Windows säger "Windows has stopped this device because it has reported problems. (Code 43)" och rapporterar den som "Unknown device"
Exempelkoden från mikroelektonika funkar så hårdvaran är ok. Dessutom använder jag samma USBdsc.c så den är också ok.
Här är den andra koden:

}Så jag fattar inte varför USB'n går snett. Har ju inte rört den?
Jag har avkoppling på processorn + sändaren (100nF)
Har även kondensator på vusb (3*100nF tot 300nf)
Pullup på Mclr
EDIT:Bortkommenterad kod bort
De är väldigt tåliga så normalt är de svåravlivade om man håller sig inom rimliga gränser.
