How is the USB OTG supposed to work?

I downloaded Nook Tweeks, enabled USB host mode and External vBus, but nothing happens when I connect a USB-stick via a micro ubs to usb converter.
Am I supposed to do something else? Or does the USB-stick have to be in some special format?

I got the same exact problem. It didn't seem to work at all.I think I'll have to order the adapter to see if the problem is the OTG cable or not

I ordered some cheap ones from DX, but since there are two of them and none of them works I'm assuming it's the Nook the problem is with.

It could be the USB-sticks are trying to draw too much power. The Nook host port will only supply low power USB devices (<100mA) and it is also best to have a fairly well charged battery. Some sticks work and others don't.
If you have a powered USB hub then this supplies the power so there is no problem. So try with a powered hub to at least see if that is the issue.

I used the same USB in this chart Nook Color USB HOST Device Compatibility List Sandisk Cruzer 8GB on CM7
I bought the Nook Color is to connect it to my camera via DSLRcontroller but so far still not successfully with USB stick.

Read my thread , it should answer most if not all your questions

I'm hoping to get some free time and update it this weekend with more info and probably a widget

I could never get usb host working on cm7. I have been trying to use RYC usb to control my Nikon Dslr . Once i switch over to CM9 beta it worked first time.

CM7 also shouldn't give you any trouble , as long as its FAT32 and you are using a hub
can you explain what exactly have you tried and provide logs?

I didnt use usb hub,just enable the usb host mode in Nook Tweak app and plug my usb via otg cable.

Then you didn't read good enough the thread or the chart..
You need an external hub ( powered or non-powered ) to work with the sandisk cruzer.

Thanks a lot, i ll order one and try it out.
I tried to connect with my camera but nothing happened,I guess I have to try with usb hub as well

[Q] USB OTG: usb1 found, cannot use keyboard

Hello,
I have a USB OTG cable and dell keyboard that I have tested and work in OTG mode on a Nexus 7, however i cannot get them to function with my HP Touchpad 32gb, running CM9 2.6.35, built on Sun Oct 28.
The device recognizes when I plug in anything via USB, but only as a generic Linux USB hub, and not as any particular device. Are there any steps to take to debug this? Has anyone had experience with this type of an issue?
Thanks for your help,
Cory

I don't know if this is the issue, but I know the touchpad doesn't support OTG like the the Nexus does. I think you need a Y-adapter + OTG to provide power since the micro usb port doesn't give any power to the device you connect. Someone correct me if I'm wrong though.

Apparently even a powered USB requires a powered Y cable to be properly recognized. I hacked together a quick Y cable manually, by splicing in another USB cable's power and ground (Red and black) to the respective locations on a female USB cable. Works as expected.
I am now communicating with an Arduino over Serial
Thanks!

Read this thread, should give you all the info you need:

Basically the Touchpad has OTG but it provides no power.

Agreed. I think people just are not stating reality regarding the ability to charge and use OTG Hosting to USB devices at the same time.
My goal here has been to attach a flash drive with video/audio media and play & charge on long flights. It looks like play, charge are mutually exclusive on my beloved TouchPad.
I've asked for the specific confirmation of this from this YouTube but have never had the poster reply:

There are devices out there that have very advanced micro USB device implementations. Sadly the HP is only superficially supportive.

Galaxy tab p1000 and USB Mouse

Hi guys.. i've searched around how to make works usb host on our p1000.. i've tryed several roms and now i've cyanogenmod 9.1.0 since it support usb host and it works with Y cable!
now.. i'm using a self powered usb HUB.. connected to tablet through an usb female to female adaptor and official Samsung data cable.
so.. i've downloaded "Usb Host Controller" app, under "setting" tab i've selected "usb host mode" and now under "USB" tab i can see 2 devices ("1-1 USB2.0 Hub" and "1-1.4 USB2.0 Hub"). When i plug in an usb Stick (2gb) i'm able to mount it and browse through File manager with no issue.. but when i plug on hub an usb mouse.. tablet doesn't recognize it in any way! the mouse optical light turn on and turn off after a few second.. i've tried with two different usb mouse without success!
Any suggestion?

Hi.. i'm using official CyanogenMod 9.1 Stable ICS with kernel inside.. nothing special to do.. just download "USB Host Controller".. switch to host mode.. then plug your selfpowered usb hub or an Y-Cable with a power connection, since our tab doesn't provide enough energy from 30-pin port! but only USB Stick work for me.. nothing to do with other devices like mouse or keyboard.. for screenshot i can post it tomorrow!:good:

Hi, are you just using the standard samsung cable? AFAIK, usb otg cable must be used. Anyway I will wait for the screenshot and if possible a photo of your setup. Thanks

First of all thank you for your answers. Is this the configuration then:
1 Y cable (2 male, 1 female), 1 gender changer (2 female inputs), 1 tablet charger cable (1 30pin input, 1 male USB)
I guess that I should connect 1 male input of Y cable to tablet charger, the other male to gender changer. The remaining input of the gender changer will be connected to Tablet with its charger cable. Female input of the Y cable is left for mouse, USB memory, etc... If this is a true set up, could you please tell me what exact version of Android, kernel, etc you are using. The link of the ROM (CM9, CM10, etc) will be very appreciated.
Thanks again.

Hello @nogo8888
i've read your previous posts that you have experienced using USB OTG with mouse and keyboard functional on your Tab?
I own P-1000 either and already installed the latest ROM from HumberOS (that's the 06-2013 update) and trying to mount my devices such as keyboard and USB mouse, with USB Host Controller (by sztupy) but i have no result.
if you don't mind please kindly help.
Thanks for advance, greetings from Indonesia

hi
the best way for mouse and keyboard use the Bluetooth mouse and keyboard

USB Port

Does the USB port have any other function other than power?

