I have been thinking on how to isolate a USB line. In case, USB1.1, i could use optocouplers, but USB2.0 transfer rate goes very high (480 Mbps). I probably need a transformer to isolate this line, any other idea ?
Do you know any transformers manufacturer that i could use to isolate a USB2.0 line ? Or maybe a schematic about it ?

on EDN (issue 7/672006) you can find an article about an isolated usb interface. **broken link removed**
