USB Host mode on Defy

Has anyone tried Defy's USB Host mode?
Would like to attach USB devices onto Defy:
- USB keyboard / mouse
- USB disk drives
- Other types of USB 3G modems (like CDMA1x/EVDO)
- Arduino IO board
...
I haven't bought Defy yet, but want to do some pre-research before the purchase.
Could someone do me a favor to post the outputs of "dmesg" on Defy?
(Run dmesg command under the Linux console).
I expect to see something like:
Code:
...
OMAP3630 ES1.1
...
twl4030_usb twl4030_usb: Initialized TWL4030 USB module
usbcore: registered new interface driver usbfs
usbcore: registered new interface driver hub
usbcore: registered new device driver usb

musb_hdrc: version 6.0, musb-dma, otg (peripheral+host), debug=0
musb_hdrc: USB OTG mode controller at fa0ab000 using DMA, IRQ 92
...
I got above dmesg by Web searching for an OMAP3630 test board, not a Defy.
Just want to make sure Defy is equipped with USB OTG controller.

This function not supported in the kernel, so kernel we can not replace, because bootloader is locked.

Understood the bootloader is locked by Moto, and a kernel must be signed.
Instead of replacing kernel itself, can we just load new driver modules (*.ko via insmod command)?
Does Moto also prevent from loading customized driver modules?

Can someone help to get the outputs of "cat /proc/driver/musb_hdrc" ?
Something like:
Code:
#cat /proc/driver/musb_hdrc
Status: MHDRC, Mode=Peripheral (Power=60, DevCtl=80)
OTG state: b_idle; inactive
Options: musb-dma, otg (peripheral+host), debug=3 [eps=16]
Peripheral address: 30
Root port status: 00000000
Gadget driver: (none)

unrafa, thanks a lot for your info.
One correction to my previous command line for current USB mode:
"cat /sys/devices/platform/musb_hdrc/mode"
Following dmesg of Defy shows the internal USB modem is attached to the USB Host for modem init. But later reset as b_peripheral:

How about to use:
"echo b_host > /sys/devices/platform/musb_hdrc/mode"
to enable the Host mode again?
May run command "modinfo musb_hdrc" to get actual parameters we can use to enable the Host mode.
Something like "modprobe musb_hdrc mode_default=1".

$ cat /sys/devices/platform/musb_hdrc/mode
b_peripheral

by the way /lib/modules doesnt exist, there are 20 modules in /system/lib/modules

It would be very great if this will work.
Is there any progress?

yeah, be nice to connect 2 usb hosts so i can copy my slr pictures from a 32gb sd card over to a 320gb hdd.
I have usb y cables so i can power the hosts with an external usb charger.

Any news on this?

It will be nice to see an USB host patch/mod on Defy

hi
I've seen that some phones will enable host mode if you boot them with the data pins shorted, done with a "dongle". anyone tried this on the defy? I'll make one and try it if no one has.

hmm.. is that safe? I dont want to burn my usb port..

I doubt it will damage anything. they won't be able to source enough current.
I've checked and the omap3610 supports usb otg. I will try to test this weekend.

Scratch that, it is not the data pins, you connect the "extra" pin (pin 4) to ground.

Maybe 2nd ini make this able...

Guys, i saw something on Blog.Makezine.

Maybe this could help, would love to be able to play video files from a external HDD. Watching movies on the backseat while we drive to our vacation!

maybe we need another kernel,i think

CyanogenMod9 and AOKP for TF101G (NEW BUILD)

Working now. Check my rom

You mean you want to try if you can activate the 3G module?

I flashed it but it doesn't work. There isn't even the mobile data option. You know where you can change APNs etc.
I couldn't grab the adb output though. Adb doesn't see my TF I'll try again in the evening.

You can also put "ls /dev" in Terminal Emulator and give me the output

1. Make sure you have usb debugging enabled on the transformer (this is often not the case on new installs)
2. try the naked drivers

Many thanks for that, now I can see kernel supports it, so it should be possible to integrate 3G
I'll fix the build later

Cool looking forward to this. Maybe it stops my TF from rebooting when it's unconnected to a power source.

