Isolating USB2.0 line

[System.out]

Hello,

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 ?

Regards
