USB charge? - Eee Pad Transformer Q&A, Help & Troubleshooting

What gives? I mean, they left out the microUSB port to use as a thumb drive. Then they made the end of their proprietary port USB, but I can't charge via USB. I just wish someone would get a clue and use 1 device jack. I would be okay with MiniUSB, MicroUSB, HDMI or the new HTC MHL. Just get something and stick with it.
Now, why won't this sucker charge over USB from my laptop? Why wouldn't my HTC USB plug charge the tablet? Anyone?

Not to be rude, and but there are already several threads regarding the charging requirements of the tablet. You should browse around a bit and do a forum search. I promise you will find the information you are looking for in an existing thread.

I did. I read that you should be able to charge if you have a USB3.0 port. I have a loaded ASUS RoG laptop, it definitely has one. It was in the updates thread. If I have misunderstood then my apologies.

Not sure if this helps but if I plug the USB cable into the tablet while it's on it does not charge the device. If I turn the tablet off it does charge from the PC connection. I guess it would be nice to have everything be micro USB but I think they needed something a little beefier for the dock connection so they just went with it.

Correct. The device would always trickle charge when connected to a pc and not in use. I am assuming the 3.1 release notes just mean it will just trickle charge faster and connected to a pc when not in use.

No, it does not show when it's trickle charging, and yes it will trickle charge on usb 2.0. Slow as he'll, but it will pick up a charge.

I wasn't exactly scientific about it but I left the tablet in its normal sleep state overnight plugged into USB 2.0 on my pc and the battery looked about the same as I left it in the morning. Did the same thing the next night but powered off before bed and the thing was all charged up. I suspect the trickle charge would be more obvious when sleeping if it wasn't for the fact that the tablet seems to be in a higher state of sleep so it can stay accessible to the PC (i.e. I can drag and drop a file to it six hours after I plugged it in and it's just ready to take it).

[Q] EEE Pad ONLY for android development

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.

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

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.

[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.
[Q] USB OTG?
That's pretty cool, keep up the work.
Does anyone have ubuntu chrooted to check if the usb module is reporting anything?
kinda pre emptively ordered one in hope.

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 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.

Genuine ASUS Connect Dock

I just took delivery of the new ASUS Connect Dock, purchased from Amazon.de for €75.15.
I also own the keyboard dock but find the latching system a bit awkward for everyday use as a desktop top docking/charging system. I'd been looking for something like this for a while. It had already been discussed in another thread and on a chance I placed the order. At the time it said that delivery would be in 4-6 weeks. I was quite surprised when I got a message to say that the item I had always thought of as "vapour-ware", was set for delivery on the 17th of October. Well, it's the 16th today and I'm happy to say it's here.
As you can see from the pictures below it's quite small but fits the tablet perfectly without any real drag on the plug being felt either when docking or undocking.
When I first docked I had the LAN cable and power cables plugged in and the TF700 immediately recognised the dock, connectd to the LAN via DHCP and proceeded to charge. I found that the notification bar now had a few new icons, one of which was for the LAN. Tapping this icon brought up a settings page which gave me the option to use a DHCP or Static IP connection. Once I had configured a static IP I had a button which said CONNECT appear, which when touched connected with the new parameters. All was well. :good:
I next tried to connect one of the two USB ports to my PC to see if it would be recognised but obviously they are OTG and cannot be used for a data connection for transfer of files from the PC - no fastboot or ADB. Connecting a USB memory key needed the use of the mount option under Settings-Storage before it would connect. The same was true for when I tried my 1Tb HardDisk. Once mounted both worked as expected. I imagine that connecting a mouse and keyboard would be a no brainer. I can't verify this or that a wireless setup would work.
It is rather expensive for what it is and has a few shortcomings - no HDMI port, no USB data pass-through - but it does do its intended job well. There is a supposed amplified audio-out port but I have not tried this yet. I have no idea whether it is connected internally via USB or directly to the headphone socket. Maybe someone in the future may open one up and check out the internals so we can know more.
Typically I like accessories and this adds to the kit nicely.
Cheers,
Eric
EDIT: I tried the USB HardDisk again and this time it was recognised immediately and opened Filemanager. I was able to watch a movie directly from the drive which I guess means that the USB ports are also powered. I'm even happier now!

i can't see your pictures - and very much would like to! i'm seeing a section for thumbnails on your post, but no actual thumbnails in it
UPDATE: reloaded the page a bunch of times and the pics showed up - thanks for sharing! it's WAY smaller than i thought it would be. smells like a perfect thing to use on your bed table to turn your 700 into a clock replacement overnight (gotta keep these geek tech assets working 24x7!!!!!). seems pricey for what you get, but i think i'll grab one when they hit the states.

