[QUOTE="Najas, post: 1839386"] Hi, I am using HCT 12.0 on XP SP2 to verify my USB device under Unclassified Category. On fast test machines (say 2.8GHz, HyperThreaded machine with 512 MB RAM), some of the automated test cases fails stating that device cannot be found on the bus under proper tree. On repeating the test by selecting the failed cases individually it passes. The order of failure can vary - for example if "USB address descriptor" is the first test and it passes, the next test scheduled, say "USB descriptor" fails. On later repeating "USB descriptor" by itself, it passes. I can see the same behavior on standard USB devices too if tests are run on these, say Microsoft Intellimouse. This seems more like a timing issue where the next test case starts executing even before the device enumerates and comes up over USB bus. I have two questions regarding this behavior: Is this a known behavior in HCT? Is it acceptable that cases failing, can be run successfully individually and those logs used for submission? Regards, Najas [/QUOTE]
