In general it any combination will work. A computer with a USB 2.0 interface will work with either USB 1.x or 2.0 peripherals. A computer with a USB 1.x interface will work with USB 1.x peripherals. A computer with a USB 1.x interface fill often but not always work with USB 2.0 peripherals. Things like flash drives, card readers and harddisks will generally work, just slowly of course. CD-RW can have problems burning a disk as USB 1.1 is just fast enough to do it, not counting the overhead. I'm pretty sure DVD-RW can't burn a DVD as the data rate is just too slow. I have an EyeTV receiver that needs USB 2.0 because of the data rate. Also some things have problems with power from USB 1.x computer interfaces, such as iPods. > > ____________________________________________________________________ > > > Bruce Johnson is the expert.

On the computer both the hardware and software must support USB 2.0 in order to get USB 2.0 functionality with the peripherals. -- Clark Martin Redwood City, CA, USA Macintosh / Internet Consulting "I'm a designated driver on the Information Super Highway" -- 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.
