UCD9222: Controlling UCD7242, one rail doesn't work unless GUI is connected

Part Number: UCD9222
Other Parts Discussed in Thread: UCD7242, USB-TO-GPIO

I am using a UCD9222 to sequence/control a UCD7242.  Normally the design works fine but I am finding a few units that for the B side of the UCD7242 it will not work unless the USB adapter is connected at power up.  If I have the USB adapter connected and power the board it boots up fine.  If I don't have the adapter connected and power up the B channel on the UCD7242 does not start.  If I then connect the adapter the GUI reports a fault on the B channel.  If I do a soft reset in the GUI of the device it powers up fine.
