| 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. |

| What versions of macOS support Allegro USB 3 cards? | Apr-02-22 |
| All Sonnet Allegro (and Fusion Dual 2.5" SSD RAID) PCIe Cards use a macOS pre-installed driver.
These cards are compatible with macOS 10.10 in the MacPro 3,1; 4,1 & 5,1 and in Thunderbolt 2 Expansion chassis.
These cards are not compatible with macOS 10.11, due to a bug in the Apple driver.
These cards are compatible with macOS 10.12 (2)-10.14 in the MacPro 5,1 and in Thunderbolt 2 & 3 Expansion chassis.
These cards are compatible with macOS 10.15-macOS 12 in the 2019 Mac Pro and in Thunderbolt 2 & 3 Expansion chassis.
-------------------------------------------------------------------------------------------------------------------------
Notes:
- These cards are not compatible with Thunderbolt 1 expansion chassis.
- macOS 10.12 erroneously reports a 5Gbps connection when connected at 10Gbps.
- The maximum Apple-supported OS for the Mac Pro 3,1 and 4,1 is OS X 10.11. Dosdude1 offers patchers to allow installation of newer versions of macOS. The Apple USB 3 driver in these patched newer versions will support the Allegro cards.
- Performance of the Allegro cards may be limited by the Mac Pro 5,1 PCIe 2.0 bandwidth.

| What makes Sonnet USB 3.2 Cards more reliable than other USB 3 cards? | Apr-02-22 |
| The uniqueness of Sonnet USB 3.2 products is each USB port has a USB power switch (MOSFET) that manages and monitors the current flow of the USB port. The USB switch limits the current draw when a new USB device is connected minimizing the voltage droop of the main USB 5V power rail, thereby protecting devices connected to other USB ports from going offline because of port power droop. The USB switch is also a very effective current limiter that does not degrade over trips the way a resettable poly-fuse would. |

| 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. |
