EXT3 (LINUX)
This should work fine.
Other Issues
- Some USB keys/drives may not work, well, just because. Not everyone implements the USB spec the same way.
- Some USB drives/cameras may require external power to work properly, even if the documentation says these devices will work with only the power provided by the USB port.
- USB keys can be formatted either as a hard drive (with a partition table and partitions) or as floppy drives. How the USB key is formatted may affect whether or not it works with the Sunrays.
