(OTG) On the Go Flashing using usb stick!!

--------------------------------------------------------------------------------
I love this forum. I have learn't so much so far, but still have a lot to learn. Epecially programming for WM. Anyway, on to the reason for posting this thread.
Since learning that I could flash from my microSD card thanks to the tutorial by renaming the *.nbh to KAISIMG.nbh and placing it in the root folder. I have been making custom 1st splash screens to flash remotely as well as making a directory on my microSd ("Flashing from MicroSD") and creating directories for original roms such as (\WM6 Originals\Alex\KAISIMG.nbh) or (\WM6.1\SleuthV3\KAISIMG.nbh), (I also have KAISIMG for just Radios under a different folder) so when I want to try a new rom, flash a different radio or splash, I can at anytime.
Here's the thing I love using the splash tools (maker and converter) and Rom Builder. But obviously you need a PC. Would anyone by able to recreate a mobile version of these tools so we could do most things (customisation wise) whilst we are mobile.
I.E. I want to make and flash a new splash whilst mobile from a *.jpg. I could use this program to convert to .bmp format needed, then convert to *.nb thsn to *.nbh. I could then use a file manager to rename to KAISIMG.nbh then place in microSD root folder and flash.
What you think? Would this be too hard to do? Anyone want more mobile control of your mobile customisation?
Other tools that could be ported would also help. I make the welcome.96.png with my mobile graphics problems.
Well for the moment I'll stick to making several themed splash into the KAISIMG.nbh to flash remotely (making sure you have enough battery mind/dont flash on 10% or something/I recommend over 10% for mobile flashing your splashes and over 50% for you WM Roms)
Got a collection of around 19 Slide out Keyboard sounds inc Knightrider, Thundercats, Xbox 360 boot sound and others. When I have a couple more made I'll post my Sliding keyboard Sounds.cab if anybody wants it over the next Couple of days. (Some sounds gathered from other users share i.e. Mario etc) See this post for my collection of sounds: http://forum.xda-developers.com/showthread.php?t=372999
Thanks anyway. Feel free to post your views and look forward to seeing if anyone is up to this challenge..

OTG
Ok, here I go again. How about this??
I have a mini-usb to female USB connector which came with my Archos AV700TV for OTG (On The Go). Which allows me to insert my 4GB usb stick into the Archos. Where I can play, copy, delete or edit anything on the stick.
These connectors don't cost a lot and in my point of view would be a great advantage to those of us that want to Flash our Roms and Splash screens etc whilst we are at work or as a passenger in a car. I would like to leave my memory card with just my programs and music.
By having OTG on our devices I/we could keep all our KAISIMG.nbh (Orginal Roms, Custom Roms, Roms we are trying, Radios, Splash) All on a Usb stick, just lease a Maximum of 150MB on memory card. So that when you want to Flash a Rom. You connect your usb stick via small (mini-usb to female usb) into Kaiser (or other/I'm not Phonist) And use either an already existing filemanager (Resco/Total Commander etc) or created app (developed for sole OTG purpose) to copy \Custom Rom\Alex\WM6.1\Version 3\KAISIMG.nbh to the root of your memory card. Disconnect usb stick boot into bootloader and flash image.
You could also keep all your backup .cab files on the stick and perhaps ask the writer of Tier Auto Install to allow these to be read off such a device as a usb stick using (OTG).
And at only a guess if OTG was created for our phones I'm sure they could possible support higher size usb sticks than our microSDHC cards.
Only an Idea though. CAN ANYONE HELP?????

The USB OTG protocol is a hardware thing. Most WM devices do not have the ability to host a USB port, and so cannot initiate the connection needed to acheive what you want.

Never Mind then just thought with it being (Universal Serial Bus) I thought we could perhaps do something along the lines of WM5Storage. Thought it'ld just be a driver plus writing a relevant protocal script.
Thanks for the input anyway.

Gonna, try and by a cheap otg hd with built in led and see if it picks up the phone, maybe using the WM5Storage program so the otg hd might recognise it as the otg drive would be the host and has the hardware.
Even if it works, a bit bigger than something that can be carried around the neck...

Yeah, tried just now it comes up with portable storage device connected, but has some kind of error "USB Device could not be read correctly. Please try again".
It charges my phone though, so that a positive at least. Can use it as a portable battery pack as I take my archos everywhere. And I can charge that at work.
Maybe the error is caused because the phone has multiple memory types: Flash, microSD. Maybe it needs some software to point it in the right direction.???

