hi !
i attach a CCD Demo from MCHPFSUSB v2.2 USB Framework compiled and tested on mai board with 18f4550.
Please burn a "USB Device - CDC - Basic Demo - C18 - PICDEM FSUSB.hex"!
....when connected to USB , message shows , usb device not recognized and shows unknown device in device manager....
To modify the VID/PID in one of the example USB firmware projects, open the usbdsc.c file (found in the ‘autofiles’ folder of the project). Search for the terms “Vendor ID” and “Product ID”. They should appear in the table used for the USB Device Descriptor. Change both values as needed.
To modify the VID/PID in the .INF file, open the relevant INF file and search for the “[DeviceList]” sections. There are two sections, one for 32-bit and one for 64-bit, both sections should be identical. In these sections, some text will appear with the form “USB\VID_xxxx&PID_yyyy”. Update the “xxxx” and “yyyy” sections with the new hexadecimal format VID/PID values.
[DeviceList]
%DESCRIPTION%=DriverInstall,USB\VID_04D8&PID_000B, USB\VID_04D8&PID_000C
When you connect the USB cable with your PC and the alert of "Unknown Device" is displayed, where in the device manager is the device listed?
