using USb with PIC18F4550

[kirstom14]

Hi,

I am using Flowcode v3 and I am trying to interface the 18F4550 with the PC through the USB.

I saw the video tutorial about the USB and how to install the drivers, etc. But I am having a problem:
Windows Vista is not accepting the driver that I generated from the USB component. It is saying that
"The best driver software for your device is already installed" and that the driver software is up-to-date.
But still the PIC is being seen as an Unkown Device!!

What shall I do??

Thanks
Kirsten

Try changing the PID/VID combination in Flowcode and create a new set of drivers.

Alternatively, open Windows device manager and select to uninstall your device and then reinstall it by pointing it manually to your generated INF file.

Hello

The USB serial component in V3 generates a driver that is not compatible with Vista. If you send me the flowcode program then I should be able to create you an up to date driver for your device in Vista.

Here is a Vista compatible driver that will work with the default USB serial settings. Eg keeping the PID, VID, Devicename and manufacturer as is in the USB serial properties.

Hi, sorry for the long delay.

The driver that you have sent me didn't work either, and so I bought the ECIO module. And it is working fine.

Now I need to communicate with the ECIO using C# through USB. Do you have any idea of how this can be done??

Thanks
