Java System.getProperties() on various platforms

Here is a handy comparison of Java System.getProperties() on various platforms, in case you are ever trying to detect what OS you are running on.  What is interesting is how Android reports itself as Linux, but it looks like there are some other candidate properties that will give you a clue that it is Android.

Cisco CP-DX650 USB driver for Android ADB

Grrr!  Why doesn't Cisco make their documentation easier to find?  After days of searching, I finally found the solution.  See

https://developer.cisco.com/site/tech/communication-collaboration/endpoints/dx600/overview/

Apparently, there is a developer kit called the "Cisco DX650 Add-on".  More importantly, it has instructions on how to install the USB driver.  In case that link goes stale in the future, let me highlight the salient points:

1. Install Android SDK (duh)
2. Install the Google USB Driver (duh)
3. Edit ...\android-sdk-windows\usb_driver\android_winusb.inf
4. Add the following lines under [Google.NTx86] and [Google.NTamd64]
   ;Cisco DX650
   %SingleAdbInterface% = USB_Install, USB\VID_0451&PID_D109
   %CompositeAdbInterface% = USB_Install, USB\VID_0451&PID_D109&MI_01
   %CompositeAdbInterface% = USB_Install, USB\VID_0451&PID_D109&MI_02
5. Save and close it
6. Connect the device to your PC
7. You may need to specify the location of the driver as
   ...\android-sdk-windows\usb_driver\
8. Enjoy!
