No. It will run at the slower USB 2.0 speed. Whenever you are working with devices that work at different speeds your bottleneck will always be the slower device.

RE: weird USB - Firewire bridge
I one got something similar in a set of USB adapters. In my case, the kit came with a retractable USB A male-to-A female adapter (extension cable) and a set of various adapters to convert the extension cable into a dedicated purpose cable; this included a pair of RJ-45 ends to turn the cable into an Ethernet cable. I think there was supposed to be a complementary adapter to the one your father has in order to allow a USB extension cable to be used as a 4-pin FW400 cable. (Ironically, I think you have the mate to the one I used to have- USB female-to-mini FW400.

These are a PITA necessity now that Apple has dropped FW from some machines. The adapter is so small that I really can't imagine what kind of electronics is hidden there! I always thought Firewire required a special controller, and that's why Firewire devices were more expensive than their USB counterparts. A real firewire controller does the i/o work for the CPU. The protocol's low overhead, plus the work done in the controller, are the reason for FW's blazing throughput. USB is designed to be a cheap dumb interface - making the main CPU do most of the work. The adapter converts the signals but does no processing. That's up to your USB driver and the machine's main CPU to do. I can post links to some images of the adapter, but I wanted to know your opinion prior to plugging something to it. Will it blow up? :) It should be fine. Just don't expect full firewire performance from it. And I believe the Adapter counts as a "device", so it pulls a "unit" of power. This can be problematic with some peripherals that want to leech power from the bus -- USB has much less power available than FW. If this is a problem, you'll get a dialog complaining. If it's a serious / electrical problem, OS X will shut off the interface (reboot to restore it). A powered hub will usually fix things.

It might stop working after a while, but it won't blow up. This is what usually happens to really cheap computer stuff. -- Sent from my Power mac G4 Sawtooth. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
