NI Max "loses" instruments when test is uninstalled which forces a reboot next time the test needs to be run

Brian,

I think I stumbled on the issue. We have a NI USB 8451. An error in the sw resulted in powereing down this device for 100 mS roughly every second, 70 times per test run. My theory is that the NI max/ Microsoft link that reloads the driver everytime can't keep up and eventual I get the NI max error. Hopefully I can get tester time tomorrow to verify this.

Thanks for the help.

Brian,

I think I stumbled on the root cause. We have a USB 8451 I2C device. A bug in the code resulted in this device being powered down for 100 ms 70 times during a 80 second test. My therory is that the NI max/microsoft link that loads the driver can't keep up and eventually NI max hangs. Hopefully I can get some time tomorrow to verify this.

Thanks for the help,

Pat
