[Q] Possible to disable USB Host Mode? - One (M7) Q&A, Help & Troubleshooting

Hello everyone,
Here is some background information to give you guys indication of what's going on:
- Phone charges fine though HTC charger and USB.
- Phone detects MTP fine when connected to the computer and charges as well.
- When placed on dock (connected with HTC cable and charger), the phone says "can not charge in USB Host Mode"
I've scoured these forums and tried some of the solutions posted. My question is that is there any way to just disable USB Host Mode all together? I know based on my usage that this feature will never be used by me.
Thanks everyone

Exactly the same problem here
Any solution for this?
Thank you.

This (https://github.com/mehrvarz/android...mmit/6be86fe2c73f626630329982aaa7731525de6078) is how Timur made his Galaxy Nexus kernel be able to do this. Don't know if you could talk a kernel dev in to trying to incorporate this or not. Note: this method (for the Nexus, at least) won't power devices while in host mode but will accept external power via a Y cable

usb power tether

Greetings! I tether my celly for use as a modem but it uses battery power. I want it to use the PC power thus not draining the battery thus happy celly thus happy me Any thoughts??
You talking about Wifi tether? Because what I do is I USB tether and no power issues.
If I understand you correctly and Ive not tried it but can you not connect the phone via USB and and then wifi "tether" simultaneously?
Remember the thread about IntShrUI ? Just run this file located on the windows folder while synced and done!
"I think" I now understand the issue...
I got curious and tether my Phone over USB for a few hours while downloading a big file, the phone eventually died, apparently it uses more power during tether than the PC USB can charge "500ma". The only thing that comes to mind is that you could use a double USB cable that would provide 1000ma or wait for USB 3.0 cable and hardware which provide such already by default. Or a AC to 5v powered USB cable? That's all that comes to mind, unless you can hardware hack a PC's USB port to provide more power lol

Makes sense to me since a recharge via the wall plug or my car (vs. a USB port on my PC) is much faster.
tethering
I use the assasins lament WiFi router while using the AC usb adapter. I understand exactly what your are referring to. I have tried to use the dual usb cable that comes with the Imagio, one side for connection and the other for power, didn't work to well.
One major concern is while using the USB tether mode the active sync needs to be disabled, thats a bugger when you want to download and then perform an install.

[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.
I for one cannot wait to get my SGN2 smart dock which offers:
Charging
OTG (x3 USB)
Audio out
HML HDMI out
Docked Profile

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.

It has bluetooth... so in theory that could be a simple alternative... we just need to figure out how to access hidden menus.

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.

Please correct me if Im wrong, but the cable you linked only charges the thumbdrive/keyboard/mice/etc NOT the Chromecast so how would one root it since it does need power from usb plug? I've been searching for correct cable and cant find it; link to correct cable would be greatly appreciated!!!
This cable wouldnt work, right? http://www.ebay.com/itm/Usb-type-A-..._USB_Cables_Hubs_Adapters&hash=item4857e3608e

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...

Htc desire 626s usb otg capabilities?

Hi, i recently rooted my phone and used the Post in the forums to do so, here is a pic of the kernal and all that. My question is why can i still not use my otg? Downloaded host diag, checker, helper, nothing is working. Can someone please tell me where to go from here? There are spaces so i could post the url.
http ://i63. tinypic. com/24ys9z5. jpg
seems kernel doesn't have the driver for it also the phones board doesn't supply power to the cable so you would need a y cable to supply power. Im still waiting for HTC to post the kernel source so I can make the modifications I need to it. It's been almost a month since they said they elevated my request for the source to their dev team if its not posted in a week I'm going to write them again.
There is a app I saw the other day called "stick" something that enabled phones with no otg support to use one. It was in a YouTube video about must have root apps , sorry I couldn't help more than this. I did order an otg cable after watching it.
Ok, ill look to see if it works
Nope. Still won't work. Power must be supplied for it to be registered to the phone.
E]Well i bought a powered otg y cable plug in usb portto charger the other end to my phone and the other to my usb 128gb.. nothing
still diesnt detect but it does on my samsung . So it must be the phone not the cable

I had no luck with a powered Y-cable either. I got OTG to work with my XT894 only after connecting a powered USB hub to my OTG cable, then connecting a USB flash drive to the hub.

Note 5 Keeps Disconnecting & Connecting Via USB Cable

Hello...
My Note 5 Keeps Disconnecting & Connecting rapidly Via USB Cable? I have tried to seek solutions by disabling power management in USB Control but to no avail. Does anyone ever have this same issue & share how to fix this? Thanks in advance
Ihad this problem before. And i found that the problem caused by the cable itself . The note 5 cable is so thin and as you moving it , it will disconnect. I tried to connect my note 5 with old s5 cable . (Thicker one ) and the problem never appear again . Hope that help .
I agree, I had the same problem and found out it was the USB cable itself..

Hi,
Firstly, i agree with other posters that it could be Usb cable. However in my case with my old Note 4 I had similar issues with connecting /disconnecting.. rapidly (same as you stated in your post)
I found in my case it was the Note 4 fast charger plug (Not cable.)
If i changed the fast charger plug it would stop disconnecting /connecting. In fact it made a loud
noise /sound in the process that drew my attention as to what was happening. (the phone was making the connection /disconnection noise)
If i changed the charger with my old Note device's charger/ plug it would work correctly. Also if i change
Note 4 fast charger with my Note5 fast charger it would also work correctly.
Good luck
Well...it's getting quite weird actually. Yes i think the problem is actually from my USB cable here, it used to be fine but problems only arose after i upgraded my PC OS from 8.1 to Windows 10 and Note 5 firmware to Marshmallow at the same interval. In my case the charging process with its fast charger adaptor works fine, but not with the data transfer when connected to PC. Since i only have other USB cable from Samsung Tab S, thus what i can conclude is that by using said USB cable, connection to PC was more stable but still sporadically undetected or stopped during data transfer here. And it did not support fast charging despite plugged to Note 5 fast charger adaptor. I suppose not all USB cables support fast charging at all. And there are reports indicating several USB problems conflicting with windows 10 as well. Meanwhile i am still trying to figure this out, i'll keep updated when new progress comes up ok. Thanks for all your attention & inputs, really appreciate it here.
Just bought a new USB data cable for Samsung Note 4, the cable is indeed thicker. Conclusively yes the culprit was the USB cable as no said problems occur anymore while using new cable here.
