Reading table 5-10 "High speed bulk transaction limits" and 5-5 "
High-speed isochronous Transaction limits " in the USB specification
2.0, it looks like 57,344 Megabyte/s data transfer from host to device
is feasible from a theoretical point of view. Now the practice, taking
an EZ-USB SX2 from cypress as device and a PC with a very modern
motherboard like one based on the 925X+ ICH6 + windows XP (SP2)+ no
other USB devices connected as Host, what bare transfer rates can be
achieved ? What is the processor load in such a case?

Further question, the ICH6 has 4 Enhanced USB controllers, could they
all run 60 Megabytes/sec applications in parallel? or is there a
bottleneck ?

Best Regards,
