I'm thinking of creating a USB decoration device - Wii "sensor" bar - and I've calculated that for 8 IR LEDs (2 x 4 in series, with the two groups in parallel) that I would need 250mA @ 5V. Since USB initially provides only 100mA, I'm thinking of using AVRUSB to request more amperage. Now I'm wondering if I do request more current, would it damage the AVR? Oh, and how much current does a typical AVR require?

Thanks.
