Same problem here, since my upgrade to SL 10.6.1 five days ago, my MC950D Ovation USB Modem doesn't work. I did download the 2.2.3 driver and the modem still doesn't work. My wireless service provider has no answers to why and the only answer that I got from Rogers Wireless technical support was " the Ovation MC950D does not work with Snow Leopard. " Great help, I knew that before I call them.
Does anyone out there have any suggestions ? Please, help.
