Yes, when I boot from OS 9.2 the Flash is recognised.
Recent bits of software have made me consider going to 10.4 but
my disk drive is for CDs only. Would have to purchase a CD
version and then take all night to install!!
Are you finding OS 10.3.9 stable?

Hi Merv,
Just a thought ,,,You are plugging the drive into the iMac's USB
port?
Don't use the keyboard's ports or ports on a USB hub, use ports on
the iMac itself.
OSX 10.2.8 should be able to read a MS-DOS formatted USB Flash
Drive.
Another thing ... are you ejecting it correctly from both the
iBook & iMac 'File > Eject'.
You could also run the Update Combo 10.2.8

The device came with a USB extension chord which I plugged into
the back of the iMac. I have also tried a direct plug in with no
success.
Ejecting correctly? Not at first, dragged the image to the trash.
Already running on the update
Your interest appreciated.
Merv
Today I checked out another make of USB Flash and and it worked on
my 10.2.8. It is formatted as DOS FAT 16.
If the offending flash was similarly formatted might it make a
difference?
Disk Utility only offers FAT 32, and given file sizes that is
understandable. However, it might be worth a try, but how.
Merv
Hmmmm !
We still have not confirmed what current that Talent Flash is trying
to draw ,
and whether your USB port is able to deliver without a voltage drop !
Remember it is a USB2 trying to make out like a USB1.1 ... which is
not
normally a problem ... but ...
Was the working USB flash a 1.1 or USB2 ?

Hi Bob & Merv,
From what I have read USB devices draw power from the USB bus. They
can either be a "low-power" device or a "high-power" device. The
high-power devices draw the full 500mA that USB allows. Low-power
devices draw no more than 100mA or so. When a device is plugged into
a USB port, it identifies to the host whether it is a low-power or
high-power device. The host computer is then able to determine if it
can supply enough power for the device.
If it can't, the USB port is shut down to preserve the circuitry.
The newer SanDisk Cruzer Mini devices (they are long and thin rather
than short and stubby) draw slightly more power than a low-power USB
device is supposed to.
A Mac sees this discrepancy and shuts down the USB port. Once the
port is shut down, it's down for as long as the machine is running.
Rebooting the Mac helps, but not always.
My guess is that the Apple USB implementation is following specs and
correctly shutting down the USB port when too much current is being
drawn.
I have a 1GB Super Talent Ultra Flash USB2.0 Flash Drive formatted
MS-DOS FAT32 works fine in OSX10.4.7.
I'm thinking like Bob, that perhaps your Talent flash is drawing too
much power from your USB port & therefore shutting he port down.

Ronni
Even so , it's queer that this thing is recognised and will mount when
the Mac is booted in 9.2.2 ???
and the device is recognised and will mount on a different Mac ! ?
Merv, try and find another USB flash that is formatted in Fat32 .
This is the first time I have heard of FAT 16 , but I guess it must
be used somewhere !
Bob
