Flash Card reader stops working under 9.1

Folks, This is odd. I've a flash card reader, a dumb little "Dazzle" brand one. It worked with a manual mount under 8.2, but under 9.1, I can't make it mount at all ... neither manually nor automagically. Can I get a pointer to some diagnostic utilities and hints? I'm kinda stumped, the device is acting like it's not plugged in (and yeah, I did check that). -- Josh Berkus Aglio Database Solutions San Francisco
