...for exemple, if I'm running Mac OS 9.1 (OS with USB/Firewire support) on
a 6100 (PPC, non-PCI), could I use an Serial/USB adapter to use USB-only
hardware with Mac OS 9 support, like the modern Canon Powershots?

The adapters of that sort plug into a USB port and provide serial ports. They do not plug into serial ports and provide USB. You could get them to physically attach to the machine with a variety of adapters, however they wouldn't work.


In general, you can translate from a smarter interface to a dumber interface fairly easily, but not from a dumber to a smarter. This is why you can go from USB to Ethernet fairly easily (and most other things, USB is fairly smart), as well as SCSI to various things, etc. However, converting from Serial (essentially a dumb bit pusher/puller) to USB (complex interface with hot-swapping, unique device IDs, etc etc) would essentially take building a whole USB controller with a serial interface of its own, plus software on the other end to handle decapsulating the device ids, data, etc etc. Granted it's certainly possible with the "tossing enough money at it" approach, but current devices don't do it.

Would be neat though.
