An USB ASIC miner is for a certain algorithm, not coin. If there are more coins on tat algo, you can mine them.
SHA256 is an algorithm, Bitcoin has it, some other coins too (probably Bcash and others).
Scrypt is the algorithm of Litecoin, Dogecoin and others.
As you can see, SHA256 and Scrypt are different things.
However, with such a stick you will not mine Ethereum, nor Monero, for example.
There's also something else to take into account. The network difficulty.
For example, for Bitcoin, such an USB stick may give tiny profit or (most probably) may make you lose money when running it. Such a stick needs a device (computer?) to run it so you may spend quite some money on electricity. It may be cheaper if you buy coins directly for that amount of money.
I advise you read threads like the GekkoScience's one and compare the capabilities of those with what you see on ebay.
You'll see trusted people posting stats with 0 USD/day. And probably what you'll find on ebay is older and slower.
