There are stand alone installers as I linked previously - use them rather than grabbing individual files.

USB Adapter Card Support 1.4.6 - Macintosh Garden
kmos9: USB PCI card under Mac OS 9.2.2 by Joerg Weise London, UK Q: I have installed a USB PCI card in my beige PowerMac G3 (or any other Power Macintosh computer without built-in USB ports) running Mac OS 9.2.2, but the card is not working / not recognized by the system. What can I do?

Thanks for those
With an 8.6 install, is there nothing that I would want to pull from 9.1 or 9.2.x CDs? With my ZuluSCSI, I was thinking of keeping an OS 9.x ISO on it for convenience if there's anything there I'd ever want, since I get 6 SCSI IDs. But if there's nothing on those I'd want, then I wouldn't do that. If there are things on there that I might want, which OS 9 version ISO would be best?

Just install a copy on a second disk or on a partition. 90s macs are really easy to dual and more boot. You can boot from any SCSI disk, and you can partition a disk as many times as makes sense and boot from any partition. Absolutely no difficulties. Partitioning needs the drive wiping (usually), but other than that inconvenience, is a 5 minute job in Drive Setup (made easier with the cracked version that doesn't need an Apple disk).
I feel sometimes people overlook that you only really have to pick which OS version you use, not which you have installed. A few partitions or disks and you can have 7.5.3, 7.6.1, 8.1, 8.6 and 9.1 all installed and bootable on your 9500.

This makes sense since I have a clamshell iBook with 9.2.2 and it is very, very stable. Not that my beige G3 is so bad, or anything, but it's not quite the same.

This made me LOL. (Sorry.)
I do not want to dual boot Mac versions on this computer. If I need to run a different Mac version, I will simply run it on a different Mac.
I am using a single SD card via ZuluSCSI, which can contain 6 virtual drives, presented as individual SCSI drives, each with a unique SCSI ID. I have heard of people pulling software from OS 9.x to be used in 8.6. What I want to do is just have one of those virtual drives be an OS 9.x ISO. If there is software I would want from an OS 9.x ISO, I don't know if I'd want an OS 9.1, 9.2.1, and/or 9.2.2 ISO

How come? It's... normal to do so. Back in the day we multi booted. It's not like windows, the installs are completely independent and you just switch which you boot from with the Startup Disk control panel, it's trivial. I mean, you don't have to, but I don't see a reason against it.
I'm quite intrigued.
I don't see a reason for it. If I'm going to multi boot, I would do significantly different OSes, like Linux, NetBSD, and OS X. Dual booting 2 slightly different versions of MacOS has no appeal to me. If for example I go 8.6 on this Mac, and I really wanna run 9.1, I would just do it on one of my Blue G3s.
interesting, I might try that. What about bugginess and crashing?
I am not sure either. It seems to have a periodic freeze, say every 10 seconds for example. Just using the file manager seems very sluggish. What G3 card do you have? I have a Sonnet, which unfortunately I haven't figured out a way to disable speculative execution on this one, which I think could help. Maybe I could throw my 450MHz in which does allow me to disable speculative execution and see if that helps. Also, all my RAM slots are filled and inter-leaved, which I believe is often not recommended with G3 upgrades. Lastly, there's a lot more going on I think with the ZULU SCSI compared to your SD to ATA adapter, so perhaps there's an issue there.

You don't have to use the Sonnet drivers. Remove them, install PowerLogix CPU Director and use that to turn off Speculative addressing.
I use CPU Director with my Sonnet.

I have a NewerTech 400 MHz model, not sure how they differ. All my RAM slots are filled to >512 MB. You may be onto something with the Zulu SCSI. I tried to get a SCSI2SD v6 to work in there, and I never got it to function reliably. Weird file corruption, slowness, etc…never could pin it down. This is with having 4-5 other SCSI2SDs working fine in other Macs…this one just was not having it. Next I tried ATA to CF, and the CF card would take forever to read/write, especially in 9, so shutting down would take 2 minutes, games would take long to load, etc. perhaps try using a real HD and see if the issues go away (this was how I ruled out my problem).
Oh awesome. CPU Director wouldn't allow me to boot when i had a Sonnet G4 on my carrier card, so I stopped using it. But I have since replaced the G4 with a faster G3, so will give it a try again. I really like CPU Director so that makes me very happy to know it can work with the Sonnet.
Well I got 9.1 running pretty nicely. Can't say for sure what did it. I used CPU Director to enable backside cache (I didn't have backside cache enabled every time I tried 9.1 previously, which may have soured my opinion), set to 2:1, and disable speculative execution. In the memory control panel I set my disk cache to 16MB (probably overkill) and disabled VM. On the ZuluSCSI, I disabled parity checking (probably OT but any known downsides to enabling this?).
I will note that launching SpeedMeter locked up the system, but I think this would have happened on 8.6 as well. Seems to be an incompatibility with the Sonnet CPU I think.
I think I will consider this my stable install for now, but do plan on trying 9.2.2 soon.

9.2.2 should be fine. You'll need to use OS9Helper, of course. I ran 9.2.2 on a 7500/100 that had been upgraded to a 200MHz 604e, then, later in my use, a NewerTech G3/300. Was required by a chat program I used at the time (the old MSN Messenger app). I eventually switched to a 9600, but moved both the hard drive and the G3 processor card over to that computer. Continued to work as it did in the 7500.
*edit* That same 9.2.2 install is currently in use on my G4 Digital Audio.

I swear this setting tops out at ~8MB
May change depending on installed RAM. Let's me go up to 32MB, and I have 320MB RAM

Just tested this on my clamshell iBook - this machine runs OS 9.2.2 and has 544MB installed. You’re right, the disk cache goes up to 32736K (not 32768K). On newer Macs, I’ve always just left it on the automatic setting and never thought to try increasing it above that. I think older Macs do top out at around 7 or 8MB though.
16MB definitely would be overkill for you, I would have thought.
