Summit Semiconductor Confidential
1 Introduction
The LG Innotek USB Tx implements a complete Summit Wireless audio network transmitter in a small,
inexpensive form factor. This guide discusses the required equipment, software and application specific
configurations to operate the USB Tx using: Windows OS, Mac OSX, iOS and Android devices. By using this guide,
you should be able to properly connect the module to your chosen demonstration platform, enumerate the USB
Tx to the host system, create a Summit audio network and play content wirelessly to any attached speakers.
2 Equipment
To operate a Summit network utilizing the LG Innotek USB Tx you will need the following:
• LG Innotek USB Tx
• 1 or more Summit Rx enabled speakers, up to 32 speakers maximum
• Windows PC (Win 7) or Apple Mac (OSX10.10) or iOS device or Android device (Lollipop)
• Powered USB Hub with USB Type A male to USB Type B male (optional depending on USB hub)
• USB OTG Cable (Android)
• Apple Lightning to Camera USB Cable (Lightning equipped iOS device) or Apple Camera Kit (30pin iOS
device)
3 Windows 7
When using the USB Tx under the Windows 7 OS, a device driver must be installed. Summit has provided a
sample driver from Thesycon. This driver will operate normally for 1 hour, after which it will issue a tone every 5
minutes in the audio stream.

3.1 Installing TUSB Windows Driver
It is recommended that you install the device driver prior to plugging in the USB Tx. If you plug in the USB Tx
prior to installing the device driver, you will see the following if you open up your computers Device Manager.
The LG Innotek USB Tx requires a device driver to operate under Windows OS. As part of the release package for
the USB Tx, Summit includes a demonstration USB driver created by Thesycon. The driver is part of the
executable TUSBAudio_v2.29.0_eval_Summit_2015_04_15.exe. This file is an executable archive, which you will
need to expand to your system. Once you do this, navigate to the following location:
<installed_location>\TUSBAudio_v2.29.0_eval_Summit_2015_04_15\EvaluationKit\DriverPackages.
