This WORD is bit oriented; it can register multiple errors
simultaneously.
WORD m wUsbStatus is becoming obsolete and is retained only for
compatability purposes. It retains the value 0.
Description:
Returns the error status from the USB-CANmodul. If an error
occurred on the USB-CANmodul, the red status LED starts blinking
and a status information is returned to the PC. If a callback function
has been handed over to the function UcanInitHardware (), this
callback function is called, as well as the event
USBCAN_EVENT_STATUS. After calling the function
UcanGetStatus (), the error state on the USB-CANmodul is erased
and the red status LED stops blinking.
