Hi, I discovered that the optional strings and their indices of interface descriptors are not exported in debugfs when I was looking at usbview's source (https://github.com/gregkh/usbview/issues/5).
I am not sure yet if they are cached (e.g. in rawdescriptors in struct usb_device or even more conveniently) or if one would have to fetch them with usb_get_descriptor(). More importantly though I wonder if you think it is useful to export them at all? I haven't apprehended the debugfs/sysfs differences regarding USB yet apparently. Maybe a better question would have been "Why does usbview not use sysfs (or even libusb)?". -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
