Hey , I have now received the 18F4550 and the 16F1455 and have tried both with the usb_serial samples. programming with PicKit_3, but in all cases I get a warning on my PC (both on win10 and win7) that the USB is not recognized. The Vusb with capacitor reads 3.3 volts and I have programmed both with and without LVP. identical to my previous attempts. Apparently USB is not allowed to me Hans
