That's interesting, I had the exact same problem with my Power Mac 6500/300! Freezing within minutes of play of basically all hardware accelerated games, regardless of it was RAVE or OpenGL.

I have been looking for a project like this. I finally got the parts and soldered one up, and the LED displays correctly, and it works great with a mouse. But anytime I try to plug in a keyboard, it either does nothing or freezes up the mac. Hotplugging a mouse on the USB side works fine (don't hotplug the ADB side ever). I thought maybe the D+ and D- were swapped so I swapped them... then I get nothing. Any ideas?Even though I already have a bunch of projects in various stages after seeing this YouTube video by Kevin Noki on a modernized take on the original Apple ADB mouse I felt compelled to build one! I also built his aesthetically pleasing USB to ADB converter (based on QuokkADB by Rabbit Hole Computing) which was the harder part!) #MARCHintosh!
USB2ADB Converter DIY by Kevin Noki
This 3D-printable case is a basic, no-frills enclosure for a DIY USB-to-ADB adapter for USB mice and keyboards using a Raspberry Pi Pico. It’s designed for those who need a working adapter right now with off-the-shelf parts, without waiting for a more refined version. 🔧 What’s Inside?This...makerworld.com

After triple checking the wiring, it works! I got impatient tonight wanting to test so that LED wiring/resistor will have to be reworked but yay!

On the LED this page was helpful in figuring out a good resistor value for the LED:
(I went with 68 Ohms)
I had a similar problem with mine when using with my Performa 575, USB keyboard didn't work when a USB mouse would. Tested with the Bamboo lab MH002 3D Printed Wireless Mouse, a Raspberry Pi USB Mouse, and a a Raspberry Pi USB Keyboard.
Odd thing, when I test with an original LC everything works... Not sure what to make of that but since I mainly intend to use it with the Bamboo lab MH002 3D Printed Wireless Mouse I haven't looked into it further. I did post a comment about its on the Makerworld page for the USB2ADB Converter DIY
I def don't think D+ and D- would be the issue, if they were swapped it wouldn't break differently for a USB mouse vs. a USB keyboard, they use D+ and D- the same way as understand it.
