Yes, I know this question has been asked many times. But I'm pretty sure this exact one is new, so please don't remove this!
Anyway, I ordered a USB otg cable for my Asus Memo Pad HD 7. But I ordered one with a third plug to supply power to the mouse/keybaord/usb drive, as I read it needed that. And mice/keyboards work great! No rooting is required, just "plug and play"! But USB drives don't show up (there's even a folder called usbotg) and I'm not sure why. If they simply need mounting, is there an app for it? I'd rather not root right now since I just replaced a hard bricked tablet and that's never fun. Thanks!
Is bumping allowed? If it isn't please remove this, but this is on page 8.
Nothing yet? There has to be some ideas, please let me know if you have one!

Hi,
I did a search on this forum and on google but couldn't find an answer to my question.
I'm thinking on getting the eee pad only and without the dock for android game development. But since i'm new to android programming i need your help to clarify somethings for me. My questions is:
from what i read the eee pad doesn't have USB port. how do i run adb to it then? how do i upload my apk?
thank you for your time.
cheers!

The Transformer pad doesnt have extra usb ports for connecting other devices to the pad. The docking station has 2 extra ports that allows you to add other devices to the transformer (like USB pens, USB HDD, Etc etc). The Pad comes with a USB cable that is for charging and connecting to the PC. Thats the cable you shall use to upload files to the TF and use adb on.

It doesn't have a host usb port without a dock. You just plug in the usb cable that comes with it to the connector on the transformer, and plug in to your pc.

Lol.
But using the charging port i can mount the tablet storage on computer right?
Also has anyone tried connecting the mini HDMI to a TV or LCD Monitor? as far as i know tegra doesn't have hardware accelerated h264 decoding? and from what i read the best you can get is 1080p using baseline encoding? please correct me if i'm wrong
cheers!

You welcome.
Yes the charging port is like on the Ipad a normal usb plug. Ofc you cant charge the TF at same time is connected to the PC. Since the transformer needs alot of mAmps to charge and the computer cant provide that (not the normal Motherboards, u need a board with charge capability).
Both the TF and the docking station has this special door for connecting the USB cable.
I havent tried to connected yet the TF to the TV, so i cant comment on that.
Just as the title suggest has anyone successfully attached a HD 2.5 drive to the TF using a USB coupler to the tablet? I have a Seagate Go Flex 500 gb 2.5 drive but since the tablet itself has no usb port to attach the HD I would need a USB coupler to connect the cables, would the tablet's proprietary cable supply power and even recognize the HD using a coupler?
Please advise.
Edit: Nevermind me... misread.
I don't think it will work.
There is a thread in general you could search for with a list of usb devices people have tried to use without the dock.

Yeah, just checked out that thread, doesn't look like any HD connected with a coupler works, I am not sure about the dock but I remember some guy on utube was able to via the dock. I am planning to get the dock after 2 years when the batt on the tab wanes, no big deal, would have been nice having an HD attached without said dock.
I have had a project in mind for a few weeks now. I have been contemplating making a homemade HD dock for the Atrix 2. I know the dock is not that expensive, but I just can't justify buying one. Let me know what you guys think.
Enough positive response ill post pictures for it along the way/step by step.
EDIT: I forgot to mention but i will also try to add a powered usb hub so the phone will also be a Usb Host for External Storage, Mouse/Keyboards, and any other things we can think of.
EDIT#2: I have not abandoned you all, just ran into a busy patch with work and home life. Should anyone feel the need to give it a go by all means. Through my research it looks like the only way to create a fully working HD Dock is to modify another one designed for another Phone. I have found posts on the interwebs to suggest this. I dont believe the Webtop Will activate with just a Micro usb and Micro HDMI cable plugged in simultainously. ( Sorry for any typos )
That sounds great! Good luck with it. Please post pictures/instructions if you can.

In for results! I agree i can't justify buying a dock too.
I about broke down and purchased a dock the other day, but now am I glad I did not, good luck, and keep us posted!!
Good luck and please do post pics.

I was thinking about the same thing. I can't see spending the $ for a chunk of plastic with a micro usb connector in it.
It's simple to make a USB powered with OTG host capability.
Is it that what are you trying to do ?
With the hdmi cable/adaptor i think you get pretty close to a dock.

