PL2303 with custom VID/PID

pl2303 eeprom

I want to use a PL2303 with a custom VID/PID and I know there is a (software) tool available to do that. But unfortunately it's not freely available (like FTDI on their site).

Does anyone have this tool for me, so I can test my interface with a custom VID/PID?

Thanks!

Hi

for custome PID/VID you need to purchase it from
www.usb.og

some companies sell PID within it's VID for much less price
just serch the web

If you need to edit you discreptors you need to understand the USB specs
or use ready made tools from USB.org you can find some helpful tool

If you need to build a driver
Compuware have a program to help developing drivers.
or you need to study "Windows Driver model" BOOK you can find it here in EDAborad

if your device is HID , you just need to know how to interface with hid.dll of windows ,you can many programs source code doing that

Obtaining a 'free' VID/PID combination is not really a problem, since I can buy a VID/PID combination through www.voti.nl. I don't want it in my application to be detected as a 'standard' USB-to-serial adaptor, especially since I want to use more than one of these devices on the same bus.

The PL2303 is a standard USB-to-serial converter which has a default VID/PID. If an external EEPROM is connected, a custom VID/PID can be set.

The problem is that no information is available about the contents of this EEPROM. A software tool called 'EEPROM Writer Program' is available to program this EEPROM through the PL2303 itself, but I cannot find this tool anywhere. In the past, it was freely available on the manufacturers website, but now not anymore.

When you change ViD and PID ,, then need change on driver ,, how to do it ??? I am new on it .

I know this is an old thread but I want to post here because it is related to this thread

Where is the document for PL2303 PID change or device customization.
a long time ago I seen it at prolific site but now I did't find it as far I remember Pl2303 requires 6.5V for programming correct me if I am wrong.
If any body have that documentation Please give me a link or upload.