Even when using WM5torage?

Yes, I have version 1.8. Don't know if this is recent and I'm using WM6.1 (Sleuth V3)
It reads card via card reader though via otg.

Ah, Softtick Card Export Works fine direct to archos. Still not quite what I was after but would sufice.

I gotta get me one of those...

[Q] Using desktop/Laptop as a USB drive for Update

This is kind of a question and also kind of a suggestion.
I have seen a lot of info in the forums about using USB Host cables to update xooms, but I have heard no mention of using your PC as a USB drive for the update. I am sure there is probably a good reason for this, but I thought I would ask anyways and see what the response was.
Is it possible to mount your PC hard disk, or possibly a USB drive that is plugged into another port, on the xoom and place the update file there? I tried Googling some info on doing this but was not sure what I should be looking for.

You could put a mac in "drive" mode and do this... in fact, I'm going to try it now... thanks for the idea!
* edit: since my mac drive is hfs, I'm betting it won't be readable by the xoom.... do I care enough to repartition a small section to make it FAT32? nah.

No this won't work for a variety of reasons. Honestly the crazy ideas people come up with just to avoid rooting.
Sent from my Xoom using XDA Premium App

Well I would root, but I use my xoom in such a manor that I am not willing to risk having it out of commission for a few days, if something was to go wrong.

I think using a USB hub would work. Haven't tried though. But the principal is you have your xoom usb cord and plug it into the hub. Then plug your FAT32 USB into the hub. Now they are linked together. Hubs are cheap and can get them anywhere and most likely you have one and its worth a try. Let me know if it works.

I'm pretty sure this wouldn't work because you have to boot your xoom from the usb device you are using, basically like way back when, when you use to have to shove a floppy into a computer before starting it to redo some of its bios work. You're basically trying to load an "os" like file from your external harddrive (well a flash drive really) and pluging the Xoom into your computer is a whole other concept.

3.1 & USB Peripherals

I know that 3.1 added support for a broader spectrum of USB devices, and I thought it would be interesting to compile a list of what works and doesn't work!
So far, I've tried:
ACER LIQUID E - Basically just charges the phone and allows for tethering (wish I could mount it) **UPDATE** After rooting and installing busybox and drive mount, Liquid E is able to mount! (Thanks, entropy)
HP WIRELESS MINI KEYBOARD (Model #U10G) - Works flawlessly! Prior to the update, only the keyboard worked, but now the mouse works too, as expected!
SONY CYBERSHOT (Model #DSC-W55) - At first the Iconia didn't detect it, but after I went into the camera menu and changed USB connect mode from "auto" to "mass storage" and plugged it back into the tablet, the Gallery app opened automatically and the pics from the camera magically appeared! Woohoo!
LOGITECH ATTACK 3 JOYSTICK - Not too useful, but it works! Basically it works as a glorified mouse, scrolling up/down/left/right. Pretty basic for now, but perhaps a good flight simulator will come out in the future?
SAMSUNG STORY STATION 1 TB HARD DRIVE - My biggest disappointment... I know there are workarounds to get external drives to work, but I was hoping 3.1 would provide a fix for this. It is formatted FAT32, so I'm not sure what the problem is, but my Iconia isn't picking it up **UPDATE** After rooting and installing busybox and drive mount, Story Station is able to mount! (Thanks, entropy)

I can confirm the iphone 3gs will charge and you can import photos/movies taken on the camera.
I have a cannon camera at home. I know they have a strange interface which always requires me to load a separate driver in windows. I will test it later and let you know.

No idea - would probably involve a rooted device and a custom rom - head to the dev section.

Logitech mx510 and mx518 mice confirmed.
Xbox 360 wired controller works but found no games that use it and it is very clunky for nav'ing the UI in general.

Is there a safe way of removing these usb devices without having to power down?

A "safe" way? I'm pretty sure it won't explode if you just unplug them.
In all seriousness, you should be able to just unplug them without losing data. At least I always have.
Correct me if I'm wrong, but the reason you have to "eject" removable media from windows is because windows has some sort of drive caching to speed things up. This means that just because you have copied a file to your usb drive, doesn't mean the data has actually been written right away.
Furthermore, Windows also locks out files that are in use by an active application. As such, windows makes you "eject" the media in order to give the OS a chance to check to see if any of the files are still in use, to avoid the application having a brain fart and crashing. Also, if an application is in the process of writing to a file and you yank out the drive, the file could become corrupt.
I think both scenarios are not likely to occur on an Android tablet, mainly because its based on a real operating system not designed to treat you like an idiot. Just make sure none of the data is being used by any open apps and you should be fine.
That being said, always make sure to keep backups.
Cheers,
-PW

Anyone able to use an Xbox 360 controller. I have a wireless with PC USB dongle, would like to use it if I possible.

