We are using Cables Unlimited USB-2925 USB-to-Dual-DB9 serial cables, which use the Moschip MCS7720 controller. We have downloaded the newest driver from http://www.moschip.com/mcs7720.php, but that driver was last updated in 2005. It does not seem to be working with Macs running OS X 10.6 Snow Leopard.
We have sent emails to the support addresses for both Cables Unlimited and Moschip. Cables Unlimited says they are checking with Moschip. No responses from Moschip yet.
Does anyone know of any updates for this driver, or are there any ways to get the driver to work with Snow Leopard?
