Inter-device allows you to change the functionality of other Razer Synapse enabled devices. Some of these functionalities are device-specific such as using your Razer gaming keyboard to change the Sensitivity Stage of your Razer gaming mouse. When you select Inter-device from the Key Assignment Menu, a sub-menu will appear. Any incompatibility between Synapse, Windows, the device drivers, and the device result in issues. Mostly, this comes down to making sure that everything is kept up-to-date, but there can be other problems that are harder to pin down, like dirty or bad USB ports.
The SNAPconnect E12 has drivers to support many USB devices, such as a second SNAP-powered bridge(using an SN220 or SN132 carrier board), Wi-Fi devices, cell modems, or external storage.While the complete details of configuration options available on these devices fall outside the scope of this document,there are some common considerations that may prove useful.

USB Power¶
The USB 2.0 connection on the E12 is not rated as a 'battery-charging' connection,and may not provide sufficient current for high-drain devices, such as some external hard drives.If you find you are having problems with your USB devices(e.g., external hard drives failing to mount, or cellular connections losing their connections),we recommend you try connecting the device to the E12 through a powered USB hub.
Connecting to an Additional SNAP Device¶
The E12 can support a second SNAP-powered node through its USB port.You can connect an SN132 or SN220 SNAPstick, or you can use an FTDI USB-serial cable to connect to an SN171ProtoBoard or some other hardware that uses a DB9 connector to make an RS232 serial connection.This can allow your E12 to act as a bridge between two radio subnets, where radios are on somecombination of different frequencies, different network IDs, and/or different channels.
Razer Synapse Driver Update
Whichever device you use, plug the device into the E12's host USB port and (among other messages) you shouldsee something similar to:
or:
Examples Of Usb Devices
The key here is the line that says converternowattachedtottyUSB#
.You will use this device handle,``ttyUSB#``, to communicate with the SNAP device.In your SNAPconnect application, you would open a connection to the device like this:

Using usb_modeswitch¶
Many USB Wi-Fi and cell modems now come with a small amount of onboard storage,typically used to automatically install drivers when connected to a Windows host.When the device first connects, it appears as a small flash drive or virtual CD-ROM.After installing the necessary drivers, the Windows host sends a signal to the device instructing it to'mode switch' – to unmount the storage and expose itself as a Wi-Fi (or cellular) device.
Ubuntu Linux also automatically handles many of these devices, but there may be some out therethat Ubuntu does not recognize by default.If you find that the E12 is not recognizing your device, consider installing usb_modeswitch
,which contains a library of parameters for converting devices like these.
Then, plug your device in again and you are likely to find that it works as expected.
