FAT32 Flashdrive autorun not working in USB 1.0

[rbd]

I have a WINXP Home Edition portable PC (has all Service Packs and updates)
and a 2GB flashdrive.

If I insert the 2GB flashdrive into any of the portable PC built-in USB 1
ports the Flashdrive is properly recognized, is mounted as G:, and works.
But the autorun.inf file is not recognized.

If I remove the Flashdrive and insert it into one of the USB 2 ports on a
CardBus card, the Flashdrive is again recognized, mounted on G:, and the
"Flashdrive (G" windows appears asking what I want to do (which includes
the autorun.inf option).

I took a 256MB flash drive and wrote the same autorun.inf and application to
it. When this is plugged into one of the built-in USB 1 ports the
flashdrive is properly recognized, mounted "Flashdrive (G", and the
autorun.inf recognized.

The main difference between the flash drives was that the 256MB was FAT and
the 2GB was FAT32.

I reformatted the 2GB flash drive as FAT and the autorun.inf now works when
the flashdrive is inserted into one of the USB 1 ports.

Can anyone explain why a 2GB flashdrive formatted as FAT32 will not
recognize the autorun.inf file when inserted into a USB 1 port?

Thanks

PS - the 256MB flashdrive autorun.inf is properly recognized in the USB 1
ports when formatted as FAT or FAT32!!!!

Can anyone explain why a 2GB flashdrive formatted as FAT32 will not
recognize the autorun.inf file when inserted into a USB 1 port?

I'm clueless... so here's a WAG:

Maybe it's related to the size of the drive and the inability of your
system to recognize a 2GB flash drive using USB 2?

The 2GB flashdrive works with no problems in USB 1.0 - FAT or FAT32. Can
read/write entire drive.

Here's something to try: Insert the drive, right-click the drive in "My
Computer", click Properties, AutoPlay tab, and change its default action.

Thanks for the reply - should have mentioned that I had already tried that.
