I can't imagine making any profit with a (Smaller/Cheaper) USB miner. (..?)

The gekkoscience sticks are somewhere around 15Gh/s if I remember clearly, that will not make much unless you band a few together on the same HUB.
I guess the Ant U3 (also technically a USB miner) would generate a few US cents a day but I'm not sure if that can be really listed as profit, it's miniscule.
I'm sure if you have the dollars to throw at it most to all recent ASICs are profitable, so I'm not really understanding your point on "it's the only profitable ASIC in my country"
If you really want to try make some revenue then you'll need a heavy duty USB HUB, most miners aiming this way made theirs personally. Right now, USB hubs aren't really created commonly for mining, or even being at full capacity (on most of the cheaper sells on Amazon)
I'd suggest you look for HUBs such as this, aim for the strongest though; http://www.amazon.com/Dyconn-PowerHub-10-Port-Industrial-Alumunim/dp/B00BD7L16

Good luck on your endeavour.
