Trouble connecting to LG phone with adb (Mac OS X 10.7.5)

Question

When I run adb devices there are no devices showing as connected. My device is a LG Optimus Exceed 2 running 4.4.2 There are many of these posts around, so here's what I've done:

• I'm using the cord that came with the phone. It charges and tries to sync photos, so it isn't an issue here. Switching usb ports and trying a powered usb hub doesn't affect it either.
• I've added the vendor id (0x1004) to ~/.android/adb_usb.ini
• Restarted and unplugged any combination of things you can think of
• USB Debugging is on. And has been restarted. Same with Unknown sources.
• I have never used EasyTether, nor is it installed anywhere on my computer.
• Updated adb, updated my sdk.
• Restarted adb server
• Tried installing LG's drivers: http://www.lg.com/us/support-mobile/lg-VS450PP (They say they don't support Mac S/W upgrade, yet they have a package to install. No help there)
• I have a Nexus S running 4.1 that works, and an old LG phone running Gingerbread that connect.

Any wizards out there who've already struggled with this who have advice?

Answer 1

I tried all of the connection types (charge, MTP, PTP) but perhaps not "Internet Connnection, modem"? You can change it by pulling down the system-wide drop down menu and touching "USB connection".

This is how I fixed it, but I thought I'd tried this already, so I can't guarantee it wasn't this in conjunction with one of the things done above.

Answer 2

PTP seemed to do the trick. Never had to do that on any other device...
