CDC ACM device (ttyACM0) has no output - Galaxy S 5 Q&A, Help & Troubleshooting

I use a device that is connected to Galaxy phones via USB using CDC ACM driver. Since Galaxy S3 (I9300) and Galaxy S5 (G900H) doesn't have that driver in the default kernel, I built my own kernel/modules and flash the kernel or using insmod for the modules. I Also use Galaxy S8 (G950F), but the default kernel there has those drivers because of samsung's new gadgets.
Without the drivers there is no /dev/ttyACM0 file when connecting the USB device.
In I9300 and G950F the file appears and when using 'cat /dev/ttyACM0' I receive the regular output from the device as expected - everything works perfect!
However, with G900H I can see the file but there is no output at all (I checked the permissions and its rwx for all and I also have root permissions).
How do I get the USB device's output with G900H? I have the device file but its useless..
Thanks!

I'm replying to this old post in the hope that you still have the i9300 kernel (or advice on how to make the modifications). I'm so close to finishing a cool little project and the usb serial driver is the last piece of the puzzle!

ADVICE/SUPPORT : UVC Camera on Samsung Galaxy Tab 10.1- No device Node??

HI,
I am trying to interface the UVC Camera to the Samsung Galaxy Tab 10.1(GT-7510) , but I am not able to see the device node getting created in the shell( I have installed the Linux terminal Shell Application) and rooted the device using this Video .Can somebody plz tell/advice how I can achieve it and access the device Node or at-least get it created.
Following is the log on dmesg :
usb 1-1 new high speed USB device using tegra-ehci and address 97
hub 1-0:1.0 unable to enumerate USB device on port 1 ,
usb 1-1:device v0ac8 p3420 is not supported
On My Laptop I get this output on Dmesg :
[12307.364237] uvcvideo: Found UVC 1.00 device Venus USB2.0 Camera (0ac8:3420)
[12307.366108] input: Venus USB2.0 Camera as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.1/2-1.1:1.0/input/input14
[12308.537059] usbcore: registered new interface driver snd-usb-audio
also i can see the camera getting blinked on connection which proves that it is getting the power-supply and getting connected with the system.
I think there is a support for UVC USB devices in the kernel (not sure) otherwise I am ready with the Kernel For Samsung Tab 10.1 (GT-7500 (Higher Version: GT-7510)) from here .(GT-P7500_MEA_Opensource.zip (requires Login).
Plz assist.
Rgds,

You seem to know a bit about what you're doing. I'm not really familiar with this device. I did a search and did not find anyone who has don't this yet. The first priority is to get a Linux device in /dev/ folder. This is generally handled by a device driver and a udev rule. Try the newer kernel if you can. The android 4.0 ics has a Linux 3.x kernel. See if switching to ics helps. Try compiling a custom kernel with all modules. Once you have a device, try using SSH or sftp from your desktop under Linux to stream from that device with vlc or another media player.
Do you have any examples of this device in use on mobile Linux? It may require writing an entire kernel driver.
HI,
Yes that is the same line of thinking for us as well.We are trying to compile the kernel and load it .- Ongoing
I believe only the zImage is the one which is to be flashed.But I am little scared to do this.Couldn't find the instructions to loading the Zimage even though I can compile one.

Flash it with Heimdall, even if it won't work you will be still able to get into download mode of bootloader (which you aren't supposed to flash) and reflash the kernel with stock one.

[Q] Galaxy S4 USB OTG Ethernet?

Hi all,
Can anyone with a USB to Ethernet adapter please test if this works with the Galaxy S4 using an OTG USB cable? I have read it works with the Nexus 7 but would love to know if it works with the Galaxy S4. Would be quite handy to hook up the galaxy directly to my 100mb internet.
Thank you.
S4 tested with two USB Ethernet modules. unsuccessfully

I tried with some generic USB - 10/100 Ethernet (its working with Android 4.0.1 in Point of View TV Stick) and Delock Gigabit USB (not testetd with Android previously) but not working with S4. I check OTG cable connecting USB flash drive and it works with S4, same with USB mouse and USB keyboard. This Ethernet 10/100 USB module after connecting to S4 lights up so its powered but S4 does not looks like recognize it. i have to small knowledge or S4 hasn.t some drivers.

