It might be easier just to buy a PCI USB 2.0 card if you can get them still. The one's I
had success with in the G4 Quicksilver's had "NEC" chipsets. That is important
as the OS had drivers built in for that.
Any PCI USB2 card that offers OHCI will work out of the box; since this was
also the requirement for Windows 7, pretty much any USB2.0 card on the market
will work.
USB1.1 cards were a different story.
I've only just caught up with this thread....I never realized that you
could use off-the-shelf USB2 PCI cards with PPC Macs.
I recently bought a couple of Konig (NEC chipset, 4 external ports, one
internal) USB2 cards off Amazon to use with OpenBSD (one is now in an
old HP minitower with a motherboard ATI USB chipset that is not
recognized), so when I read this thread I went off and swapped the 2nd
Konig card for the unemployed Grappler SCSI in my B&W G3 PowerMac.
It works fine under 10.4 - System Profiler reports an EHCI USB bus.
The HP flatbed scanner works fine, though I'm not seeing any noticeable
speed-up.
A 16GB USB2 memory stick reads/writes at about 40 Mb/s, compared with 5
Mb/s on an internal USB port and the USB1.1 Belkin card I added many
years ago. That's marginally faster than on my 2009 Mac mini running
Mavericks, before the latter's caching kicks in.
Thanks David & Bruce.
