First, what is the device titled, "Modem Device On High Definition Audio Bus"? It says a driver for it is missing, but every time i try to update the driver I get the message that the driver cannot be found. Therefore, when I uninstall this seemingly useless device it pops right back up after I restart my PC in 'Found New Hardware" telling me the same driver problem.. It's a vicious cycle, here. Therefore, can someone tell me how to fix the driver, or how to uninstall the device permanently?
