ST-LINK : COMM TIMEOUT

I am using STVD 4.3.1 with ST-LINK and windows 7 32bit.

Most times I try to enter debug mode I get COMM TIMEOUT ERROR.  Clicking STOP and trying again just results in the same error over and over again.

The only way to clear the error is to unplug the ST_LINK form the USB, restart STVD and power cycle the target ( not sure if this is necessary ).

I have seen other posts reporting the same problem but with no solution.

I have upgraded my ST-LINK to the latest firmware and upgraded the windows driver but the problem persists.  I think it started when I upgraded STVD.

Anyone seen this problem / solved it ?
