I plug my 520 (running WP 8.1) into my Windows 7 32bit laptop via USB and sometimes it's seen, sometimes it's not. I don't know why it's so dodgy. Hit F5, poke here, poke there, close Explorer, reopen, there seems to be no sure fire way for the phone and it's SD card to show up. When the phone and SD card are seen, sometimes getting access to files them is extremely slow or seemingly not possible. Right now, for example, I want to copy a JPG I took with my 520 the other day to my laptop and I just can't. Yes, as a workaround I could turn off the phone, open it up, remove the battery, remove the microSD card, insert in the laptop, etc. but what a PITA!
I'd appreciate any demystification or tips on this.
