Im looking to test and potentially develop support for usb to serial adapters and for console connectivity with an app similar to or with Minicom. I'm a network administrator and would be able to use my Asus Transformer or other Android tablets with USB connectors to console into the equipment I manage.
Does anyone else have interest in a project like this?
Does anyone else know of a similar project?
Thanks

I've been searching around and have found that there are Bluetooth serial apadpters with software that should allow for connectivity. Reading reviews I get mixed results.

that would be pretty cool, i am also a network manager and will proably buy also a transformer (just waiting for the new archos to see if they are anything good).
I think the rs323 cable approach would be better as there would be no power drain from the Bluetooth (i know its minumal but...).
I am new to android development (i am going to do my university final thesis based on a android software) but i would like to help
PS - if you connect a usb-rs232 adapter to the transformer and do "dmesg | tail" on a shell does it appear.
Also see if the last answer on this post helps htxxp://stackoverflow.com/questions/4621580/using-serial-port-rs-232-in-android
This is something I would pay a couple of english pounds for from the market.
My USB->Serial port adapter is based around the Prolific PL2303 chip which I think is pretty common, so may be a good place to start.
That would be amazing.
I am a network administrator and would love to see this on my device. Although I have an Acer A500 and not the Asus Transformer.
I plugged in my usb to serial adapter and ran dmesg. Here was the output :
Code:
usb 1-1: pl2303 converter now attached to ttyUSB0
Any idea of what app I could use to connect to that to test it out?

If we had full GNU utilities on Android, you could use screen against /dev/ttyUSB0 and that should connect to the serial device.
Unfortunately, I don't know of any direct serial communication applications on Android.
I'm also an IT administration and could use a working rs232 solution for my tablet.

Keyspan usb-serial adapters have drivers available in the kernel. Seems to me easiest thing to do would be to build the required kernel modules, install debian to a parition on the SD card, setup a chroot environment and install minicom/screen/serial terminal of choice. Alternatively instead of debian chroot, you could build a serial terminal client for use in the android linux environment.
Hi guys, I am a Acer Iconia A500 user but found this topic yesterday while trying to find a way to use my usb/rs232 adapter for my linux boxes at work. It seems like the only thing you need is kernel modules for the adapter you have (either prolific or ftdi) and busybox 1.19. I wrote a quick how-to for my Acer (http://forum.xda-developers.com/showpost.php?p=16703609&postcount=23) which I am also copying below. As long as you can find the kernel modules it should apply to Transformer as well:
Thanks to celsoffraga and also thor2002ro for the kernel modules, I can confirm that A500 can run a usb/serial (rs232) perfectly fine on the stock 3.1 kernel/rom.
Ingredients: Rooted, A500, kernel modules for your adapter, a terminal emulator, and busybox 1.19 which has a tool called microcom in it.
Install busybox 1.19 through this application (the other busybox installer app on the market installs a slightly different version of 1.19 that does not have microcom):
https://market.android.com/details?i...ybox.installer
Download usb2serial package for your kernel from the first post of (you can check your kernel version from Settings - About Tablet):
http://forum.xda-developers.com/show....php?t=1058713
Extract that usb2serial zip to somewhere in the tablet (I used /mnt/sdcard/modules/). There should be two files, one for Prolific chipset serial converter, pl2303.ko which is the most common one, the other one for the Fidi chipset, ftdi_sio.ko, which is what I had.
Now open your favorite terminal emulator (Both terminal emulator and connectbot works) and load the module you need, or you can load both:
Code:
insmod /mnt/sdcard/modules/ftdi_sio.ko
Now plug your usb/serial converter to the USB port, and type "dmesg" in terminal. You should see something like "FTDI USB Serial Device converter now attached to ttyUSB0" , which means everything is detected fine and attached to the correct device point in linux.
Now comes the serial terminal emulator, which is called "microcom".
In terminal, just type microcom and it should return a short help text. Our device name (TTY) is /dev/ttyUSB0 . So if I want to connect to a rs232 port with 9600 baud rate, the command should be:
Code:
microcom -s 9600 /dev/ttyUSB0
Tadaaa!
If it means I no longer have to undock and lug my massive work laptop down to the datacentre every time, I'm all for it.
fincan - awesome, can't wait to get my dock to test that out. Thank you.
Very interested in ur app, keep me posted...
Thanks

