FTDI VNC2-32l Problem

Hello friends,

have purchased V2DIP1 module and loaded V2DAP firmware via UART interface.

But i'm facing the connection problem with keyboard and mouse also. When I enquired the USB device via PC (UART interface is connected to PC by using FT232 USB module)
get the response like this

QP1#CR
#NUL#NUL#CR
D:\>#CR

which means that USB device is not connected.

Then i changed firmware and upgraded the device with USBHIDkbd.rom(ftdi demo firmware) then also I'm facing the same problem. It only gives output "waiting for enumeration" even if i connected device. Enumeration process never completed.

Also reported the problem to FTDI but not received any response.

If you guys have any kind solution then it would be very helpful for me.

Thanks in advance.

The only thing I can think of is device is not powered properly. Please check if J3 shunt jumper is shorted on the module as this will supply VUSB to the device connected on USB host port.
