Ummm ... and where's the rest of the information?

What are you trying to compile?
How do you invoke gcc, what are your parameters for -I?

I don't use *buntu, so can't say what's part of libusb-dev,
but I'd assume the header is; if you do a

Code:

sudo updatedb && locate libusb.h

- what do you get?

Cheers,

dpkg -L libusb-dev
/usr/bin/libusb-config
/usr/include/usb.h
/usr/lib/libusb.so
/usr/lib/pkgconfig/libusb.pc
-------------------

#include <libusb/libusb.h> : Is wrong.

#include <libusb.h> : Will usually work.
EDIT → → #include <usb.h> : Sorry, typo in the above.

I actually don't see a libusb.h in that output :}

Maybe there's no libusb.h at all (there isn't on my
Slackware machine(s)), and including usb.h will do
the trick?

Sorry , my mistake.

#include <usb.h>

Thank you. Didn't know this one.
