does that not put a hit on CPU? A significant hit?
Thank you.
Thank you.
Ah! Thank you. I suppose that it's safe to assume that an interface like the Scarlett, which has an external power supply, requires more juice than the bus can supply.
That's most likely the case.
A computer's power supply can be also be noisy and many interface designers prefer to control the quality of the power by using a non-bus powered supply.

Although the USB standard states that 5VDC at 500mA will be available on the bus, this is not always guaranteed in practice. Some chip-sets do not seem to provide the full current rating. For that reason, some form of external powering is useful.
