Sachin,
I assume that the cable you are using has a rectangle box in between. If yes than this is a Serial cable with a USB interface. That means the first half is a Usb to Serial convertor & 2nd half is serial cable for LG phone.
I have PM you the drivers. First install the PL 2303 driver which is for Usb to Serial convertor, which will recognize your cable. don't connect the phone yet. Then install the serial driver of LG RD 5130 which is actually a rconnect dialer for LG5130. Follow the instructions & connect the phone when asked to. At the end it will says that the driver is not installed, but just ignore that & re-start you PC. This is really strange but this is how it worked for me.
Then Once you install these drivers as per my instructions, you will not get this error "USB port not found" again. Remember to uninstall any other drivers you may have installed to facilitate a clean install.
Hope this helps.
Thanks.
Hi Yunus,
I am also facing the same problem. The CD does not have the serial cable drivers. The cable I am using is for LG 7230/6130/6000. Please send me the link for the serial drivers you were refering. my email ID is sarath.gollapudi@gmail.com
Thanks,
