Arduino Tian

After using the Web Interface I am unable to use the programming USB ports. I have reinstalled all drivers and arduino software without success I can upload software by the Web Interface but only by using device at the serial number. Tian with USB address will not work. Hard resets do not correct the issue: ie holding WIFI button for 30 seconds and using the the Arduino Luci reset. I have uninstalled the device drivers several times, com 3 and com4, without success. It appears that some portion pf memory may have been overwritten?
