Hi Nico,
thanks for your patch.

This patch tracks the changes in the libusb interface. Nothing changed in the behaviour of the driver, so far.
It will be used by a follow-up patch. It's based on "Enable spi clock setting in dediprog driver".
Signed-off-by: Nico Huber nico.huber@secunet.com
Review follows. The Makefile part checked for libusb 0.1, but it set the linker parameter for libusb 1.0. The code assumed that libusb_error_name() is always available, but that function was only introduced in libusb 1.0.9. There was a conflict between the added device parameter for multiple Dedipro SF100 devices on one PC (r1628) and the removal of get_device_by_vid_pid().
I have fixed and forward ported the code, please check that it works and looks sane.
This patch is completely untested, I only checked whether it compiles. If it works for you and looks sane, please tell me so I can commit.

New version. Fixed error messages and incomplete cleanup in the error case.
libusb header file location is still something I have to fix in another iteration.
