Hello greg, > It should be changed to point to where the usbfs files are now located > (i.e. /dev/bus/usb/ instead of the old usbfs mount point.) Thanks, your suggestion helped. I changed /proc/bus/usb/BBB/DDD to /dev/bus/usb/BBB/DDD, and, /proc/bus/usb/devices to /sys/kernel/debug/usb/devices in testusb.c. I still have the below isuse when I run testusb. smart_sudo ./testusb -D 006 ./testusb: 006 may see only control tests can't open dev file r/w: No such file or directory - (0:i:/dev/bus/usb) - - - - - - - - - - - ls -altr 006 total 0 drwxr-xr-x 2 root root 60 Sep 8 13:09 . drwxr-xr-x 9 root root 180 Sep 8 13:09 .. crw-rw-r-- 1 root usb 189, 640 Sep 8 13:09 001 - (0:i:/dev/bus/usb) - - - - - - - - - - - ls -altr total 0 drwxr-xr-x 3 root root 60 Sep 8 13:08 .. drwxr-xr-x 2 root root 60 Sep 8 13:08 003 drwxr-xr-x 2 root root 60 Sep 8 13:08 004 drwxr-xr-x 2 root root 60 Sep 8 13:08 005 drwxr-xr-x 2 root root 100 Sep 8 13:08 002 drwxr-xr-x 2 root root 160 Sep 8 13:08 001 drwxr-xr-x 2 root root 60 Sep 8 13:09 006 drwxr-xr-x 2 root root 60 Sep 8 13:09 007 drwxr-xr-x 9 root root 180 Sep 8 13:09 . - (0:i:/dev/bus/usb) - - - - - - - - - - - Just wanted to check if you have any thoughts, please?
