When I connect my Nexus 7 to my Windows XP (SP3) PC via USB, it's obvious the computer recognizes it and it tries to install ADB drivers. Whether I choose to install those drivers or not, I still can't locate my device in the Windows Explorer Tree. I checked Disk Management for the hell of it and nothing but my PC's harddrives were there. There's an attempt to install drivers for "MTP" but that fails and I'm pretty sure that's the cause; however, I'm unable to replicate it, even as I uninstall/reinstall applicable drivers from the device manager the MTP failure never happens anymore. I did some googling and found a thread with someone who had a similiar experience. In turn, I downloaded https://www.box.com/s/2c25e8bc42ecce400afd
to try a different set of drivers. Same problem. Driver install is fine for ADB, but still unable to see my device in Windows Explorer. I'm able to successfully connect the device to the PC with PTP for the camera. I can access DCIM and cache which can serve as a work around, but I'm hoping you can provide any ideas you might have. Thank you!
edit - ***resolution***: Ok, I figured it out...I had to disable USB debugging. I don't know if this helped either, but I installed these drivers as an alternative to the drivers that were originally installed: https://www.box.com/s/2c25e8bc42ecce400afd
While connected to PC, I switched to PTP mode because I was about to give up and just use that
I then disabled usb debugging and switched back to MTP at which point the drivers successfully installed and I could now view my device in Windows Explorer. I also believe downloading the drivers in the link above helped since the first crack I took at this was unsuccessful with existing drivers.
