[Kernel][Both] USB host mode support added (github link)

Hi ya'll,
I've just added USB host mode support for the Galaxy Tabs. ( Can some mod move this post to the Android developer forum and bless me for posting in that forum? I'm happy to answer questions/discuss but I can't post there yet because I just created this account)
[Ugh! because I have less than eight posts I can't include github links - you'll need to linkify yourself... ]
The github site is here:
github.../humcycles/galaxy-tab-modified
Documentation on the changes:
github.../humcycles/galaxy-tab-modified/blob/master/Kernel/Documentation/usb/s3c-otg-host.txt
The changelist you probably want if you are want to cherry-pick into another kernel tree:
github.../humcycles/galaxy-tab-modified/commit/99388abf98f8b8583dcfb31339c8673a9fea62bd
These changes fix a number of bugs in the Samsung host mode software but are probably not well suited for regular end users. I would recommend that developers who are generating Galaxy Tab kernels consider picking up these changes.

Does P1000 have the right hw, can it provide 5 volts to usb client or we also need a power injector (usb hub)?

It really works? That would be superb news! Thank you very much for investing your time in it. Can`t wait to see it in a kernel on my tab.

Yes. It works for me on a Sprint SPH-P100, but I bet it will work on all 7" tabs (the USB hw seems the same). I look forward to some other dev trying it out and letting me know how it works for them. From looking at the samsung sample code, I bet it will work on most samsung chipset based devices (certainly the S5PC100 based ones).

I bet it will also need power for the 5V USB. In the samsung code they have bits that look like it is turning on the right LDO to have power, but nothing comes out on my SPH-P100. Either the sw init needs more work, or they didn't stuff some part when they built up the units.

Does that mean this hasn't actually been tested on a SGT yet?

I've tested it on a few Sprint 7" SGT's here, but it would be great for another dev to try it in their kernel.

It is a great thing, you deserve so many thanks!...
Now what I need is a kernel with usb host and swap enabled.

Can somebody explain why it is needed? What is it good for?

It allows the Tab to act as the controller for USB devices, rather than the other way around. In practice, it means that you can use things like usb sticks, keyboards, mice and the like which usually require a computer (the host) with the Tab.
Anyone more knowledgeable, feel free to correct me.

Hmm - I just want to be able to discuss this in the right forum. I hope I don't get banned, but I don't really care to much - I made these fixes because I needed host mode for my application. I'm almost there - just need one more post

[Bounty] Acer a100 USB Host/Mass Storage

My pre-apologizes if this is the wrong forum to post this in.
I'm calling it. It's Bounty time. I want to hook up a large external usb drive to my a100, and after reading countless posts of it being a kernel level job, and things I admiralty know nothing about, I'm ready to pony up $20 for the cause. Anyone else? I'm most certainly tired of waiting, and I am sure money is a decent motivator.
Thanks.

Why not just use the USB drive as a network drive and use ES File explorer to mount it?

I build it in FLEX-A100-REAPER-RF1 (not yet released), but it is in testing stage and as I don't have a a100 I cannot test that feature. You can also always use drivemount.

We don't have kernel sources, and Russian support told me that they are not planning to release them. And without sources any money won't help to do USB Host... Also, in service manual on schemes you can see that USB Host is not available because of hardware problems...

That's exactly what I thought - that the hardware itself didn't support it
I thought that they had to legally release kernel sources as the Linux Kernel is under the GPL license? I'll do more research and hound them down for sure.

Yes, they do have to release it. HP had some problems with the Touchpads some time ago because of this.

[Q] USB OTG Problems

just got a chance to try out a USB OTG cable. my current setup well not allow me to explore files on my flash drive. I know the flash drive and cable is good because I plugged the same setup into a friend's SGS3 and it worked right away.
the question is, is this more likely a problem with my kernel or my ROM?

Maybe both. Vague problem, vague answer.

ok, fair enough. the ROM is an alpha that is not released to Toroplus yet. the kernel is tuna faux123. the problem is when I plug in my thumbdrive I am unable to explore files. I even installed Stickmount from the market. it tries to mount the drive, to no avail.
Sent from my Galaxy Nexus using Tapatalk 2

so, besides the troll who popped in to flame me, does anyone have an idea about this? i am not looking for specifics, just a general idea about if USB OTG is controlled more by the ROM or more by kernel choice.

USB OTG is controlled by you. Just plug the cable. You're doing it wrong.
Now, that's me just trolling too.
Either way, maybe you can help me on one thing here. I have a 2005 Accord diesel. Can I use an oil filter from the 2007 facelift version?

you're right, you're trolling. move along.

So simple. You ask the questions, then give the answers.
It's because of your alpha rom? Maybe. Try another.
It's because of the kernel? Try another.
See? Simple. No one can go to your place and do that for you. Test, test, test.