Just want to say i can see my files in my x10 mounting it with drive mount and view it with file expert

Hello all
Just bought one of these off the net for the missus so ill be active around these threads as well. Personally i have a xoom this will be like my second to flash the heck out of lol but as I've been reading about these i have a couple small questions
1. Is the sd card working on stock rom so i can flash customs or will an update to 3.1 be required like the xoom?
2. Does the usb port work as host out of the box?
3. Whats the general stable oc you guys are achieving?
I have tried to search these but some are hazy on the specs or they are outdated

Fastest claimed speed is 1.64ghz, stable closer to 1.5.
SD card does work on stock, actually is required for flashing. As yet you can't flash from on board only external.
USB seems to work for some devices not others depending on whether you use the full size USB or the mini. Look on the market for USB mount all, you do need fat32 not ntfs though
Anyone want to contradict any of this?

Cheers mate thats good to hear except for the host feature thats the whole point hoppwfulky i get a good one

Yes USB host [the fullsize USB not the mini] works out of the box. If your USB device requires power though - like some external HDD's - it may not work as there might not be enough power draw.
The mini USB is for the connection to your computer and SDK/ADB/general File transfer use - along side the Acer USB driver install [so make sure you've got the Acer USB driver installed on the computer(s) you plan on using to push files to the tab though mini-USB].

Yeh as i said im well advised due my xoom on rooting and android adb, drivers (not being a know it all smart azz) just those couple q got me thinking.. Thanks for a second opinion seems very similar to xoom. Shame how host cant produce 5v at 500ma it wouldnt be to hard for them to up the lousy 3.7v it seems they are running now

Summary of limitations with Stock Firmware

Putting these out there so that dev's could address and all others should be aware of:
- No "USB Mass Storage" support. ICS out-of-the-box doesn't support this, however it can and has been added into ICS-based roms for other devices. Definitely possible to be addressed via software.
- Cannot move/install apps to the external microSD card. With ~4-5GB of available space on internal flash memory, this can become an issue for some.
- supports only microSD formatted in FAT32. Which effectively means if you have a video or other media file that is over 4gb in size, you cannot copy it onto the card. This is certainly a problem when you have HD quality movies you wish to play back on the device.
- wifi "can be" flaky. Many have experienced "low" wifi strength while only a few feet from their routers. Possibly could be improved through kernel driver updates, etc.
Please add on to this list as you come across limitations!
[EDIT]
- Per Macadamia Daze: Lack of Ad-hoc Wi-Fi support
- Per doraemon14: No face-unlock enabled in ICS
- [ CONFIRMED WORKING ]: Support for USB OTG (Host Mode).

I'm not sure who all cares, but it lacks ad hoc Wi-Fi support.

this is my first android device so not sure if this is only for ICS or all other previous versions.
- hope charging via USB is working even though it is not power-off.

Most tablets now need 2A to charge, USB only provides 500ma. I don't think it works, it's not an ICS limitation.

thanks for the info. just assuming (more on hoping) it might also work while on power-on since charging via USB is working if the device is turned-off.

as far as the - supports only microSD formatted in FAT32. Which effectively means if you have a video or other media file that is over 4gb in size, you cannot copy it onto the card. This is certainly a problem when you have HD quality movies you wish to play back on the device.
I found that if you use a rar. format you can break the file up into small file. which let you put it on the sd card and then extract the file and put it back together in the card. it may take longer doing that but it works.

Bluetooth issues... device tends to pair and connect, then randomly disconnect, say it's still paired, then constantly pop-up the "Pairing" dialog asking for the PIN number. Once this happens the device will not stay paired.
This is happening with my PLX Kiwi OBD 2 adapter in my car... happens to my friend on the stock original firmware (I'm on the updated version) we're both rooted.. this happened before rooting as well though.

