USB device is busy with a previous request

[Clodoaldo Pinto Neto]

Windows XP host and Fedora 11 guest. After a crash while transferring a huge amount of files between the pen drive and the Fedora guest, the pen drive becomes unavailable. When clicking Devices -> USB Devices -> Device Name this message is shown:

"Failed to attach the USB device xxx to the virtual machine Fedora 11 USB device xxx with UUID yyy is busy with a previous request. Please try again later.

As I posted in the forums, I was having this exact problem. Solved it by disabling USB 2.0 or EHCI support in BIOS and everything works now. May be USB 2.0 support is not perfect in Virtualbox?

disabiling USB 2.0 in the virtualbox or in the mainboard bios native???

You have to disable USB 2.0 in the mainboard's BIOS.

5 years later, this "USB device is busy with a previous request" is still a problem and happens to me constantly. The only way to resolve it involves rebooting (either or both) my guest and host machines. I see threads all over the internet about this problem with no resolution. In my case I am using Windows 7 x86 with VirtualBox 4.3.10.

Is this ever going to be fixed?

Please reopen if still relevant with a recent VirtualBox release.

The error still occurs with VirtualBox 5.1.26

Turned out the issue is bug #11251
