Issues Fixed in the NI-488.2 3.1 Update
NI-488.2 for Windows, Version 3.1, adds support for direct entry into ni4882.dll. Previously there was only support for gpib-32.dll.
In certain PXI Express chassis, the performance of GPIB writes through PXI-GPIB interfaces is very slow. This has been fixed.
When disconnecting a USB hub with GPIB hardware connected, the GPIB hardware will not be properly removed from the system. This will prevent the use of the device until the system is rebooted. During the following reboot or shutdown, a blue screen error may occur. This has been fixed.
When disconnecting a USB hub shortly after connecting a GPIB-USB-HS to the hub, a blue screen error may occur immediately. This has been fixed.
Removing PCMCIA-GPIB interfaces while Windows is hibernated or suspended causes blue screen error during resume. This has been fixed.
GPIB interface remains in locked state after the locking process is terminated unexpectedly. This generates an ELCK error on subsequent attempts to open the interface. This problem impacted all USB based GPIB interfaces. This has been fixed.
