The real puzzle is that the system is* almost *working. MPLAB can connect to the chip, it can program the chip in both debug and release modes. The only thing it cannot do is connect to the debug executive. This and every other reference to the errror on the web suggests that the problem is not in the USB but in the downstream cabling (there are several reports that shortening the final cables has solved this problem). But WTF should that be OS dependant? __________________________________________ David C Brown 43 Bings Road Whaley Bridge High Peak Phone: 01663 733236 Derbyshire eMail: dcb.home@gmail.com SK23 7ND web: www.bings-knowle.co.uk/dcb *Sent from my etch-a-sketch* On 31 December 2017 at 20:33, Harold Hallikainen wrote: > I think I've seen a similar message when the chip holds a production > build.
