The common connection appears to be -ve so the driver to R,G,B needs to "source" current, not "sink" current. I don't know specifics of which drivers (brand, model) can do this. Cheap 5v ones I have been working with are opposite (+ common).

You will need driver which can supply enough current on each channel, for device you are driving. BTW what specifically is this device, RGB LED strip?

Yes but there are different types. Some use power/data interface for serial daisy-chain LEDs. OP's looks like direct drive to each LED colour; and there is the drive polarity I mentioned. Web search shows hundreds of different ones.

Perhaps OP can give us a few more details. RGB controllers I see online are mostly (R G B +) not (R G B -) configuration so would not work.
