8.8 Tips for Using USB Devices
USB Devices When using USB devices at the USB port of the FRITZ!Box,
please keep in mind the following;
 If more than one USB device without its own power
supply is connected to the FRITZ!Box, note that, in ac-
cordance with the USB specification, the total current
consumption may not exceed a value of 500 mA. Oth-
erwise unspecified malfunctions with the USB devices
or even damage to the FRITZ!Box may occur.
 AVM expressly advises against installing firmware up-
dates for USB devices connected to the computer via
the USB remote connection on the FRITZ!Box.
USB Mass Storage
Devices
When using a USB storage device at the USB port of the
FRITZ!Box, please keep in mind the following:
 Before removing the USB storage device, select the
“Remove Safely” button in the FRITZ!Box user inter-
face to prevent losses of data.
 To avoid damage to the FRITZ!Box or the USB storage
device, operate USB storage devices that require more
than one USB port for operation (for instance hard
drives with a Y cable) only if they have their own power
supply or a USB hub with its own power supply.
 AVM has no influence over external interference to the
USB storage devices on the FRITZ!Box. Thus such phe-
nomena as voltage spikes during storms may occur,
and writing to older USB memory devices may corrupt
the data structure due to a high number of defective
structures. In such cases a complete loss of data may
occur.
Therefore AVM recommends always making a security
copy of the USB memory content so that your data are
not irretrievably lost.
