| Does the Allegro USB 3.0 card support bus-powered drives?
| Nov-27-13 |
| The Allegro USB 3.0 card does not provide enough power for most USB 3.0 2.5" bus-powered drives and SSDs.
The Allegro USB 3.0 card powers bus-powered thumb drives just fine during wake, but does not have power for any bus-powered drives during sleep. In a Mac Pro, bus-powered drives will disconnect upon wake and need to be unplugged and plugged after sleep to reappear on the desktop. In a Windows machine, the drives appear normally after sleep. Wall powered drives do not have any issues with sleep in any machine. |

| 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. |
