Dear experts,

What would be the limit of USB output?  I know IEC 60950-1 requires only that 
it complies with limited power source, but there might be some other 
requirements to limit power from USB?

In particular, I am talking about power supply with USB connector. Can it go up 
to 5Vd.c./3A?

Best regards,
Bostjan Glavic
