[Q] Re: Nexus S usb host is not working - Nexus S Q&A, Help & Troubleshooting

http://support.google.com/ics/nexus/bin/answer.py?hl=en&answer=2386439&topic=2375623&ctx=topic
According to the official Google Help Page, it should support USB Host. However searching online have returned a lot of out-dated threads about how the USB chip works when it was still running Gingerbread.
I have purchased a USB adapter, tried to connect any USB device to my Nexus S, and nothing happens. The USB port will not be powered. However quoting Google's official help text :
You may need an adapter to connect the keyboard or other device to your phone's USB port. To connect more than one USB device at a time, use a powered USB hub to reduce the drain on your phone’s battery.
This implies that connecting devices to your Nexus S will drain your battery?
I am very confused. I have no powered USB hubs so I cannot try to see if the USB host function is purely limited by the lack of power or the USB chip.
I am sure I am not the only person who would love this to work. Is there anyone who knows what does it take to get USB Host to work on Nexus S upgraded to ICS? (Despite Google's help site indicating that it should just works out of the box)
Thanks a lot.

So, I spent some money and bought a powered USB hub.
No it didn't work.
I think the reason is that the power is not being transferred UPSTREAM. For example, I have connected the USB hub to my Nexus S, and a Logitech wireless mouse receiver to the powered USB hub.
Although I am sure that the Logitech wireless mouse receiver has power (from the USB hub), the Nexus S does not recognize the existence of the USB hub, since the power is not transmitted from the USB hub back INTO the Nexus S.
Feeling disappointed, I repacked everything nicely and exchanged my purchase for a slightly more useful 16GB SD Card.
Does anyone has any information to how is this supposed to work?
Or should we assume Google has made a stupid typo in their help articles, and that the Nexus S will not actually work in USB Host Mode ??

anyone please?

I too am looking for answers. Anyone?

[Q] HP Touchpad OTG support?

So simple question, does anyone know (have tasted) if Touchpad supports OTG like for example Galaxy S2?
I bought these from DX: http://www.dealextreme.com/p/micro-usb-on-the-go-host-otg-adapter-pair-50774 and is working great with my Galaxy S2, but can it be used for Touchpad?
First, it is TESTED.
Second, Nope no native support yet, might have to wait till android port is complete, might take a couple of months.

One of those newbs who can't post links eh? I'll fix that...

The Touchpad doesn't have a powered port is the only problem - so provide power to whatever device and you're good to go.
what about a external HDD with its own powe supply, will it work..
unfortunately, i'm still waiting for my TP so cant test
Does it work with your HD2?
If so, there is no reason not to work with TP
(Hint: HD2 has same kind of usb host capabilities that needs external power supply)
So was it ever established whether or not USB OTG works on the Touchpad? Sorry to necro-post, but I picked up a touchpad during the firesale, have been loving it with first WebOS then CM9, and since I ordered a USB OTG adapter for my GSIII (this friday!) I was curious if there was anything I needed to know about using OTG with the HPTP.
It just works with a powered adapter. Nothing more to it then that. I've plugged almost everything into mine!

Thanks for the links, will see if I can get the needed cables etc from eBay/Amazon
Thanks for the help. My OTG cable and other things from Monoprice should've come yesterday, so hopefully I'll have them tomorrow. By powered adapter, do you mean something like a powered USB hub? Although I didn't get that OTG cable for the touchpad, it'd be a nice treat to be able to use it with that, it would definitely make moving movies around a lot easier.
EDIT (10/19): Dangit, they didn't come today. I'll have to see what's up, because they've been in my area for a while according to tracking just not coming.
Yes, u will have to use either a powered USB hub or get power from a USB charger that doesn't have the data +/- pins shorted internally (purchased or modified). If u plug device (ie phone) into charger and it says "ac charging" that means the data pins are shorted.

Alright, thanks. I think I need to get a powered hub for my laptop (which I am currently using as a desktop with external monitor and keyboard) so I there may be a happy coincidence here.
Also, just checked on my touchpad, and the HP charger says charging (AC) as well as my phone charger, which I think started life destined for some Blackberry.
The powered hub should work though, and that would make a great machine for typing and working in bed as opposed to my laptop burning my thighs off.

I just verified that if you get the Micro USB Host OTG Cable With USB power ($6 from AppleCable on Ebay) that Ramjet73 mentioned (or this one), it will work with any standard USB charger (ie the 1 Amp HTC or 2 Amp HP Touchpad Charger) because the USB Power Connector is Isolated. I also picked up Applecable's USB 2.0 3 Port Hub with data Sync Charger cable for $7 (I may try to modify it to be a USB OTG powered hub with this).
I will be updating the OTG thread I mentioned earlier. See attached:
I've never successfully used OTG. I've bought 2 cables.

I've received a bad one before. Cut it open to verify the id pin hadn't been tied to ground like it was supposed to be. I can verify that OTG is enabled with the CM9 Nightly and jcsullin's latest Cm10.

How to make nexus s support USB OTG -- somebody already success

any body successed ?
Bad news, there is no way to enable OTG
Because NS uses usb switch chip FSA9280A, and this chip doesn't support OTG.

