USB device is busy with a previous request, Failed to attach

Post by PradeepCh »

The Host Os is Windows 7, the guest OS is Ubuntu mate 14.04.2 LTS.

In the Virtual Machine,
After I plug the USB device and then I go to Devices->USB Devices-> STMicroelectronics ST32 STLINK[0100].

I get the below pop-up window in the virtual box.
"Failed to attach the USB device 'STMicroelectronics STM32 STLINK[0100]' to the Virtual machine 'Ubuntu mate'.
USB device is busy with a previous request.Please try again later"

I know I selected the device the second time, but still it is not getting detected.

Thanks,
Pradeep

If you obfuscate any information requested, I will obfuscate my response. These are virtual UUIDs, not real ones.
