To avoid repeating the same code just call __vciFormatError here and add the arguments to the returned string.

Unless you want to add some logging in the event of a VCIError you don't need to catch and re-raise this.
…. Added parameters documentation

* Added minimal configuration file example and parameters description * Added support for time.perf_counter in python3. * Better error messages when hardware cannot be initialized * Leave the IXXATBus name when importing * Use time.perf_counter only on python releases >= 3.3 * Handle VCI_E_RXQUEUE_EMPTY with explicit VCIRxQueueEmptyError exception. Added two (private) functions to decode error codes * Module does not depend on ctypes to decode error codes anymore (decoding done in canlib). * Added VCIRxQueueEmptyError exception * Improved docstrings * Ignore utf8 decoding error when formatting vci messages Not specific to IXXAT: * Update can.rc from Bus.__new__ kwargs

Exceptions are now simple CanError subclasses and do not depend on ctypes to decode error codes. Decoding is now done in canlib.
Not related to IXXAT but
interface.Bus.__new__was not updating can.rc from its kwargs interface and bitrate.Apply to the develop branch.
