Windows 7 can't detect ADB device

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?

Android FASTBOOT via USB OTG?

I have a windows 8.1 tablet that only has a mircoUSB connector.
I've installed adb & fastboot drivers.
If I connect my Nexus tablet to my Windows tablet via OTG & USB Cables, it's detected fine when the Nexus tablet is booted normally.
I can run adb and browse the Nexus table without issue.
However if I reboot the Nexus tablet to the bootloader and then connect it to the Windows tablet, I get a quick connection sound and an instant disconnection.
Nothing appears in Device Manager.
Same Nexus tablet on a Windows 7 laptop or Windows 8.1 PC works fine in bootloader mode.
So what am I doing wrong on the Windows 8.1 tablet ?
Should this work via OTG ?
Is it a driver issue ? if it is how do I install the driver when nothing appears in device manager ?
Thanks

LG Optimus zone 2 adb connection problems

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 :-(.

Eclipse Kepler does not allow debugging on Samsung Galaxy S4

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.
