My MOBO is ASUS P4P800 Deluxe. I just recently flashed my BIOS to the latest BETA version from the German ASUS FTP site in order to correct my compatibility issues detecting my 300GB Maxtor SATA drive. All was perfect until I tried to connect my mobile phone via USB and something went wrong and it wouldn't detect properly. The phone does, however, show up under USB devices as MOTOROLA USB MODEM, like it did in the past. So I don't know what's the problem... and don't know how related this issue is, but then I saw that under 'System Devices' there is 'Plug-N-Play BIOS Extension' listed twice. First one is fine, second one shows an exclamation mark and under properties it says that there is some corruption in the registry or something. I don't like exclamation marks anywhere under Device Manager. I hope someone can tell me how to fix this... Do I look for a driver? And if so, which one and where? Is this 'device' suppose to be listed twice? Maybe I should just try 'removing' it?
