USB mouse forcing Safe Boot?
Posted by: DanaTheElf on 2025-10-09 22:23:05
Wondering if anyone has had a similar issue to this.
I got a five button wired USB mouse for my dual 867MHz G4 MDD; I wanted something that looked like the Pro Mouse to match the G4, but with all the functionality of 3+ buttons and scroll wheel. I settled on the "Aula S80" since I got it for a decent price.

Having the mouse plugged in at power-on forces the machine into Safe Mode; rebooting from the login screen, everything works perfectly fine from then on.
At first I thought maybe it was drawing too much current for the MDD's built-in USB ports, but I wanted to expand the USB with a PCI card anyway, so I did that; the issue persisted.

When I bought the mouse, I had intended to remove the RGB Gamer LED nonsense and give some internal pieces a black coat, and convinced it was still a current draw issue I hoped doing so would help. Alas, while the current draw does appear to have dropped after the surgery, the strange Safe Boot problem persists.

Has anyone encountered something like this before? Where a standard USB peripheral simply being connected sends the machine into Safe Boot on power-on, but a soft reboot later, it's all fine?

It isn't actually a composite device and pretending to be a keyboard too or something is it? Check in System Profiler.

I don't think it is.
