All USB devices conforming to the USB Mass Storage Device class of the USB 1.1 and USB 2.0 standards can be used provided they use the file system FAT32.
No other USB device classes are supported. No other file systems (like NTFS or FAT) are not supported.
Even though in theory all device sizes are supported, you should avoid using USB memories with higher capacity than 1GB, as larger sizes tend to slow down mounting and usage of the memory.
The USB memory must be formated to file system FAT32. You can do this formating either in your PC or Internet Gate.

In Internet Gate:
