[26 MAY] USB Host mode for HD2

Update: We finally have usb host mode working on leo.
The interrupt problem i was having was fixed by liiochen, right here (his blog). He has also tested a few devices like keyboard, mouse, storage etc..
Attached is the kernel and modules in a cwm zip. usb mass storage, usb charging, usb tether and usb adb will NOT work. adb over wifi should be fine. If you were going to ask, it's based on the latest tytung kernel.
Requirements:
ICS rom
Self powered hub OR a Y USB cable
How to:
1) Reboot to recovery
2) flash file
3) reboot to android
It supports both clk/magldr.

good luck .

any news
great that some1 is working on this as its something that i want for my hd2 especially if u can.get tv out working wish ud post news on how ur getting on and more.developers would help u out i think u should do.a poll on how many people want this as id say a large percentage of hd2 owners on here would say they do. when i finally retire my hd2 would be great to turn it into a media centre by connecting it to tv and a hard drive for files. i hope u keep.at it until u get it working and if u want a beta tester count me in!!

Maybe Rick gave up on this thread, considering none of the posts in it (including this one) apart from his have been development related (we are in the development forum...)
Also, don't you think if he had news he'd post it?

I haven't given up on this but yeah, such people really do nothing but spam the thread for no reason. I will require 2.6.33 kernel at a minimum to continue because usb stack interface was changed between .32 and .33 linux. So instead of starting from scratch, i have asked tweakos who already has a .33 kernel running perfectly for the source code for me to continue, He mentioned he had some data loss but has a backup and it would take him around 4~5 days to recover and upload that somewhere.
As for the news, whatever news i would have about the host controller wouldn't be understood properly as most of it would be regarding low level stuff or unless the news is about release..
As for the possible uses of usb host would be:
1) USB joysticks, (any controller that works with linux) so you can play psx emulator with real controls, and other supporting games
2) USB TV in, Watch TV on your HD2 using a USB powered TV tuner card.
3) USB TV out, Use larger displays for your HD2 using usb monitors or some kind of usb video adapters certified for use with linux
4) USB sound cards for those who want real quality audio with an external usb sound card, but i think android does not support this. will require GNU/Linux distro.
Infact anything that works properly with USB 2.0 in linux will work in kernel space and can be used by apps which have ability for such hardware.

Wow, that's great. I love USB TV out function.

I want it, good luck

Good luck with this one. It would be great to have on our beloved hd2's

How about using my kernel 2.6.35.14 forked from ACA which is forked from Marc? I have done a lot of work making it very stable and fast...

Rick_1995 said:
. There are posts which confirm that OTG worked in froyo sense, so i will be testing the support in froyo roms and gnu/linux builds like ubuntu for further research.

Which froyo roms have OTG support?
It would be useful to use one for Ubuntu http://forum.xda-developers.com/showthread.php?t=1025499 (and possibly Debian http://forum.xda-developers.com/showthread.php?t=1029390) via VNC
Thanks

Dunno if they would work, btw with my kernel i have usb root showing up but cannot yet test anything because my usb hub seems to be broken and i don't have any usb female port lying around.

OP updated.

Hi sry slightly of topic....is there a new version of magldr in the works? What is the expected time of release?
Many thanks

USB HOST development

I found some posts around but nothing terminal. Is it possible at all A100's USB to behave as host? I mean is it possible to be developed, I know it is not a standard feature.
I will be glad to donate to a ROM which introduces this feature, as well as many others, I think.
Thank you

I'm not sure. The kernel source usb driver does seem to have OTG, but I have not tried it. I'm may not be enabled for some reason.

Look in this Service manual scheme on page #23. It will answer to your question.
In general the ansewer is no.

Acer A100 Support USB with ADK.
more info about Android ADK
http://androidcontrol.blogspot.com/2012/05/beginning-android-adk-with-arduino.html

I realize this thread is a bit old and didn't really go anywhere, but if you check dmesg, you can see that the A100 uses USB 2.0 internally for its own devices. (E.g. pl2303, UVC, etc.) So that might mean if you can find the right points, you could theoretically tap into a USB 2.0 bus. No idea how useful that might be.

anyone can check this?

The dock port? No it doesn't support usb at all I don't think. I think it's like charging and hdmi and audio, maybe one of the few with one can verify that.

Does the dock even have hdmi out? I was just looking in to it, only $30 on eBay btw , anyway I don't see an hdmi out in any pictures and I read about USB in a description somewhere. Does anyone have one to inform us?

It has HDMI and audio out:
http://www.acer.co.uk/ac/en/GB/content/model-datasheet/LC.DCK0A.002

http://android.sztupy.hu/usbhub.html
It should be possible:
I might also try to create kernels for other devices if the following are true:
The kernel source is avialable on github. It is either a kernel for gingerbread (>=2.6.35) or for ICS (>=3.0)
It contains (or has links to) the initramfs and all the other files needed to create an update.
If creating the update is not straightforward I also need a script to do this for me
After the update is made I need someone with the device to test it for me. If the feedback is positive I'll build versions for that device too, whenever something is changed.

A kernel can't allow functionality that isn't in the hardware, USB host is active in the kernel already, there's just no hardware support for it on the a100.

I'm on ezT20 kernel and USB Host Diagnostics is saying "kernel claims support: no"
Which type of USB controller HW has the A100? I want to read the specification sheets if available.

Everything is there to do it, just not hooked up. It's been discussed over and over again. It's enabled in the linux society kernel, it's based on the ezt20 kernel but had quite a bit more done to it, I probably should have said which kernel. Well I never verified it, he just said it was enabled at the kernel so it was something else stopping usb host. The CM9 kernel may also have it as it was shared with the a500 which did have usb host, just a different defconfig used.
If you want to read those sheets then dig through the forum for them, there was a post for it a long while back, or even Google for a minute will find you the specs and manual for it which includes all the hardware used. It won't help as the parts listing will give device information that says it should have usb host, but it doesn't, it's not connected for some reason.

Hdmi mirroring enabled on Samsung Desktop Dock (the portrait one)

Hi guys,
if you've bought a samsung desktop dock for yout GNES, I've compiled a pure stock jelly bean kernel with the hdmi mirroring mode enabled for official samsung desktop dock.
If you want to test it, here is the thread and download link:
http://forum.xda-developers.com/showthread.php?t=1780481
WZ

I wondered about this. When I got my GNex it had ICS and I had one of the MHL adapters from my Samsung Infuse (I think that's what it's called) and it worked flawlessly. I haven't tried this with JB yet but I wonder if this type of tweak will be needed or if it will just work. Thank you for this solution btw.

With android 4.0.4 or newer, the samsung desktop dock is recognize in a different way to mhl adapter.
The dock haven't hdmi mirroring functionality out of the box, while the mhl adapter still have it.
So, to use the hdmi mirroring with the dock, just like an adapter, is necessary thi kernel fix.

Is there any kernel out there that has this tweak allready in it, like franco kernel or lean kernel?
I cant find any information about this. Unfortunally im not allowed to post anything to the developers section.
Or is there anybody who could apply this tweak to the newest franco kernel (which im using at the moment)? Because the Kernel you posted here is the stock one without any functions and its pretty old now, right?
And what is the amount of time needed to apply this tweak to a kernel for someone who has kernel-compiling-environment? Im just wondering if this is much work?

[Q] USB On-the-Go for Xperia PLAY

I read threads here at XDA and Xperia Blog regarding this feature. It appears we need a specific app and root access to make it work. But I thought USB-OTG feature on the Xperia PLAY was native?
It was stated on the Xperia PLAY's specs sheet at GSMARENA even before the app I mentioned earlier became existent, IMO. I also previously thought that all Xperia phones after X10's family support this feature natively.
Can anyone clear this up please?
I already have a SanDisk Switch 16GB and I'm planning to buy a USB-OTG cable for this reason. Please help.
Thanks in advance!

Does USB OTG work with this app on the Xperia Play if you are rooted? Is it possible to get it to work at all?
I would LOVE to have USB OTG but I don't want to buy a cable and not be able to do anything with it...

anyone?

Hello? Anyone?
I thought this was a help-to-get-help forum...

ics does not see usb

Hey everyone
I have the sprint galaxy s2 , stock ics rom (rooted)
this unit does not see the usb, (no otg), there is no window telling me a usb device is hooked up, the thumb drive does not power, and the usb host diagnostics says my device does not support usb
I installed stick mount just to be sure and there is no device seen
anyone have any ideas how to enable this, am I missing a file somehow, or possibly a link to a stable ics that does support otg
any help is appreciated and thanks in advance

Right now from the looks of it, self powered OTG is nonexistent on the epic touch. There might be a chance that OTG through a powered hub or USB Y cable might be possible. But standalone? Not a chance.

thanks for the response but my galaxy doesn't see powered usb devices either...I think I am missing a file or need to enable something as others have what I am looking for
ps, this youtube looks like e has usb otg self powered
http://www.youtube.com/watch?v=giJXF5pIITc
according to the posts on that tube, some users can do it some can't, it looks like sprint cannot...something is missing in their rom I suppose

I am now led to believe it's more likely a hardware issue rather then kernel, I think if it were a kernel problem simply flashing to a kernel that worked would do the trick and porting it over would simply be the same thing as porting say a verizon ics over to sprint
nobody can get otg working on a sprint epic touch regardless of kernel.
so sad, I traded up from 3d otg for my torque program, now I see if I kept my 3d and installed ics I'd be gold
