USB Flash memory stick emulation:
In the firmware update mode, the QLG2 pretends to be a USB Flash memory stick, having
a 4MByte capacity and implementing a FAT16 file system. This virtual “Flash stick” contains

Click the OK button.
The File Manager window will then open, and on my system looks like this:
