[Q] adb devices under mac osx => offline
The adb devices command returns "offline" for my nexus 7, under mac osx 10.7.5. Things I have tried (after having enabled the USB debug option, of course):
- kill & start the adb server
- plug/unplug/power off and on
- turn off and back on USB debugging
- change the USB port
- permutations of the options above
I have never been prompted (as I would have expected) to "trust" my USB connected mac, from my nexus 7 (as it is running 4.2.2, allegedly the version beyond which one there is this extra "security" step), which points probably to an issue associated with recognizing the device.
By experimenting a little, it looks like my plugging of the nexus 7 produces no messages in the logs ($sudo dmesg - no reaction from plugging/unplugging the nexus 7), whereas when plugging an SG3 recognized as "device" by $adb devices, produces the following output:
MTP Driver Started (Addr 0xffffff8018989800)
I assume some issues with the driver, but I could not find anything specific to mac osx. Any ideas?
