Inspect USB devices with full descriptor and HID details
About this app
USBDevInfo (USB Descriptor Explorer) is an utility for inspecting USB devices with clear, structured details—built for debugging, validation, and reverse-engineering.
Connect a device and view:
- Vendor/Product IDs (VID/PID) with resolved names (when available)
- USB version, speed, class/subclass/protocol
- Configurations, interfaces, and endpoint breakdowns
- Power hints (max power)
- Input peripherals (keyboard/mouse) via Android InputManager
With per-device permission granted, USBDevInfo can also retrieve advanced data such as:
- String descriptors (manufacturer, product, serial, interface strings)
- Descriptor tree parsed from raw descriptors
- Device state (GET_STATUS / GET_CONFIGURATION / GET_INTERFACE where supported)
- HID report descriptors and a readable summary
Designed to be fast, privacy-friendly, and practical for daily troubleshooting.

Installation Guide
Open Settings on your Android device
Go to Security → Unknown sources (or Install unknown apps)
Enable "Allow from this source" for your browser or file manager
Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be org.kaijinlab.usbdevinfo is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 1.0.2 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall USB Descriptor Explorer first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of USB Descriptor Explorer, and a listing is removed when the evidence for it stops holding up.

Permissions Required
What each permission lets USB Descriptor Explorer do. A highlighted one is worth a second look — not necessarily wrong, just worth asking whether this app needs it.
Previous Versions
The signing certificate fingerprint for this release is on record, so a build that does not match it did not come from this publisher.
