Uwe Hermann 9ad05e6cd2 scpi_usbtmc_libusb.c: Fix two error checks.
Two error checks had a missing "ret = ", which lead to an incorrect
value being passed to libusb_error_name().

Also, lower the level for those messages from sr_err() to sr_dbg()
since they're not fatal.

README

-------------------------------------------------------------------------------
README
-------------------------------------------------------------------------------

The sigrok project aims at creating a portable, cross-platform,
Free/Libre/Open-Source signal analysis software suite that supports various
device types (such as logic analyzers, oscilloscopes, multimeters, and more).

libsigrok is a shared library written in C which provides the basic API
for talking to hardware and reading/writing the acquired data into various
input/output file formats.


Status
------

libsigrok is in a usable state and has had official tarball releases.

While the API can change from release to release, this will always be
properly documented and reflected in the package version number and
in the shared library / libtool / .so-file version numbers.

However, there are _NO_ guarantees at all for stable APIs in git snapshots!
Distro packagers should only use released tarballs (no git snapshots).


Requirements
------------

 - git
 - gcc (>= 4.0)
 - make
 - autoconf >= 2.63
 - automake >= 1.11
 - libtool
 - pkg-config >= 0.22
 - libglib >= 2.32.0
 - libzip >= 0.10
 - libserialport >= 0.1.0 (optional, used by some drivers)
 - libusb-1.0 >= 1.0.16 (optional, used by some drivers)
 - libftdi >= 0.16 (optional, used by some drivers)
 - libudev >= 151 (optional, used by some drivers)
 - libasound / alsa-lib >= 1.0 (optional, only used by the alsa driver)
 - check >= 0.9.4 (optional, only needed to run unit tests)


Building and installing
-----------------------

In order to get the libsigrok source code and build it, run:

 $ git clone git://sigrok.org/libsigrok
 $ cd libsigrok
 $ ./autogen.sh
 $ ./configure
 $ make

For installing libsigrok:

 $ make install

See INSTALL or the following wiki page for more (OS-specific) instructions:

Device-specific issues
----------------------

Please check README.devices for some notes and hints about device- or
driver-specific issues to be aware of.


Firmware
--------

Some devices supported by libsigrok need a firmware to be uploaded before the
device can be used. See README.devices for details.
