I have a piece of old equipment at work that i use a DOS program and a USB to serial adapter with a null modem cable to back up files off of the equipment. I installed DOS box and it runs my equipments program perfectly. Is it possible to communicate through the XOOM's USB port to my equipment using a USB to Serial adapter and null modem cable to do this with? Any help or advice would be great.
Thank You,
-Nathan
I guess I should take that as a NO!!!. I will pay to make this happen though!!

those usb to serial adapters use a Prolific chipset. Linux requires a kernel module to work with them. I suspect you'll need to build the kernel module and add a script to insmod it.
My boss will gladly pay someone to get this to work. If there are any Devs that want this project contact me and we can get this going. I know i can approve 1K to make this happen.
It can be done.
I have currently got my xoom setup so that I have a usb serial adapter connected to it for debugging purposes.
Do you know what chipset your usb to serial adaptor uses? I can then check if it is supported by the linux kernel.

I'm in. We'll start research. Sounds like fun.
Sign me up too. I would love to serial into Cisco devices with my xoom.
The following pieces of information i have already:
My usb2serial Adapter uses the prolific pl-2303 chipset
it is driven by the pl2303 kernel module.
the module depends on the usbserial module, which is already in tiamat as well as stock (its needed for the 3g modem i think)
So if i am correct we need the pl-2303 kernel module and a piece of software (minicom, cu) to use the serial (as far as i know there is no software in the market for this)
ok, i took a quick look at the tiamat git repository and it contains the pl2303 driver.
Now i am going to try to compile my own tiamat kernel
First time compiling linux for an android device
I would love to see this happen. I have tons of Cisco swithes and routers that I always have to configure on the fly. I know I can buy a bluetooth adapter but still have to power that :-( Would love to be able to hookup my otg cable, then my usb to serial, then to my console cable to configure everything.
Just not sure how to get the usb serial drivers installed on android :-(
If this ever gets working then my IT dept. will be getting a Xoom as well.
Thanks,
Ken~
Any updated news on getting this to work? Really don't want to spend $60 for a bluetooth serial adapter.

I can try and include a few optional modules for the next tiamat release for usb serial devices
This is an old thread but in case ...
I also have to do serial communication with an old printer.
For now, I'm trying to prototype with an arduino mega using a trendnet usb to serial adapter.
I'm using the sample app on the market of this lib :
http://slickdevlabs.com/slick-usb-2-serial-library/
I actually can send and receive bytes on the xoom.
The only problem for now is that characters receive or send are not correct. I Don't understnd but still searching.
Any way, it should work ...

