Any rom with working usb host mode?

Hi, I am trying to find a Rom that has a working implementation of USB host mode / USB otg.
Haven't found much info yet, just some info about the needed kernel modules/patches and some scripts. I would really want to know if someone has used a rom on the desire that enables you to easily connect USB storage/card reader and access data on it.
Very interested in your experiences in this matter!
I'm on sebs aio now, will try sandvolds ics rom and see what's in it this weekend.
But i´m guessing that "USB mass storage" thats listed as a feature in that rom is just the possibility to connect the phone to PC and access it as a usb storage device.

Just found an app that might be helpful if the only solution is a rom running the kernel patches.
[APP][2.1+][ROOT] Usb Host Controller 0.42
http://forum.xda-developers.com/showthread.php?t=1468531

238 views and only replies from myself....hmmm
Guessing that this is not a very wanted feature from the lack of responses, but now I have it up and running, so here is a short guide how to make it work:
Pre-requisites:
HTC Desire with suitable recovery ([TOUCHCOVERY] 4EXT Recovery Touch v1.0.0.3 RC 3 | USB unbrick with autodetection, worked like a charm)
USB Hub with power supply
USB OTG cable
Some USB storage device (USB-stick, USB hdd...)
1. Install (via recovery)

ROM with USB HOST mode capabilities
2. Install (via recovery)
http://tim.mactory.com/htc-desire/
CM7 USB HOST patched kernel
http://tim.mactory.com/HTC_Desire/2.6.37_host_mod.zip
3. Install Usb Host Controller 0.42 App
[APP][2.1+][ROOT] Usb Host Controller 0.42
http://forum.xda-developers.com/showthread.php?t=1468531
4. Load kernel modules
* Open terminal emulator on phone
* Type "su" [enter]
Paste following into terminal window:
insmod /system/lib/modules/$(uname -r)/kernel/drivers/usb/core/usbcore.ko
insmod /system/lib/modules/$(uname -r)/kernel/drivers/usb/host/ehci-hcd.ko
insmod /system/lib/modules/$(uname -r)/kernel/drivers/scsi/scsi_wait_scan.ko
insmod /system/lib/modules/$(uname -r)/kernel/drivers/scsi/scsi_mod.ko
insmod /system/lib/modules/$(uname -r)/kernel/drivers/scsi/sd_mod.ko
insmod /system/lib/modules/$(uname -r)/kernel/drivers/usb/storage/usb-storage.ko
5. Run Usb Host Controller 0.42 App
Go to Settings tab, check/edit mount points ("mnt/sdcard/ehdd" equals a folder called "ehdd" on the Desire SD-card)
Go to USB tab and find the device you want to mount
Click mount and select mount point
6. Use your favourite file manager to access the files on your devices, for example ES File Explorer
7. Thank the devs that made the coding for all the above!
Brilliant, now I can use my phone to transfer photos from camera SD-cards to a USB HDD while travelling.
Have fun!
And a big thanks to the devs!

hi there, have u try this on sebastian Runnymede AIO rom?? it will be great if it is compatible with usb host mode..

Just noticed a sense usb host kernel, will try it with sebs latest today.

mind telling me if it works after u test it?...cause i don't have the cable usb otg cable right now, if it is working with sebs rom i will get one for sure, thanks

Sebs AIO tested
Hi,
Tried Sebs AIO 6.01 with the kernel thats in it and with bravo-2.6.35.8-snq-111118.zip (snq_kernel_with_usb_support)
No luck with any of them.
Could not load the kernel modules, tried copying them to the device but I couldnt manage to load them.
The Usb Host Controller 0.42 App did not report any devices or usb host functionality.
I'm guessing that the kernel modules needed isnt packed in the kernel.
Cant find the files where they where when i tried the Supreme with CM7 USB HOST patched kernel and the setup looks a bit different.
Guessing the .ko-files needs to be packed into zimage or something i'm a noob at this.
I´m having trouble finding info about this, maybe the info is there but i'm to lost to figure out what i'm reading.
I would love to be able to have the usb host functionality in Sebs AIO, its the best rom I've tried!
So if anyone got some info on how to get usb host mode working on a sense rom i'm still very interested!
Any 2.6.35 sense kernel that we can load up the .ko files on?

Up ..Same .. I need know how to use this USB HOST

Well, if you read post 3 above you find step by step instructions. Msg me if you need more info. Works ok with cm7 roms like mildwild also.

have you test it before asking this question?
as far as i know, since jelly bean the otg is already supported out of box for our hox
external hdd i am not sure but usb flashdisk drive i am sure you can connect it to the phone

Thanks for your response , i know that i can run usb sticks but to run a mouse or controllers i need :
-an OTG cable
-a USB Y-cable
-a usb perhipheral (eg: mouse, keyboard, thumb drive, etc)
i need a kernel for self powered OTG which means that i don't need USB Y-cable !!!!!!!

i think what you need is kernel that could provide enough power for that
stock kernel has usb otg support but it doesn't provide enough power for your usage
but to connect mouse , keyboard, and thumb drive in the same time is quite much don't you think ? :silly:
hoping you could find the solution for that
how about trying trip's kernel ? or kholk's kernel ?
but only support android before 4.2.2
these 2 kernels have the otg support even before htc gave supportto otg officialy
maybe the parameter is quite different so the supplied power may be greater than the one now
just my opinion

There is no kernel that can do that, it is hardware related...imposible to do that without Y-cable

[Q] I deleted my OS while trying to install thunderrom! how can I fix this?

The title says it all.
I'm currently in TWRP mode but can not reboot because no operating system.
My tab s 10.5 is currently connected to my PC so at the very least it will not shut down (100% battery).
How can i fix this? I have the thunderrom v2 zip file on my PC but no way to transfer it.
thank you

Either ADB side load the rom, or put it on a USB stick and use a OTG adaptor.

Yes, I pressed Storage and got the select storage: menu but the USB-OTG (0mb) option is not available.
Im trying a different USB stick.
Would the file system matter? Its NTFS.
Im currently in TWRP; If i click reboot > recovery would it boot me into TWRP ? im scared of bricking a deviced I saved up money for

It's pretty hard to brick a device. I never have. Format a stick fat32 or exfat to see if that works.

Oh man, thanks a lot. I tried to install the rom with another usb stick with fat file system and it worked.

Awesome!

can you use odin to to flash the firmware ?

it cannot read NTFS... save bet will be 32bit. dont know about exfat

use otg without y cable!

I have found a way to use otg in s3 neo plus without the need of y cable or external power source. Otg device will get power from your s3! First plug in your otg cable (use normal otg cable not y cable) don't connect anything in the other side of otg cable for now. The go to terminal and execute this commant in super user mod.
echo "1" >> /sys/kernel/debug/regulator/8226_smbbp_otg/enable
you will hear a sound. Wait 2 second.now connect your usb device to otg cable. And you otg device will get power from phone. And when you are done using otg execute this code in super user mod
echo "0" >> /sys/kernel/debug/regulator/8226_smbbp_otg/enable
Don't forget to execute this code or your phone will not charge while connected to charger.
And i used otg using stock kernel.
If you face any problem or this doesn't work reply me i will try to help.
And if it works then reply and let others know.

Finally now I can use my OTG cable! ^_^

not working on stock rom
tried on s3 neo dual sim

yep it did worked, i just tested in my sgs neo + GT-I9301I running PHN latest Stock Firmware.
Thanks a lot for all the work and effort coz it's an awesome things that we'll be able to do that without external power.
the only thing is that, it's only ES FILE EXPLORER that can manage to find and give me access to my flash drive ... but the stock file manager, mixplorer, root explorer, don't detect the device at all !!!! so i was wondering if there is something special i should do.
otherwise for other non storage devices (mouse, keyboard, game-pad) get detected automatically

When you connect the flash drive you will get prompt for allowing es file explorer to use usb device. Don't click ok,click cancel. And if you have ticked use by default then goto es file manager app info and click clear default. Your usb device will be mounted by system (same as external sdcard ) you can check it in settings - general -storage. And one more thing if you flash drive is formatted in ntfs it will can only mounted by es file manager. System can only mount file system like vfat exfat fat32 etc. As far as i know.

Not working on my device at all. No sound nothing. And my phone is charging even without disabling. What's wrong
Using the stock 4.4.4 rom

maybe I'm wrong but I think it's ur stock rom
to my knowledge there is no 4.4.4 ROM for the GT-I9301I, up to date stock ROM so far is only the 4.4.2 ! so I'm a bit curious

I tested with usb flash drive,external hard drive,zaza remote,mouse,keyboard and joystick and it is working good.

Clone this wiki locally
https://github.com/452/USBHIDTerminal.wiki.git
How to enable USB host API support
Some Android devices have no support USB On The Go (OTG)
USB host mode is supported in Android 3.1 and higher
Also for this you need ROOT access.
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.
Reboot your device. USB host API should work.
Procedure:
adb pull /system/etc/permissions/tablet_core_hardware.xml
Update that file and create android.hardware.usb.host.xml as specified by Greg-q.
adb push android.hardware.usb.host.xml /system/etc/permissions
adb push tablet_core_hardware.xml /system/etc/permissions
Reboot.

I tried this all in my samsung e700h but not suceeded. If anybody suceeded in doing this way plse tell how???

You can try using NeOTG in grand 2/s3 neo forums. If you have a kernel support of OTG,then it'll work

How to check if my kernel supports native USB OTG support? Perhaps I have to check for it in "/dev/" or somewhere?

doesnt work on e500h with stock lollipop

Someone have the github files that were taken down?
Sent from my SM-A520W using XDA Labs

No OTG in E700H it seems...
The USB controller used in Galaxy E700H is Richtek RT-5033 which is apparent by examination of
PHP:
dmesg | grep 5033
This RT-5033 handles battery management and flash LED etc. but the driver for this in kernel given by Samsung doesn't have anything specific related to USB host/OTG.
There is a mention of a register for USB OTG/Host, but it's not documented.
So even if the chip RT-5033 supports OTG, without the support in kernel, OTG can't be enabled.

I want to enable OTG support on my Irulu X11 tablet, I can access a recovery menu and there's a lot of options in there. I can update from multiple source, I can reboot to bootloader... etc...
I don't have any knowledge in this 'domain' but I'm pretty good with that stuff usually.
If you can explain to me how I can edit those files to enable the USB OTG to work, I would bless you.
Basically, someone said that in the Recovery Menu your tablet is practically 'rooted', I'm not sure what that means and I hope someone can help me.
I got the file ' android.hardware.usb.host.xml ' and it's already got the permission in there but it's not in ' tablet_core_hardware.xml ' and when I try to edit it for File Explorer, I get an error when saving.

Actually, I think OTG support is already enabled.
If I can use a micro USB keyboard for my tablet, that means the OTG support is working right?
Then, my problem would be that all the apps I'm trying to use are not made my version of Android or something.
Let me explain.
I bought a USB microscope and I want to connect it to my tablet to I can inspect stuffs on the fly.
It's working perfectly fine on my computer, but I've tested 10 apps on my tablet and none are showing the camera view but they detect something in USB (USB Camera) and the leds on the lens are turning on.
What's the issue ?

Well, apparently my device doesn't have any built-in UVC support and that's why I cannot see the video of the camera.
Is it possible to add UVC support? I know at this point I should make my own thread but let's see..

I don't understand so much of this .. i tried too many videos to make the E7 compatible to otg and it worked but when i try to use the otg experimentally it doesn't work !!

Ok I've gotten to the end of the instructions, the last step, & I have an issue...
When I enter:
adb push android.hardwae.usb.host.xml/system/etc/permissions
I get:
adb.exe: push required an argument
I entered the command exactly as written so what is the problem & how can I fix it?
Thanks. .
