USBScope: USB Device Info

USBScope shows the details a USB peripheral reports when you connect it to your phone or tablet through an OTG adapter. It is handy for checking an unknown gadget, a cable dongle or your own hardware project.

• See every connected USB device with its vendor ID, product ID and interface count
• Allow access to one device to read its USB version, class, subclass and protocol
• Browse configurations, interfaces and endpoints with direction, type, packet size and interval
• Check each configuration's declared maximum power and whether it is self- or bus-powered
• View the raw descriptor bytes as a hex dump
• Export the latest report as a plain-text file, or remove it at any time

Requires a phone with USB host support and a connected peripheral. Power figures are the declared maximum, not a live measurement.
