Interestingly, the USB 2.x specification states that a device must not draw more than 500uA (~2.5mW) while it is not being actively addressed by the host.
I frequently wonder how many devices actually adhere to that requirement. Probably not many.

If a company claims their product is "USB compatible", but the product doesn't 100% comply with the detailed technical specification, what's the company's liability?
And if the company knew the product didn't strictly meet the USB standard, but marketed the product as "USB compatible" anyway, does that rise to the level of fraud?
1 second * 365 (number of times plugged in per year) * 500mA * 5 volts * 5 years (expected lifespan) * $0.14 ($/kWh electricity)...
Total compensation is $0.00014... Would you like a check for that?
I doubt it's likely to succeed. Everyone on the jury will be easily convinced that software is hard to get right, since they have probably used a lot of shitty software and consider it normal.
If you don't make a claim about power draw, then I suspect your consumers can't complain unless the power draw is unexpectedly large. And even then, what are the actual damages you need to compensate them for?
