Hi i have just recieved a new board as my other one broke. plugged it into to my computer the red and green lights are constantly on. but the computer does not try to install a driver after downloading the driver off of the website. i unplugged all the printer cables and just plugg in the usb but still no serial port showing up and arduino software does not show serial ports either. what does the 2 usb green and red led lights constantly being on mean? please help
The red and green LED lights up if it is connected on the Computer. They goes off when you turn on the power of the printer. You have to do a manual installing of the drivers, because the printer is not P&P.
thank you for the reply… it turned out the usb cable was no good. i have a replacement board now and everything is working amazing… thank you for your time
i ment replaced the usb cable
