Is it possible to upgrade USB1.1 to USB 2.0 ?

I believe that's the same one I quoted from Apple spec above.

Just corroborating from another source...

Maybe I'm misunderstanding all the fuss but I have an iPhone 3.0 (purchased 12/08) and an iMac 800 MHZ G4 with 12MB/sec Bluetooth. They work fine together with one exception, I can't use my keyboard USB ports to connect the iPhone, I get a message that I need a USB with power so I use the USB from my iMac.

You made an iPhone 3g to work on usb1.1 ?!
Of course it's possible (Apple just disallow it), which Mac os do you use ?
Your method can be very helpful, and could even make the iPhone compatible with g3 😝

Note that the keyboard hub is on your model USB 1.0.

I didn't do anything different. I just plugged it in and it worked. I have an old iMac G4 800 MHz PPC.

Other than the iPhone 3G, I also got a iPod Nano which I got last year with USB 2.0 and works fine. The iPhone never crashed although now it's used with a new Apple laptop. The Nano I sync everyday and the only weird behavior I have observed is sometimes (1 in 20 times I sync) it gets hung up. I noticed it once when I plugged in the Nano while starting up iTunes and since then, I let iTunes start up first then plug in Nano. Can that behavior be attributed to my Mac USB 1.1? I don't know.

Here is what my profiler says I have for USB:

Hello
I want to buy an iPhone here in the UK. I believe that if I connect it to the 17" anglepoise G4 Mac I have the USB ports (both 1.1) are too slow.


Can anyone confirm this? If so, how can I upgrade the USB 1.1 to USB 2?

Thanks

I believe your questions are answered already in this topic thread.

The iMac G4s with clock speeds of 700 or 800 MHz have USB 1.1 ports.

The 15" iMac G4s with 1 GHz has USB 2.

The faster iMac G4s have USB 2.

There is no way to upgrade from USB 1.1 to USB 2.

It is definitive that you cannot upgrade or convert USB 1.1 port to USB 2.0 ... yet the motivation in many cases is to use the machine with an iPhone. I thought I was going to have to use my son's MacBook to synch, but found that I can connect just fine through the powered USB on the back. I admit that it is SLOW, but after the initial load the updates are not bad. There have been occasions when my system doesn't recognize the iPhone is connected, but I suspect that additional connections may have been the cause (card reader, ext. hard drive, tablet, ext. DVD drive).
