If you want to get help, follow the instructions and answer the questions. At the moment I don't know what have you done and what effect you achieved. It seems that you have proper drivers. It's hard to say what the other devices are, a 3G / GPRS modem probably.
Eclipse Android debugging. Eclipse is using DDMS for debugging, so probably it will not work for you either. I suggest trying another cable and another USB port in your PC. You could also try adb kill-server then adb start-server from command prompt or even manually end adb.exe process (Ctrl+Alt+Del, find adb.exe, press end process) and execute adb start-server. Ensure that your device is connected in "charge only" mode (if it has such option), so that SD Card is not mounted. Check Settings->Applications->Development-> USB Debugging on device. Do you see the 'USB debugging connected' notification on device when connecting via USB?
