Maybe it depends on what is plugged in. As with my PC at work, my classic iPod won't worked plugged into my wife's keyboard with her mouse on her iMac. I haven't tried it on my iMac, which is a year newer and has the aluminum keyboard. There are two elements in how this works - each device uses up a constant voltage, and some products use more power than others.

Does your wife have the aluminum keyboard? And what kind of iMac does she have?
 
USB Developer's Note

iMac Computers (April 2008)

The iMac computers introduced in April 2008, based on the Intel Core 2 Duo processor on 45 nm process technology, have multiple internal USB 2.0 controllers built into the South Bridge. The controllers support three external USB ports, the built-in iSight camera, Bluetooth +EDR, and the IR receiver. Four ports are not used.

The external USB ports comply with the Universal Serial Bus Specification 2.0. High-speed USB devices are accessed via the Enhanced Host Controller Interface (EHCI) and full-speed and low-speed devices are accessed via the Universal Host Controller Interface (UHCI).

A single high-powered device can be attached directly to the external ports, and software will enable one of its downstream ports to supply 500 mA of power. If a second high-powered device is attached, it will behave like a normal bus-powered hub and only provide 100 mA per downstream port.


iMac Computers (August 2007)

The iMac Computers introduced in August 2007, based on the Intel Core 2 Duo microprocessor, has multiple internal USB 2.0 controllers built into the South Bridge. The controllers support three external USB ports, the built-in iSight camera, Bluetooth +EDR, and the IR receiver. Four ports are not used.

The external USB ports comply with the Universal Serial Bus Specification 2.0. High-speed USB devices are accessed via the Enhanced Host Controller Interface (EHCI) and full-speed and low-speed devices are accessed via the Universal Host Controller Interface (UHCI).

A single high-powered Apple keyboard can be attached directly to the external ports, and software will enable one of its downstream ports to supply 500 mA of power. If a second high-powered Apple keyboard is attached, it will behave like a normal bus-powered hub and only provide 100 mA per downstream port.


What's happening with USB power on the iMac?

Back on the iMac G5, each of the three USB ports could supply 500mA - plenty for any bus-powered device, and enough to allow the connection of an unpowered hub with multiple devices that only require the normal 100mA or less.

Fast forward to the "April 2008" iMacs, and things have changed. There are still three USB ports, but only one of them can be used as a high-power port at any given time (source: iMac Developer Note, Apple).

So if you upgrade to the new model, you may find that your old set of peripherals may not work correctly without the addition of a powered hub. This is especially likely to affect devices such as bus-powered hard drives (including iPods) and cameras, or configurations with multiple low-power devices connected via an unpowered hub.
 
Does your wife have the aluminum keyboard? And what kind of iMac does she have?

We both have 24" iMacs. Mine is the first model with the aluminum keyboard, hers is the last one without it. I don't care for either keyboard, they don't feel right to this touch typist.

I tend to doubt if there is any difference though as far as how they work as unpowered USB hubs. Each device uses some power that has to come from the original USB port.

According to the Apple developer info I posted above, the difference with the iMac and the Apple aluminum keyboard is one of the ports on the keyboard can supply 500ma of power while the other keyboard will still supply 100ma. This isn't how a typical passive hub behaves.

This is done through software.

A different keyboard might not allow this behavior.
 
Which is a lot when you only have 512 MB to deal with.

I haven't, nor do I plan to upgrade from iTunes 8 until it's absolutely necessary. My eMac is struggling with 8 already, it doesn't need any more bloat. :rolleyes:

I have 2 GB, what's the point? :confused:

Unless you mean your own computer. ;)
 
I follow you on the App Store related issues. Seems to me that iTunes crashes every third-time I open iTunes Store. Updating Apps results in various, assundry problems and pop-ups.

Otherwise, RAM and speed are acceptable.
 
iTunes Screwing Up?