Unfortunately, my video on demand provider (in France) uses an application that checks if the tablet is rooted. I had to unroot to be able to download and watch films and catchup TV.
Is there any hope to control a FTDI interface from user space (libusb, libftdi)?
Or could I install the .ko driver so that is survive the unroot process (using the Universal script)?

ICS update?
Has anyone got this to work in ICS? If so what kernel module are you using? Tried the one from the A500 link but I get an "Invalid Argument" while running insmod
Hi all, I just installed the ASOP ICS rom on my S 4G. Love it. Beautiful and fast.
I thought I would add some music to the device, but when I connect it to my Ubuntu desktop it doesn't get recognized. The phone sees that it's connected to USB and has the options for MTP and PTP. It basically won't let me switch to PTP.
I run dmesg and it looks like it got connected:
[1121267.152118] usb 2-2: new high speed USB device using ehci_hcd and address 4
I can't seem to get it to mount though, either automatically or through mount /dev/bla /bla/bla . Any ideas?

download the dual mount sd app from the market. its free and it works. or you can use an usb storage option in your recovery(cwm and twrp).
awesome. that's what I needed to know.
thanks
This fuse solution to get MTP working worked swimmingly for me
Because I'm a new user I can't post a link to a solution that worked for me. Having said this if you google for "[How to] Connect your Android Ice Cream Sandwich Phone to Ubuntu for File Access" - the solution in the first link worked great.
Fwiw.

UPDATE-SOLVED: So I used the terminal command dmesg to see what errors were coming up relating to the usb port. It turns out I was getting the popular "unable to enumerate usb device on port..." error. From a google search on this I was able to find other people with my same problem, albeit with other types of devices not working on the usb ports. So someone tried a simple fix and worked. Ill quote it here just for the sake of keeping you on this page...
Some hardware just don’t work with ehci_hcd on Karmic Koala. My memory stick from transcend refused to work no matter what I did. After plugging the device nothing happened, doing dmesg showed me the following error:
Apr 18 10:59:04 dpac-laptop kernel: [73668.388060] usb 1-2: new high speed USB device using ehci_hcd and address 5
Apr 18 10:59:04 dpac-laptop kernel: [73668.473034] hub 1-0:1.0: unable to enumerate USB device on port 2
After searching a lot, I came to a conclusion that my device doesn’t work with USB 2.0. So I disabled the ehci_hcd to make it work.
Since Karmic doesn’t use ehci_hcd as a module, modprobe -r ehci_hcd no longer works. The module is compiled into kernel. To disable it execute the following commands in terminal:
1: cd /sys/bus/pci/drivers/ehci_hcd
2: ls
You will see a file with 0000:00:xx.x format. Execute the following command:
1: sudo sh -c 'echo -n "0000:00:xx.x" > unbind'
#Replace the xx.x with the numbers displayed on your file. It should disable the ehci_hcd.
I plugged in my memory stick, and it worked.
Please note that you’ll have to do all this each time you restart.
UPDATE
You can now use the following script to disable ehci_hcd. It is far more simpler since it just needs you copy pasting the commands instead of a manual action. Here it goes:
1: cd /sys/bus/pci/drivers/ehci_hcd/
2: sudo sh -c 'find ./ -name "0000:00:*" -print| sed "s/\.\///">unbind'
Cheers!
Ok so I just finished installing a fresh copy of Ubuntu 11.04 on my g/f's old Sony Vaio from 2003/04. I tried plugging in the Infuse to see if the computer will recognize it. So when I select 'Mass storage' from the connection menu, the connect screen with the green android robot will pop up for a split second, then disappear. So there is no way for me to mount the phone to the computer. The option doesnt even appear in the notification bar. Sometimes the robot screen wont even appear at all. I check the cable, and it works 100% fine on my win 7 64 bit pc. It just doesnt seem to want to do anything on the Ubuntu pc. The phone will charge, but thats about it. Im running the clean Gingerbread update on the Infuse. Nothing modded, and as i said, the Ubuntu is clean install as well. Ive tried this with usb debugging on and off. Ive also tried restarting both phone and pc and nothing changes.
Any help would be so greatly appreciated. Thanks a million.
weird. try other USB devices. you could have motherboard driver issues.
I'd check the Ubuntu forums and see if others with that hardware have any issues with USB devices. you may need to find some alternative drivers that aren't in the stock Ubuntu build or find a different computer.

