If the text on the pcb says "USBasp", it is a USBasp. Version 2 is no problem, just select USBasp.
It the text on the pcb says "USBisp", it is a USBisp and not a USBasp. The name 'USBasp' in the title at Ebay is misleading in that case.
If the proper firmware is installed, it acts just like a USBasp.
But the firmware is slightly different from the real USBasp, since other pins are used.
Conclusion: Use it as if it is a USBasp. If that doesn't work (old or wrong firmware) you have bad luck and you should get rid of it.
