No USB connection, no green light

Post by K0JFF »

I recently purchased a usbtinyISP kit from Adafruit: November 11, 2020 @ 12:48 PM Order #2405876-4689517684 $28.60 Shipped: 9400111899220218043509
I assembled it carefully (see pics attached). But it has never been discovered by the PC. I've reinstalled drivers (old and new), I have tried different cables, different usb ports, different Uno boards conntected; no joy. I have read the form posts and tried everything suggested to or by others with the same problem. I have never seen the green LED come on. Now I'm wondering if I have a defective IC component? Is there anything further you can suggest? Perhaps a replacement kit? I look forward to hearing from you.
Thanks,
Jeff Evans
