I bought an Android phone and the vendor does not offer any drivers whatsoever. The Android SDK and the drivers that come with it don't seem to work with the device, but the device itself reports as Android 2.2.1. 

Other users have reported that the drivers of the Nook Color worked for them, but I cannot confirm this, after trying.

What options do I have to connect to the device (and ultimately to root it)?

Is it truly just the .inf file that I need to manipulate in order to make the device ID known to Windows? After all there are tools to figure out those strings while the device is connected (although "unknown") ...

The model in question is a **Simvalley SP-60 GPS**.

*Note:*
The OS I need drivers for is either Windows 7 x64 or, if anyone has successfully done that, Windows XP 32bit (under VMware with the USB device connected to it).
