hi, i just installed wireshark in win 10, wich actually installed usbpcap, and noticed that just after instalation the machines in virtualbox could not recognize the usb anymore, i´m always getting the "USB device is busy with a previous request" error, i tried the add filter options in virtual machine, got nothing, i tried to uninstall it and go to HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > Class > {36FC9E60-C465-11CF-8056-444553540000} and delete the UpperFilters reg key, got nothing.
i RE-installed it and uninstalled it back again using Revo uninstaller and Ccleaner and nothing.(also removing the reg keys)
i already made a huge research and found that this BUG is VERY VERY OLD, and still keeps walking in this 2018, (great job dev guys). i really don´t know what else to do, can´t work on virtualbox because it can´t recognize the usb ports.
relly hope somebody can help me on this. thank you very very much in advance.
