Maybe. Samsung uses a few different microUSB connectors. Data and power are usually the same on all of them, but HDMI varies. If the emulator needs only a data connection, any 4-wire cable will do. (There are 2-wire cables too - like for wireless headsets - that only have power connection.) If the emulator needs HDMI or something else that Samsung does differently, it'll need the Samsung cab;e.
Try someone else's cable from their phone. If it works, buy a cheap cable. There are loads of them on eBay for under a dollar (if you're willing to wait 2 weeks for shipping from China) and for about $2 on Amazon (or your local almost anything store - dollar stores, drug stores, Walmart - everyone carries microUSB sync cables).
