Force usb driver reload

To do this, expand the Universal Serial Bus controllers group at the bottom of the list. When you have found the hub that has your device listed, click the Details tab and select Device Instance Id from the drop down menu. In the Command Prompt window, first change directory to the folder that contains the devcon. If you are using a bit operating system, you need to ensure you are calling the bit version of devcon.

Now, Windows will remove and re-detect the hub and any USB devices attached to it, re-enabling them in the process. If this does not work, you probably selected the wrong hub in step 4. Repeat steps 3 - 6 until the restart is successful. Once you know which root hub your device is connected to, you can implement this solution programatically in LabVIEW using the System Exec VI , which allows you to pass commands to the command prompt.

My Asus K52F freezes intermittently. I have reinstalled all USB drivers but the problem is still there. Now that Macrium is mentioned, it suddenly dawned on me that Macrium must be the problem. Why has my computer started freezing, but not in Safe Mode? Luckily I had additional USB ports on the front of the computer to get them working. Just a heads up for everybody else! This is especially true of scanners and sometimes printers.

Hi, I had what seems to have been a similar problem after updating my Dell Vostro from Win 7 to Win 10 a few months ago. So the set-up tab for the touch pad was missing, whether I opened the mouse set-up utility or searched for the touch pad separately. Half an hour Googling found a reputable looking according to Web of Trust website, that gave a clear and as it turned out accurate cure. I can once again scroll, and use gestures and all the other tricks that are so useful.

This was an instance where Win 10 simply refused to recognise this bit of hardware for what it really was. The best place to get that driver is the Dell website. The device manufacturer or in the case of laptops the laptop manufacturer is the best place to look for drivers. Hi everybody, I have an intermittent problem with the audio speakers on my Laptop.

What works for me when the sound goes is, go into Device Manager and disable the driver, close the program or whatever is using the sound, then re-enable the driver.

Works every time. Just in case somebod has a problem with the audio. A few suggestions: Firstly, an intermittent sound problem is most likely a hardware issue.

It could be any one of the following: lose connection in the 3. For example, this may be software from Realtek, AudioMaxx, etc. Go to the Windows run menu, type in msconfig and check the Startup tab for anything that suggests audio control.

Then find these applications and go through their settings. You can also start experimenting with shutting off some of these applications and see what happens. To do this you may have to get into the Windows Services and disable services. Also run in Safe Mode to see if you still get the intermittent audio loss. Basically, diagnosing this is a matter of patiently experimenting and trial and error.

One more note: When such intermittent problems start, your first impulse should not be to update the drivers. Software drivers do not break and if you change them before you can narrow down the reason for the problem you may irreparably break something. If audio used to work, then it stops working, your first area of investigation should be hardware. I have an Acer laptop and an Acer external monitor.

I uninstalled the monitor driver to fix a brightness issue and then restarted my laptop. After restarting my laptop, the driver was not reinstalled. Can anyone help? Wednesday, August 7, PM. Thursday, August 8, PM.

Thursday, August 8, AM. Monday, August 12, AM. Did you ever find a working answer? Wednesday, October 9, PM. I've disabled automatic driver installation, yet it gets ignored and the generic driver is still installed as soon as I plug it back in or scan for hardware changes.

It was only after that, that the device setup failed and left me with an unknown device, from which I could then manually update the driver properly and get it to communicate with the data logger.

I then set the permissions and ownership back to what it was. I do, but when I manually select the driver, Windows returns "The best driver for your device is already installed". I need to be able to change the driver to a different one regardless if Windows thinks it has the best one already installed. If you haven't already, I'd try deleting the device from Device Manager with the network cable unplugged.

Make sure to check the "Delete the drive software for this device" box. This way, Windows shouldn't be able to install anything. When you scan for hardware changes, hopefully you'll see a device missing drivers that you'll be able to point to the real drivers.