I don't have any docks so I can't experiment with Webtop... however if you can hardware-wise get a DIY HD dock then I'm sure we can figure out how to patch the necessary apks to get Webtop to activate.
cogeary If you go to this Thread it is an app that tricks your phone into thinking its been connected to something that enables WEBTOP or any other dock options for that matter.

Oh OK, thanks... so in that case it means that in order to get a fully functional HD dock you don't have to modify an official one for a different phone, correct?
No, not technically. I was doing this project just so no extra junk had to be installed as well as the option of adding usb ports to work with webtop .
From day 1 (purchased 10/11) a SD card or usb thumbdrive on the TF101 pad has not mounted. First thought it was the keyboard dock, sent it back for repair, Asus sent it back nothing could be found wrong with it. Bought a 2nd dock same issues, tried other pads on my keyboard docks, no issue with cards or thumbdrives mounting. Called Asus they had me send the pad back for repair, just received it today and they said it tested OK/No trouble found. I give up!
Sounds like u are doing something wrong? Or your devices are in wrong format? Check its docking correctly? A notification in taskbar should show. One will also appear once usb is connected. Click on notification to access.
Also try both usb ports.
Sent from my GT-I9100 using XDA App
I've tried every type of format, both usb ports, sd slot, several types of thubdrives, usb debugging in settings, power on while they are inserted. Only notification I get is when I insert a Micro SD in the tab itself. I'm done with it! Selling the dock to a friend that does have one (we know it works with his pad) and the pad to someone else that has no interest in the dock. This setup was going to relieve me from carrying a laptop around at work, I thought. Moving on. Thanks for your help.
So... You came to the Q and A section, which one would assume means you have a question and need an answer. However, it seems like you're stating a problem, and your own solution. Are we needed here?

hawkxcore,
I apologize for not posting this as a question. After 3 months of trials and failures I was a little frustrated while writing. Next time I’ll remember to add a “?” at the end of a sentence. Thank you for the written comment on my error.
As the title says, I want to charge my Nexus 9 while using a keyboard/mouse and other peripherals that I would have connected to the Nexus 9 through a USB hub. I know it is not always possible to charge through the hub, so I was thinking about something like a 'micro USB splitter" that expands the micro-USB port into 2 micro-USB ports: one for the charger that comes with the Nexus 9, and the second port for a OTG cable/usb hub/etc. Anyone have any thoughts on this?
I did read this post here for the Nexus 7 but not sure if the same is true for the Nexus 9.or if any additional options existed for the 9. Ultimately, I guess I'm wondering if it is unrealistic to expect to find something that charges the device at the same time as using a hub/OTG cable without too much modding or hassle? My device is rooted and I've flashed some mods and tweaked some things on previous devices I've had, but am by no means an expert so I would hope to keep the hacking/modding for something like this to a minimum, if possible. Plus, there's an outside chance I may return the Nexus 9 in the next week so I wouldn't want to get too crazy until I knew for sure I'd be keeping it.
I understand that a specific kernel with certain capabilities may be needed, but I'm unsure how to find out which kernel would work and if it would be compatible with stock ROM or CM12 (when it comes out). Any help would be greatly appreciated. Even if it's a pipe dream, I'd at least know not to continue to waste my time looking for a solution that doesn't exist
I tried this one a few days ago but it did not work: https://sites.google.com/site/sonicboomworld/my-projects/otg-and-charging
Maybe it's possible with the right resistor value.
Edit:
Mod for Nexus 7 - needs kernel support:
https://mehrvarz.github.io/usb-host-mode-power-management-nexus7/
Thanks for the reply - is this kernel still being supported by the dev and is it confirmed working on Nexus 9?
I don't know as i do not own a Nexus 7.
But even if he still supports this kernel it would not help much for the Nexus 9:
A kernel is very hardware specific and the OTG changing issues is even more hardware specific.
There is absolutely no chance that you can simply use the N7 kernel on the N9.
One of the amazing kernel developers (who owns a N9) here at XDA would have to look at it.
Generally I think for "OTG + charging" to work the USB chipset on the device has to support it and/or you have to find out how you could trick the device into enabling this mode (with a certain resistor on the USB connector and/or with a kernel modification).
The bad thing is that no device seems to support the official "USB Accessory Charger Adapter" specification. (see section "OTG micro plugs" here: https://en.wikipedia.org/wiki/USB_On-The-Go for details)
Just to give you more information, there was a nexus 7 kernel by flar2 called ElementalX which had OTG + charging support. He is working on ElementalX for Nexus 9 as well, and he said he may or may not add support for it. If you and maybe others are interested, I'm sure that it will get added upon request.

