Hi, Sai

We don't support this usage. Such usage model needs a Ftdi driver in Target 
BIOS.

Thanks
Feng

Hi Tian,

The host is fine, how about the Target? The problem is with the Target the 
Laptops/pc no more serial ports, so using the USB adapter?


Thanks
Sai

For Usb2Serial cable, we support the usage that the cable's usb end is 
connected with Host and the cable's serial end is connected with Target.

By this way, Host will identify a new COM port when connecting this cable like 
above. UDK Debugger will treat it as a real serial cable to access.

Hi,

Need small clarification, to connect to Host running WinDbg/UEFI debugger tool 
, do we have support for "USB->Serial Adapter" on Target ?

What I see "DebugCommunicationLibSerialPort" is hardcoded to 0x3F8 base 
address?  Unfortunately some of the DELL laptops, doesn't have serial port or 
usb debug ports? So wondering if we have support for USB->Serial adapter 
attached to "FtdiUsbSerialDriver".

Thanks for your quick response.
Sai
