donut 62 Posted September 23, 2014 Report Share Posted September 23, 2014 Hi there, We'd like to help you with the issue. Did you do some operation for your PC before all the USB ports are dead. Thanks! Link to post Share on other sites
knurk 1 Posted September 25, 2014 Author Report Share Posted September 25, 2014 Using DriverMax/DriverBooster, I had been updating a number of drivers. Strangely, all USB drivers are working correctly, and diagnostic tests find nothing wrong. Link to post Share on other sites

Strangely, all USB drivers are working correctly, and diagnostic tests find nothing wrong. Roll back any/all new drivers that were installed (to the ones you had before) and retest. knurk 1 Link to post Share on other sites
knurk 1 Posted September 26, 2014 Author Report Share Posted September 26, 2014 Hi, all rollback buttons are greyed out. I have tried update driver-buttons, and 1 port USD 2.0 started working for memory sticks and external hard disk, and charging the phone, but not for the mouse. My two 3.0 ports are not yet working, when trying to update, the message is: you already have the best driver. Restarting made no difference... UCanFixIt 1 Link to post Share on other sites
UCanFixIt 339 Posted September 26, 2014 Report Share Posted September 26, 2014 Hi knurk, FYI, Drivemax has corrupted many devices so please stop using it to prevent further issues. Did you try using the rollback feature provided with Drivemax? If so, and it did not work, try running the scf /scannow command per these instructions to see if it can fix that corruption or (at least) identify the corrupted files/drivers: http://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html Once done, you may be able to recover a stable driver/file from your Win 7 installation DVD (as described in the above procedure). Other options: Use a system restore point (if available) Do a repair install: http://www.sevenforums.com/tutorials/3413-repair-install.html Do an OEM recovery (if applicable) Good luck, UCanFixit Link to post Share on other sites
