virtualbox.org

VB: 6.1.4
Host: Linuxmint 19.3.
Guest: Win7 Pro x64.
Guest additions pack has been installed.

The guest declares "No USB devices attached" and nothing I have tried will cause any to be recognized.

The instructions in the end user docs allow me to confirm the problem bu offer no insight about how to correct it.
For example:
~$ VBoxManage list usbhost
Host USB Devices:
<none>

Yet, here is what the host reports as attached devices:

$ lsusb
Bus 002 Device 004: ID 0a5c:5800 Broadcom Corp. BCM5880 Secure Applications Processor
Bus 002 Device 003: ID 0951:1666 Kingston Technology DataTraveler G4
Bus 002 Device 002: ID 8087:0020 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 007: ID 04a9:221f Canon, Inc. CanoScan LiDE 500F
Bus 001 Device 006: ID 413c:2003 Dell Computer Corp. Keyboard
Bus 001 Device 004: ID 413c:2513 Dell Computer Corp. internal USB Hub of E-Port Replicator
Bus 001 Device 005: ID 045e:07b2 Microsoft Corp.
Bus 001 Device 003: ID 413c:2513 Dell Computer Corp. internal USB Hub of E-Port Replicator
Bus 001 Device 002: ID 8087:0020 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Any guidance what to do next is greatly apprecieated.

Please provide a VM log file. With the VM fully shut down, right click it in the GUI. Select "Show Log" and save "VBox.log" (no other file) to a zip file. Attach the zip here.

USB Basics and Troubleshooting.

As requested, I hope. The raw *.log is 10 kB larger than the system will accept.
Further to my previous, after following the advice in the USB troubleshooting link you provided, one thing I failed to mention is that with the VM running, the inserted USB stick opens in the Host file manager and nothing (obviously) in the guest.

I know, that's why the instructions said to zip the log. Tar.gz is also good.

I don't see any sign in the log that you created a USB filter, so I can't tell what device you're trying to connect? Is it USB3/xHCI? And if so, did you install xHCI drivers in the Win7 guest?

Did you add yourself to the "vboxusers" group on your Linux host?

[bleep]!
I had done everything to add myself to the vboxusers group except the last step - logging out/rebooting. DOH!!!
I don't usually turn off my computer but yesterday I did because of thunderstorms in the area and loss of electrical power - a frequent occurrence where I live. This morning when I turned it on and went in to restart investigating ... well, no need to explain further except USB is working.
I appreciate your patience and help plus pointing me to the post which I hadn't found that explains very clearly the steps to take.

Thanks for reporting back.
