USB 2.0 chip recommendation?

Hi group,

I need a USB 2.0 high speed (480Mbps) controller recommendation. It 
should meet most of the following criteria:

- USB 2.0 @ 480 Mbps
- sustained data rate > 20MB/s; preferably > 30 MB/s
- parallel 8-bit or 16-bit interface
- SPI and I2C (in hardware or software)
- general-purpose I/O pins (8 or more)
- easy to use
   - minimal or no firmware required
   - drivers available for Windows and/or Linux
   - high-level API to talk to the drivers
   - good documentation and example applications
- single-chip solution; small package
- available in small quantities from major distributors

I've used the FT2232C but unfortunately it is not a high-speed device.

Thanks,
-- Georgi

Not many have single chip, small, 480Mbps solutions :

Cypress EZ-USB FX2LP (new), or older EZ-USB FX2 series.
They claim 53Mbytes/Sec

I've used the older FX2. It has 8/16 bit FIFO interface and you can use 
those pins also as GPI0. However, if I remember correcty, you can't have 
both at the same time(?) Otherwise it seems to match your wishlist quite 
well...

Depends on the package of the FX...
