When I connect my pic 18f2550 to my W7 laptop it shows "usb device not recognized" message.
The pic has the sample program USB18 Mouse.
Does anybody knows where to dowload the drivers?... Am I missing something?.. Will appreciate your help.

Regards!!!

A USB mouse is HID so needs no drivers

What code are you running, one of the Proton examples?. Among a million things that can go wrong, D+ and D- crossed, Vusb cap missing /backwards, Vregen turned off.

Done... As Towlerg mention.... I wasn't using the Vusb capacitor. :sneakiness:.. once I connected it detect the microcontroller and worked OK!!..
