Whenever i try to connect using scan mode i get same error-no cable found.I have found if i connect usb to laptop an ddisconnect obd 2 connector at black box fire up laptop ,open scan software an connect it finds my flashscan cable and pops up a window saying preferred cable not set to flashscan would i like to set it now-say yes ,reconnect obd2 cable to black box and reconnect,it now works.I have set preferred cable to flashscan under properties but it seems to lose it when i exit software.This is a pain ,maybe blacky or someone could come up with a fix.
