My 2.4GHz wireless mouse works strangely in Mac OS 9..
« on: April 30, 2025, 09:46:43 PM »

I've purchased UGREEN 2.4GHz wireless mouse few days ago. When I connected the USB receiver to the NEC USB card, it was only recognized as a "usbcompositedevice.", I then connected the receiver directly to the USB port on the Power Mac’s logic board. In that case, the System Profiler correctly identified it as a keyboard, mouse, and HID device. However, despite being recognized properly, the mouse does not work at all. Just in case, I installed USB Overdrive to check. While I still cannot move the cursor or perform clicks, the USB Overdrive app does recognize right-clicks whenever I try them. Unfortunately, it still does not function properly...

What's strange is that after Mac OS 9 had fully booted, I inserted the OS installation CD and tried reinstalling just the operating system. Then, after rebooting, a bizarre glitch occurred, almost all the items in the Apple menu disappeared, the control strip was missing, and most applications stopped working. And yet, oddly enough, the mouse started working just fine... Furthermore, the mouse works perfectly well, really well, when I'm at the startup disk selection screen (accessed by holding down the Option key), during the first few seconds of Mac OS 9 booting up, and also throughout Mac OS X.

I’m wondering if there’s some kind of conflict between one of the extension files and the 2.4GHz mouse I’m using. If I could figure out the cause, I think I could simply remove the problematic extension file. Is there any way to identify which extension might be responsible for this?

Thanks.

It is just normal 2.4GHz wireless mouse dongle, not bluetooth… And it is UGREEN product.
And I’ve tested some methods, and I’ve disabled one of extensions called “HID Library” and rebooted, finally it works on Mac OS 9, but… other USB devices such as audio HID devices stopped working. The reason is “HID Library” but I don’t know how to solve it…

But other wireless mouse that I have works fine so I think ugreen wireless mouse seems to have poor compatibility with Mac OS 9.

I've tried this method few minutes ago, but it is all the same... I also have Logitech pebble mouse and it works perfectly without any modifications. But I didn't like it cause size is small, so I've ordered another wireless mouse...
