Hi,
I purchased Metravi (india) DSO-5070A on 27-Aug-2013 from Lynx-India. This is manufactured by Siglent and known as SDS1072CML. Making EasyScopeX work was like hitting a wall. It was due to, lack of properly defined steps and software prerequisites in the manual.
Yesterday, after lot of R&D I figured out steps that made every time EasyScopeX work and recognize the oscilloscope on three different machines viz Windows XP Pro SP3 (32-bit), Windows 7 SP1 (32-bit) and Windows 7 SP1 (64-bit). I am mentioning those steps here to save others from wasting time and re-inventing wheel. These steps must be followed strictly.
Caution: DO NOT CONNECT OSCILLOSCOPE TO COMPUTER'S USB PORT UNTILL BELOW STEPS ARE FULLY FOLLOWED.
Warning: I am not liable/responsible, if things goes wrong at your end. Follow, below steps at your own risk.
Note: On Windows 7, run installers with administrative privileges.

7. Open Measurement & Automation Explorer.
8. Turn On oscilloscope and make sure the back USB port is set to "USBTMC" mode. Follow manual to perform the same.
9. Temporarily disable Internet connection on computer to prevent Windows searching drivers online because it eventually fails to find suitable driver for USBTMC devices.
10. Connect oscilloscope to computer's USB port.
11. Windows must recognize and install the device as "Test and Measurement Devices (IVI)". The device will appear in "Measurment & Automation Explorer" as USB::manufacturer-ID::model-code::serial-number::INSTR. Please note INSTR.
12. Finally, install EasyScopeX and ADD your device. (Reboot computer if required)
If you have followed steps strictly. I am pretty confident that EasyScopeX will show your device and ADD it easily.

1. Right Click > My Computer > Properties > Advanced Tab > Environment Variables.
