Virtualbox Usb Device Is Busy With a Previous Request. Please Try Again Later

R. Welling tin't get a USB device to work properly in his reckoner. "What could be wrong?"

Clearly, something is cleaved. Simply is it hardware, software, the device or the computer? That's going to take some experimentation.

First, let's get the obvious out of the fashion: Unplug the device, then plug it once again. Did that fix the problem?

If non, unplug it once again, reboot your PC, and then plug it in again. Did that help? How about trying another port?

No? Well, information technology was worth a endeavour. Since the problem persists, let's get on to more serious tests.

Try the aforementioned device on another PC, and endeavor another USB device on your PC.

If the device fails to work on both PCs, you accept a defective device. You might be able to prepare the problem with a driver update. USB devices are supposed to install their own drivers when y'all plug them into a PC, but occasionally that doesn't work.

Go to the device manufacturer'southward website and see if in that location is a Windows driver available. If you there is, download and install the driver.

If that won't solve the problem, accept that you've got a lacking device. If information technology's new, go hunting for the receipt try to get your money back.

If the device works on another estimator, but not on yours, however other devices practise work on your PC, try installing the driver as described higher up.

If that doesn't work, or if all devices fail on your PC, the problem is with your computer. Merely is it a hardware or software problem?

Endeavor reinstalling the USB port drivers. Hither'south how:

1. Simply to be safe, create a restore point. In the Start menu's Search field, or in Windows 8's Search charm, type restore betoken , and select Create a restore point. Click the Create push and follow the prompts. Don't continue until the restore point has been created.
2. Close all running programs.
3. Open Device Manager. In the Kickoff menu's Search field, or in Windows 8'due south Search charm, type device , and select Device Director.
4. One time in Device Managing director, become to the Universal Serial Charabanc controllers section.
5. Right-click the first listing and select Uninstall. Repeat for all of the others.

   

6. When you lot're done, reboot. Windows will automatically reinstall the drivers.

Warning: If yous're using an external keyboard and mouse, uninstalling one of the USB devices may finer freeze your PC. If this happens, manually reboot the PC and everything will exist okay.

If none of this works, you lot may have a defective USB port. At this indicate, I advise you lot bring your PC to a professional.
