I recently bought Dell Venue 7 tablet. I am planning to use that for testing and debugging android apps. Unfortunately the usb driver for that device does not exits. I check
I just got a Venue 8 and was able to get this working. Here is what I did.
Put the Venue in developer mode - SETTINGS > ABOUT > tap the Build Number seven times.
Go to SETTINGS > DEVELOPER OPTIONS > and check the USB Debugging option
Plug it into your computer - I'm using Windows 8.1.
Open the Device Manager and locate the Android ? device.
Download the Intel Android driver, I used v1.1.5
https://secure-software.intel.com/es-es/protected-download/385047/494732
The install will fail on Win8.1, extract the EXE with 7zip
In the device manager right click on Android-Phone > Browse my computer for driver software > Choose Let me pick from a list of device drivers on my computer > Select Android device > Have Disk > Navigate to the folder you unpacked the exe and select "android_winusb.inf" > Select Android Bootloader Interface > Press OK on the warning to proceed
In the device manager it will show up at "Android Phone/Android Bootloader Interface"
Open Eclipse and browse to the Android Device Chooser and under Choose a running Android device, the option Dell-venue_8_3830-DellVenue8... should show up.
I was able to successfully deploy an app to the device.
