| After waking from sleep, my Macintosh will give me a "Device Removal" error for a USB storage device. Why? | Aug-19-09 |
| This is an issue with Mac OS X and all PCIe USB cards connected to a storage device in a Mac Pro or PowerMac G5. This applies to the USB ports in the Sonnet Tango FireWire/USB PCIe, Tango FireWire 800/USB PCIe and Allegro Express USB 2.0 cards. Sonnet has notified Apple, who has declined to address this issue at this time. |

| 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. |
