Hardware Systems Engineering
PROVEN, Inc.
Consulting Engagement: USB & Serial Communications / Windows Platform Stability
About the Engagement: We operate a large fleet of automated kiosks running Windows in unattended, high-uptime environments. Persistent communications failures across USB and serial-connected subsystems are requiring frequent reboots to restore normal operation. We’re seeking an experienced embedded systems / Windows platform consultant to independently investigate root causes and recommend durable solutions.
Scope of Work:
Audit USB and serial (RS-232/RS-485) signal integrity on kiosk hardware — voltage margins, cable/connector quality, EMI/noise susceptibility
Analyze Windows USB host controller behavior, driver stack stability, and COM port enumeration under extended uptime
Review Windows Event Logs, USBView/USBDeview data, and any existing diagnostic captures
Identify root causes of device disconnects, enumeration failures, and conditions requiring reboot
Deliver a written findings report with prioritized recommendations (hardware, driver/firmware, OS configuration)
Ideal Background:
5+ years in embedded systems or hardware engineering with a focus on USB and serial communications
Hands-on experience with protocol analyzers (Total Phase Beagle, Ellisys, or equivalent)
Deep familiarity with Windows driver stack, USB host controllers, and COM port management
Experience with unattended / kiosk / retail automation hardware a strong plus
