USB stands for universal Serial Bus, an industry-standard specification for attaching peripherals to a computer. It delivers high performance, the ability to plug in and unplug devices while the computer is running, great expandability, and a wide variety of solutions.

USB 1.1 vs USB 2.0

USB 2.0 offers a 40-times increase in speed (480Mbit/sec. theoretically) while remaining backwards compatible with USB 1.1 devices.

Can I plug in a USB 1.1 device into a USB 2.0 connection?

Plugging a USB 1.1 device into a USB 2.0 connection will not make it perform any faster. This applies to USB hubs as well. A USB 1.1 hub plugged into a USB 2.0 connection will not transform it into a USB 2.0 hub. You can upgrade a USB 1.1 interface to the USB 2.0 by purchasing a USB 2.0 adapter.

Do I need USB 2.0 or FireWire (IEEE 1394)?

If you need a high-speed interface, first consider what it is you are trying to do. If your only concern is getting digital video from your camcorder into your PC, then FireWire is the solution. If you have purchased an external CD burner that is "USB 2.0 ready" but records at a painfully slow 4x on your old USB 1.1 connection, then a USB 2.0 upgrade would be a good way to get maximum performance out of something you already own.