Don't think so, only power AFAIK.

I plugged it into my computer and even tried pressing and pressing/holding the button on the Chromecast but my computer didn't indicate any hardware plugged in.
I wonder if the data pins are even wired to anything internally.
UPDATE: The USB cable that comes with it may not work for data transfer, tried it with my phone and it didn't work. So I tried a normal microUSB cable but still nothing.

I tried this with a self powered USB OTG cable, just to see if the Chromecast would blink, bing, or do anything to show recognition, no dice. Also tried booting with a USB drive in, no difference.

Examining board
Based on examining the photos of the motherboard on ifixit.com...
Component EM1 appears to be a USB Common Mode Choke. That goes on the D+/D- pair which you can see routed from the USB port, so it wouldn't be present if there wasn't some use for data communication over the USB port. (Cost sensitive equipment.) The flip side of the PCBA shows TP1-TP20 (Where TP19 and TP20 appear to be GND). My guess is in that mix you have a JTAG port for programming/testing the unit initially with a pogo pin rig (evidenced by the dimples observed in each of those locations), and there might be more high/low GPIO pins where one might allow the unit to enter its USB data mode.

Looks like its already been rooted. With what looks like a dual usb otg. They don't go deep into what specific cable but, I would guess it is a generic dual usb one off ebay, or amazon, heres a quick one i pulled from amazon http://www.amazon.com/Micro-Cable-P...8&qid=1375052489&sr=8-3&keywords=Dual+Usb+otg
But if you read into it, they say you can root, but unless your a developer you probably wont get any benefit of rooting....yet, if at all.

I own that cable from Amazon and it should work. It brings in +5v from a charger connected to the female microUSB port and then splits it to the female full size USB port and the the male microUSB port so both the USB host device and the USB peripheral device are getting power.

I also bought that powered OTG cable off Amazon and it will power the Chromecast as well as provide the means to flash the Chromecast via a USB thumbdrive. When you apply power to the Chromecast, it automatically flashed the bin from the USB drive. There was no interaction required (or even possible). Of course this was on the original firmware - if your Chromecast updated itself, you have lost the ability to root the device at this time.
Clearly the Chromecast does sense the USB drive and pulls data from it during the initial boot sequence. However I'm not sure if it would ever work for other devices such as keyboards or storage devices, etc.
I'm not sure why anyone would want to hook those types of devices up to the Chromecast however. Once you have root, you can telnet into the device, so adding a keyboard doesn't seem that important. The whole idea of the device is that you send it media from other devices and control it via that other device. Adding storage for example doesn't seem important since it can pull media off the network already (ie a NAS or another computer).
Anyway. That has been my experience with it so far. It's a long winded answer to more than just your question about the OTG plug.

I would personally love the ability to send audio out without having an hdmi TV be on through the usb somehow...

[Q] install iodak v10 kernel on cm 10.1.3 stable

hi everyone,
i'd like to use the iodiak v10 kernel because it has the usb to go feature.
I need this feature to build a module for the pcan-usb-adapter. i need it for my bachelor's degree.
i updated my stock p-880 to cm 10.1.3 stable cause the stock system lagged horribly.
it worked without any problems. but after that i tried to install the iodiakx3_v10_cm kernel and it stuck on the lg logo so i switched back to cm kernel.
i alwas wiped all the caches.
since i cant write in the suitable developer thread, i hope i get here some help.
thanks in advance

If it was for my degree, I'd get a real OTG-supporting device. What we have here is a hack and it's not stable enough IMO.

well it's worth a try ... if it's working i'd be happy because i can save money and i dont have to wait until the company provides me with one (this takes time and i have only 1/2 semester to finish it ).
the problem is, there are no reports on the original kernel thread that v10 has installing issues so i assume only i do something wrong.
initially i wanted to use EternityProject Kernel 3.4.37 but sadly its dead.

2) connect phone to power (charger or USB)
3) unplug charger, connect OTG cable and then connect device to it (like USB mouse)
4) plug OTG male cable to power (USB or charger)

after that i connect via otg cable a normal microsoft wheel mouse optical (super fancy ) and nothing happens, no light from the mouse or else, same from a cherry keyboard or usb stick.
even with a powered usb hub between otg cable and mouse nothing happens.
do i have to use a certain app / programm ?

Yes, you need a USB Y-cable with external power support. After it you can disable external power, but it is needed in the first place.

i've used otg with y usb host cable and it worked.
this is short summary:
1. have your phone with you but not connected to charger
2. change the line from 0 to 1
3. plug in charger, and unplug it
4. plug in your otg y cable, and then plug in your mouse/usb stick*
5. plug in the y cable into computer/charger
6. unplug it after you confirm the mouse/stick working
*
in case of using usb stick, you gotta mount the storage after you plug it in. there are several apps that should be able to do this on the market, so check them out (i used stickmount)

thanks both of u.
today i learned USB Y-Cable != Powered USB Hub.
i tought the outcome of both solutions would be the same but i was wrong (a work mate explaind it in short to me).
i guess i cant hide myself of reading the otg specifications.
i made a usb y-cable myself and tried the steps with it but it also didn't want to function.
i wanted to provide pictures of my selfmade cable but it seems the pictures are corrupt (cant transfer them from handy to comp, i try it later again).
just to make shure i did it the right way.
here in short what i did:
- opend carefully a usb extension without damaging the small wires in it.
- soldered a male usb plug to : shield, red, black ( didnt do anything to white & green).
- no wire or shield of the extension were cut trough, only carefully opend.
i tested it so far only with a mouse & keyboard, but the usb stick will soon follow.
maybe there are issues with the cm-nightly ? -just a guess-
but i will later try Flying_Bear's steps to make shure i didnt miss smthing.

here the pictures
