I have a USB-6343. After reset I configure two of the PFI i/o to output clocks using LabView. The outputs generate clocks but only after going into NI MAX to exercise these ports before using the LabView application. The ports are tristated at startup. Is there something that needs to be done to ready the ports for output following reset?

See Setting and Reading the Power-Up States of Digital Output Lines
You can only set the state to low, high or tri-state. You cannot configure it to output a clock on reset. You must use NI MAX or LabVIEW API to tell the device to output the clocks explicitly.
If you want to output clocks automatically on startup, you need a reconfigurable DAQ with FPGA like USB-7845R.
