UsbSerial library - Supports FTDI, Arduinos and other USB serial devices

Hello Erel,

I don't know what did happen but it don't work anymore. I got this error message on the filtered log:
On the unfiltered log I have this:
Do you have an idea ? I'm not 100% sure but I believe I was not on version 2.50 when I first try the library.
Thank you.

ft311d ftdi usb chip

Hi
i made the sw for the ft311d
it works but i needs ti be better.Maybe Erel can make a lib!
Now i'm trying to use the usbserial library and i have some question
1)i need to "Enable USB-Host Controller on any Android
i can't write the line in that directory! wich is the best apk or other way to write this line?
2) how did you connect the ft232r to a phone? i tried with an adaptor from the micro usb to the normal usb but obviously there is no vcc....
ciao

Please do not post duplicate questions.

Erel,
Thanks , I made a complete installation and now I am available to compile and run on my Samsumg Note 1 , but I am not able to communicate from my Note to serial device with FT231 , I just have program running on device no errors no activity , do you know if somebody made a try on S Note ?
Any suggestion will be welcome
Thank you

Did you check the logs for any message?

There is a wiki in the open source project with the list of supported devices.

Erel,
I got this on log , but i suppose this is related to PC emulator not device ?

Thanks you

This library will not work with the emulator.

Erel,
Thanks , do you know if it works on Samsung Note I device
Merci

It is not in the tested devices list: CompatibleAndroidDevices - usb-serial-for-android - Android devices compatible with usb-serial-for-android. - Android USB host serial driver library for CDC, FTDI, Arduino and other devices. - Google Project Hosting

It doesn't mean however that it is not supported.

serial lib

Hi
I'm trying to get the serial lib to work!
I'm using an otg cable
Now i see that the ft232r is present (usb host controller) but the software still doesn't connect.
I connected for a try a memory card reader and it works!
Any way to resolve the problem?
ciao marco

Which message do you get? Are you using Android 3+?

Hi Erel
i get "Error opening USB port"
the phone is a galaxy chat bt5330
the pnone work as accesory mode
It also reads multimedia with an otg cable
So it looks that usb is working
I tried the usbserial lib with a samsung note and it works just fine!
I'm getting crazy:BangHead:

It is possible that this device doesn't support the FTDI driver.

Hello cp2102 works ?

Hello! cp2102 works ?

It is not listed in the wiki. Will probably not work.

Hello Erel,

Any chance we can get the updated version of this library. 2 days ago they added support for cp2102 device.

Thanks

Are you sure? Seems like the latest version is still v010.

Have a look here for the changes in source.

Source Changes

Maybe it is still in development.

You seems to be right Scantech, the device_filter.xml file as been updated with the CP2102 VID, PID. http://usb-serial-for-android.googlecode.com/git/UsbSerialExamples/res/xml/device_filter.xml
But only updating the .xml file don't work in B4A.
