I have H8QGi-F and a Supermicro infiniband card AOC-UIBQ-M1 with firmware rev 2.7.0. After installing the MLNX WinOF VPI v3.2.0 driver I can't use the card. The Windows device manger tells me "This device cannot start. (Code 10)". I tried both Windows 7 and Windows Server 2008 R2. But the card works fine under Linux.
Please ask Supermicro tech support for firmware rev 2.9.1 and upgrade your card’s firmware under Linux.
