I use testing steps with a usb disk followed "http://www.linux-usb.org/usbtest/";, I cannot get the following result . root@feng-desktop:/home/feng/usb-test# ./testusb -D /proc/bus/usb/001/087 ./testusb: /proc/bus/usb/001/087 may see only control tests /proc/bus/usb/001/087 test 0 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 1 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 2 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 3 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 4 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 5 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 6 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 7 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 8 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 9 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 10 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 11 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 12 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 13 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 14 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 15 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 16 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 17 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 18 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 19 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 20 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 21 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 22 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 23 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 24 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 25 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 26 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 27 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 28 --> 25 (Inappropriate ioctl for device) /proc/bus/usb/001/087 test 29 --> 25 (Inappropriate ioctl for device) Seem that the usbtest module doesnot support my device.