I'll provide it when everything is working

It doesn't work. I can't save any APNs because there is no save button.
And if I want to choose the network operator it fails at the search.
Do you need any specific logs?

Connecting Android to a serial device using USB-Serial Converter

I am attempting to connect to a serial device from a Android tablet, via
USB-Serial Converter. In order to interface with this particular serial
device, a linux library must be used as an interface.
This library takes an integer as an argument, and tries to connect to the
device at the following location : /dev/ttySx, where x is the arguement. If
2 is provided to the library, it will look for the device at /dev/ttyS2.
Very simple.
When I connect the device to Ubuntu, there's is one simple extra step for
this device to work with the USB-Serial convert. The converter is exposed
at the location /dev/ttyUSB1. I just need to create a simple soft-link with
the serial port pattern (etc "ln -s /dev/ttyUSV1 /dev/ttyS99"). It works
perfectly.
Now the problem arises for Android. The converter is seen at
/dev/bus/usb/01/01. I never seen this convention in other project. The
question is how can I direct the I/O from /dev/ttySX to /dev/bus/usb/01/01

Which android device are you using and with which kernel and android build? In my case I am using kernel 3.0.+ with CM9 on a Kindle Fire and I do see the /dev/ttyUSBx getting created along with the /dev/bus/01/01. It has been a month since I tried it but I was able to see the problem you see and here is what I remember. When you plug the serial convertor both /dev get created but since the Android USB support only uses /dev/bus/usb/01/01, the kernel in order to save power "unmounts" the unused /dev/ttyUSBx after a certain time period. You can try using dmesg to see if that is happening in your case also. There is a kernel build flag that tells the kernel not to "unmount" it but I dont remember it off-hand. Best would be to use the Android USB support to talk to your device instead of the linux library if you can.
--------Update after testing it out again and checking dmesg etc---------------------------
When I plug the FTDI cable this is what shows up in dmesg:
<6>usb 1-1: new full speed USB device number 8 using musb-hdrc
<3>usb 1-1: device v0403 p6001 is not supported
<6>ftdi_sio 1-1:1.0: FTDI USB Serial Device converter detected

<6>usb 1-1: Endpoint 2 MaxPacketSize 64
<6>usb 1-1: Setting MaxPacketSize 64
<6>usb 1-1: FTDI USB Serial Device converter now attached to ttyUSB0
At this point if I check the filesystem I see both /dev/ttyUSB0 and /dev/bus/usb/001/0xx [ xx being the current device number ]
I can work with /dev/ttyUSB0 and all is well. Now as soon as I invoke any app that uses Android USB Host Mode API to connect
to USB (for enumeration, connection or whatever) the /dev/ttyUSB0 gets disconnected with following message from dmesg:
<6>ftdi_sio ttyUSB0: FTDI USB Serial Device converter now disconnected from ttyUSB0
<6>ftdi_sio 1-1:1.0: device disconnected
At this point /dev/bus/usb/001/0xx is still alive and if I enumerate the USB devices using android API I see the same as the adaptor
name. So looks like till the Android USB API takes over the FTDI is available as /dev/ttyUSB0 but not afterwards.
------------------------Update ends--------------------------------

(a) If you see a /dev/ttyUSB1 device node created, then you can try the following in an Android terminal:
Code:
stty -F /dev/ttyUSB1 raw
cat /dev/ttyUSB1
If this shows data from your device, then you can use directly the device node to read()/write(), POSIX-style, without needing any library.
(b) If you cannot see a /dev/ttyUSB1 in your Android device, this means that you need to load the ftdi_sio kernel module (check android.serverbox.ch/?p=285 for instructions).

Let me link that for you:
"How to enable FTDI Support for your USB Host featuring Honeycomb Tablet (including sample native application)"
Also have a look at FTDI's Android Paper:
"White Paper: Connecting Peripherals to an Android Platform"
and this relevant blog, from this XDA thread.

are you using ftdi's code to modify it?