Thanks for trying! A few people have tried with no luck unfortunately. Hopefully someone can create a loadable module that contains ethernet drivers for the S4!
Cheers

S4 connected via OTG to extrenally powered USB HUB. Ethernet USB adapter connected to Hub. Nothing happens on S4.
To verify connect USB Flash drive to USB hub and its sucessfully detected and browsed on S4 (so hub itself working).
Tested USB Ethernets:
USB Ethernet 10/100 "JP1081B"
USB Ethernet 10/100/1000 "Delock 61730"

I thought that would likely be the result, but always worth checking non-working USB OTG stuff with a powered hub.
I have a couple of different ethernet adapters, driverless ones that are confirmed working with the few Android devices (tablets) that have been reported to work with ethernet connections, will post results when I get them (I expect them not to work).

Fingers crossed but I have my doubts too unfortunately.
Any updates to this interesting thread?
I too would like to get this going with my new Samsung S4, mine is via Sprint, if that matters.
I have tried to OTG cable w/ a USB and StickMount Pro, that works.
BTW, my S4 is rooted via the CF Auto Root method.
has anyone actually found a driver for this?
Possible???
Is this in any way possible?? I am planning to buy one adapter for my s4. Is it worth buying??
I would be interested. The device recognizes it but does not work with this program Ethernet Google Play.
Forgive my language I'm using Google Translator Spanish to English.
I saw a post to introduce myself.
Thank you
Thank you All. Following is how I got LAN Ethernet to work on my Galaxy S4. Some of these steps are very risky and may wipe out all your phone data or make your phone unusable. So I am not recommending you to try it. I am only sharing what I did in my phone to make it work with OTG Ethernet. Also the procedures are very device and version specific. Even same model phones with different Build version and Android version may give different results.
My Devices:
Samsung Galaxy S4 Model Number: SGH-I337M
Android version: 5.0.1 (Lollipop) SDK 21
CPU Architecture: ARMv7
Build Fingerprint: jfltevl/jfltecan
BobJGear OTG Ethernet
ASIX AX88772A Chipset
Following is the Summary of the key steps and troubleshooting. You can search online to find the APKs and Installers or to know more details.
Install Droid Info App to get details of the phone CPU
Install Kingo ROOT App on the Phone and Root the Galaxy S4
Install Odin3 v3.13.1 on Windows 10 PC
Use Odin3 to install “Team Win Recovery Project” (TWRP) on the phone. TWRP was necessary to install XPOSED Framework. The specific version of TWRK that I could install is TWRP 3.1.1.0. I installed it using the file with following file name:
“twrp-3.1.1-0-jfltecan.img.tar”.
The other newer version of TWRP did not work. It kept going back to default recovery menu. Also uncheck “Auto Reboot” in the Odin Options and manually reboot phone to Recovery mode after installing TWRP from Odin.
If you get following message when trying to start TWRP in Recovery mode, Just wait few minutes and TWRP will start.
RECOVERY IS NOT SEANDROID ENFORING
SET WARRANT BIT RECOVERY
During TWRP initial setup Swipe to “allow modification” to System partition
Install XPOSED Installer using apk with following file name. This is an App used to install XPOSED Framework.
"Xposed-Installer-3.0-Alpha-4-2016.10.16.apk"
After installing it, it showed warning that it is not compatible with my phone and android version. Leave the XPOSED Installer installed. Use alternate method to install XPOSED Framework using TWRP.
Install XPOSED Framework using TWRP. I installed the XPOSED Framework version 87.1. That is the only version that worked. I used zip file with following file name
“xposed-v87.1-samsung-5.0.x-sdk21-by-dkcldark-arm.zip”
The other versions of XPOSED Framework was giving following errors.
The installed firmware is not deodexed!
This version of Xposed requires deodexed firmware!
After installing XPOSED Framework, open XPOSED Installer and install Hack Connectivity Service
Install Terminal Emulator.
Sometimes after reboot, the Terminal Emulator shows blank screen. Wait for a minute or so and it should show the usual prompt where you can enter the commands.
Install SuperSU Free v2.79
I installed Ethernet Droid apk, but it did not work.
I installed Busybox but it was not necessary to be used
Usual Steps
Once everything is installed, following are the usual steps to connect to Ethernet.
Connect the Ethernet OTG to Smartphone.
Disable Wifi
Enable Wifi Hack in “Hack Connectivity Service”
Start Terminal Emulator and run following commands. This needs to be done every time we switch from Wifi to Ethernet.
Code:
su
netcfg eth0 dhcp
ip rule add from all lookup main pref 99
ndc resolver setnetdns eth0 "" 8.8.8.8 8.8.4.4
exit
If I don't use the above "ip rule" command, I can only ping to router using Superuser and Internet does not work.
Also previously it was not recognizing website names while pinging. the "ndc resolver" command resolved that issue.
Once above commands are executed, I can use LAN Internet on my Galaxy S4.
Update on Nov 19, 2019:
For the Usual Steps, the Terminal Emulator Commands after "su" line can be saved in a file in the local storage of the phone with name such as "lan.sh" then following commands can be used to execute the file.
su
cd sdcard
sh lan.sh
Video Demonstration
The demonstration of my final results is in my following video. It also has an example of Simultaneous Charging while using OTG Adapter.

