I have a Prolific 2303-based USB to serial adapter that I've used before with my Galaxy SII on my tablet with the keyboard dock. The device is detected according to dmesg, and is attached to ttyUSB0. But, all of the serial communication apps I've tried can't find it. There is an error with the Slick apps that says it could not find all necessary endpoints. Is anyone else using a cable for this purpose with their tablet? Care to share app, rom, kernel info? I'm using the nightly CM10.1 build from today(3/12/2013).

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.
I have been an I.T. support engineer for 15 years or so and love a challenge. Consequently my departement director gave me one to see if I could figure it out before our HQ I.T. could. It is annual review time so I naturally accepted the challenge.
Challenge - Connect an Android Tablet to a wired ethernet connection and run a speed test on the wired connection.
We have a Samsung Galaxy Tab 10.1 (model GT-P7510 to be exact)
Android version - 3.2
Kernel Version - 2.6.36.3
USB Debugging mode is enabled
Unknown sources (install of non-Market apps) is enabled.
Purchased a Samsung EPL-1PL0BEGXAR USB Connection Kit for the Galaxy Tab 10.1
Purchased a USB RJ45 Ethernet 10/100 Network Lan Card Adapter
(cant post links yet but search for "New USB RJ45 Ethernet 10/100 Network Lan Card Adapter For Apad E11 Haipad")
When you connect the USB RJ45 device it is not recognized.
To ensure the USB was working I verified that a USB thumb drive was recognized and files could be accessed.
The USB RJ45 device came with a CD with drivers for various OS including what appeared to be Android as they had indicated on their website that this particular tablet could work with the device. (DRIVERS ATTACHED AS ZIP)
Apparently it may be a usb2net type device from what I could determine looking through the files.
As I am a complete novice at Linux, Android etc I did not know what to do with these files or how and where to copy them to on the Android Tablet.
I spent free time over the past couple of weeks looking through forums and even downloaded Android SDK Manager and read up on what adb was and was able to use a command prompt to browse the device folder structure.
So, as I have a crazy week and then off for xmas break I and am turning to the experts and asking for your advice.
Any help you could give would be greatly appreciated
usb2net GT-P7510
Hi,
I can see your post is quite old... but I'm in the same case :
"Looking for a way to connect my Galaxy tab 10.1 (GT-P7510) to a wired ethernet"
I have the usb2net cable (usb to RJ45) but this connection is not recognize by the GT-P7510 ... is there a way to update the firmware?
I've seen the the galaxy tab 2 recognize the ethernet connections.
If you or someone founded a way, could you explain please.
Thx a lot.

It is not possible on that model. Hardware does not support it so suggest you do not waste more time like I did
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.
Hi!
I've rooted my Ace2 and tried to get USB OTG to work in order to connect external storage and to use DSLR Dashboard. USB Host diagnostics gives the following information (s. attachment). Neither external storage nor DSLR dashboard works. Is there a way to activate USB-OTG by editing config files? In that post I've read that the /etc/volt.fstab hat some lines commented out related to USB OTG.
EDIT: Replaced wrong screenshots
Any ideas? Wrong forum? Any suggestions?
You are using a specifically OTG cable to connect?
The cable must ground the ID pin on the USB connector of your ACE 2.
Many devices will work correctly (and automatically) when they receive the interrupt from the grounding.
See if you can get a USB keyboard to work first.
I used this (Amazon de Product B0068CEUAA) USB OTG cable.
I am not sure but in another post on xda I read that one need a new kernel where usb otg support is compiled in. I checked dmesg while connecting an usb drive, nothing happens there.
Has anyone with any USB OTG cable got this function to work on the Ace 2 (GT-I8160)?
Hi,
I'm trying to learn about serial communication with devices from an Android tablet via USB host mode. I have a tablet, I have the devices, I have the apps... they just won't talk. It's most likely something to do with the firmware on my odd tablet, or maybe I'm just missing something stupid.
The tablet:
SUPERPAD FLYTOUCH
10.2" >24GB< ANDROID 4.0 TABLET A10 1.5Ghz CPU | 1GB RAM
"About this Tablet" says:
Model: BC1003
Android 4.04
Baseband ver 1.5rc4
Kernel 3.0.8 [email protected] #2 Mon Aug 6 15:23:31 CST 2012
There are 2 USB-A ports on this device. One has a physical switch that goes from device to host mode, comes with a male-male cable for attaching to a PC. The other port is host only. I can connect a USB thumb drive and it mounts just fine, shows up in the file manager, no problems. Same for a USB keyboard. It powers any USB device I've plugged into it.
The problem:
It works well enough for most things. But, I've now run into two applications that won't use the host USB port on the thing. Both seem to want to do basic serial communication. At this point, those 2 apps are about the only things I actually want to do with it, so I'm willing to experiment.
I have a USB oscilloscope that comes with an Android app. The app installs and runs fine, but it won't recognize the hardware usb device I've plugged in. Annoying, but I don't really need it. I've recently purchased some digital scales(DROs) for my lathe/mill. There's an Android app that interfaces these scales to an Arduino device via USB. Installs fine, won't connect to the Arduino. Okay, now this is starting to get annoying. Also, for what it's worth, the Android app for doing general Arduino stuff didn't work either.
So, the USB hardware works enough to connect a USB thumb drive or keyboard but the firmware won't use said hardware to do what I want.
The questions:
Am I doing something wrong? Is there an app I can install that enables serial communication over USB host mode? Am I missing something stupid?
Is there any other firmware I can run that will allow this communication? I think I've got the Windows utility that will allow me to flash the rom. I've watched the youtube vids on dis-assembly so I can pull the internal tf/sdcard and make a full dd backup. I'm assuming it contains the roms and everything else. Actually, I'm thinking about just pulling said card and replacing it with a smaller one for experimenting. Will I still be able to flash it using the windows LiveSuite utility even with a blank card inserted?
At this point, I'm willing to play. I mean, it's still useful enough to be careful, but I'm willing to take some chances and put a little work into it. If I can get it running with the DRO software while talking over USB to the Arduino, I'd sacrifice everything else. GPS, battery life, wifi, screen rotation, sound, whatever. I'd just bolt the thing next to the mill and that's that. Failing that, I'll put it back to stock and stick it on the fridge for my wife to look up recipes, Yeah, poor tablet... motor oil and metal swarf or cooking oil and flour. No happy retirement for this tablet, sitting in a drawer gathering dust.
Any hints, links, recommendations, or directions appreciated.
David...