change /system/etc/permissions
this is from a question on stackoverflow titled "Android USB host and hidden devices" (sorry, i can't add external URLs yet). it worked like a charm on a micromax A120 canvas 2 phone (kitkat 4.4.2). now i can control my Arduino! i used busybox tools to do all the command line work (otherwise chmod wouldn't work). my steps (perhaps some were not required):
(0) install PDAnet drivers on my Windows 8 computer.
(1) root the phone using Vroot (now called iRoot). Very simple, only catch is that the su grant/deny page is partly in chinese, no big deal.
(2) install busybox and jackpal's Android-Terminal-Emulator available on github and the google play store (free).
(3) open a terminal window and become the superuser:
# su
(4) the file system may be read-only, so you might have to remount it:
# mount -o rw,remount -t yaffs2 /
or
# mount -o rw,remount -t rootfs /
or
# mount -o rw,remount -t rootfs rootfs /system
(5) make default.prop read/write:
chmod 666 /default.prop
(6) edit /default.prop, make the following changes:
ro.secure=0
ro.debuggable=1
persist.service.adb.enable=1
... And this is the real meat of it:
(7) To enable USB host API support you should add a file named
android.hardware.usb.host.xml and containing the following lines:
<permissions>
<feature name="android.hardware.usb.host"/>
</permissions>
into folder
/system/etc/permissions
in that folder find file named
handheld_core_hardware.xml or tablet_core_hardware.xml
and add
<feature name="android.hardware.usb.host" />
into <permissions> section.
(8) Reboot your device. Usb host api should work.

[CM9.0.0][Siyah v4.1rc1+] Prolific/FTDI Serial Terminal HowTo

[CM9.0.0][Siyah v4.1rc1+] Prolific/FTDI Serial Terminal HowTo
Hi everybody out there!
I just finally managed to use my Galaxy S2 as a serial terminal for my newly bought cubox (google for solid-run)
and as I found very little information on how to achieve that, I thought about telling the word to other folks like me.
As I am definitely not experienced with compiling kernels and stuff, I used a precompiled kernel and rom:
Siyah Kernel: Siyah-s2-v4.1rc1-CWM.zip
Cyanogenmod: cm-9.0.0-galaxys2.zip
I also installed Busybox from BusyBox Pro by Stephen (Stericson) which contains the tool microcom
Now I use Irssi Connectbot, open a session and enter the following commands:
For becoming root: su
Needed first: insmod /lib/modules/usbserial.ko
If I want the Prolific Adapter: insmod /lib/modules/pl2303.ko
If I want the FTDI Adapter: insmod /lib/modules/ftdi_sio.ko
Now I check, if the modules have been loaded: lsmod
That gives me the following:
dhd 399255 0 - Live 0xbf04e000
ftdi_sio 27902 0 - Live 0xbf044000
pl2303 11895 0 - Live 0xbf03e000
usbserial 24441 2 ftdi_sio,pl2303, Live 0xbf034000
j4fs 68207 1 - Live 0xbf00a000 (P)
Si4709_driver 24227 0 - Live 0xbf000000
ftdi_sio ... Live ... <- FTDI Module loaded
pl2303 ... Live ... <- Prolific Module loaded
Now I plug my Usb2Microusb cable into my device and my OTG Adapter and finally into my Galaxy S2
Because me OTG Adapter was a very cheap one,
I need to check if it is actually connected:
dmesg | grep usb
...
<6>[53402.191025] usb 2-1: Manufacturer: Prolific Technology Inc.
<6>[53402.237498] usb 2-1: pl2303 converter now attached to ttyUSB0
I now have a ttyUSB0 in /dev , which I can use with microcom:
microcom -s 115200 /dev/ttyUSB0
et voilà, im using a serial terminal connection to my device.
When I'm finished, I close microcom with Ctrl-x.
( I actually need to push the onscreen Ctrl in Connectbot and then press x on my touchscreen keyboard)
Now I unplug the OTG Adapter and unload the loaded modules with rmmod:
rmod pl2303
rmmod ftdi_sio
rmmod usbserial
Thats all. No more Bulky Laptops for Serial connections in cramped places!
PS: Thats my 1st post on this site and about my 10th post in forums in my lifetime.
So yeah, Im a "noob" in forumposting and a not so perfect english speaker.

