Os 9 Won't Boot With Us428, Extension / Hardware Conflict? Options

[ElTurko]

Here's a head-scrather for the group:

I'm having problems booting when the US428 is turned on. It either hangs once the desktop starts to appear, requiring a reset, or if it makes it through start-up I get a Finder quit. After the Finder quit, things appear to work OK and I've been able to record although I'm leery of trusting things after a quit. On rare occasions things boot correctly.

Unplug the US428, or leave it plugged in but turned off & everything's fine. Sounds like an extension conflict so disabled all that seemed to make sense and it still does it. Printers and anything else on the USB are turned off. Problem persists.

Try turning the US428 after start-up and the OS never seems to find it.

I reloaded the Tascam drivers. No change.

I trashed some preferences. No change.

Zapped the PRAM. No Change.

I'm stumped. Any ideas?

System:

B&W G3 350mhz / OS 9.2 - has OS X on it, but booting into 9 - not Classic / 640M RAM / 7200 rpm 40G internal HD / 7200 rpm 40G external (Firewire) / US428 / Cubase 4.1

OS 9 is on a separate partition (but the same disk) as OS X. Audio goes to the FW HD.

Thanks in advance!

Well actually those are good questions. I've only had the unit a month or so. It seemed like it worked initially but got flaky later, but I hadn't used it a lot when things went silly.

I'm using the latest OS 9 drivers DL from Tascam. I don't have OS X multitrack software so didn't DL the X driver. The only program I added after getting the 428 up and running was Cubasis so I could see what full functionality looked like. Maybe I need to remove it?

Thanks for your quick reply,
