Pic 18F4550 USB problemas de comunicação.

[iFireOxz]

Tudo bem pessoal? Estou com um problema. Estou fazendo um projeto que lê informações vindas de um sensor e joga para um software no PC através da USB, estou usando HID para mandar. Segue abaixo o código. O meu problema é, quando compilo, coloco a usb ele não identifica nada, como se nada estivesse sido plugado, alguém ja possou por isso ou sabe arrumar? Tem algo de errado com meu código? Estou usando o MikroC para compilar.

O problema ja foi resolvido, o MikroC estava com um crack bugado e gerando um .hex todo errado, identifiquei isso olhando as possições de memória pelo PicKit2, pode fechar o tópico
