Ugh, that old usbdevfs name should go away, it's debugfs that is being used now, thanks for pointing it out. > That problem gets solved when using root user, is it because of the > reason that i have to mount usbdevfs for my current user? > The earlier usbview v1.1 tool required that that is why i am asking you. No, debugfs needs to be mounted at /sys/kernel/debug/ Is it not mounted that way for you? Perhaps it is mounted with root-only access (default for 3.7-rc1 and newer kernels)? I should just port the thing to use libusb instead of debugfs, but that's a larger job for such a low-priority tool. thanks, greg k-h -- 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