I haven't tried it but I'd say it would since the power input is the standard 40pin plug and that's what's on the car charger as well.
I know for certain that the tablet charges on 12V because I modified a cable from a car charger - the circuit inside contained a 12V regulator - onto a Kensington netbook charger. The only critical bit is the need to be able to provide at least 1.5A, preferably 2.0A.
I don't have the means to test it so you'll just have to believe me or wait until someone else can.
Gotcha, thanks for the reply. I wonder if the USB ports work with a hub, that could be interesting.
If only I could find a US vendor then I could try these ideas out myself.
it'll work but it wont say its charging and will take forever to gain any charge

Asus drives me nuts!
http://www.asus.com/Peripherals_Accessories/Eee_Pad_Accessories/Connect_Dock/#overview
Above is the link for the dock, yet these Asus people offer no info on how to actually obtain the frigging thing.
There's got to be a factory somewhere in Taipei that's stamping these things out by the pallet loads every hour.
I hate this "dangle a neat-o accessory over a pond full of hungry fish" attitude then let 'em starve!
Damn them!
Network
I have a USB Ethernet. Assuming dock Ethernet works the same......
The tablet connects to the LAN on which the Ethernet exists
Using a file explorer (I use ES File Explorer) I can log onto the LAN via the Ethernet (also works via WiFi).
So long as the required shares are set up back at the PC, there is no problem accessing, copying, deleting etc.
I have even played movies which exist on my media server on The LAN, via WiFi, and watched them on the tablet. Not totally smooth but easily watchable as I fall asleep in bed!
Simples!
Regards to all
Ian Wilson
And, forgot to mention.... I have a USB HD which connects fine through the USB on the keyboard dock - power and data - no problem.

You can use Google Cloud Print to print wirelessly from the Tablet. If your printer supports Cloud Print directly (not that many do) you can set this up very easily, and no PC connection is required - only an internet connection for the printer. If your printer doesn't support it directly, you can still set it up and print to it, but it requires your PC to be on and connected (cable or WiFi) to the printer.
This is actually a pretty slick option - works from my Samsung Galaxy Nexus and probably most other Android phones.
If anyone has any info on a US release date, I would appreciate it. Calling ASUS did not help because they weren't even aware of this dock. They kept insisting I was referring to the keyboard dock.
Maybe Asus will bring the Connect Dock to the US for the holidays. I would really prefer one of these next to my bed than the tab in its keyboard dock!
Come On Asus!!!

Does the TF700 have the ability to route HDMI through the dock connector? I mean is the wiring in place, I ask because it would seem that they would have forgone a dedicated port if so and used a modified MHL connection?

Having looked at the threads which discuss the pinout configuration for the 40pin connector I can say that it doesn't like there are any connections to HDMI available. There is no passthrough for HDMI on this dock and since it doesn't look like the connector has the pins that it would be pretty sure that it's not possible.

Makeshift USB/HDMI "Dock"...?

I want to take advantage of the S5 MHL capability. Perhaps eventually using the phone as my everyday computer.
So I would need to have usb keyboard and mouse while connected to a monitor.
I have ordered the device pictured below, it reportedly supports the S5 in some kind of half-assed way, meaning that you may have to fiddle with inserting cables in a certain order to get it to work.
This is what I read anyway.
I want to know if any of you have used the Galaxy S5 in such a way. Will my device work? Know of a better solution?
I had some dreams of making my own Diy S5 dock, but I would have to know what kind of electronic/hardware configuration works (if any), as the S5 is different in that it does not support dock mode (Why samsung... why?).
Well I can report that it works. HDMI out works with sound, and it charges while doing so, but the USB port and the card reader does not work apparently.
Obviously the form of the device is a poor match for the Galaxy S5. I had to remove the plastic housing to make it fit, because of the watertight hatch in front of the USB port. Later I will use a USB extender cable.
Hopefully there is a possibility to make OTG (or host mode, or whatever it's called) work.
It appears this device supports the S5
http://andromiumos.freeforums.net/thread/4/officially-supported-android-phones?page=1&scrollTo=4
http://www.andromiumos.com/
There is two question marks here.
1) Does S5 support simultaneously operation with OTG active and HDMI output active.
2) Does this gadget also support such a functionality?
I don't know. I've read people claiming that you can use both hdmi & otg at the same time including post's on xda. But i've also read people saying you can't. I certainly havn't seen any video demonstrations.
By the way i currently have my S5 displayed on my monitor using mhl->hdmi adapter and have my pc mouse and keyboard working on the S5 wirelessly with Samsung SideSync. I opened the xda app with the pc mouse and have typed this reply with the pc keyboard. I've done some navigation on the phone, opened and used a range of apps. All is well till i opened firefox and the mouse disappeared from the monitor. It's still displayed and functional on the S5 screen though. Closed firefox and the mouse is displayed on the monitor again.

