My 2.4GHz wireless mouse works strangely in Mac OS 9..

I posted yesterday, but it turns out I made a mistake. When I connected the USB receiver to the NEC USB card, it was only recognized as a "usbcompositedevice." As you can see in the first picture (my apologies for the Korean text), 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, as you can see in the second image, 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.

process of elimination, disable extensions until the problem stops, then re-enable them until the problem comes back, then you should know what extension(s) are causing this

I've found this. I disabled "HID Library" and rebooted, the mouse finally works but other HID devices such as audio HID devices stopped working... T.T I also have Logitech pebble mouse and it works fine without any modifications, so I think UGREEN mouse has poor compatibility with Mac OS 9..

I think this is a reasonable conclusion to reach here (or OS 9's USB stack isn't very forgiving, which is another way of saying the same thing). USB HID in general is a bit of a mess, full of edge cases, unfortunately.

I agree. After that, I've ordered really cheap 2.4GHz wireless mouse, it works fine... T.T Finally I'm in heaven with generic wireless mouse with USB Overdrive.

Is the Pebble mouse wireless as well? I suspect OS 9 just has bad compatibility with wireless mice in general for some reason, as my generic Walmart 5 button doesn't work either. When I plug it directly in, any movement of the mouse just shoves the pointer against one side of the screen with no way to move it back, and when I use my ADB wombat it just doesn't work at all.

Yes. Pebble mouse works really really well... T.T Even though pebble is modern mouse, Logitech mouse app (I can't remember the name of this app) for Mac OS 9 detects pebble mouse cause it is Logitech's product...
