Not sure what is going on but I can't get my PC to fully recognize the phone. I can plug it in and see pictures/etc. on it but it still has errors in the device manager. I did some searching and have tried the following.

Remove all entries, power phone off, let it power back on.
Remove all entries, reboot both phone and PC
Download Windows Phone drivers from Microsoft. No go still didn't find and when I manually browse the driver .cab a variety of windows phone and Windows Phone 7 drivers show up but nothing WP8 specific

Any other suggestions on this? I don't know what else to do. I did not have this problem on my work PC which is also Win7 Pro 64bit so it's really confusing me.

Looks like I managed to get it fixed. Found a tip to try running windows update while the phone is plugged in. Sure enough it found an update for the Win USB driver package and the two exclamation mark devices instantly disappeared.

I have this same issue with a 1520 and it does resolve the device manager recognition but still doesn't allow connectivity with Nokia suite.
