I'm trying to configure the "USB Emulation" BIOS setting with OpenManage 7.1.382 and WMI, and I'm running into this problem.  On GX240s, it runs fine, as I just want to set USB Emulation to "Enabled".  However, on GX260s and GX270s, I want to disable USB booting, and so I want to set USB Emulation to "No BOOT", which you can do in the BIOS setup screen.

However, when I try to set the appropriate value (USBEmulation = 2) via WMI, it won't take it... it keeps resetting to its old value.  Is there some reason why OMCI won't let me set this value?  When I set it via the BIOS and then look to see what the value is via WMI, it's 2, but for some reason I can't set that value via scripting... any thoughts?