install bt5 and then install minicom under bt5. The pl2303 module with the pl2303 usb serial adapter does this very well.
bt5 you mean "backtrack 5" ?
I must use default rom ... My customer doesn't wan't to loose it's warranty ...
And usage of Motorola xoom is sure.
It might be another tablet.
Using capabilities that only requre Android 3.1 (without root) and a USB Host allow to change of device easily.
Hello everyone,
I am taking networking classes and I was wondering if it's possible, instead of carrying a laptop with me, to use my SGS2(rooted) to configure switches/router with.
I bought a female to female usb adapter, and i also have a USB to serial cable. So all the cabling is fine, but still when I open a console emulator i get nothing going there...
I believe it may be parity related, but there seem to be no console parity settings on any of the terminal emulators that i was able to find on the market.
Usualy, if you extablish a console connection from a laptop via USB, the usb port gets defaulted to COM3 or COM4. Do android devices have a defaulted COM port to the usb connection, Is there a config file where I can change it, or is it supported at all?
any help would be appreciated,
thanks
usb webcam's tf101 mounted in my car 24x7 as a car pc so to speak.
And i'm wondering if anyone knows a way to add a usb webcam and record maybe a 1hr loop of video at 640x480+ res and say 15fps+ like a police dash cam in a way
Tablet is in a custom mount with dock so i have 2 usb ports.
Tablet is rooted and running team eos rom. It is a b70 sbv1.
I have made a few small apps to interface my tablet with my arduino over bluetooth. But thats about the best i can do
I have a small 7 tablet with a usb host bort and no cameras (tegra powered)
That i wish to use a usb cam with as well as a bike cam
As always the higher the rez the better
I have a tf201 as well
If it doesn't detect and use the usb webcam, then you're running in to the same problem I'm having with my usb headphone adapter, and will probably have to make a driver for it. If it's Plug and Play in a linux based operating system, you should be able to package the needed modules into a driver and add to a kernel. Get a terminal emulator and run lsusb with the cam unplugged, and then run lsusb again after plugging in. it should give something like this
--
Lsusb:
Bus 001 Device 001: ID 1d6b:0002 <-- These were here already
Bus 001 Device 026: ID 05e3: 0610<-- These were here already
Bus 001 Device 028: ID 046d:0a17 <--- this is the new entry after plugging in/ (headphone adapter)
--
Then google the ID (046d:0a17, whatever yours says) linux module. You'll need kernel source from asus or other base kernel to work with.
--
also try dmesg immediately after plugging in and see if any errors pop up, if not then you need a driver.
I am running ARHD 3.2.2 on a TF101 and I really need a usb 2 serial adapter to work. It appears that I need the following: ftdi_sio.ko, usbserial.ko and also the prolific usb<>serial adapter module since I use both chipset adapters.
Does anyone have a compiled version of these for this kernal?
Thanks Matt
Nobody doing anything with serial on ICS? I am a network support person and could really use the ability to console into equipment.
Please
I'm in a simaler predicament with getting a usb headphone adapter to work, android lacks many of the usb drivers needed.
You'd have to make it yourself most likely, but it's a relatively simple cut and paste from the linux drivers.
Run a lsusb in terminal emulator before and after you plug in the device, and get the id number, then look for linux drivers to port.
Sorry I couldn't be of more help.
It is my first post here, so forgive me any mistakes. I'm a newbie to Android.
I've been drifting throughout the Internet and XDA-developers forum to find a solution to my problem, but I can't find it. You are my only hope. Even original support can't help. I bought a non-branded Android device for my car in April 2014, specifically this one: (happyshoppinglife[.com] / honda-civic-android-autoradio-dvd-navigation-with-dtv-wifi-3g-p-1168[.html]). Since then I can't connect to the Internet using 3G modem.
It seems to have some tailor-made Android version, since normal tablets don't have a DVD or FM radio or wheel-buttons.
Recently the manufacturer/developer upgraded the Android to a version 4.4.2 (chinabatemon [.com] / cargpss / android-update-442.rar)
Precisely it is:
Model SNT-210
Android 4.4.2-0140516-sntb-HOMEMADE
Kernel 3.0101-gdaab9de-dirty

iGo 9.6.7.235654-Thin1.1
Manual: autoradiodvdgpstv [.com] / user-manual / car-dvd / android-car-dvd-player-cp1.pdf
Currently I have 3g modems: Huawei E220 (VID 12d1:1003, PID 12d1:1003), Huawei K3770 (VID 12d1:14d1, PID 12d1:14c9), ZTE MF626 (VID 19d2:2000, PID 19d2:0031), Huawei E230 (VID 12d1:1003, PID 12d1:1003)
Wifi works fine, but I need 3g..
[EDIT]
I have no root access:
1|[email protected]: / $
after doing "su":
[email protected]: / $
I'm probably unable to root the device because I cannot connect to it (I got a cable: USB type A - USB type A, but it didn't work: no response from Android device nor from my laptop). After clicking "Build number" once (in the "About CarDVD" menu) it shows "No need, you are already a developer", but there are no "developer options" in the Settings menu.
There is the app "3g reconnect" already installed in the system, but after I connect a modem (E230, E220 or K3770) with working SIM (no PIN) in "Plus" (MCC 260 MNC 01) its LED is blinking green, and then blue after a while (one blink per 3-5 sec) but the system remains unchanged. The support (the Chinese via chat, not very nice experience talking: an hour waiting for response) said I .
I tried PPP Widget to help me, as well as Android Terminal and Slick USB 2 Serial Terminal.
I set PPP widget to start manually, set APN to "internet", left number to dial unchanged, no user, no password. After booting without 3g modem, PPP Widget starts and I connect the modem to a USB port. I click on the PPP icon, choose my E230 modem (12d1:1001) and I click connect. PPP Widget searches for the port and tries to connect.
When I turn on logging, portcheck.log says:
== START LOG ==
PPP Widget version 1.3.3

When I check the Android Settings (Mobile status) there is:

When I turn Android Terminal it goes:

Bus 001 Device 005: ID 04e8:6860
Sometimes There is Bus 001 Device 005 instead of 007 by 12d1:1003
When I try to use Slick USB 2 Serial Terminal it connects to the modem and answers all the AT commands:
ATI

