Överblick

PEXUSB3S25 PCI Express USB 3.0-kort med 2 portar gör det möjligt att lägga till två USB 3.0-portar till ditt PCI Express-kapabla datorsystem med en valfri LP4-strömkontakt för att ansluta till nätaggregatet och ge upp till 900 mA per port till USB 3.0-bussdrivna enheter (500 mA för USB 2.0).

Denna USB 3.0-kontroller är förstärkt med UASP-stöd (USB Attached SCSI Protocol) och är upp till 70 % snabbare än vanlig USB 3.0 vid användning med ett kabinett med UASP-stöd (Obs.: UASP stöds inte av alla operativsystem). UASP använder ett effektivare protokoll än traditionell USB BOT (Bulk-Only Transport) och optimerar överföringar genom att tillåta att flera kommandon behandlas samtidigt för att signifikant höja överföringshastigheter för kortare väntetid vid dataöverföringar. Se våra UASP-testresultat nedan för mer information.

PCIe USB 3.0-adaptern är kompatibel med USB 3.0-standarder för dataöverföringshastigheter på upp till 5 Gbps och är samtidigt bakåtkompatibel med befintliga USB 2.0/1.1-enheter. För ännu mer mångsidighet är kontrollerkortet utrustat med ett standard profilfäste och har ett fäste i lågprofil/halvhöjd för installation i datorer med liten formfaktor.

Täcks av StarTech.coms 2-årsgaranti och gratis livstidsgaranti på teknisk support.

Förbättrad prestanda med UASP

UASP stöds av Windows® 8, 8.1, Server 2012 och Linux kärna 2.6.37 eller senare. Vid tester gav UASP upp till 70 % snabbare läshastigheter och 40 % snabbare skrivhastigheter än traditionell USB 3.0 vid topprestanda.

UASP Speed Diagram

Samtidigt visade UASP-testerna på upp till 80 % reducerad åtgång av processorns resurser.

UASP Speed Diagram

Testerna utfördes med ett Intel® Ivy Bridge-system, USB 3.0-kort från StarTech.com, ett UASP-kapabelt kabinett från StarTech.com och en SATA III SSD-minne.

Vanliga frågor

Before You Buy

The USB expansion cards derive power from the PCI or PCI Express slot on the motherboard. When high-powered USB devices are connected to the USB expansion card, the power provided by the slot may not be enough to power all of the devices and you should connect additional sources of power. When you troubleshoot issues, you should connect an additional source of power.

Symptoms that you are experiencing power-related issues include certain devices not working correctly, not all of the devices working at the same time, and certain devices not working at all.

Examples of low-powered USB devices include USB mice, keyboards, and flash drives. An example of a high-powered USB device is an external hard drive that does not have an external source of power.

Installation

Prior to installing this device, ensure that your operating system is up to date (for example, you have installed the most recent service pack).

To install the driver:

  1. Download the latest drivers from the StarTech.com website (http://www.startech.com/Support). You can find the part number and product ID on the product’s packaging.

Note: Windows will typically save the files to the Downloads folder that is associated with your user account (for example, C:\Users\your_name\Downloads).

  1. Once the download is complete, right-click the zip folder that you downloaded, select Extract All, and follow the on-screen instructions.
  2. In the list of extracted files, right-click the Setup.exe file and select Run as Administrator.

Note: If the Run as Administrator option is not available, you might be attempting to run the installer from within the zipped file. Extract the files using the instructions in Step 2.

  1. Follow the on-screen prompts to install the device drivers and restart the computer when prompted.
  2. Your computer will automatically complete the driver installation and your device should be ready to use.

  1. Once the download is complete, right-click the zip folder that you downloaded, select Extract All, and follow the on-screen instructions.
  2. In the list of extracted files, double-click the Setup.exe file.
  3. Follow the on-screen prompts to install the device drivers and restart the computer when prompted.
  4. Your computer will automatically complete the driver installation and your device should be ready to use.

Hur man

To confirm that Windows detects your expansion card, complete the following:

  1. Press the Windows key+R, type devmgmt.msc, and press Enter.
  2. In Device Manager, under the appropriate heading, confirm that your expansion card is listed and that there isn't an exclamation mark next to it.  For example, a USB controller card would be under Universal Serial Bus controllers.

Your expansion card is listed according to the name of the chipset. To determine the name of the chipset of your expansion card, navigate to www.StarTech.com and look on the Technical Specifications tab for your product.

Problemsökning

If the USB device does not work after your computer has been in extended hibernation, it is likely that Windows has automatically turned off the USB Root hub to save power. 

The steps below outline how to configure the USB root hub to stay on during hibernation, to prevent this from happening.
 

Windows 10 / 8

  1. On your keyboard, press the Windows key + X and select Control Panel.
  2. Click Hardware and Sound, then click Power Options.
  3. Click Change plan settings for the plan you want to change.
  4. Click Change advanced power settings.
  5. Click the plus sign (+) next to “USB settings” and “USB selective suspend setting” to expand the options and change the setting to Disabled.
  6. Click OK to apply the setting.

Note: You may need to disconnect and re-connect your USB device after applying these settings to re-establish the connection.

Windows 7 / Vista

  1. Click the Start button and select Control Panel.
  2. Click Hardware and Sound, then click Power Options.
  3. Click Change plan settings for the plan you want to change.
  4. Click Change advanced power settings.
  5. Click the plus sign (+) next to “USB settings” and “USB selective suspend setting” to expand the options and change the setting to Disabled.

Windows XP

  1. On your desktop, right-click the My Computer icon and select Properties.
  2. Click the Device Manager tab.
  3. Expand Universal Serial Bus controllers by clicking the arrow to the left of it.
  4. Right-click the first USB Root Hub device and select Properties.
  5. Click the Power Management tab.
  6. Clear the box next to Allow the computer to turn off this device to save power.
  7. Click OK to apply the setting.
  8. Repeat steps 4-7 for any remaining devices in the Universal Serial Bus Controllers section with “Root Hub” in the name.

Note: You may need to disconnect and re-connect your USB device after applying these settings to re-establish the connection.

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:

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 from 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.
