USB ports do not work with Windows 7

None of my USB ports on my Alienware laptop. I recently had the formatted hd and reinstalled the Windows 7 operating system. During the boot process any device are connected which has a power light turns on, but as soon as windows starts everything goes off. Once in windows, nothing works and I can not even my computer to recognize there is a connected device. Can someone help me?

Have you gone to the support of the computer manufacturer web site and downloaded and installed

all the updated drivers?

  • USB microphone does not work with Windows XP

    I have problems to make my USB Plantronics Gamecom headset mic works - be when the headset is plugged into USB port, or directly into the sound card. I think I checked all standard solutions: Windows OS updated, update driver for Plantronics, SB Audigy 2ZS Sound card driver updated, its mixer configured to capture a USB device to record the sound/voice and sound/voice playback (except when it is connected directly to the sound card, then I have this option is selected) , microphone not cut with setting the sound card and the "secret" on the micro iteself button is not on.

    Should there be an option to adjust microphone levels when I click "Open volume control" on the volume icon in the taskbar (lower right corner of the screen)? This option does not appear.

    Thanks for any advice you can give me!

    Norm

    Hello Norm58,

    I suggest that you install the drivers for the Plantronics device and check if it is enabled in the playback devices.

    a. Click Start, type Sound in the box to start the search.

    b. click sound in the results of search at the top of the start menu.

    c. click the Read tab.

    d. on the tab 'Read' it has listed the sound options at your disposal. It should read "The plantronics device" click on it.

    e. There should now be a checkmark on this option.

    Thank you

  • USB ports do not work in Windows 7

    Where my Windows 7 played very well a few weeks ago now, I can't access the USB ports. With a flashdrive in the port, Device Manager it says: 'a driver (service) for this device has been disabled.  Another driver can provide this functionality. (Code 32) ». I uninstalled all programs I had installed in the last 2 weeks so far. Currently, the two pilots showing with a flash drive in the USB port are: disk.sys and partmgr.sys. Could someone guide me how to activate the USB port, I can use a USB Flash drive or even external hard drive USB? Thank you

    You are welcome. Glad to see that worked.

  • El Capitan USB port does not worked well under Yosemite.

    Running a VMWARE image of the Linux kernel using a Sentinel of SafeNet USB license dongle canned.

    The USB port does not work with other USB devices?

    I suspect an incompatibility with the EC and the sine of dongle USB EL strengthened using third kexts. They must be signed, and so a softer update for the dongle is probably necessary.

    If everything is OK and right drivers all USB ports should work. You cannot install the drivers for each port separately and force one of them to work properly. On this machine, all three ports are the same USB2.0 ports.

    Try reinstalling the chipset utility.

    By the way: two other ports work well, right?
