Eeprom Writer Program Pl2303. A software tool called 'EEPROM Writer Program' is available to program this EEPROM through the. 2303 EEPROM programmer prolific. Prolific technology pl2303hxd datasheet Eeprom writer needed. I opened up the box on the cable and found the chip version was pl2303hx. Got the drivers for it and that didnt work.

However, to make matters even more annoying, the PL2303 chip, which typically identifies itself as VID 067B and PID 2303, reports PID 0609 in this device, making it impossible to recognize this as a standard serial to usb converter. The easiest solution for this is to modify the drivers so that they identify also with that PID. In Linux this and as I write this PID 0609 is already associated with the pl2303 driver by default. In Windows some inf modding does the trick. Download the drivers from the, install them and use search for the file ser2pl.inf. This will typically reside in a folder containg 4 or 5 files.
You can copy this folder as one if you want to keep it as a single 'driver package'. Inside the inf, replace all occurences of of PID_2303 with PID_0609 and use the Device Manager to assign the driver to the modem. For me, this worked in Windows XP but not in Windows 7 64 bit.
After some searching around, it seems that the PL2303 can be connected to an EEPROM chip for some customisation (just like the FTDI converter chips). Any non-standard USB PID is written in there. If you want to change it back, you need to rewrite this EEPROM. This can be done from within Windows using a tool I found on but the only prerequisite is that the device is already recognized as a PL2303 USB to Serial converter. So in my case I had to rewrite the EEPROM from within Windows XP with a modified.inf driver. Below is a screenshot of the EEPROM writer after pressing the read button on the non-modified usb modem.
Just change PID to 2303 and write everything back. You can find a copy of the tool in the attachment section under this post. Download code breaker v10 for cheat pcsx2 bios.
