I have Micromax MMX 310G USB modem working fine till recently on Windows XP. Recently, while browsing I tried to switch from Auto mode to EDGE/GPRS MODE from then onwards the device is displaying "No Device". I restarted the computer and tried to connect. Red light is flashing for few seconds and not recognized. I tried to connect on other computer also. I had the same problem of red light flashing for few seconds and not recognized in that computer also. My warrenty period is over. I have tried repairing windows XP also. Please any one help me.
