Vista - Errors while run DTM Test USB Address Description Test

Hello,
I got some errors while run USB address description test.
These are the logs of some of these errors

Case 1
TaskResult Error
Root Cause
The Execute Task with Commandline
cmd /c IF FALSE == FALSE
(C:\WTT\JobsWorkingDir\Tasks\WTTJobRun902C0ADD-E1FB-4B12-AA36-4813B7A
C6D61\usbhct.exe -a -d 0DD4/0175 -l usbhct_a.log ) ELSE ( wttcmd /ping
/target: DTM_W2K3_SRV )
Failed with ExitCode 1
Resolution
The task exited with an ExitCode other than the ExpectedTaskExitCode.
This may cause the Task to Fail if it is set to Fail On Exit Code
