USB Host Not Working

Hi guys. So the only thing I've done to my i747 is root it. I've tried both of the USB host apps in the market (USB Host Controller and StickMount) as well as the "SGS3-Easy-UMS" apk that's around, v1.2beta2 and v1.3beta. Can't attach any USB devices. All my flash drives are FAT32 and work well normally. I even ran the USB Host Diagnostics app and it confirmed that Android API, Rooted API, and Kernel "claim support" but no device is detected.
When I connect to sync, I can only do MTP transfers. This is why I looked into that EasyUMS apk because it apparently also allows to mount the phone on the PC as a USB Mass Storage device. During my search I see numerous people connecting flash drives, controllers, keyboards, and even a USB HDD to their sgs3's.
Because that apk requires busybox, and I have busybox, everything looked OK. However, I did once get an error from that APK about possible non-existant Kernel support. USB Host Diags disagree, as do many video tutorials.
Basically I'd like to know whether or not this is supposed to be working, and if not, then how do I go about making it work? I'd like to mount flash drives for easier use with Linux, and would like to mount the phone as UMS for the same reason. I would also like to use a USB Keyboard as well as a USB gamepad. Am I missing something? Are they all using the international?

Are you using a USB OTG cable?

got this one, a couple good reviews confirmed that it works with input devices: Amazon product# B005GI2VMG
i mean it's very possible that the seller just buys from random manufacturers without changing the listing. this one that i have is like the cheapest thing on the market so that may be the problem. i wouldn't mind trying a different one for <$5 w/ US shipping if that exists (recommendations?).

Same cable didn't work for me
I bought the same cable, but from a different seller. Amazon ID number B005N55WHI
And I have the same problem. Tried using it with several input devices and with several different roms and I couldn't make it work. Could it be a power issue? Does the USB device that it is being hooked up to have to be powered? I tried it with mice, keyboards, and flash drives, but all of those devices take their power from the bus, not an external source.

glad you posted. hmm. since we both have the same thing and they're both not working, i'm suspecting it's indeed the cable.
i read on a review of a different cable on Amazon where the guy cut open the connector and found no wire connected to one of the pins. i've had thinner-cable wires before that charged/transferred slower than others or didn't work at all on some higher-end devices, could really just be a cheap-out on the manufacturer's end.
i think i'd like to get a different cable. if anyone can recommend an inexpensive one that's confirmed working i'd appreciate it. so i don't have to shoot in the dark.

I got the one with Amazon ID B00871Q5PI and it worked for me. I tried a Dell USB keyboard, a USB mouse, and a USB DAC and they all worked. All take power from the bus.

got this one.... http://www.amazon.com/dp/B005GI2VMG/ref=pe_175190_21431760_M2T1_ST1_3p_dp_1
would it make a difference if it says its for the galaxy s2 and not the s3? im guessing thats why i cant get it to work.

No, would not make a difference. USB OTG is a standard and for now all devices that have USB OTG work with all USB OTG cables. I've used a cheapass one from Ebay with my S2/Note/S3 for more than a year now.

solved for me
so i got the one drothenberger got (actually that particular link was out of stock for the seller so i got the other suggested one that looks exactly the same, title OTG for SGS3 - item# B00871Q5PI) and i'm in business!!!
someone replied to my negative review of the other one i got in the comments and they said theirs worked. i think they just have different products under the same label or lots of defective ones. i'd recommend to just get the ones that specifically say OTG for SGS3 - the extra dollar or whatever is worth it to save the trouble.
thanks again to everyone for the troubleshooting, hope this topic helps others resolve their issues.

[Q] Micro USB to Ethernet Adapter + Note 2 = ?

Hello,
I've searched the forums and made no conclusion whether this would work or not so I'm starting a new thread. So I'll be living in halls for some time and in the halls there is no wi-fi only ethernet cable and bringing a router is not allowed
So my question is will a micro usb to lan adapter work on Note 2? Has anyone tried it? And are there any other solutions to this problem?
Big thanks for any response. :highfive:

Unfortunately I wasn't able to get it work. I've tried several kernels, with stock rom, but no luck.

That's bad I read somewhere that these work with phones that support OTG cables but idk. Are you sure you tried a Micro USB adapter and not a regular USB one plugged in with an OTG cable?

You 're right, I've tried the regular with OTG cable! My fault ..

It's good to know it doesn't work with an OTG cable. Has anyone tried a Micro USB to Ethernet adapter and wants to share his thoughts?

Bump! ^:fingers-crossed:

I am able to get my usb ethernet adapter working by following this thread. Running on Omega V16.

Can u provide us a little more info? Which Note do u own, kernel, etc? Did u compiled something yourself or did u find something precompiled? Thanks!!

I'm using N7100 running Omega 17 (XXDMC3) standard kernel.
I used the precompiled driver provided by gingerneil in that thread and followed the steps.

usb otg on galaxy tab 3 7.0

is there any way to use usb otg on galaxy tab 3 7.0

Not working yet, but I am working on it now. All wiring is correct internally but the otg phy driver defaults to dock mode. Omce I patch it you will lose dock mode but gain otg.

hey

No problem, I should have it fully going in the next week or so as time permits me. USB OTG is pretty much a requirement for my final goals and i doubt anyone will miss the dock feature. So far my kernel recognizes devices via lsusb and prints vendor info but it might need changes in the rom as well which im gonna tackle now.

Wishing You Success

our tablet doesnt support usb otg so what the OP is trying to do is whenever you connect your usb, it will use the wiring and stuff of dock mode to load and use usb otg

so the microusb port has the enough power to power on one flash drive but its blocked by software... good

Yeah, any progress @BinaryDroid?

I know for a fact that officially the Samsung Galaxy Tab 3 7.0 does not support USB OTG via the official Samsung Firmware for the device. But I think you guys could get it to work if you use a custom ROM for the device.

This tablet really disappointed me.
The chipset supports USB host:

official for galaxy tab t110?
and if you could put him whether drivers usb modem zte such as to have 3g on the tablet via a usb modem? Thank you.

I don;t know how you can be disappointed about a feature the manufacture has always said would NOT be present.

You could also do it for the t110?
you could include drivers usb modem to connect a usb skewer?
I'm trying to do this http://www.htcmania.com/showthread.php?t=533210
but the tablet does not recognize the modem could make it work in a t110 please thanks.

I do not have a mainboard for the T110 to work on the kernel or to trace out the layout as I did on the T217. Officially the T217 has no a stripped down set of drivers and its alot of coding to trace the board layout to each GPIO, then get the GPIO numbers, write a shim kernel module to activate host(im hoping to do away with this when I am done), then link it into the ROM itself.....its not an easy task as you can tell.
PS: for the record I will not touch PXA devices lol, hate me or not I just do not like the PXA.

Which otg to get for z2 plus

I've come to realize that only a selective amount of OTG cables work on this phone, can someone please recommend some? thanks.

If you've come to realize that only certain ones work, then why aren't you informing us which ones?? I personally didnt know Z2+ did OTG but I guess ROMS can change this..

because i want to know aswell?

As far as I have tested or seen, Any USB C Type OTG cable or connectors work with Z2 Plus.
Here is one such cheap connector I am using for connecting my USB pen / thumb drives.
Working is more depended on data partition of the drive. Some time some ROM finds it difficult detect NTFS. FAT32 works fine most of the time.

Yes, I can confirm that USB OTG is working fine on my Galaxy A32.
