| Do the Sonnet USB 2.0 or USB 3 cards support the Apple SuperDrive? | Apr-02-22 |
| None of Sonnet's Cards with USB 2.0 or USB 3 (either Type A or Type C) ports support the Apple SuperDrive. You must use a built-in USB 2.0 or 3.0 port on your Mac.
According to http://support.apple.com/kb/HT5630, "The Apple USB SuperDrive is compatible with Mac models from 2008 and later that don't have a built-in optical drive." |

| My bus-powered USB 3 drive or SSD will not reliably mount or transfer data. | Dec-14-19 |
| High power bus-powered drives are supported by the current and recent line of Sonnet USB 3 cards, plus the Tango 3.0 PCIe (FW8USB3A-E) cards, but not the discontinued USB 3.0 PCIe cards (USB3-E or USB3M-E), the initial version of the Tango 3.0 PCIe card (FWUSB3-E), or any USB 2.0 cards.
If you are still having trouble, this may be a problem due to a voltage drop in the USB cable. Use the following guide to select the correct cable for your application.
In general, these cables should work with SSDs or optical drives drawing up to 2A of current:
Type........Power-Carrying Wires....Cable Outside Diameter....Maximum Cable Length
USB 2.0..........28 AWG...............................3.8mm...........................0.15m (0.5 ft)
USB 2.0..........24 AWG...............................4.7mm...........................0.3m ( 1 ft)
USB 2.0..........22 AWG...............................5.0mm..............................1m ( 3 ft)
USB 3.0..........20 AWG...............................6.0mm..............................1m ( 3 ft)
Generally, the gauge of the power-carrying wires can be inferred from the cable outside diameter. |

| Storage connected to a USB 3 PCIe card (or Tango combo card) gives an macOS error message upon wake from sleep. | May-12-20 |
| To minimize power usage during sleep, power is removed from PCIe cards. Because of this power-saving specification, a USB 3 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. |

| How to configure Linux to use Allegro Pro USB card models USB3C-4PM-E and USB3-PRO-4P10-E | May-04-21 |
| In some computers, USB 3 devices connected to Allegro Pro USB 3 card models USB3C-4PM-E and USB3-PRO-4P10-E are not detected by Linux.
You can fix this by adding the Linux kernel parameter pci=disable_acs_redir=pci:12D8:2308 to the computer's Linux boot script. (Describing how to add a Linux kernel parameter to the computer's Linux boot script is beyond the scope of this FAQ.)
This parameter sets disable_acs_redir for PCIe devices with id 12D8:2308 (which is the PCIe bridge chip on these cards). This parameter disables PCI Express Access Control Services (ACS) functions ACS P2P Request Redirect and ACS P2P Completion Redirect. This has no effect on operation unless you are in a virtualized environment, in which case you must assign all four USB 3 ports to a single virtual machine. |
