ccs ex_usb_serial.c and xp driver

[Ken Johnson]

Built ex_usb_serial.c, with small mods for the microchip usb demo board (changed the led and usb_available pins). Program runs ok on the pic, monitoring serial rs2323 output with siow.exe. When I attach the usb cable to the pc, the monitor reports that. But windows says new hardware found and wants to install a driver. This is XP, SP2 (and all other windows automatic updates). I thought that this was a generic cdc usb gadget, and that xp sp2 had a generic driver for it, so that no additional driver is needed.

Anyway, I tried pointing the installer to "C:\Program Files\PICC\USB Tools\WinXP" (which I thought was the ccs driver), but it said "no driver found".

I know there is some simple answer to this - can someone enlighten me please?

Many thanks,
Ken

Windows, doesn't distinguish the 'driver', from the .inf file needed to say what driver to use. For the CDC device, it has the driver present, but doesn't 'know' this, till the .inf file tells it so.
The .inf file, is in the 'drivers' directory, with the PIC code.