[Guide] USB Host
--------------------------------------------------------------------------------
USB host lets you hook up external USB devices to your phone, like a keyboard, mouse, USB drive, etc..
Unlike devices which are designed to support USB host, the One S doesn't provide power to the peripheral. That means we need a few more adapters/cables to get it to work (and we need an external power source).
Purchase links are listed for all the required cables/adapters.
You will need:
•USB Host adapter (The otherwise unused 5th pin on a micro-usb connector is grounded) dx.com/m-129671
•Mini USB power Y cable (this kind of cable is often packaged with portable hard drives) dx.com/u-65630
•Mini USB Female to USB A Female adapter This package comes with two, but you only need one. dx.com/u-55613
•Your charger
Assemble the cable:•The micro USB of the "USB Host adapter" connects to your phone.
•Your peripheral plugs into the female end of the "Mini USB Female to USB A Female adapter"
•The "Mini USB power Y cable" has three connectors:1.Mini USB connector - connects to the "Mini USB Female to USB A Female adapter"
2.Male USB A Power (the thinner wire) - connects to your charger
3.Male USB A - connects to the "USB Host adapter"
That's all. As long as your ROM supports the peripheral, it will work.
Some fun peripherals to try:•Powered USB hub (You can also power the adapter from one of the hub's ports)
•Keyboard
•Mouse (a cursor will appear on your device)
•USB flash drives and USB hard drives must be FAT32. You have to run a few commands to use a USB drive. Mount manually from the shell (use Connectbot or Terminal Emulator):

UPDATE on BT!
I just called Samsung Mobile Support and let them know about my issue. I mentioned that the original and current firmware's both have this problem, the agent put me on hold for a few minutes and came back saying that they are aware of this issue and the next firmware update (OTA) should be resolving it!
Thank you Samsung for having great customer service (I was only on the phone with Samsung 12 minutes total, including the non-existent wait time!)

yeah, recap:
you:Im having a BT issue
sammy: please hold, *call developers on other line* *yelling at developers* Bluetooth is broken! fix it!
sammy: *back on call with you*, we're aware of the issue and will be fixed in an OTA update.

Did you test any of this for this tablet? Does it even apply to this tablet (you are referencing a different device)? USB OTG (aka Host Mode) is a combination of having the right hardware + the right modules compiled into the kernel.

I found that if you use a rar. format you can break the file up into small file. which let you put it on the sd card and then extract the file and put it back together in the card. it may take longer doing that but it works.

FAT32 has a single-file size limit of 4GB. Yes, you could use rar or any other archive format to break the original file into pieces, however for example, an HD .mkv video file can be well over 5GB (single file). You could possible copy 1 of those large files into the 'internal' memory if you had the space -- but defeats the whole purpose of having expandable storage.

i dunno whether the one i write here is considered as flaws or not...
i don't like the way this tab arrange its homescreen and apps cabinet...there are some spaces left and can't be filled...i hate this...

I had the same problem along many others(on original firmware it wasn't even usable it rebooted constantly). I was trying to connect to one of this:
http://tunerstudio.com/index.php/cablesandbluetooth
I ended up returning the device as I mainly needed it for that a the moment and as it crashed using the browser etc, but thinking of buying again.
Did they give you an ETA for the update? Or have you tried another ROM?
Post up if you get it fixed

Understandable if you needed it working right at that moment. I did ask for an ETA but unfortunately he said he didn't have one... he did say that it will be soon and to make sure my device is on wifi and ready for an update soon.. but I'm on a rooted stock firmware and froze the software updater lmao so that won't work... but I'll keep an eye out for am update and let everyone know. No I haven't tried any other ROMs yet as they all have some flaws that bother me... not too mention for my specific use I don't really need anything too fancy... just need BT for my PLX Kiwi OBD adapter for my cars diagnostics

is there anyone has stock room for p3100?

It's still too early, but there are some ROMs actively being worked on (and I'm hoping we see official support for this tablet from CM soon). With the recent MacMall $219 flash sale on this (they must have sold thousands in one day), and attractive MSRP, there could be a lot of interest from major developers.

Ebay tells you how much have been sold. It wasn't 500ish last I saw shortly before it ended.

I purchased the Samsung OTG cable and plugged it in the port. The cable has a female connector on the other end. I plugged in a 32GB thumb drive and it read it right away. I plugged in a small harddrive and the tablet reported that a high power device was plugged in and would not work without additional power. I paid $8.00 for the cable on amazon.com.

Would you be able to provide a link to that cable?
Thanks for the info! Does a mouse/keyboard work with no issue? The USB stick -- did it auto-mount and what filesystem is it formatted with (ie FAT32)? -- I'm curious if for example a USB stick that is formatted in NTFS can be used..
On another note, this confirms that the device itself can handle USB OTG to some degree -- meaning the modules are in place in the stock kernel and the hardware itself is capable of putting out enough power to handle certain devices.
