I have NI 488.2 (driver 19.5) USB-GPIB control card connecting a Keysight 6654A power supply to a PC (win7 64bit).

Under the Keysight IO expert, the power supply is displayed as "Unknown GPIB0::5::INSTR", and cannot communicate to the PC with softweare of any kind. The NI VISA is set to the primary. I have other instruments on the same bench, like N9010, E8257D, E4419B, they are all working correctly. 

Could anyone give any advices?
