XDS200 - attempt to access the named emulator via USCIF ECOM has failed.

I'm having an issue with my Spectrum Digital XDS200 debugger. I haven't used in a few months, and now when I try to test the connection in target config I get the following message:

[Start]

Execute the command:

%ccs_base%/common/uscif/dbgjtag -f %boarddatafile% -rv -o -S integrity

[Result]


-----[Print the board config pathname(s)]------------------------------------

C:\Users\Paul\AppData\Local\.TI\1989394224\
    0\0\BrdDat\testBoard.dat

-----[Print the reset-command software log-file]-----------------------------

This utility has selected a 560/2xx-class product.
This utility will load the program 'xds2xxu.out'.
E_RPCENV_IO_ERROR(-6) No connection
Failed to open i/o connection (xds2xxu:0)

An error occurred while soft opening the controller.

-----[An error has occurred and this utility has aborted]--------------------

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.

[End]

The XDS200 shows up in Device Manager as two CDC serial ports, one Emulator and one User. I've tried to uninstall the drivers and so on without success.

Any suggestions on what I should try next?

Thanks in advance,

Paul.

    Paul,

    You did not send the CCS and the TI Emulators component releases, but I guess you may be facing a similar scenario as shown in the following thread:

    A few other scenarios are shown in section 6 of the XDS200 page:

    Hope this helps,

    Rafael

    It turns out that the issue was related to the USB hub that I was using to connect the Emulator.
    I'm guessing it may be power related since the hub is unpowered.
    Something for others to try if they run into this issue: plug the Emulator into a USB port on your computer, don't use a hub of any kind.

    Thanks for your response,
    Paul.
