That can happen if one of the data pins are not connected.

I am working with an ARM board , there is a USB serial section .I have used
Ft232Rq .
Due 32Qfn pack i somehow soldered with a DIY hot air pencil.
I have run the VCP (virtual com port) driver setup in vista .
While i plug in the board with USB cable , laptop says
" USB device is not recognized ,either it has malfunctioned , try
replugging.."
I get a USB symbol immediately i plug in the chip .
The usb symbol if i click shows "USB root hub" also "2ports"
I think it is sending the initial databytes to laptop to recognize.
is it the driver problem or some pins not soldered thats why wrong data the
FTDI chip is sending
