USB not working at all (all devices are busy)

Reported by: Karagul Owned by:
Priority: critical Component: USB
Version: VirtualBox 4.2.4 Keywords:
Cc: Guest type: all
Host type: Windows


USB devices in drop-down list are ALL in "busy" state. If I try to attach one (a USB 232 converter in this example) I get the following error:

Failed to attach the USB device Prolific Technology Inc. USB-Serial Controller [0300] to the virtual machine WinXP Devel.

USB device 'Prolific Technology Inc. USB-Serial Controller' with UUID {1e04c48b-fcb2-4509-bfba-8ea06084b6be} is busy with a previous request. Please try again later.

Result Code: E_INVALIDARG (0x80070057)
Component: HostUSBDevice
Interface: IHostUSBDevice {173b4b44-d268-4334-a00d-b6521c9a740a}
Callee: IConsole {db7ab4ca-2a3f-4183-9243-c1208da92392}

Sometimes, instead, the device becomes "captured" but nothing happens (device is NOT attached) and retrying to attach it yields the same error as above.

This does NOT seem to happen on linux host. Log is attached.

I have the same issue with USB in virtualbox 4.2.6, host OS is Windows 8 64, guest OS is Windows XP Pro 32 bit. Trying to attach any USB device does not bring any visible results, and futher efforts to do this cause an error message telling that device is busy, for example: "USB device 'JetFlash Mass Storage Device' with UUID {0bfa92ef-936c-4558-ab6a-5e04b2bf3777} is busy with a previous request. Please try again later." I have got this problem only on Windows 8 host, I have never seen it in other host OS, such as Windows XP, Windows 7, Ubuntu 12.04, Ubuntu 12.10. Waiting with hope for solution of this problem.

Similar problem with Macbook pro running Mac Os 10.8.2 and VB 426 with windows 7 or windows 8 on the top of it. Any USb device is not launched and a driver problem is reported. Really a big problem for me,

I believe this is the USB 3.0 host only bug described here:

USB function has broken again since 4.2.18 (include), all 4.3 releases doesn't work on some Windows 7 64bit machines. See thread:
