Feature Bullets

  • Two USB Type-A connectors. Up to 10Gbps data transfer speed, twice as fast as USB 3.0.
  • Low Profile board. Include both Low Profile and Regular Size PCIe brackets. PCIe x4 card fits in any PCIe 2.0 or PCIe 3.0 x4 or x8 or x16 slot.
  • Instead of taking 5V power directly from power supply, our design includes power switching regulator circuit that automatically converts 12V from PCIe bus or from 15-Pin SATA power to ensure sufficient 5V/2A bus power on each USB port.
  • No driver installation is required on MacOS 10.9 to 10.10, and 10.12 and later (NOTE: MacOS 10.11 in-box driver doesn't support ASMedia USB 3.1), Win10/8, Server 2012 and later; Linux 2.6.31 and later. Driver download is available for 32/64 bit Windows 7/Vista, and Windows Server 2008/2003.
  • Built with ASMedia ASM1142. Fully RoHS compliant. Made in Taiwan.

 

Product Description

 
Add two SuperSpeedPlus USB 3.1 Type-A ports with up to 10Gbps data rate to your system.
 

Specification

  • Connector:
    • 2 x USB 3.1 Type-A female
    • 1 x 15-pin SATA power connector (optional connection)

 

  • Chipset: ASMedia ASM1142
  • Software:
    • No driver installation is required on MacOS 10.9 to 10.10, and 10.12 and later (NOTE: macOS 10.11 in-box driver doesn't support ASMedia USB 3.1); Win10/8, Server 2012 and later; Linux 2.6.31 and later. The OS native built-in drivers feature UASP.

 

  • Data transfer rate:
    • USB 3.1 Gen2 up to 10 Gbps
  • Power:
    • Support up to 2A/5V</b> on each USB-A downstream port.
    • The 15-pin SATA power connection is optional. Each USB port can provide up to 2A/5V power. If full loaded, it requires at least 20W (2 ports 2A/5V) power. The power supply from PCIe bus to a 4-lane/low profile card is 25W (max) per PCI Express specification.

 

  • Instead of taking 5V power directly from power supply, our design includes power switching regulator circuit that automatically converts 12V from PCIe bus and/or from 15-Pin SATA power to ensure sufficient 5V/2A bus power on each USB port.
  • Low Profile PCIe Form Factor board
  • Supports PCIe 1.0, 2.0, or PCIe 3.0 motherboard
  • Compliant with PCI Express Specification 3.0
  • Compliant with USB 3.1 Spec. Rev. 1.0, Intel xHCI Spec. 1.0.
  • Compliant with USB Attached SCSI Protocol (UASP) Specification 1.0.
  • Support USB 3.1, 3.0, 2.0, and 1.1 devices.
  • Include both Low Profile and Regular Size PCIe brackets
  • CE, FCC, and Fully RoHS compliant.

Customer FAQ

Q 1 .   Does this card support USB Attached SCSI Protocol (UASP)?
Answer: Yes, PUSB31P2A supports UASP. It is compliant with USB Attached SCSI Protocol Specification 1.0.
Q 2 .   Does each port on the PUSB31P2A have a dedicated controller or is it shared bandwidth?
Answer: It’s shared bandwidth.
Q 3 .   Is this compatible with a Mac? OSX 10.11 (El Capitan)
Answer:

It doesn’t work with Mac OS X 10.11 (El Capitan) because OS X 10.11 built-in driver does not support XHCI 1.1.

Q 4 .   Is this compatible with Mac OSX 10.12 Sierra?
Answer:

Yes, the adapter works with Mac OS X 10.12, and previous versions from 10.9 to 10.10. It does NOT work with OS X 10.11 because the built-in drivers exclude support for XHCI 1.1.

Q 5 .   What is the SATA power connector for? Does it require to be connected?
Answer:

The 15-pin SATA power connection is optional. It depends on the USB devices/applications whether to get the SATA power connected to PC power supply. Each USB port can provide up to 5V/2A power. If full loaded each USB port, it requires at least 2 (ports) * 10W (5V*2A) = 20W power. Per PCI Express specification, the power supplied from PCIe bus to a 4-lane/low profile card is 25W (max). Therefore, it should be enough for the two USB Type-A ports.

Q 6 .   How much power does PUSB31P2A draw from PCI-E bus?
Answer:
No SATA 15pin power cable connected:
PCI-e 12V / 2.1A
PCI-e 3.3V / 0.4749A
 
SATA 15pin power cable connected:
PCI-e 12V / 0A
PCI-e 3.3V / 0.4749A
