USB Driver for PL2303 serial adpater

Hi everyone,

I'm working on a USB driver for PL2303 based serial adapters.
I got a primarily version working:

See a Video on a qemu system and patched Termie, capturing the serial output from my X5000

I'm wondering if anyone else is interested in such a driver, and help to test it to get it working in even other scenarios?

@MightyMax
Is it OS4 driver, so to be able to grab serial output from one os4 machine to another via usb2serial cable ?

I am in as always :)

@kas1e

Yes it's a OS4 driver, I thought that was clear beacsue of selected forum.

A lot is taken form the (link->:) linux sources, so any found vendor/product id should work, or at should be doable.

Do you have an PL2303 based Serial-USB adapter? And if so what Vendor/Product Id does it have?

@Max
My one:

Vendor: Prolific Technology, Inc.
Product ID: 2303

Called on box as "Prolific PL2303"

If it PL2303HXD, PL2303TA, PL2303GT or plain one i not sure, but at least in usb info i have: vid_067b&pid_2303, so should be casual one probably.

@Max

I do have a Prolific one too and and could test with 2 more.

Edit: Update 2 of course! Whishfull thinking, I thought I have Update 3 already! hahaha

finally! Well done mate!

Hi all

I also have the same USB->Serial converter

FT231X USB UART:

Product ID: 0x6001
Vendor ID: 0x0403 (Future Technology Devices International Limited)

Hi,

the following dongles use a different chip and won't work with this driver:

FT231X USB UART. -> uses FTDI chip
USB2.0-Ser! -> uses CH340 chip

The other mention should work. I will polish my driver a little bit more and provide it for testing. (Takes some time)

Those chips can be used with libftdi

I have this one inuse today:

Device Descriptor:
bDeviceProtocol 0
bMaxPacketSize0 8
idVendor 0x0403 Future Technology Devices International, Ltd
idProduct 0x6001 FT232 Serial (UART) IC
bcdDevice 6.00
iManufacturer 1 FTDI
iProduct 2 FT232R USB UART
iSerial 3 AB0JHMGG

I'll see if I can dig out some more.

Cheers,
Bill
