Scanners and other USB devices that do not require isochronous transfer.
Note:The USB remote connection software is available for Windows 10 / 8 / 7 (64-bit and 32-bit). Isochronous USB devices such as webcams require the instant and continuous transmission of data ("real-time") and cannot be used with the FRITZ!Box.
2 Total number of USB devices
If you are using a USB hub, you can connect up to four USB devices (excluding the USB hub) to the FRITZ!Box at the same time. However, you may only connect one USB printer and one mobile broadband dongle. If you use the FRITZ!Box remote connection software, you can connect up to three USB devices (excluding the USB hub) to the FRITZ!Box at the same time.
The FRITZ!Box treats multifunction devices as several separate USB devices. For example, a printer with an integrated memory card reader is detected as a USB printer and a USB storage device.
For instance, you can use the following USB devices with the FRITZ!Box:
- four USB storage devices
- three USB storage devices and one USB printer
