RB, generic cables will work providing you have a cable with the right connectors. I think what you are looking for is a USB mini -> USB cable which can be purchased at Radioshack. I advise bringing the device with you to ensure the connector works.
I browsed their collection of USB connectors in the POS branch while attempting to find a similar cable for my portable laptop drive. Their variety is impressive however their pricing could be better, the gold plating on the ones i got was nice although not necessary.