The company I work for is developing a OTG cable that does exactly that: lets you charge your phone/tablet while using a USB peripheral.
We are testing it in the UK market currently, but not selling in the US at the moment. You can check it out here: http://www.amazon.co.uk/Sansys-Char...F8&qid=1417298449&sr=8-1&keywords=usb+otg+mlc
We were thinking about doing a kickstarter or indiegogo for it, but not sure the amount of interest in a niche device like this.
Can you confirm that it is working on the Nexus 9? (and/or the Nexus 5)?
If it is, I'll order one immediately. I've been looking for such a thing since I had my Galaxy S2.

I can't confirm that it will work on the Nexus 9, but my partner from China is sending me a sample so I can try it out. I have a Nexus 9 and 5 also, and they'll be the first devices I will test it on.
We've also sent a couple out to some Youtube reviewers as well, so there may be a video review on them soon.
We just put up an Amazon US listing for this cable if any of you in the states want to try it out: http://www.amazon.com/dp/B00OLKFR44/
I should have one in hand in the middle of the week to test out.

This arrived from Amazon today. Unfortunately I can't get it to work. When the micro usb is plugged into the N9 it lights up blue. At that point I'm able to mount a thumb drive, use a mouse and Playstation controller. But once the other end is plugged into a charger the light goes off and whatever is connected stops working. The N9 begins to charge at that point. If plugged into my PC, same thing.
Note: the blue light goes off when other end is plugged in regardless of if anything else is in use.
BTW, running elementalX kernel and Lollipopalooza rom.

I've heard some people say in certain other situations with OTG + charge, you need to plug everything in first, then plug the OTG cable into the device. Try that and see if it works?

Thats a bummer, thanks for the info.
Would we happen to need a kernel that supports simultaneous charging and data transfer? I bought a usb y cable and that only allows me to use one or the other. Which sucks .
Some devices have been known to work with only modified OTG cables such as galaxy tablets and experia phones.
What would this modification be?
I finally got a chance to test out these cables. I thought my first cable was busted so I ordered a 2nd one.
I'm VERY sorry to report that this cable does NOT support USB OTG AND CHARGING AT THE SAME TIME. It is not just your device.
Apparently, there was some miscommunication between me and by business associate in China that lead me to believe that this cable would function this way but it only functions as a USB OTG OR CHARGER CABLE. Language barrier didn't help since I do not speak Chinese and he does not speak English very well. If you read the description, the functionality of this cable is not very clear and obviously written by someone with English as a second language. And also, I can see how the photos can be misleading as well. He went and listed this product on our Amazon account to sell before he even sent me a sample for me to test out and I'm kinda mad at him for doing that.
I was pretty excited at the prospect of it doing OTG and charging at the same time, but now im dismayed that this cable cannot do it. This whole thing was a waste of time to try to bring a product like this to the US that bares little benefit other than being a 2 in 1 cable that can replace a regular USB OTG cable and a Charging cable (albeit a very short charging cable). Sorry that I got your hopes up guys
I do want to clarify exactly what this cable does though: Basically all it does is switch from Charging mode to USB OTG mode depending on how you have it plugged in. If you plug the cable into the mobile device only, the blue light will turn on, letting you know that you can use the USB OTG port. However, once you plug the other end of the cable into a charger, the blue light will turn off, and the cable goes into charging mode. The USB OTG port will not work or light up again until you remove the cable from your charger.
hey there everyone, i'm trying to understand this a bit more. i have the same cable, but my understanding is that it wont work unless the kernel supports it. does anyone know if this is possible to actually fix in the Nexus 9 kernel? i really need this for a project
