USB appeared on Macs before Firewire did.  So, there

must be an underlying reason, already well described

by Milton, that not only did Apple go to Firewire

after USB 1.1, but they were relatively late in

adopting USB 2.0 to go along with Firewire in their

machines.


My original laptop, a PowerBook G3-400 (Bronze

keyboard), was equipped with only USB 1.1 ports.  It

never did perform as it should with accessories

attached to those ports.  The reset button on the back

of that laptop became an often-used input.


I cannot say that for Firewire 400.  It, at least for

me, has always performed flawlessly, especially if

it's compared to USB.  I cannot speak for USB 2.O

since I use Firewire 400 almost exclusively for backup

and transfer of data.  The USB 2.0 ports on my two

Macs have peripherals attached that don't really

require a high transfer rate.


I now use a iMac Intel Core 2 Duo desktop and a

similar MacBook both with owner-added enhancements

such as more memory and larger HDs.


I'm very pleased!!

Finally going to order a new DMK 21Ax04.US camera.

With my MacBook,  

does it matter if I get a USB or FireWire camera?

I'm leaning toward  

USB for resale value in a PC world.

========================

http://imjeffp.blogspot.com

I tried running a cheap Skywatcher usb camera

through Virtual PC for Mac but that was 

never very reliable and will now not re-load (I

recently had to buy a new HD for my Mac Mini 

-I always got a warning it would damage things, I

don`t know if this was the cause) and then 

a NexImage usb camera but that would not install

properly. Am in the process of buying an 

Imaging Source colour CCD! If you have Leopard you

could try Boot Camp or with Intel Macs 

VM ware...? I have my doubts about the efficacy of

usb cables- I was running 15 metres of 

inter connected cable back to my computer

inside...Again with the IS camera I hope to use a 

long Firewire cable.


I know it`s not the specialty of this site but I originally bought 4 x 5 metre lengths of 

usb extender cables and found that the length I left connected overnight quickly broke 

down and stopped working. I`m pretty sure it was a usb 2.0 cable. At least Virtual PC can 

still be used to run my NexRemote Celestron computer control!
