Hi, I had kernel-3.4.52, libusb-0.1.12 and usbutils-0.71 on my centos and lsusb command was working properly. After I upgraded kernel-3.14.9 and also upgraded libusb-static-1.0.9, libusb-1.0.9, libusb-devel-1.0.9 and usbutils-006 rpm packages, lsusb command stopped working and I started getting an output like this: libusb: 0.000000 error [op_init] could not find usbfs unable to initialize libusb: -99 I know that there is no CONFIG_USB_DEVICEFS parameter in kernel parameters newer than 3.5 kernels. So what should I do? Should I compile the kernel with new parameters or write codes for libusb-1.0. Can you offer a solution? Note: I have compiled kernel-3.14.9 so I put kernel parameters about usb config below: $ cat .config | grep -i usb | grep -v \# CONFIG_BT_HCIBFUSB=m CONFIG_CAIF_USB=m CONFIG_USB_CATC=m
