Stop hidden files saving to USB MSD device

    I have developed hardware device with very small on-board memory (27 KB), USB MSD (Mass Storage Device) interface and FAT12 file system. Atmel AT91 USB MSD sources was used as reference.

    Some files must be loaded by user to this device, taking near all memory space available.

    System works great with Windows systems.

    But MAC OS (at least MAC OS X v10.4.11) automatically stores some hidden files (".Trashes" folder), consuming valuable disk space. And even worse, Finder application stores its hidden ".DS_store" files too, consuming even more device memory.

    The question is: do I have some possibility, by changing some USB interface settings on my device, or, as last hope, by changing MAC OS settings, to disable automated hidden files storage to my USB MSD device?

    Thank you, this application could be useful by some extent.
    But it doesn't solve ".Trashes" problem.
