Hi! There is also sysutils/usbutil which provides usbgen package
With that you could get the USB descriptors with something like: doas usbgen -D -v -f /dev/ugen1 on OpenBSD. However AFAICT it works with generic ugen devices. I don't know how to debug for example a USB mass media device. That being said, I have missed many times non-existing verbosity level for usbdevs which would dump at least device descriptor. Would this be desirable enhancement?