[Q] RT2800 USB vs Monitor Mode

Hi,
I have just picked up a Note 3 on Three UK.
Am I right in assuming that the wireless chipset BCM4339 which is the same as on the Nexus 5 is still not able to use bcmon mode to allow us to enable monitor mode?
Would a specific ROM be necessary to allow a TP-Link WN722n (RT2800usb) to work on OTG cable?
I have tried both bcmon on my note 3 and also my TP-Link via USB OTG cable and neither have had any results.
Thanks
Toby
I've installed USB Host Check to confirm that USB host support is enabled on my note 3.
(android.hardware.usb.host.xml OK)
(handheld_core_hardware.xml OK)
I then installed USB Host Controller.
Both devices recognised but obviously not working. (Atheros USB 2.0 WLAN for TP-WN772n) and (ASIX Elec Corp AX88x72A) for USB ethernet.
When I run USB Host Controller I get the following error message:
"s3c usb host driver not found".
Another member on XDA posted a link to the Halaszk Kernel on the N9000 apparantly having OTG USB host support for S3C

I'm still hitting a brick wall on this one search wise.
Would stil love to be able to use my WN722N on my Note 3.
Has anyone any experience in modifying the Kernel Module to allow the ath9k to work on Note 3?
Getting a wireless adapter to work on Ubuntu or any form of Linux can be difficult if the manufacturer doesn't provide direct driver support or at the very least a "Tar" which would allow an end user (with sufficient skill) to compile the drivers them self. My understanding of this is limited but from what I can remember Android is JavaScript VM running on a Linux kernel. So you need the Linux source code for the driver which usually comes in a "Tar". Feel free to correct me if I am wrong.

