[Aboalfadl]

hello everybody ;
i stuck in this problem for a long time really , i tried everything and i saw most of the topics talking about the same problem and till now i couldn't fix it !!
is there any help ?
for my case i'm using all the operating systems ,
the same version of the VB = the same version of the extension pack,
i did the filters.
no usb can be detected by the machines ! why i don't know

What am I supposed to see in there? Your USB devices on the host? Thank you, but it doesn't help me or you. Now, please explain to me the exact error and what you did. Without pictures. You didn't even tell me what the error is!!!

And please re-read again the linked articles. All of them.

i read all the troubleshot article and i did all the things required from it , it was working before by the way !!
but i don't know why virtualbox turned to hang all usb connected to it.
in the pictures it seems to anyone that the usb is captured but it's not running on the VirtualBox.
and if i tried to change the serial port it add the same usb name again with every serial port it add again the same name of the USB and also doesn't running.
so what is the solution.
i tried to reinstall usb drivers for my computer and i doesn't work.
i tried to reinstall another version of Virtualbox with it's extension pack and also the same problem.
so what we can do here.
and thanks a lot for responding and taking care of this problem.

In #2: Capturing a USB device in VirtualBox, there are two ways to capture a device. Which one are you trying? If you're going from the menu, you're trying the "On-the-fly". Is that what you want to do?

I don't need you to tell me "it doesn't work, it doesn't work, it doesn't work". I understand. I need you to tell me the EXACT STEPS that you took. Step by step.

i tried the both ways. by the way am using VirtualBox from more than 5 years. i'm not new using the VirtualBox and this error the first time to see it.
-------
the first case is "on the fly"
devices -- USB -- kingstone data traveller 2.0
targeted machine was windows 7
the USB captured but doesn't loaded.
if i clicked again to it's name it gives me this error :
-------------------------------------------------------------------------------------------
Failed to attach the USB device Kingston DataTraveler 2.0 [0100] to the virtual machine Windows7.

USB device 'Kingston DataTraveler 2.0' with UUID {b06bf3ad-6d81-49a3-92f7-e02fc694278f} is busy with a previous request. Please try again later.

Result Code: E_INVALIDARG (0x80070057)
Component: HostUSBDeviceWrap
Interface: IHostUSBDevice {c19073dd-cc7b-431b-98b2-951fda8eab89}
Callee: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}
-------------------------------------------------------------------------------------------
this error because the machine already captured it but it doesn't mounted to the machine , i test this case with windows 7 and linux and the same error.
as these stips also if i did the filter the same happens

1. Did you eject the Kingston from the host?
2. Is the Kingston a USB3 device? If yes, did you install the drivers in Windows7?
3. With the USB device plugged in and the VM not running, post the output of the following commands:

   • VBoxManage -version
     VBoxManage list extpacks
     VBoxManage list usbhost
     VBoxManage list usbfilters
     VBoxManage showvminfo "Your_Virtual_Machine_Name"
