VISA Device Driver Problem ?

Hello , I'm having an issue with being able to access a 3rd party PCI device via MAX. The device appears in MAX , however there is a yellow circle across it with an exclamation point. I used the NI VISA Device Driver Wizard to create & install the necessary INF file for this device and I can see from the Windows Device Manager that it was recognized and is working properly. My PC is a Dell - Core 2 Quad (2.4Ghz) running MS Windows XP Pro Version 2002, Service Pack 2 and I am using NI VISA 4.4.1. With a PCI bus analyzer I can see the card being accessed (Config Read/Write) during boot-up and everything appears to be normal. With NI-Spy running I get the following when MAX is launched: > 369. viOpen (0x026AD7F8, "PXI9::4::INSTR", 4, 0, 0x00000000) > Process ID: 0x000007A0 Thread ID: 0x000012F8 > Start Time: 09:56:27.224 Call Duration 00:00:00.000 > Status: 0xBFFF0000 (VI_ERROR_SYSTEM_ERROR) Thanks in advance for any suggestions, Regards, Bill
