Hello Greg, > 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)? Yes you are right i verified "/sys/kernel/debug" has root-only access. The kernel version i am using is 3.0.0-26-generic(Default kernel provided by ubuntu 11.10 amd64). > I should just port the thing to use libusb instead of debugfs, but > that's a larger job for such a low-priority tool. If you don't mind i would like to give it a try, though most of the terminologies i don't know but i would like to give it a try, just guide me on way of doing it thats all. -- Regards, Anil Nair -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