(1,"Plus","PLUS","26001",0), (2,"Plus","PLUS","26001",2) ... {and other}
AT+COPS?
0,2,"26001",2
I can swich the modem's mode:
AT^U2DIAG=0
the default was AT^U2DIAG=257
After switching to AT^U2DIAG=0 the modem seems to be recognised by lsusb as 12d1:1001
I tried to connect manually:
AT+CGDCONT=1,"IP","internet"
ATD *99***1#
.. and it returned CONNECTED
but when I went back to the home screen and tried to check if there is Internet access (I turned on Chrome), there was no Internet access, but I have to revise this once more.
hi i'm italian and my english is bad, i've buy your same model but i have some problems because i've a short manual only for radio,bt,cd parts.

HI, alfonso.
Answering to your questions:
1) I've had many problems, which I had to solve mysfel or using chat-support (It was not a pleasant experience, each talk lasted forever..)
2) There is no "a complete manual" for SNT-210. I can only share the one I got from Happyshoppinglife => Manual
3) Changing logo: there should be an application to do that, but in my case the user should enter a password, which was "121212" and could choose the logo for your car
4) I had the issue with downloading the contacts from my phone via BT either. I didn't resolve it, I just quit doing that (downloading contacts). The problem was probably too much records in the phonebook. But synchronising the Android's phonebook with Google Account might be a solution. But.. there is a 3g / wifi connection required, which I still don't have.
Sholud you have any more questions, don't hesitate to write.
Regarding the 3g connection problem:
I am still struggling with the 3g modem case. I found out (thanks to arnoldziq) that my 3g modem is ok (there are modem drivers in Android 4.4.2, Android finds the modem and the usb port the modem is attached to). All the problems may result from a wrong APN list in \system\etc\apns-conf.xml. In my case there is
Code:
<apn carrier="PlusGSM" mcc="260" mnc="01" apn="internet" type="default,supl" />
but it should be
Code:
<apn carrier="Plus" mcc="260" mnc="01" apn="internet" type="default,supl" />
But the next problem is - it is not editable (the device is not rooted). And I tried to root the device using a shor tutorial by an XDA user KID52 for a similar device. I connected both: the device and my laptop to a router so that both devices see each other (ping confirms that). I installed ADB ("15 seconds ADB v1.3.exe" from here) on my laptop. Then I tried to connect. In my cmd (laptop) I run:
Code:
C:\Users\Grreg>adb connect 192.168.170.3
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
unable to connect to 192.168.170.3:5555
C:\Users\Grreg>adb devices -l
List of devices attached
C:\Users\Grreg>adb tcpip 5555
error: device not found
I tried to install adbWireless.apk in the CarDVD device and run the commands again. Without chnage. I read that in order to use adb via Wifi / TCPIP you have to be connected with an USB cable. But I tried, and I can't do it - neither device noticed the connection with USB type A plug - USB type A plug cable.
A question to XDA users: is there an alternative way to root the device? Or am I doing something wrong?
Hi, thank for your assistance
now I'm having another problem, the car is connected to an external display, if I insert a USB stick containing a movie in automatic start a program to read music only, if I use an app for Android naturally from the external screen is impossible see anything ... is there a way to watch movies from usb directly with some programs of the car without using the app of android?
In fact there is a program for dvd....a program for aux in....a program for usb and a program for sd card (this last I have not used yet, infact I don't know is a program for music or movies ...I hope the second!!)
You know something about?
Scuse me for my bad english
thank you

Hi,
what do you mean by "external display"? my device (youtube.com/watch?v=sEJMvUQhTJA) does not provide an option to connect an external screen - no DVI/HDMI output (maybe some AUX out, but I did not check that) - what would you need one for?
After iserting an SD card (or connecting a USB plug with SD reader or USB Flash memory) Android autimatically turns on a music app, but if you want to watch a movie, just close it and browse to the sdcard / flash using for instance "ES File Explorer File Manager" (I had it preinstalled), then when you see your file, click on it and choose an app you want to opent the file with, MX Player is one of the most popular (I had it preinstalled). is that what you needed?
i have your same software but the car device is different, i can connect an external display for person behind for example, but if i use an app of android to red movies on usb the external display doesen't receive nothing; infact if i use dvd ,or tv connet on aux ,i riceive them on external display.
Is strange that automatically device usa a program only for music fo usb or sd card....is not possible to instal a program (no app android) for use them to see movies?
I found a Russian forum where they've been discussing about this device, there is a lot of information and they are way ahead of us, the URL is
