| One or more of my ports has stopped working on my USB 3 card. | Aug-24-22 |
| All current and recent Sonnet USB 3 cards have resettable fuses to protect the ports from an overcurrent condition. To reset the fuses, you must remove power to the card by shutting down your machine. (Restarting is not sufficient.) After turning the computer back on, the ports should start working again. If the fuses continue to trip, then you may have a device that draws too much USB Bus power (more than 2 Amps). |

| Why does Sonnet use only PCIe 2 to connect the two controllers on these 4-port USB 3.2 Gen 2 cards? | Apr-18-21 |
| We connect each USB 3 controller with two lanes of PCIe 2. Each controller has 1000MB/s bandwidth which is enough bandwidth for the fastest devices you can connect, such as USB 3.1 Gen 2 NVMe SSDs. Because the read/write bandwidth is independent, on one controller you can be reading from one SSD at 1000MB/s, and writing to another at 1000MB/s, plus the same on the 2nd controller for an aggregate transfer rate of 4000MB/s. What makes this possible is that Sonnet uses the advanced ASMedia 3142 Controller that supports Multiple INs, which means that reads can commence on one port before a write has competed on the other port.
A PCIe 3 Bridge chip would cost you $50 more, but would give you incremental performance only if you needed to continually simultaneously read--or simultaneously write--to four USB 3.1 Gen 2 NVMe devices, a very unusual use case.

| If I put a usb 2.0 and 3.0 device on the same controller will the speeds for the 3.0 device drop to 2.0 like older split-port controllers? | Dec-07-21 |
| The Sonnet Allegro USB-C and Allegro Pro 4-port Type A USB 3.2 cards support the fastest speed of each device independently on each port. The Sonnet cards supports "Multiple Ins", which means that that the host can issue a read request to one endpoint device and then proceed with other transactions without waiting for the response from the first device. Supporting Multiple Ins also improves performance to mutiple Gen 1 devices on a downstream Gen 2 hub connected to a Sonnet card Gen 2 port. |
