I installed lightspeed HUB, and to connecto to my TM-88V usb receipt printer. Could not connect. Closed lightpeed HUB, tried to run again as administrator, This time the application GUI will not even open. Using Windows 7 or Windows 10 makes no difference, same problem on different computers. I have to kill the program from the task manager in order to relaunch. Then got it to work eventually. What is this issue? Is lightspeed HUB flaky (prone to crashing)?
