Hello idiot_savant

"!" on a yellow circle indicates that a device is missing, that Windows does not recognize a device, or that there's a device driver problem. Sometimes the device can work still with this error. This is most common and usually the easiest to fix.

First, double check the connection. Second, try reinstalling the driver and make sure you follow the correct steps if you haven't...refer to the owners manual, if you have already tried that. Reinstall the driver with the Update Driver button ( in the Device Manager select Properties. In the properties dialog box, select the Driver tab. On the driver tab, click the Update Driver button.

Hope this helps

Actually just try first to update those devices that you mentioned above. Update the driver through device manager like I mentioned above.