Therefore your new question this is : Does Firefox (Android) this supports four input devices connected at the same time?
Android Keyboard = 1
External keyboard = 2
Android touch pad = 3
external mouse = 4
And all that active by also active HDMI
I would be surprised if Android OS has such potentials.
I was using Andromium OS app which gives you option to turn off android keyboard and dim S5 screen. Both those functions worked. Andromium OS has 3 menus from start menu. Andromium Apps(browser, file manager), Supported Apps (gmail, youtube), Unsupported apps (all other apps installed on device). PC mouse and keyboard worked fine with Andromium Apps & Supported App. PC mouse and keyboard also worked fine with most unsupported apps i tested except firefox browser and adblock browser. If i get my hands on a bluetooth mouse/keyboard i'll test again to see if it works with firefox browser and adblock browser from monitor.
Personally I am going to use my HP iPAQ FA287 Bluetooth keyboard at S5 ( or at least I will try).
Also ordered one OTG cable (CY U2-166) that hopefully this will offer power to the phone and External HDD, due micro USB (female input for charger cable) and this will become also my mouse input too.
Therefore I am interested for your inquiry / investigation, possibly as much you do, because I do also favor Firefox.
I favour android firefox browser and adblock browser because they are consistent in providing desktop view. I'll provide an update here when i get my hands on a bluetooth mouse & keyboard.

My cable did not arrive yet from China.
But even so, in the past days I did some research about finding more details by discovering the factory that makes those cables.
According to real Specifications: (after me correcting errors due bad translation)
High quality Original USB 2.0 Micro-B HOST OTG CABLE
Interface:
Micro USB male: = Output To be connected with OTG complying device ( Your phone or tablet).
Micro USB female: = DC input To charge = Supply of Power due micro USB female connector ( This is only to supply DC voltage to USB A plug this powering hard drives etc etc).
USB female: To connect with USB A device.
Therefore or in conclusion, this cable is not in position to supply power for the phone and the external hard drive.
Later on, that I did the electrical math, I can now explain and the why ? (this cable cannot do both).
By assuming that mobile phone or tablet this requiring 450mA at charging (due PC USB plug), and removable hard-drives (some of them requiring another stable supply of 500mA) the sum this is almost 1A of power.
Manufacturing of OTG cables this requiring from the manufacturer, him to make a product according to OTG cable international standards (compatibility - safety - functionality).
Only if Samsung makes a OTG cable specifically for S5, this will be able for active Host and charging.
All cables available at the moment, them have generic compatibility and non of them will work as we expect or wish.

By assuming that mobile phone or tablet this requiring 450mA at charging (due PC USB plug), and removable hard-drives (some of them requiring another stable supply of 500mA) the sum this is almost 1A of power.
Manufacturing of OTG cables this requiring from the manufacturer, him to make a product according to OTG cable international standards (compatibility - safety - functionality).
Only if Samsung makes a OTG cable specifically for S5, this will be able for active Host and charging.
All cables available at the moment, them have generic compatibility and non of them will work as we expect or wish.

Samsung hasn't made it easy for us S5 users. Might have to resort to wireless charging at this rate.

Just going to throw this out there...
Why not use a bluetooth mouse/keyboard (or even one of those combined ones) with the phone mirroring it's screen to a ChromeCast plugged into your monitor? There's minimal (and I mean you're looking at 10ms) lag - or that's my experience, but I have a really really really fast router etc - and if you're planning on using it essentially as a PC, this setup will work wonders. Plus you can plug the phone in. I've considered using my old S3 in this way.

