I downloaded and installed via Android SDK Manager (rev 24.2) the latest Google USB Driver (rev 11).

adb devices works well with my Nexus S G4 (Android 4.1.2) and is able to list it without any problem.

adb devices cannot detect my iRulu U2 (Android 4.4.4).

On my PC's Device Manager it shows up as MT65xx Android Phone:

iRulu's website is of no help: The list on http://www.irulu.com/DownLoad/driver is cryptic and when I finally guessed a search term "driver", it found one item:


I downloaded it but upon attempt to install it, Device Manager's wizard complains that it is unsigned.

Any idea where I can find a USB driver that works with the iRulu U2?


Answering my own question:

After much search I found this post by Koushik Dutta who kindly shared his own developed Universal ADB Driver.

In there I found the installer (UniversalAdbDriverSetup6.msi) and the source code for it.

After running it, my iRulu U2 is now recognized by Device Manager as HTC Android Interface:

Can't comment (need 50 points) so I am posting this as an answer complementing the OP:

These specifications state that the iRulu U2's SoC (system on chip) is MediaTek MT6582V/X and its CPU is ARM Cortex-A7, 1300 MHz (4 Cores).

This phone looks like a clone of "something more supported" (LG G3?), so to find a compatible driver, perhaps one has to look for a well known brand phone with specs similar to this:

  • Dimensions: 69.2 x 135.2 x 8.5 mm
  • Weight: 143 g
  • SoC: MediaTek MT6582V/X
  • CPU: ARM Cortex-A7, 1300 MHz, Cores: 4
  • GPU: ARM Mali-400 MP2, 500 MHz, Cores: 2
  • RAM: 1 GB, 533 MHz
  • Storage: 8 GB
  • Memory cards: microSD, microSDHC
  • Display: 5 in, IPS, 540 x 960 pixels, 24 bit
  • Battery: 2000 mAh, Li-Ion
  • OS: Android 4.4.2 KitKat
  • Camera: 4128 x 3096 pixels, 1920 x 1080 pixels, 30 fps
  • SIM card: Mini-SIM, Micro-SIM
  • Wi-Fi: b, g, n, Wi-Fi Hotspot
  • USB: 2.0, Micro USB
  • Bluetooth: 4.0
  • Positioning: GPS, A-GPS

More specifically, look at this Wikipedia list:


And even more specific to the MediaTek MT6582V/X:

e.g. Gionee Ctrl V5, Gionee Pioneer P4, Intex Aqua Life, Obi Boa S503, Fly Evo Energy 4. All "no name" brands, just like the iRulu U2.
