Where to buy

The ECUSB3S254F 2-Port Flush Mount USB 3.0 ExpressCard Adapter lets you add two USB 3.0 ports to your ExpressCard-enabled laptop.

The USB 3.0 card uses a unique design that allows it to sit flush in a standard 54mm laptop ExpressCard slot, creating a seamless add-on that can be left installed even while on the move, without having to worry about impact damage to either the card or the ExpressCard slot.

Enhanced with UASP support (USB Attached SCSI Protocol), this USB 3.0 controller performs up to 70% faster than conventional USB 3.0 when paired with a UASP supported enclosure (Note: UASP requires a compatible operating system). Using a more efficient protocol than the traditional USB BOT (Bulk-Only Transport), UASP technology optimizes transfers by allowing multiple commands to be processed simultaneously, significantly increasing transfer speeds for less wait time on data transfers. See our UASP test results below for further details.

The SuperSpeed USB 3.0 Card supports data transfer rates of up to 5Gbps, and is backward compatible with USB 2.0 (at up to 480Mbps), or USB 1.1/1.0 at up to 1.5/1.2 Mbps respectively - the perfect laptop accessory for users to connect USB devices, both new and old.

Backed by a StarTech.com 2-year warranty and free lifetime technical support.

Improved Performance with UASP

UASP is supported in Windows® 8 and Server 2012. In testing UASP performed with up to a 70% faster read / 40% faster write speed over traditional USB 3.0 at peak performance.

UASP Speed Diagram

At the same peak in testing, UASP also showed up to an 80% reduction in required processor resources.

UASP Speed Diagram

Test results were obtained using an Intel® Ivy Bridge system, StarTech.com add-on USB 3.0 cards, a UASP-enabled StarTech.com enclosure, and a SATA III solid state drive.

Applications

  • Users who need USB connectivity, but do not need to swap between other ExpressCard adapters, so will leave the card installed in the card slot
  • Mobile users who want to leave ExpressCard adapters installed, without worry about damaging the card or slot while on the move
  • Connect high performance USB 3.0 external storage devices to a laptop
  • Upgrade an older laptop with USB 3.0 connectivity
  • Expand on your laptop expansion capabilities with additional USB ports

The StarTech.com Advantage

  • Eliminate the worry of snagging or hitting the ExpressCard with a unique Flush Mount design
  • SuperSpeed USB 3.0 connectivity at up to 5 Gbps, while still backwards compatible with USB 2.0/1.x
  • Time-saving file transfers, up to 70% faster than traditional USB 3.0 when used with a UASP-supported enclosure

Frequently Asked Questions

Troubleshooting

You should not upgrade your device's firmware if you do not have any issues with the functionality of your device. The only time you should consider an upgrade is if you are experiencing a problem with the device, and you have confirmed that the firmware addresses this problem.  You can confirm this is the case by reviewing the documentation included with the firmware or by consulting with our Technical Support team. Incorrectly upgrading firmware can result in diminished performance so it is best to contact StarTech.com if you would like to perform this operation.

When you troubleshoot issues with a USB controller card, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

  • USB cables

  • USB devices

  • USB controller card

To test your setup components, try the following:

  • Use the USB cable, device, and controller card in another setup to see if the problem is with the components or the setup.

  • Use a different USB cable, device, and controller card in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test your cables, it is recommended that you do the following:

  • Test each cable individually.

  • Use short cables when you are testing.

When you test the USB device and controller card, it is recommended that you do the following:

Good add on for an older laptop

By: Lizard_king - 10-14-2015
I just received this earlier and it installed without issues using the drivers i took down from Startech. The speed is noticeably faster than the USB 2.0 ports and makes using this card a good choice.

Very slow!

This card's USB 3.0 port transmits data slower than PC's USB 2.0 port.

Hello Aleksandr, Thanks for sharing your review with us. There are a lot of factors that could be affecting the speed you are seeing when using this card, such as; - The model of your laptop and if has Gen 1 or Gen 2 ExpressCard/PCIe slots. - If you are using the best and most up to date drivers for this card and chipset of your PC. - Up to date BIOS. Other factors can affect speeds as well depending on your setup. For further information, you can always speak with our technical advisors by clicking the "Support" tab on our site. Thank you, Barry Customer Support StarTech.com

Works, but has issues.

By: BobtheEngineer - 09-13-2018
Driver installation was difficult. If you purchase more than one of these cards, interchanging them across different PCs wont work. Each card comes with an accompanying CD and you MUST install it's paired CD on your computer to use it. This seems to be a very sloppy method to install product drivers. The unit once installed properly does function as a set of two USB 3.0 ports. I use it to interact with a USB monitor adapter and have not had any issues for 2+ years running. The external jack seems to be broken as I was trying to run a USB3 vision camera with this card and did not have any luck. This was when I wired the external power cable to a phone charger for power. External jack is broken? All in all this product works, but it has its hiccups.

not so happy would like some help trouble shooting

By: Leonardo93 - 04-27-2020
so it was working perfectly. I had installed the correspondant ECUSB3S254F driver coming in the CD and after a while it didn't recognize any more my external hard drives. I can plug usb sticks and everithing looks normal but with my external hard drives are not recognized any longer. Once I had this problm in the past and I've resolved it just by installing the driver again. Not this time. Quite dissapointing

Excellent Quality! Works Very Well and Quickly!

By: William G - 05-31-2020
I bought this for my old Dell Latitude E6400 laptop to transfer a lot of files to a portable drive, and it preformed awesome just as Startech said it would. I was very impressed with the USB 3.0 speed. It was very easy to install, and it even came with a CD that had the needed drivers, so it only took a few minutes until I was transferring all those files at lightning speed. Before buying it, all my questions were expertly answered by a representative with Startech’s chat service. Thank you for such a great product! : )

Plug n Play On Linux

By: PeterThePlumber - 07-26-2020
I use this to add usb ports to a Toughbook CF-19 Mk7 that I use in my cobbled together home office. I plugged it in to the Expresscard slot and it worked out of the box. I did not use the driver CD because I used Linux and those would be of no use to me. And yes, the cover closes and seals with the adapter in place. I can't speak to transfer speeds, because I'm using it to connect external keyboard, webcam, mouse, etc. For my use it works flawlessly.
