====== USB support ======

You can attach a USB memory stick to Internet Gate's USB port.

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 supported.

:!: Even though in theory FAT32 supports disc sizes up to 2TB, and you can connect USB hard discs to Internet Gate, you should avoid using USB memories with higher capacity than 1GB, as larger sizes tend to slow down mounting and usage of the memory with the Internet Gate.

===== Format =====
The USB memory must be formated to file system FAT32. You can do this formating either in your PC or Internet Gate.

In PC:
  - Insert the USB memory into your PC
  - Make sure it uses file system FAT32: right click on the device’s icon in Windows™ Explorer™ and select Properties to see file system used.
  - If file system used is FAT, NTFS or some other then right click again and select Format to reformat the USB memory to FAT32.

In Internet Gate:
  - Insert the USB memory into Internet Gate
  - Open [[:web GUI:USB web server status page]] from [[:web GUI:main menu]]
  - If file system is not FAT32 a Format button is visible on the page. Click to reformat to FAT32.

===== Usage =====
