Does this cause conflicts? Anybody using this setup? I have a ton of peripherals, and would rather have the extra 12Mbps ports than have all of them attached to one.
Thx.

Works like a champ... I'd recommend Entrega's 4-port card for maximum Port-a-ability.

It should just work like additional built-in ports on your G4. The only caveat is that you may or may not need extensions to drive the card.

works fine with my keyspan 2-port'er. no drivers needed, just sock it in and go. to power on from the keyboard, though, it needs to be plugged into the built-in ports.

Another thread in peripherals suggested getting a card with separate busses for each port. Why are separate busses superior--fewer USB conflicts? more power?--and does the Entrega have separate busses?

I seem to have been having USB conflicts (crashes--also caps, num, and scroll locks coming on at random) when my Intellimouse optical and printer were plugged into a hub.

Now the conflicts have stopped after a clean install, with Macsense USB-600 keyboard and Intellimouse Optical plugged directly into the computer--the mouse sometimes freezes when plugged into the Macsense keyboard--and no other devices yet installed.

Might a card with separate busses help?

A USB bus is 11 Mbps. If you have 4 devices on one bus, they must share that bandwidth. If all are accessing it at the same time, devices like printers, scanners, and Zip drives will slow down.

It used to be with Macs (and I think it still is with all PCI cards), that all the USB ports share one bus. On newer Macs, Apple gave each USB port its own bus.

If you have independent busses, you can use more devices since you effectively have more bandwidth.

I bought the XLR8 Dual-Port USB PCI for my B&W because it has more power on each port than built-in - that allows some devices that otherwise would need their own AC power to work - AND each port had its own controller for 11Mbps. It's only a 2-port card. Bought it 8/99 for $44 and now sells for 1/2 that, and there are 4-port cards. But much better than having to have a hub, have another A/C adapter plug. And allows printer to be further away - up to 15'.

I wish Apple would do little things like iMac and G4's w/ 4-port USB, USB 2.0. It was shocking to read what problems early adopters of USB (iMac Rev A-D) had with printers and other devices and a mess of hubs and cables, driver conflicts, vendors selling USB disk drives that are like huge big slow floppies etc. and "unplug when restarting, then plug back in" as a "fix." Junk science.
