I just ran into a problem. My Sero 7 Pro no longer is "seen" by my Win 7 PC. I tried uninstalling from device manager where it shows with an error icon and re-installing but get notified that it can't find drivers on pc or internet. My device is rooted (xboxexpert method) and I seem to remember it was accessible both before and after rooting. Since that time, I've put in a large number of apps including Link2SD and FolderMount. I just had installed USB OTG Helper to try to read my USBs using an OTG cable but it didn't work so it was uninstalled. Any suggestions? Without USB or pc connectivity, it is tough to transfer files like music other than wirelessly from my LAN or by switching micro SDs. The latter is not easy because of offloaded data and apps on the mounted card.

Problem solved with some tip from androidcentral forum. Turns out, I had USB debugging checked on Developer's Options and it needs to be off to see the Zero as a drive.
