what might be causing this problem? It could be just a coincidence that it started soon after the OS update. Maybe the board just decided to go bad at this particular time...?

Hi,
you may try skipping the system check and check if that may bypass the problem,
When the System Requirements Check window appears, click on the Cancel button while holding the Ctrl+Shift keys. This will bypass the sys. req. check and continue the installation. You may need to do this several times for the installation to proceed.
If that doesn't help I would recomemnd ensuring that you have the latest USB drivers for your PC, please clarify your PC model and I would try pointing you further as possible.

External HD + Airport Extreme + USB Hub = Problems

I'm having issues connecting my 2 external HDs to my airport extreme via USB Hub. I have a My Book 1TB HD and a 500G Maxtor OneTouch that I connected to a powered usb hub that is plugged into my Airport Extreme. It works for a minute, I can connect wirelessly to both, then it hangs up and fails to mount. When I disconnected it all and plug one of the two into the Airport Extreme, it works flawlessly. I want to use the 1TB for all my goodies and the 500G for my Time Machine Backups.
I guess my questions are these:
1. Is the USB Hub not supplying enough power or could it be that the USB Hub just cannot handle two HDs. (Its a rocketfish powered usb hub btw)
2. What four port powered usb hub would you recommed me using to connect the 1TB and 500G external HDs to my Airport Extreme?
Thank you in advance!

I am having a smiler issue i have a 1TB WD hard Drive plugged into the USB hub on my Airport Extreme. When it mounts it works great...I use it to access all of my music. The problem is it gets disconnected constantly and when it does it also takes out my Airport Express. I have to unplug the Extreme to reset it all.
Any help would be appreciated!!

USB Hub problem?

Hi,
I have a USB hub, 7ports / USB 2.0/1.1 powered by a mains adaptor.
I am connecting 1 x USB 3 external drive 750 GB (partitioned into two sections) and 1 x USB 2 500 GB external drive. I use these for mixture of storage and backup, and exchange data between them.
Both drives work perfectly well when I connect one at a time (the USB 3 is always connected at startup) but when I insert the USB 2 device into the hub, the first devive (USB 3 partitioned) disconnects and I get the standard warning " disc was not ejected properly" etc. etc.
(I know the MacBook has 2 x USB inserts, but one is connected permanently to an audio capture device - non negotiable)!
Would this be because the hub is not suitable for USB 3 devices, or some other reason. Any advice would be greatly appreciated!
Many Thanks............Brian

My suspicion is that the hub doesn't provide enough power for both drives. Check the specs (power or current consumption) for the drives and the hub. Keep in mind that, often enough, especially on cheaper hubs, the power supply ratings are wildly optimistic. Eg, the power supply may be rated for 1A, but effectively delivers only 0.8A; if each drive needs 0.5A, connecting both at the same time won't work.

New Keyboard (usb hub question)

Aloha, before I buy the new keyboard, I would like someone with real world experience to tell me that the usb 2 hubs on the keyboard actually work, or is that just an Apple marketing ploy ? Will plugging in an iPod, or some other "power hungry" device really work? Mahalo in advance for any facts, info. JB

The webpage for the new keyboards contains the following regarding the wired keyboard:
"Two USB 2.0 ports provide high-speed connectivity for your iPod, Mighty Mouse, digital camera, and other USB-based electronic devices. Yes, we did think of everything."
I'm not sure what to make of this. I have a small external hardrive that worked initially with the keyboard ports, but it no longer works. The ports on a replacement keyboard that I received do not work either. The folks at Apple Care seem to think that many of these devices will not work with the keyboard, but they also seem to be surprised when I point out what the website says. It does sound like the marketing department needs to talk with the tech folks.
I'll try it with my wife's ipod, but it seems like the keyboards are not functioning they way they have been advertised to work.

Apple keyboard with numberpad problem

I have been using the usb keyboard (http://liss-mug.org.uk/sites/default/files/images/apple-qwerty_red_570.png) for my macbook pro for around 10-11 months and today keys 0 p P ; / are not working (but using the macbook pro keyboard is fine). I want to know how to fix the problem with the kyboard.

Some problems users have had with the wireless keyboards, and one had a USB keyboard, were resolved by unpairing/disconnecting. Then removing batteries in the wireless, and start pressing keys randomly, swiping the flat of the hand over the keyboard for several minutes. Then reconnect and the keyboards would usually work. Seems the capacitance switches that are now used instead of mechanical switches had to be discharged.
So, try that trick and see if it works. If not, there is probably a hardware fault in the keyboard.

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.

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!

Re: Problems with USB hub in Studio Display

Ok, so I read a couple of posts here about USB hub problems with studio displays. Well... lucky me. I just got a used 17" studio LCD from craigslist.com (a local person) only to discover a day after getting it that it abruptly tries to go to sleep on its own; or the usb hubs in the back stopped responding; and/or it would intermittently flicker on and off like it was trying to go to sleep but couldn't. The screen itself is perfectly fine and clear when its own and I can get it to stay on for awhile with no problems, but just from my impression from the thing, this problem is going to continue. Was there ever a reasonable solution for this USB issue? My computer was running fine before on a 17" CRT Studio Display. And unfortunately, I've already given that one away.
<--- Poor student, so I'm hoping I'm not SOL.

Is your USB hub a self-powered one? Meaning, does it have its own external power supply?
If it is, make sure its power supply is plugged in to a live source. Also, some self-powered hubs have a small selector switch, allowing the choice of bus or self power; if it has such a switch, be sure it is not set to "bus".
