#28 Better error messages

[Alex Mastro]

It would be good if this tool would take advantage of libusb_error_name() when printing error messages.

i.e.

errx(EX_IOERR, "Cannot claim interface - %s", libusb_error_name(claim_result));

Thanks, that is a good idea. Can you please make a patch, with at least some of the places covered?

[Alex Mastro]

Sounds good - attached.
