Windows 7 Pro Not Seeing USB

[mjgreer]

I have a Windows 7 Pro guest running on a Linux Mint 19.2 host. I've installed Guest Additions on my Windows 7 Pro guest, and my $USER is added to the vboxusers group.

I've tried the USB 1, USB 2 and USB 3 interface.

I keep getting the error message, "Failed to creat a proxy device for the USB device. (Error: VERR_PDM_NO_USB_PORT). NS_ERROR_FAILURE (0x800004005)

I'm running this on a HP Pavilion G6 -2231DX notebook.

USB is a network. You don't "see USB". You see devices that are connected to ports, but you say nothing about the devices or the ports.

And there is no use trying USB1, USB2 and USB3. You only need to try the correct one, i.e. the one matching your device and the host port you plugged it into. Then consider why it doesn't work.

For example, Windows 7 has no native support for USB3 (which came out after Win7), so USB3 devices won't work before you install the Intel xHCI (USB3) drivers in the guest. I.e. if you install a USB3 device into a USB3 port on your host PC then that device will be inaccessible to Win7 unless you installed the xHCI drivers.

Thanks mpack,

OK. It is a USB thumb drive or memory stick I'm inserting into my USB port that I'm not seeing. I'm using an older notebook, not too old, less than 10 years old, so, I believe all of the USB ports are USB2. They are not blue ports, although, I know that doesn't mean much.

I am using an HP Pavilion G6 -2231DX.

I am trying to read a couple of memory sticks, the first one I tried was a Kingston DataTraveler 16GB thumb drive, then I tried an older PNY 8GB thumb drive and got the same results.

Regardless, the error message that I'm getting, doesn't seem related to the device I plug into my notebook.

I see I did specify my hardware, and I did explicitly add that I've tried all three kinds of USB interface in Virtualbox in case it was an interface issue.

Besides the specific kinds of device I am trying to read, I really don't know how I could be more specific.

The host is Linux Mint 19.2 Cinnamon, and the guest is Windows 7 Pro.

Nevermind, mpack,

You're a genius!

I didn't understand about the USB filter before. The link that you sent me too, especially point #4 solved the problem.

Thank you very much.
