I'm trying to test an Android application and have a device connected via USB. The device detects (and charges off) the USB connection but I can't seem to find any record on the computer (running Windows 7) that the device is connected. I looked in Device Manager and did not see an "Android Devices" category, nor did I see an "Other Devices" category. I looked on the device manufacturer's website to see if they had drivers; I could not find any. Does anyone have any idea as to how I could get the device to show on the computer? Thanks!

Probably, You may forgot to enable `USB Debugging` on developer option. – theapache64 Feb 12 '16 at 18:43

@AxeFox USB Debugging is enabled in the Developer Options panel on the device. That hasn't changed from when I first got the problem. – Tyll'a Feb 12 '16 at 18:45

On which port the usb is connected. front port or backport of the CPU ?. Hope you're using PC. If it's in front port, try backport. – theapache64 Feb 12 '16 at 18:50

@AxeFox Yes, I am using a Windows PC. I tried connecting the device to the other USB port and no luck. – Tyll'a Feb 12 '16 at 18:54
-
@codeMagic The answers to that question are all about enabling USB Debugging in the developer options. It is already enabled. – Tyll'a Feb 12 '16 at 18:57
-
Yes, but at least one in particular mentions that sometimes you have to have it turned off, unplug from computer, turn on dev option, then plug back in – codeMagic Feb 12 '16 at 18:58

did you do `adb devices`? Also you can try killing and restarting adb – codeMagic Feb 12 '16 at 18:59
-
@codeMagic It was worth a try to do that. Unfortunately, it didn't work. And yes, I did use adb devices, and I did try killing and restarting adb. Neither worked. – Tyll'a Feb 12 '16 at 19:01

@codeMagic i've 1k+ rep. :) – theapache64 Feb 12 '16 at 19:42

@codeMagic I completely agree with you about switching to Android Studio. Unfortunately, for this project, I'm stuck with Eclipse. – Tyll'a Feb 12 '16 at 19:43

@codeMagic **OFFTOPICAGAIN**. it shows `Only users nominated by the room owner may talk here.`. I think, i got kicked long time ago . :') – theapache64 Feb 12 '16 at 19:48

@PSDuckie Have you tried 'Universal ADB Driver' ? http://adbdriver.com/ – theapache64 Feb 12 '16 at 19:50
-
@AxeFox I tried to install the Universal ADB Driver but it gave me an "[Error] Device not found". – Tyll'a Feb 12 '16 at 20:03

Most probably windows and especially android adb will see your android device after installing the Google USB Driver
I had the same problem for many of my android devices and most of them are running fine with the driver from google. Only for some sony devices I had to install special drivers.

I have the Google USB driver on my computer but, as I can't see the device on the computer, I have no way to install it. – Tyll'a Feb 12 '16 at 19:01
-
In this case I would reinstall the lastest mainboard/chipset driver in oder to fix potential USB issues – Chilly Code Feb 13 '16 at 17:39

The drivers on the PC. The chipset driver does wonders sometimes. If that doesn't help I would connect my android device to another PC to check against. – Chilly Code Feb 15 '16 at 21:04
-
Okay, I haven't tried the chipset drivers yet. However, I did try to connect the device to another computer. It did not work. – Tyll'a Feb 16 '16 at 14:05
-
Update: I tried to connect the device to a third computer - this time a Mac - and it didn't show up on the Mac either. I'm still extremely confused about why this is happening, and still extremely frustrated that it is still happening. – Tyll'a Feb 18 '16 at 17:46

In Android Studio go to Tools -> Android -> Android Device Monitor. Once it opens close it, this will reset your adb and you should be able to see your device

One problem: I'm not using Android Studio. I'm using Eclipse. Is there an equivalent command in Eclipse? – Tyll'a Feb 12 '16 at 19:15
-
@PSDuckie From command line go to your directory of adb, usually `cd Library/Android/sdk/platform-tools` then run `./adb kill-server` then `./adb start-server` – Bill Zangardi Feb 12 '16 at 19:26
-
I tried that, but it didn't change anything; the device still does not show up on the adb devices. – Tyll'a Feb 12 '16 at 19:36

Your problem sounds related with drivers
the Google USB Driver works only for some android models, some other drivers are installed as plug and play but some others you have to install manually.
http://developer.android.com/intl/es/tools/extras/oem-usb.html
Also sometimes it happened to me that the adb didn't recognize the device while the screen was locked so you could also check that out.

I looked at that page, and the OEM for the device I'm using is not listed. As for the locked-screen issue, the screen has been unlocked during all of this testing. – Tyll'a Feb 12 '16 at 19:37
-
That site says the list is not exhaustive, so you could try looking googling the drivers youself and/or tell us your device model so we can check for the drivers. – Edwin Feb 12 '16 at 19:45
-
Believe me, I have tried to find the drivers, mainly on the manufacturer's website. But if you want to see if you can find the drivers where I have failed, I'm using a TTX M700DM4. – Tyll'a Feb 12 '16 at 19:47
-
if you can, try with a different device to check if it is the drivers or something else – Edwin Feb 12 '16 at 19:48
-
Okay, I tried with another device (from a different manufacturer) and got the same result. – Tyll'a Feb 12 '16 at 19:52

It turned out that the USB cable I was using was a charge-only cable. After switching the cable out, the device showed on ADB.