U8800 not detected by pc

Hello,
I have an issue with my U8800.
It is not detected by my PC (Windows 7 x64). When I say it is not detected, I mean nothing happens. Tried all USB ports. In fact, I have tried the phone on 6 diferent PCs (4 with windows 7 x64, 1 with windows 7 x86 and one with Vista x86). The best I could get was usb not recognized (but very quickly) in one of them (x64) but not replicated. It doesn't matter if you go to Pink Screen, with battery, without battery, with sd card or without, etc. Have tried forcing all kinds of drivers, without success. Android SDK is fully installed, etc.
I also tried using 2 diferent Linux live OS's. On one of them, I was able to mount the "CD - the one with the drivers", but again, only once.
I was using Aurora with latest update when this issue started. Never partitioned. I have downgraded to Rom 136. Tried B517 and B528. I'm only able to root the device using Z4root with froyo.
Tried 3 different cables and all of them work without any issues with a Galaxy S3 and a ZTE Racer.
The funny thing is that the U8800 is detected by my car audio system (it uses windows CE 5.0) and plays media files fine. Even the USB Debugging shows up. On another car, with a "usb radio" it also works.
The device itself charges fine in every usb port i have tried
Any help would be appreciated.
Thank you

Hi guys, just an update.
I forgot to mention that the device itself does nothing while connected to the pc. No USB mount or USB Debugging icons. Just the charging message and the lightning icon.
I have tried the device on 5 more PCs and 3 more cables. Not much luck. I did get a few odd behaviours.
This is what I have found out:
Windows 7
With the phone OFF:
If I just plug in the usb cable, it will turn on and after a few seconds, the battery image will appear. While doing that, by using UsbDview, I can see USB Mass Storage Device with the idVendor=12d1, idProduct=1037.
Windows displays "Unrecognized usb device" and a pop up says that windows was unable to find/install drivers for the "unkown device" (error 45 - device is not connected).
Phone turned ON:
If I turn the phone on, no error is displayed and no attempts to install drivers are made. Nothing happens.
Ubuntu (12.0x) - Using the same method with the phone turned OFF:
Dmesg displays:
usb 5-1: new full-speed USB device number 5 using uhci_hcd
hub 5-0:1.0: unable to enumerate USB device on port 5
If I insist, by removing the usb cable, a few times, I get this:

Phone turned ON:
Only when this information is displayed, If I turn the phone on, it will connect to linux. Usb debugging will come up and I'm able to mount the SD card.
This is very weird. Can anyone help me with this issue?

Hello again,
Over 100 views and not a single idea???
One thing, when I connect the phone to Ubuntu (not in pink screen, as it doesn't work), the internal memory is seen as unallocated. Is this normal? It say 2.0GIG but no file system. I have access to the internal memory on the phone itself. Could this be a clue (The external SD card is visible and accessable).
When i type adb devices, no device is present or if I use adb shell, error: device not found.
lsusb and dmesg show the device.
Bus 006 Device 028: ID 12d1:1037 Huawei Technologies Co., Ltd. Ideos
ls -l /dev/bus/usb/006/028
crw-rw-rw-+ 1 root gabriel 189, 667 Sep 3 09:41 /dev/bus/usb/006/028
A have, at this moment, B517 installed (tried 136, 138, 518, 526, 528 with the same results).
Come on guys, I don't believe this to be a hardware issue. Please help!!!!!!!!!
P.S. I still have IMEI, serial, etc.

It is a strange behaviour. The only thing I could recommend you is dial *#*#2846579#*#* and see the usb port setting. On stock ROMs you should be able to change it to something like "normal" or "google".

Belfish, thank you for the reply. I have already tried that. Same result. Someone has suggested if the vold.fstab file has been moddified. I have never touched it so I don't know what I'm looking for. This is what's inside the file:

Is it supposed to be like that?
Thanks.

The vold.fstab shouldn't matter much. If it is wrong, then it would not let you mount sd card in android too.
I don't really know how to help you. I know there are some NV items that could alter the USB interface, but it's mostly in the kernel side. Maybe you can check your "dmesg" log on your phone. Using a Terminal Emulator, first write su for superuser and then dmesg. It gives you the kernel log messages in Android side (the phone).

Ok, I will do that. I just need to go back to 2.2 so I can root it. Once I have the Logs, I will post it. I really hope to solve this so I can try your new rom. Thank you Blefish
P.S. Is there anything I should be looking for?
