Kuff's OTG Command

Important Note - this is not a tool for newbies or folks that don't have significant device management experience. If you do not know what OTG is or how it works, please consider learning about it first from Google or via AI resources available through Gemini or Claude. Or find an engineer in your organization that can help you with understand it.

Kuff's OTG Command is a professional USB OTG diagnostics suite built for enterprise field engineers, IT technicians, and deployment teams who need to troubleshoot USB host (OTG) connections on Android — fast.

Plug in a powered dock, hub, barcode scanner, label printer, USB-Ethernet adapter, or flash drive and instantly see the full picture: bus topology, power negotiation, link state, and raw device descriptors. No guesswork and no desktop tools — everything you need to diagnose an OTG deployment in the field, right on the device.

OTG COMMAND DASHBOARD

An at-a-glance health readout of the USB host connection. A live reactor gauge shows OTG status, power role, and connection state, backed by quick-glance stat cards for the metrics that matter most.

USB-PD POWER MONITOR

Watch USB Power Delivery negotiation in real time — power role, voltage, wattage, and live current draw on an oscilloscope-style chart. Instantly spot kiosk power-drain problems, where a docked device pulls more current than the dock can supply.

REACTOR MATRIX — BUS TOPOLOGY

Explore the complete USB bus as an expandable node tree. Walk the hub-and-device hierarchy, inspect VID/PID and USB class codes, and see exactly what is connected downstream of every hub.

OTG ETHERNET DIAGNOSTICS

Validate USB-Ethernet adapters: MAC address, IP, link speed, and a link-state trace, plus a chipset reference to help identify the adapters commonly used in enterprise deployments.

DEVICE DESCRIPTOR INSPECTOR

Dump full USB device descriptors and class references, then copy VID/PID values straight to your clipboard for building MDM / EMM device-filter manifests.

SAMSUNG KNOX & DEX AWARE

Detects Samsung Knox USB restriction state and adapts to Samsung DeX desktop mode for accurate diagnostics on enterprise Samsung hardware.

BUILT FOR THE FIELD

- Designed for barcode scanners, label printers, USB-Ethernet adapters, docks, hubs, and kiosk hardware

- Copy VID/PID for MDM / EMM device-filter configuration

- Responsive layouts for phone, tablet, landscape, and Samsung DeX

Kuff's OTG Command turns your Android device into a portable USB OTG diagnostics bench — power, topology, Ethernet, and device descriptors in a single tool.

Note: USB host inspection requires a device that supports USB OTG / host mode. Some host-level and descriptor features depend on device and OEM capabilities.
