Comment 48 for bug 1437492

@Jeff

I have an external sound card (Topping VX2). And also a CAD u37 usb microphone. When they are plugged into my machine, it hangs forever at the login screen and won't let me type into the password field. If I remove the devices, it immediately resolves the issue and I'm able to log in. However, after logging in I notice the problems with icons and themes I described above. Also, it seems to nuke my audio as no devices show up in Sound Settings.

On reboot I get usb error messages. But if I reboot without the devices plugged in, I boot normally and have proper theming and sound.
