756 Do the Sonnet USB 2.0 or USB 3.0 cards support the Apple SuperDrive?May-27-15
Sonnet's Allegro Pro USB 3.0 PCIe (USB3-PRO-4PM-E), Allegro USB 3.0 4-Port PCIe (USB3-4PM-E), and Tango 3.0 PCIe (FW8USB3A-E) cards support the Apple Super Drive, with the installation of the Sonnet USB 3.0 Power Kernel Extension on systems running OS X 10.9 and later.

Sonnet's USB 2.0 PCIe cards, Allegro USB 3.0 PCIe card (USB3M-E), Tango 3.0 PCIe card (FW8USB3-E), and USB 2.0/3.0 ExpressCards are not compatible with the Apple SuperDrive.

According to, "MacPro (Mid-2012 and earlier) and MacBook Pro (pre-Retina) computers are not compatible with either the Apple USB SuperDrive or the MacBook Air SuperDrive."
759 When connected to the Allegro Pro USB 3.0 PCIe, Allegro USB 3.0 4-Port PCIe, Tango 3.0 PCIe, or Tempo Duo PCIe card, my bus-powered USB 2.0 or 3.0 drive or SSD will not reliably mount or transfer data.Jun-24-15
817 USB storage connected to a PCIe USB 2.0, 3.0, 3.1 card (or combo card) gives an macOS error message upon wake from sleep.Dec-02-17
To minimize power usage during sleep, power is removed from PCIe cards. Because of this power-saving specification, a USB 2.0, 3.0, or 3.1 PCIe card is unable to maintain USB port power during sleep. In macOS, this result in a storage device disconnect upon wake from sleep. The storage device will automatically remount, but the system reports a disconnect message. Because macOS flushes all caches before sleeping, this disconnect should never result in any loss of data.