C'mon guys...he just wants to know if anyone has used it successfully...if you can't answer why post?

Too specific problem. User should try other setups and give feedback. Be proactive, people.

just because you didn't know the answer, doesn't make it a flawed question. it wasn't too specific, it didn't require testing. someone out there smarter than both of us probably knew the answer. is the USB OTG function controlled by ROM or the kernel? instead of an answer i got my thread clogged with your smartass comments and non-answers. i'm sure if there's an opening in the question police squad on XDA you'll be the first to apply, but until then your self appointed opinion on the validity of questions in the Q&A thread isnt appreciated or needed. not by me anyway.

Make pancakes not war!

Hey noob, i'm not trolling. You asked which was more likely. I said maybe both, because it is!
Kernel because of fs support, rom because of vold and enforced permissions. Now go search and learn.

Ubuntu touch

I was wondering if anyone knows of plans on porting Ubuntu touch to the Zenfone 2 as it has an Intel chip and would be ideal for running Ubuntu also what do you at XDA think about it and whether or not it should be ported over?
I have used Ubuntu touch preview in the past on a nexus 5 but I think the Zenfone 2 might have great support for Ubuntu touch including the 4 gb ram and that intel chip.

Well I mean Ubuntu touch has there own apps every OS/ROM is different so you might use whatsapp on android yet there might be something Else on a ubuntu touch device thats similar.

Well I think Ubuntu touch would be an amazing port and would be an amazing ROM on the zenfone 2 4gb version then again not sure how many users on xda are but I am also a huge Linux fan.

I would love to test out Ubuntu Touch on our Zenfone. So far I haven't felt the need to move from stock after debloating it.

Most people havent but I mean the Intel cpu would be perfect for Ubuntu touch, it would also be interesting to see how the zenfone 2 preforms with the ubuntu touch on it.

me too LOL ??

Someone should complete "Multiboot project for zenfone 2" then we can dual boot other ROMS along with Android. That would be fun and many people including me would use it. Entirely leaving the Android ecosystem is hard.

I think ubuntu touch is still based on 4.4.2. (<-- I hope I am wrong on this.)
This might be a problem because the lowest our zenfone gets is ~5.0.
So there will be a few bits and pieces that won't work correctly.
Also ubuntu touch seems to be arm focused, making it a bit harder to port.
There are also some issues with the (cm13) kernel. (cgroups/app armor/where is logger.c?)
However this does mean it is impossible, it is just a bit harder than one would expect.
I have tried porting it myself but failed several times.
Next try: once I get libhybris working.

With that apart from ubuntu touch, you could also make a port of sailfishos.
PS: So do a topic posting the progress of the port?

I totally forgot about sailfishos.
...which is weird because I was lurking around the mer-hybris repos for quite some time now.
I am downloading the sources right now.

I'm looking for a port of these 2 operating systems for zenfone 2 which I bought it to have as a "linux handheld" but I still have not seen anything more than a simple chroot in android.
Besides that, I'm also waiting for someone to make a port of the latest version of linux (next to other things to make it a distro) to zenfone 2.
Please, if you have the knowledge of how to do it, do a favor to people to do it and publish it, I know it costs but if I would have the knowledge I would do it.

does this site still allow questions/threads/discussions about pocketpcs?

i know 2008 was 13 years ago and no website stays the same forever, but i know y'all used to be all about that kinda stuff back in the day, and considering how inactive other handheld computer/pocketpc communities are these days i figured i'd try my luck here.
so yeah. does this site allow questions about palmtops/handheld pcs/WinMo devices? and if so where would i post em?

Hello and welcome to this forum, indeed we have the "old" device sections where you're looking for:
Legacy & Low Activity Devices
forum.xda-developers.com
You'll find lot's of former devices with Windows Mobile etc.
Neewer ones are listed here for example: https://forum.xda-developers.com/all-forums-by-manufacturer
Otherwise just type the desired device within the search box on top of the website

thanks :>

oh... im afraid none of those subforums apply to this particular situation. you see, im not talking about a phone. im talking about a PDA (specifically, an HP iPAQ). no cellular technology in here except *maybe* the wifi but that doesnt really count. if i missed something pls let me know, cuz i really need help with this relatively obscure issue :/

You can always try you rluck and post on "General", maybe start something...
Like Make a thread called [DEVICE][PDA]HP iPAQ Development Thread and try to see if people come here. Your OP could be a place were you centralize all of the good input, links, development prospect about the device.
If you managed to develop something or have already some knowledge with that device feel free to share it within the thread. It may take time but once you gather a community around the device things starts to get interesting.
Of course it won't blow up instantly, patience is key !
