What USB devices are connected when instability occurs?
Happens regardless of devices

Which of these devices has its own power supply?
I generally use a high powered USB3 hub (Hoo Too) for drives and powered hubs for everything else
...
Does the problem occur if you only have a USB mouse and keyboard connected (and internal Bluetooth connected to F_USB)?

A complete list of the attached USB devices can be critical in trying to determine whether the problem is related to:
  • A specific device (especially one that consumes too much USB bus power)
  • A combination of certain devices
  • The ports into which USB devices are connected
    • For example, the Blue and Yellow USB ports on the back are tied to one internal USB hub, so they share bandwidth and power of the single hub
    • This means all USB data from these 4 ports gets tunneled through one USB channel. All 4 ports cannot operate at maximum USB throughput because of this
    • The red USB ports are independent and can both operate at full bandwidth
A general note about USB hubs -- all USB devices connected through a hub are bottlenecked because they share one USB lane to the motherboard.

This is why we ask what devices are connected. Depending on the answer, we then ask for a description of how the devices are connected and into which ports.

Not for me. Only issue rolling back to 0.7.1 resolved, was allowing bluetooth functionality to be restored. USB dropping out remains unchanged.
I think the Bluetooth being restored is the USB 2.0 coming back. With 0.7.5 I had no USB 2.0 ports working. I’m on Mojave. 0.7.5 worked with Catalina for me.

  • What USB devices are connected when instability occurs?
    • MOTU Microlite (MIDI Interface), Antelope Audio Orion 32+ Gen 3 (audio interface), Axe FX II XL (audio/MIDI interface), Apple wired keyboard, QuNeo drum pads, P4 MIDI keyboard/controller, Qcon Pro X and XS (issue occurs often when these are both plugged in and on - the X has a 4-port hub on the back, issue is possibly more frequent when both are plugged into the same USB bus-i.e. both yellow, red or blue ports together, or when the XS is plugged in via the hub on the back of the X)
  • ...
If the two Qcon devices (X and XS) are disconnected, does the frequency of the problem decrease from once-a-week to less often?

The list of devices is:
  • MOTU Mircolite
  • Antelope Orion 32+
  • Axe FX II XL
  • Apple Wired Keyboard
  • QuNeo Drum Pads
  • P4 MIDI Keyboard
  • Qcon Pro X
  • Qcon Pro XS
It sounds like most of these are self-powered and relatively low bandwidth. For example, transferring large files is a high bandwidth operation, but most audio traffic should be relatively low bandwidth unless very high bit rates are being used. It also sounds as if all of these devices would not typically be used at the same time...

But if these devices have their own device drivers (kexts), the problem might be related to those drivers.

Edit: Which NVMe SSDs (M.2) are you using?

USBInjectAll 0.7.5 correctly compiled for Mojave. Been using it for months and absolutely no USB issues for me on an Asus Z370 board.

Didn't realize unlocking CFG and unlocking MSR are same, I did that for whatever reason it shows up as 0x00. see attached pic. does that mean its unlocked?
Yes, it's unlocked now. If the return value is 0x0, it's unlocked.
