Either way will work and yes the mRendu will handle it but less heat is better than more heat.At 9v the mRendu is already drawing ~200mA and dissipating 1.8 watts which doesn't sound like a lot but the case gets quite warm. Pulling an additional 150mA off the +5V VBUS will add an additional .6 watts or 33% more heat. More heat that isn't necessary.
In any case, I am choosing to run the uLink off it's own external DC source, a source that I already own so it's not like an additional expense.
