[Libusb-devel] how to retrieve an usb mass storage serial number ?

[Benoit D. <bde...@gm...>]

Hi,

I'm trying to use libusb to get the serial number of an usb mass storage
devise.

This work when the code is executed as root. But I get a permission denied
when I execute it with a normal user.

I use this exemple:
http://mpathirage.com/getting-started-with-libusb-on-ubuntu/
With normal user, I get:
- Unable to fetch serial number string

How should I do this ?

Thanks,
Benoit
