I have purchased an lg optimus zone 2 to develop on and I have removed all of the drivers for the phone on my windows 7 machine. I downloaded the OEM driver from LG and disconnected my network. After installing the OEM driver I connected my device to my computer ( and I have already enabled developer mode on my device and selected USB debugging), but when I run adb devices it says that no devices are connected. Clearly it is installed on my machine because it compmgmt.msc it says that it found the LG Android MTP, and on the device itself it asks me for internet connection/ mtp/ camera or just charging mode. ( I always select the MTP mode). I for the life of me can't figure out why it won't connect (I'm trying to test an app locally on the machine), maybe I should stick to iPhone development :-(.

I am trying to develop an app and test it on my android device, however my computer can't seem to find the device. On the phone developer mode is unlocked, usb debug is enabled, and usb configuration is set to MTP (Media Transfer Protocol). I have android studio installed on my mac and with the device plugged in running adb devices returns that there are not devices attached???
This is an odd one. When I'm at work I have my Macbook Pro plugged into a monitor, which has built-in USB ports. I plug the USB from the monitor into my laptop, and then plug Android phones or tablets into the monitor. This works great and there are no problems running or debugging using ADB.
However, if I plug devices directly into my laptop they will not be detected. They receive power but do not show up in ADB. I have tried the following:
Rebooted the laptop
Killed and restarted ADB
Installed Android Studio updates
Used all USB ports on the laptop
Used different USB cables
Used different USB devices, spanning all Android versions
What gives? I am running High Sierra 10.13.6. Any ideas? I can post more information if needed but I'm not sure what will be helpful.
If I plug in LG Nexus 5X to computer with Win7. I see only one device. It's MTP.
USB\VID_18D1&PID_4EE6&REV_0310
USB\VID_18D1&PID_4EE6
But when I plug in the device to computer with Win8 the system detects 2 devices:
USB\VID_18D1&PID_4EE6&REV_0310&MI_00
USB\VID_18D1&PID_4EE6&MI_00
and
USB\VID_18D1&PID_4EE6&REV_0310&MI_01
USB\VID_18D1&PID_4EE6&MI_01
One for MTP device and other for ADB device.
So. How can I detect 2 devices on Win7?
I have a htc device on android 4.1.1. I have installed htc drivers, but the device is not listed as plugged into a usb. The device starts charging when plugged into usb - the cable is fine. What else could be causing this issue?
If you are on windows try installing the android universal USB driver
If you are on MacOS you need android file transfer
If this doesn't work try changing USB port and make sure that your device is conected as Mass Storage.
I'm using a Samsung Galaxy S4 I9505 (Jelly Bean 4.3) as my debug target, and I've done the preliminary steps already:
Tapped 7 times on the "Build Number" under "My Device" to enable developer menu
Enabled USB Debugging from the device
Unchecked the "Verify apps via USB" to make sure my app is not blocked
Downloaded the OEM driver for Samsung from Samsung Andorid USB Driver for Windows
Installed the driver successfully.
When I connect my device via USB, Eclipse sees my device but does not allow me to debug on it.
Can someone help me?
If you're developing Android on Windows, then Windows may have allow you to "see" your device. But to connect to your Samsung Galaxy S4 I9505, you may need to install the Samsung USB drivers for mobile devices v1.5.33.0, which can be found here.
After installation, you may need to restart your computer. Once the computer has restarted, start a command prompt and navigate to \android-sdk\platform-tools. Then, type each command below in succession:
adb kill-server
adb start-server
adb devices
The last command will tell you whether you are truly connected to your device and the device is ready for debugging in Eclipse.
