i'm using libusb in intel edison board
lsusb command shows the usb device but when i try to run the code I get this error:

root@admin:/root# ./out
Error finding USB device

here is lsusb command output:

root@admin:/root# lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 0483:3748 STMicroelectronics ST-LINK/V2

I tried on my laptop and everything works, even without `sudo`. How are you compiling it? Which library are you linking? – Rogus Apr 19 '17 at 12:18
here is my compile command: gcc -L /usr/local/lib usbcode.c -o usbcode -lusb-1.0 i had no compile errors – ahmad eqbal Apr 19 '17 at 12:27
then try `./usbcode` instead of `./out` – Rogus Apr 19 '17 at 12:47
i compiled with different names, out and usbcode. both of them had same error – ahmad eqbal Apr 20 '17 at 20:08
Maybe you should try the http://communities.intel.com, there are some posts on `libsub` there. It seems a lot of people are struggling with usb in the intel edison board. – Rogus Apr 21 '17 at 07:51
@Rogus, it works for me, though I'm not using official BSP at all. – 0andriy Apr 22 '17 at 08:54
