USB port instead of I2C bus

Something like this:

Supervisor: Use USB instead of I2C
Worker: OK, I'll spend 6 months researching it and come up with nothing
Supervisor: That's what I like to hear !


or this:

Supervisor: Use USB instead of I2C
Worker: Some experienced people on the foum don't understand what you want, and neither do I.
Supervisor: You're Fired !

You can get a chip made by Philips, same mfg of the 552, that converts I2C to USB. May not offer the high speed version but it is probably your only option.

There are several 8051 derivatives with on-chip USB - use the parametric search in the Device Database on this very site.

There are also several chips available to interface USB to an 8051 (or other microcontroller of your choice)
