I. INTRODUCTION

This case study demonstrates how a device lab resolved its USB issues using Acroname’s industrial USB hubs, making the lab more robust and ready to accommodate future expansion.

Hardware device labs need reliable equipment. Often, these labs develop in an ad hoc manner, adding equipment as needed. The reliability and power capabilities of the USB hub itself are often overlooked.

Introduction

Mobile devices are built to maximize how long they can run between charges by topping off the battery when connected to power.  However, in mobile device and Continuous Integration (CI) labs, where hundreds of devices need continuous USB data connections, this presents a challenge. When these devices are USB-tethered for extended periods, the battery is held at a high state of charge (SoC). Long-term high SoC can cause battery swelling and ultimately lead to device failure.
