I have purchased a Plugable USB2-CARDRAM3. When plugged into a USB 2 port, the device does show up in Device Manager in Windows 8.1 Pro-64, with a yellow exclamation mark. Windows throws an error that says: “The drivers for this device are not installed. (Code28) There are no compatible drivers for this device. To find a driver for this device, click Update Driver.” When I click Update Driver, it searches and tells me there are no drivers available.
