XDS200 detecting issue

Hi,

  I am working on TMS320F28335 using CCS  Version: 5.3.0.00090(90 days eval version)

When i connect to XDS200 to a USB hub in my Windows 7 PC, it is throwing the following error,


This error is generated by TI's USCIF driver or utilities.

The value is '-250' (0xffffff06).
The title is 'SC_ERR_ECOM_EMUNAME'.

The explanation is:
An attempt to access the named emulator via USCIF ECOM has failed.

I tried with all the USB hubs in my PC also I'm using admin privilege.

The driver for XDS200 is also installed under C:\ti\ccsv5\ccs_base\emulation\windows\xds2xx_drivers.

In the emulator I can see the Left LED glowing green but not the right LED.

Please help me out in fixing it.

Thanks and Regards,

Karthik Rao
