Using kvaser revealed issues with connect.

bus = can.interface.Bus(interface='kvaser', channel=0, bitrate=500000)
when run this report error

can.interfaces.kvaser.canlib.CANLIBOperationError: Function canIoCtl failed - Error in parameter [Error Code -1]

examining the original files of canlib, there is no longer a definition for canIOCTL_SET_LOCAL_TXACK.

so I commented out the following code, and it works fine now.

# enable canMSG_LOCAL_TXACK flag in received messages

# canIoCtlInit(
# self._read_handle,
# canstat.canIOCTL_SET_LOCAL_TXACK,
# ctypes.byref(ctypes.c_byte(local_echo)),
# 1,
