The thumb/flash drive is showing in the dmesg as ad1 but it is not
available to use. It appears the IRQ is blocked by something else.
Either a IOMEGA /zip drive or the fd0. I tried 3 different computers to
test and only one works if nothing else (/dev like fd0 or /zip drive is
hooked up on the mobo.
One of the techs I work with thinks a lot of mobo's have the same
problem when you have more than one outside /dev is attached.
/Zip and /fd0 work but not /Zip if /flash is attached or plugged in.
For example on the last computer I have tried one of 5 on an atm circuit:
The dmesg shows only fd0 normal. The USB0 USB1 and USB2 shows 1> USB3
all connected to a hub on the mobo but only a double USB is physically
useable and hooked to the board. (no way to read any ad* or da* USB).
ad0 is the hd on the box.
orm0 shows the IOMEGA as isa0 connected with vpI0 (parallel) da0s4.
The other 2 computers I tested on are for hardware bench tests and not
on any network.
Thanks for your help.
