Driver for USB digital speaker?

Last time I bought a set of digital USB speaker (...Pleomax PSP-7000W/Christal Edition). The description on the packing up was clear: Compatible with Microsoft Windows,..... and Mac 10.1 or later, driver disc included. When I wanted to install the driver, I found out, that there is only software for windows on the CD!!!
The support of Pleomax/Samsung does not answer me. Is there anyone with an idea, if there are drivers for Mac - and how I can get them?
