I'll do this simple and clear in a new clean posting, without all the other conversations.
A reminder, since updating to Virtualbox 6.1.34 I have experienced on my Windows 7 Guest:
1. Audio static in my recordings, playback, speakers.
2. Failure of my Logi trackball, Bluetooth mouse, no matter what attempts I tried to fix it.
I thought of an idea!
I purchased a brand new (i.e. latest software pre-installed as mice no longer have downloaded software I discovered!)
Corded, regular mouse with important bi-directional scroll wheel so I can use my Windows 7 programs with many windows and scroll bars.
Logitech B100 outer Box and website say:
ON Windows 10 host, I launched Virtualbox, and entered Windows 7 32bit Guest.no hassle no software setup;
Compatibility
Windows 10 or later, Windows 8 Windows 7
[Test 1] Plugged cord into dongle where all my flash and other items are located, and where the Bluetooth mouse used to be plugged in with its small USB.
[Result? Failure of mouse to operate.]
[Test 2] Plugged cord into my last open USB on laptop that is directly into computer, no hub, no dongle no nothing.
[Result? Just flashes the items, but no cursor moves or appears, just as I move the mouse randomly almost flashes anything on the desktop. I can't use the buttons to activate anything. Return on my wired keyboard does not activate anything.]
[Conclusion]
Only way to use the computer is via a touchpad on my laptop (which I was advised NOT to go into "why" its impossible for me to use it, just say I can't use it)
One other factor, each time I remove or shut down the VM, and start it again with the corded mouse in a different USB spot, the computer informs me its "installing software for new device" "new device found"...... after it gives a green checkmark.... ......nothing...... I still can't use mouse to direct programs or even the Windows 7 operating system itself on the VM Guest.
Reminder, I have updated to 6.1.34
I have installed the 6.1.34 Extensions
I also (for first time ever) installed the Guest Additions for 6.1.34
One question still to be answered: How do I get "ANY" mouse to work with Windows 7 Virtualbox Update 6.1.34?
[I still have the audio static, I just need a mouse to help moving items around/selecting choices and doing all the attempts within Windows 7 OS to try to fix the Audio Static problem described more fully in:
Attempted Change Screen Size of Machine failed--now stuck in new size
