Content preview: Dear Mike, LF Group, I am not an expert on the subject but... USB 2.0 is an update on USB 1.1. The main difference is that USB 2.0 defines a high speed 480 Mbit/s mode in addition to the 12 Mbit/s full bandwidth and 1.5 Mbit/s low bandwidth modes allowed by USB 1.1. But a USB peripheral does not have to use the high speed mode to comply with USB 2.0, and the USB 2.0 device should automatically configure itself to work at a "backwards compatible" lower speed where possible. 12Mbit/s should be enough to cope with the output of a sound card, since 48k samples x 16 bits/sample x 2 channels is a little over 1.5 Mbit/s, but I guess it depends on how the sound card makers have designed their product - so you will have to plug it in to find out!

A problem you may well have is finding a suitable driver for a new sound card that will run under an older operating system on your old laptop - the manufacturers often won't bother writing new drivers for Win2k and older operating systems, XP and later usually seem to be supported.