I made a mistake, there is a FSA9480 in the phone, so it support OTG in hardware.

I haven't had any luck getting this to work.
I tried hooking up a USB mouse, game pad (wired 360 controller) and a USB flash drive. However nothing happened when I plugged them in.
I connected them using a micro USB to USB adaptor and an externally powered USB hub.
Since the Galaxy Nexus appears to support OTG without issues, I'm guessing it's not working on the NS because of some sort hardware incompatibility.

first of all, are you sure your kernel configure support OTG ?
and then, the "micro USB to USB adaptor " is type-A(pin 4 connected with GND) ?
btw, the cup(S5PC110)'s datasheet shows it support OTG.
Ah, I did not realize there were different types of USB OTG adaptors. Thanks for bringing that to my attention.
I did a bit of digging around and it seems that it's not too difficult to modify the adaptor from type B to type A, provided you have basic soldering ability (http://forum.xda-developers.com/showthread.php?t=1092493). Perhaps I'll give that a go when I get some free time.
Has anyone else tried this feature on NS with any success?
This only applies to the Nexus S i9020.
i9023 seems to user another USB chip (http://forum.xda-developers.com/showthread.php?t=1431151) for which are OTG kernels available:

SGS3, USB to go, and charging

I just recently purchased a USB to Go dongle for the SGS3 (the adapter allowing you to use the SGS3 in usb host mode, to connect things like flash drives, mice, hubs, etc). Everything seems to be working quite well, but I do have a question maybe someone can answer.
I was hoping that, if using something like a powered USB hub, that I'd be able to plug that into the USB to Go connector, and that my SGS3 would charge through the hub. Maybe this was a foolish hope, but I'd hoped nonetheless because it seems that there's going to be quite a bit of battery power drained by trying to power devices like this. I had hoped to basically set up a sort of docking station where I could connect the phone to the USB to Go adapter, plug that into a powered hub to have it charge, connect a flash drive, mouse, and keyboard to the hub, and then use HDMI out to a TV.
It seems even with a powered USB hub I'm stuck not charging so this setup obviously doesn't last long, which leads me to wonder why it's set up like this.
I'm sure I'm missing something or not thinking it through or maybe it's just not possible. But any insight into this, or is it just not possible to charge while using the phone as a host?

[Q] Help with USB Host (OTG)

Hi All,
I'm trying to get a USB device connected to my phone (specifically an OBDII reader with Torque Pro). No matter what I do, I can't get it to recognize on my Nexus S 4g. When I run USB Host Diagnostics, it basically says it can't find anything.
I'm running a flavor of Cyanogen 10 with its stock kernal.
My questions are:
Do I need to go through a powered USB hub to get the proper power?
Do I need a specific kernel with the correct host modules enabled? (if so, can someone point me to one)
Thanks,
Torque Pro worked fine with my NS4G with a cheap ebay bluetooth adapter with no hassle. That adapter had no batteries at all, it was powered through the ALDL port on the car. I couldn't imagine needing power since no scanner I know of needs power at the ALDL port, it pulls it from the port itself. I would bet it is USB driver problems, or problems reading the USB adapter through Jellybean because of this new MTP protocol that sucks
Good to know.
Should I try a HoneyComb ROM? I guess it COULD be the OTG cable I got from amazon. Maybe it's not plugging in all the way.
thx

No Honeycomb roms for Nexus S...
I highly suggest a OBDII bluetooth adapter. They're 15$ on the net and will spare you the trouble. Make sure you find one that has good reviews, some cheap ones have problem connecting to some cars because of broken J1850 PWM (i think it's PWM, might be VPW) protocol.

Split cable for charging and OTG

I am trying to charge my Nexus 6P while simultaneously casting a streaming video from a USB drive to a Chromecast using a USB keyboard and mouse (Basically a computer replacement scenario). I have purchased the Cynergy 3 Port Ethernet Hub USB C with USB C connector and everything works independently but I can not seem to get it to simultaneously charge and read the USB port data. When the hub is inserted into the Nexus 6P the phone asks me to choose between 5 USB scenarios (see attached picture). When I pick “Charging” the USB ports stop working and when I unplug the power supply and then plug it back in the phone defaults to “Power supply” and the phone does not charge but the USB ports work along with the items connected to them. So I wonder if simultaneous charging and data is possible with the USB C connector on the Nexus 6P? I have read elsewhere in this forum that it may not be allowed in the USB standard but can’t find any confirmation of this. Has anyone found a cable/hub that can do this or is this not possible due to the USB C connector limitation?
You might want to try something like this.

Why tell him to waste money on something that isn't going to work? The 6P doesn't support USB PD so this isn't possible.
i think you need to do some mad hacks in the kernel to get otg and charging at once (i think they did it on the oneplus 1 and possibly on the 2nd gen n7 so maybe google those for what it needs to be done?) i tried various resistors to the sense pin on the micro usb z4 which ended up not working but i have no idea how the usb c is wired up. Good luck with it anyway
