  • Hello, I bought one of these today and i opened the package brand new and the first thing i did was to connect it to the computer to see if it works or not. So i took one usb cable and plugged the chip to the computer and nothing happens, rx and tx lights blink one time and that was it. Computer doesn’t even show that a new device has been connected. I installed the drivers, nothig different. I tryed to see if it actually provides the 5v power so i took a voltmeter and between 5v and gnd there is 5v. Is the chip broken or am i missing something else ?

No public wish lists :(
