Support for PL2303 devices

GoogleCodeExporter commented 9 years ago

Would it be possible to add support for PL2303 USB to serial devices to your 
library? I found some sourcecode for PL2303 devices in this project:
https://code.google.com/p/indiserver/source/browse/INDIserver/branches/version2#
version2%2Fsrc%2Fde%2Fhallenbeck%2Findiserver%2Fcommunication_drivers

Can you recommend or provide a sample PL2303 device?  While I can't guarantee 
when I'll get to it, having a sample device would be a prerequisite.

For instance you can use this PL2303 serial port adapter: 
http://www.aten.com/products/productItem.php?model_no=UC232A
But every adapter with the PL2303 chip should work also.

I'm trying to interface an ND-100S GPS dongle which contains a PL2303, so I 
would be very happy to test support for this USB to serial device.

Update: I have a PL2303 device on order.  I will update this bug when I have a 
chance to write/test drivers (probably in the next week or so).

I am looking forward for your update... currently, I am trying to read data 
from a gps dongle too, but I am not able to read from the device.

Would be great if Prolific chips will be supported! How's the update going?

Prolific support would be great, many serial port adapter use this chip.

The python library "pyftdi" contains a PL2303 driver (LGPL license):
https://github.com/eblot/pyftdi/blob/master/pyftdi/pyprolific/prolific.py

Are you working on a driver? If not, I would volunteer for porting the pyftdi 
prolific driver to usb-serial-for-android.

Check the project clones.
https://code.google.com/p/usb-serial-for-android/source/clones

I believe PL2303 are already implemente on some of them like :
https://code.google.com/r/serge-usb-serial-for-android/

I havent tested yet, but I will give it a shot next week.

I looked at the PL2303 file. There is no implementation of the read/write logic

I ported the pyftdi driver to usb-serial-for-android in my clone:
https://code.google.com/r/felixhaedicke-usb-serial-for-android

It is in an early development stage, but it works for me. Feedback is 
appreciated.

Cool. I'll give it a spin. Any idea if older Prolific chipsets are supported?

There is now a branch in this repository, "device-pl2303", which incorporates 
Felix's changes.  Please give it a try.

Hi Felix, I tried your port but I get an error. I will try to get the log. 
I have only one USB on my tablet, so I can't connect it to my pc for debugging 
and usb-serial at the same time.

Hi
You could try debugging over tcp:

Thanks, I did it. Was a permission problem.
The version from Felix is working fine with a cheap USB-Serial PL2303 converter 
from China.
Thank you very much!

The implementation should work with non-HX PL2303 devices. Unfortunately I do 
not have such a device. So if someone here has such a device - I am very 
interested if if works or not.

@Felix - works for me. Thanks a lot!

To Felix
(I am new to everything:-)
I cloned your clone 
https://code.google.com/r/felixhaedicke-usb-serial-for-android/
but gets the following errors when try to build(imported into intelij):

1.In the example app: 
java: method probeSingleDevice in enum 
com.hoho.android.usbserial.driver.UsbSerialProber cannot be applied to given 
types;
  required: android.hardware.usb.UsbDevice
  found: android.hardware.usb.UsbManager,android.hardware.usb.UsbDevice
  reason: actual and formal argument lists differ in length
2. In the library:
java: cannot find symbol
  symbol:   method close()
  location: variable sDriver of type com.hoho.android.usbserial.driver.UsbSerialDriver
---
I have no problem running the original from Mike

Any idea ?

I am getting similar errors with freshly imported code, not sure how to deal 
with it...

I agree/ +1 on supporting prolific devices.

Prolific them selves have already released Android driver, It shouldn't be to 
hard to Incorporated

I was able to get Felix's PL2303 code working with a small fix in the library 
(an error with thowing an exception picked up by Eclipse) and with several 
changes to the sample program to change sDriver.open() to 
sDriver.getPort(0).open() [and the same changes for .close and .setParameters] 
and the passing in of UsbManager to Open().

These changes seem to be from the Multiport refactoring.

For anyone using Aten UC232A. This converter works with the prolific driver and 
the felix clone but it has a different Vendor and PID. If you want to use this, 
you should make a few changes to the library. 

On UsbId.java you must add the Aten VID and PID

    public static final int VENDOR_ATEN = 0x0557;
    public static final int ATEN_UC232A = 0x2008;

On ProlificSerialDriver.java you must add this VID and PID to the supported 
devices.

    public static Map<Integer, int[]> getSupportedDevices() {
        final Map<Integer, int[]> supportedDevices = new LinkedHashMap<Integer, int[]>();
        supportedDevices.put(Integer.valueOf(UsbId.VENDOR_PROLIFIC),new int[] { UsbId.PROLIFIC_PL2303, });
        supportedDevices.put(Integer.valueOf(UsbId.VENDOR_ATEN),new int[] { UsbId.ATEN_UC232A, });
        return supportedDevices;
    }

On your project device_filter.xml you should add the VID and PID

    <!-- 0x0557 / 0x2008: Aten UC232A -->
    <usb-device vendor-id="1367" product-id="8200" />

Hi Hugo,

I made all the changes that you suggested but the example is crashing when I 
tap on the device entry in the list. I found that it crashes at 

sPort.open(mUsbManager);  //  line 135 examples/SerialConsoleActivity.java

Any idea what could be wrong? My device's vendor-id and product-id are same as 
you mentioned.
