Hi Team, WSPR Desktop 80-10 TX ProdNo: 2.1 1012 HW Version 1.2 My baby has been off the air for a while with what looked like the "power on, power LED briefly flashing and dying" issue. I was poking around the test points to report this when, I am guessing, something reset (or died) and stuff started working again. I have seen all the LEDS behave correctly, and it even started a TX cycle. Finger crossed. When plugging in the USB to the computer, I get an Unknown USB Device (Device Descriptor Request Failed). I have tried reinstalling various versions of the CH340 drivers and rebooting multiple times. From searching the forum, I found that my original problem may have been a dying ch340B USB chip. Does this sound like a possability, and is the fix to install a new ch340 or possibly jump in and another test chip to see? Andrew VK6WAM
