I have a Nexus 5. It is fairly new - I bought it about 2 weeks ago.
I have previously plugged it into my Windows 7 PC and been able to access the files on it.
However, today when I plugged it in, the PC couldn't find it. Some googling and investigation found that the device driver wasn't installed - and then it said that it didn't exist.
I have downloaded the Google USB Driver from the official site. But when I told it to update/install this driver, I was told the driver didn't exist.
The LG Driver installed, but the PC still doesn't "see" the phone to let me use it as a USB.
I don't want a complicated solution. I just want to be able to get my photos off my phone and onto my computer.