[Q] Missing CDC drivers

I'm trying to install Samsung mobile phone drivers but no matter what I do I miss these drivers when I connect my Samsung Galaxy Y:
CDC Abstract Control Model (ACM)
CDC ACM Data
CDC OBEX Data
CDC Object Exchange (OBEX)
I have googled for solution and I have followed recommended actions (install Kies, install latest drivers, reinstall all, use "have disk" method) on different operating systems (Windows XP, Windows 7) but I got no success.
My phone doesn't boot (I need to flash it with Odin) so I have tried it all in recovery or download mode but I understand it should not really matter as it's Windows issue, not a phone. I'm using original Samsung USB cable.
Could somebody with a working setup could check if they have above devices correctly installed and provide me more information on the driver file? I mean the information from driver details tab in Windows, ie. name of *.SYS file, *.INF file so I could at least check if I have a driver on a disk.
Any other suggestions also welcomed!
Kies is useless & is not required for galaxy y gt-s5360 as it's not supported for firmware flashing on this device so uninstall it
Uninstall any Samsung drivers you have installed from add/remove programmes
Goto my firmware thread at top of Dev section or link in signature
Download & install USB drivers on my thread
Download the firmware from my thread depending on region
Follow the instructions fully
You can manually install drivers if you wish by clicking on unknown device/device with yellow! click have disk & navigate to where you installed Samsung drivers eg c:/programme files/Samsung
It has finally worked (Windows XP)! I have just installed drivers and followed your instructions (with download mode, not recovery mode). Initially I had other unrecognized devices (very generic usb ones) but after a few attempts (usb plug out, usb plug in) the phone has been detected successfully and I managed to flash it. Many thanks!
Sorry, I forgot to mention. I had also removed a battery.
I have the same issue, Could you please paste the links for downloading the drivers.

Galaxy Note 4 (SM-N910T) w/ LineagOS 15.1/NetHunter - Alfa AWUS036NEH not detected

First time posting, but I've read through dozens of threads and have used the site extensively. I cannot seem to find an answer to the issue I'm having. I had an old Galaxy Note 4 lying around and wanted to see if I could install NetHunter. After tons of trial and error, I was successful in flashing LineageOS 15.1, addonsu -15.1 arm, nethunter-generic-armhf-kalifs-full-rolling-2017.10-20171013-0449, and kernel-nethunter-generic-armhf-3.15.4-20170211-0304 (too new to post link of the NH builds). I have full chroot, updated busybox (v1.25-0-NetHunter) and SuperuserSU to manage root privileges. I had to install all of the tools (e.g., cspolit, DriveDroid, OpenVPN, etc.) individually, but they seem to be in working order.
My issue: I bought an external wifi adapter (Alfa AWUS036NEH) with a chipset (Ralink Technology Wifi Adapter RT2780) that supports monitor mode. The Wifi card appears to work flawlessly on my macbook with Kali distro, but I can't seem to find a way for the NH kernel on the Note 4 to recognize the adapter. In the kernel I flashed, I can see the rt2870.bin firmware required in the /system/etc/firmware folder, but for some reason Nethunter does not recognize the adapter. On most Nexus/NH builds, the wifi adapter is found to be compatible and is usually plug and play.
When I run:
-Kali terminal
-ifconfig
There is no wlan1. Only wlan0.
Same thing if I run iwconfig.
When I run:
-kali terminal
-airmon-ng
I receive a prompt that states:
Found phy0 with no interface assigned, would you like to assign one to it [y/n]?
-y
ERROR adding monitor mode interface: command failed: Operation not supported (-95)
No surprise, the above is indicating the embedded chipset does not support a monitor mode interface, but it doesn't even list the external adapter.
when I run: lsusb
Output shows the Ralink wifi adapter on bus 3:2.
I understand NetHunter was not built for LineageOS 15.1, but there has to be some way to maybe push the firmware or modify the firmware (I have the original firmware from the manufacture) to be compatible with my current build? Do I need to compile my own Kernel for this to work properly? Why doesn't the generic NH kernel, with the rt2870.bin file work?
Thanks ahead of time.
Have you tried using Magisk and flashing the Kali Nethunter module with that? It also includes multiple wireless firmware and I believe the correct one for your Alfa dongle. I too just bought that exact WIFI dongle and I'm still in the process of setting up Kali on my Note 4.
I had a similar issue as you on my OnePlus 5T even with the Magisk module for Nethunter. I'm going to try and find a different kernel because I think that's my issue on that phone.
My Note 4 is N910P but I'll let you know if I find something that works and maybe it'll help you find a way on your variant.