Hi, I just did a clean install of OS X Snow Leopard. Updated. Then started installing stuff, adding music, etc. Put music into iTunes, which is on my external hard drive and plays off of the external. My music skips (when it didn't before, ever) and my album art is screwed up. Some get loaded correctly, others only get loaded partially and the rest is black.

Anyone else having this problem and find a fix?
 
The interface for the "new and improved" itunes store is absolute rubbish: The columns are so narrow that only a few words fit in the first column, and you cannot resize the columns. If there are 20 versions of a song by the same artist, it is very very difficult to find out what version of the song you're looking at. It's absolutely horrible. And hovering the mouse over the name of the song only very occasionally shows more information about the song. After buying 10 songs I didn't really want, I stopped using it.

I have wondered if they did this on purpose so they could get more sales out of people buying the wrong songs.
 
no more youtube downloads?

i used to pull youtube videos into mp4 format, then via itunes, load them to my iphone, no more. now i get some cheesy message about it being a proper file format or such, LAME!

how do i uninstall iTunes 9!!!????

:rolleyes:
iTunes is not blocking your youtube videos. You're converting them wrong, or youtube changed something to attempt to block you from taking their content.
 
A simple Music Library app should take half as long as Safari to open. It doesn't. I'm running iTunes 9 on a current generation Macbook Pro and it feels slower than it should. I shouldn't notice any lag, and pictures should scroll smoothly and load instantly without me ever seeing a black placeholder box.

Maybe I just have too high of hopes.

Define simple? Your definition could be very different from mine and others.

If you mean by simple: 250 gigs of music, 1.6 terabytes of movies and 7 pages of apps on the iphone. Then yes that is simple for me. Zero issues. Cover flow works great no lag times.

Are we measuring our ePenises? I'm just saying something as simple as a media player shouldn't take anymore time to open than Address Book or Safari. iTunes has become bloated. iTunes' bloat has nothing to do with how big your library is.

Oh, and... you're super cool because you have such a big library. :rolleyes:

It has become somewhat bloated, but iTunes is able to do more things now than it ever has, and also on the other side of the coin, after it is actually loaded, it takes a shorter amount of time in most cases to do the same things as earlier versions. It's just the initial loading time that sort-of bites.

They REALLY need to fix the problem with the column width in the iTunes Store.

Get a Solid-STate Disk Drive. Problem solved.

Or, for now, select "open at login" and iTunes will boot up when your laptop boots up. Loading time will be less noticeable since you're already waiting for the computer to boot up.

I doubt it gets as fast as Address Book. Address book is just a text reading program for the most program.

Safari doesn't have to load much and actually I don't think Safari loads that fast either.

I know you could get a faster-loading music playing program, but you'll have to give up some of the artwork and the database functionality which let you quickly find a song, make playlists and organize your music etc.

I have a desktop so I'm not starting and stopping iTunes too often. I can see it being more of a beef on laptops. Maybe they could have an iTunes lite that is just a player or something. My biggest beef is I'd rather shop iTunes in the browser than in iTunes itself. That and the iTunes buttons and scroll bars (much like OS/X) are too tiny.
 
Why iTunes 9 is pissing me off...

Ok, this might be more of an early/mid-2009 iMac problem (at least that's what most of the other complainers on the Apple support forums seem to have) -- but what's the deal with iTunes randomly deciding to play music? I have it paused and in the background, and all the sudden music starts playing... friggin' annoying!
 
I use iTunes 9 in windows. Current version 9.0.2.25, and it is horrible as hell. Not like it hasn't been in horrible windows but this version just tips the scales of horrible. Launching from the startmenu makes my start menu freeze up for at least 15-30 seconds, the program takes forever to launch, deleting a song leaves a gap in the library list to which the only remedy is to restart iTunes to get rid of the void in the list... incredible. At least iTunes dosen't randomly pause for me anymore when not doing something WITH itunes, instead it runs even ******* when i'm changing songs or launching the damn thing.
:mad::mad::mad:

I HAVE to use iTunes in windows because I want music when I'm playing games...and we all know OSX dosent have too many games.