I have tried some flash drives. They seem to work just fine. When I plug the phone in under the mass storage option, I open up a terminal and type usb-devices, and i see the three ports listed, but it shows that nothing is being detected on any of them.
Linux driver should be perfect, before connects to PC the mass storage mode should be selected.

I made sure it was selected. I also just got finished setting up the Android SDK on the Ubuntu laptop. ADB does not recognize that the device is plugged in at all. It can see my flash drives, but nothing comes up for my phone. Even with usb debugging on it did not see it. Im at a loss. Im beginning to think that this may have something to do with the Gingerbread update. Can someone with the update try to connect to Ubuntu and let me know if they have success? Ide hate to have to revert my device to Froyo or an unofficial rom to develop. =/
well I see you fixed it. did you get adb going?

are you asking how he fixed it?(he updated the op if that's what you are interested in) or how to get adb going.? adb works on Ubuntu as long as the device connects but you need to setup some device information first.
I forget the location but you need to create a file called 70rules.android (if my memory serves me right) with the vendor I.d and some other information. let me know and ill find a link on it.
Yes! I was able to finally get adb going after I had fixed the USB detection. Once I had applied the changes above my computer would immediately recognize the phone in both normal and debug mode and I could transfer files to and from it freely. Also, typing in ./adb devices finally showed my device as being connected with the proper vendor id as well.
The file I believe yyour referring to is named 70-android.rules and its only part of a whole process on getting the sdk setup on the laptop. There are a lot of hits for setting g it up on Google. There is also a whole guide for this here on xda which I had followed.

i have a usb to Ethernet adapter 10/100 which cabe with its CD. I hooked it up with my device but no luck. :crying:
could not see eth0 in terminal using netcfg .
after reading some posts about usb to Ethernet on xda , I rooted the phone, ran the makefile provided in the CD. still no luck.
So finally after reading for 2 days, I have options to
Install Ethernet drivers (don't know how)
Install kernel with Ethernet drivers (will change my phone config completely, maybe need to recalibrate later)
Flash a new ROM with Ethernet drivers (will need to reinstall everything)
Don't know the best option. Kinda stuck.
I don't want to loose the current config of cpu speed, etc. provided in the current Android
FYI: The device is detected on the device using usb host controller. Usb to Ethernet Model "Terabyte USB To Lan Card Ethernet Adapter Speed 10/100" found on Amazon. Manufacturer CH9100 Make CH9200. drivers provided has a "ch9x00.c" dunno what to do with it. (I mean after cross compiling).
attached the .c file for refrence.
I've got the FasssstJB 2.5 ROM up and running, once I got the touch screen working its been great. I've got Kali loaded via Linux Deploy and I plan on using a AWUS036H wireless for Kali.
When I plug the USB wireless in; lsusb can see the device in both android and kali however ifconfig shows nothing so I'm missing the rtl8187 drivers.
I've tried a few rtl8187.ko drivers I've found but nothing for 4.2.2
Anyone have an rtl8187.ko driver for 4.2.2 they care to share?
I'm 99.9% to my goal if I could just get this driver running
Thanks