Charging the S5 through 2A cable would be faster than wireless charging. MHL to HDMI adapter charges the phone as well as mirror your phones screen. I've never used bluetooth mouse and keyboard. Would the S5 support pairing and using both mouse and keyboard at the same time?
By the way there are products for the S3,S4 that support mhl, otg & charging at the same time like the UNITEK Y-2165.

Speaking of compatibility, S5 this is a brother model to Note III.
I do such an assumption due the identical charging system specifications.
From the other hand with all those variants of G900, there is no chance to offer an 100% reliable prediction if you do not test any such OTG product with your own phone.
The link above this is about a Currently unavailable product.
Even so it is interesting that this worked for someone with Note III.

The S5 (or certainly my model, G900T) DOES support everything I mentioned however my bluetooth mouse/keyboard is a 2 in 1 setup with the mouse being a trackpad below the keyboard, similar to a laptop. It mirrors directly to my monitor and I've forced Landscape orientation throughout the OS so it works wonderfully. I've not tried yet with the S3, but I'd assume it'd work the same way. Just need to force the screen to stay always on, pop the screen brightness right down and hide it away in a cupboard and boom, full android computer.
On the original question, a cable must exist but unfortuantely I don't know where.

Definable this is a bad idea the screen to stay always on.
Does phone screen brightness this have any effect at HDMI output (brightness) ?
Nope, but turning it off does. I don't mind it burning out as it's an old device I don't use.

I bet 20 Euros that every one reading this topic he/her, will wonder of why you/he, does not simply turn the brightness down.
Either way, Android it is crippled operating system with out offering much of productivity as it does one regular Windows PC.
Neither a smartphone this is capable for long term gaming, the poor thing does not even have active cooling, and CPU will start slowdown so to protect it self from overheat.
My 0,2 cents, you are in a wrong path.

The link i gave has a few reviews that can give you an idea of what phones are compatible and which ones arn't. Youtube has video demos of the UNITEK Y-2165, unfortunately none for the S5. It appears the desktop dock feature is on the Note III where as samsung removed the dock feature from the S5.

oh ok, so only 1 device paired.
There's a great app for having screen brightness right down called Screen Standby.

I tell you what, i really like the concept of carring you desktop in your pocket. Can you imagine that, doing your desktop stuff, unplug the phone and head out with everything you did at home on the desktop in your pocket. I know microsoft have a desktop adapter for their Lumia 950 XL phones which changes the layout to desktop mode on the monitor/tv to give you that PC-like experience.

It's a real shame samsung removed dock support from the S5.

OTG and recharging shield tablet at the same time possible???

Anybody knows if its possible to connect usb OTG host and charge the tablet at the same time, i found out a way to enable adoptable storage on USB drives so im planning to offload my console games(borderlands, half-life,etc) to an external hard drive cause i only play them at home when im in console mode, and if it is possible anybody knows where to get one from a reliable seller?
Haha just bought an adapter on amazon.

Does it work charge and enable usb host at the same time? The current one i have acts weird, if i leave tablet alone, usb plugged in host mode as adopted storage my k1 charges, but if i start using it, even on light usage, battery discharges even if it indicates it is charging
Haven't tried it yet. I'll let you know ASAP when I've tested it.

USB OTG and Y cables?
Sent from my SHIELD Tablet K1 using Tapatalk
Okay, they one I've got is damaged. Gotta send it back.
The ones Exile suggested I've one of them. Though, they connect all to big female USB! So you'd need another USB cable (Big male USB to micro male USB for the tab).
I've been using this one, and it works pretty well for charging and using OTG at the same time. But it won't recognize USB devices unless the charger is plugged in, probably because it has a built-in hub.

Thank you for the replies and suggestions, looks like the one im gettting is the same one by @primaleph
Y OTG cables do NOT work with the Shield. I tested a bunch and it's either charging or gamepad but never both simultaneously.

Well actually they do, very2 slow, i hooked the OTG i bought to my charger, my tablet and my printer, then started doing some typing work while listening to some tracks on spotify max volume and at about 20% brightness,, after i finished and checked my battery it went up from 95 to 97, also tried the same with a usb attached, so for light loads it does charge but for gaming, even i lose charge when playing games such as vain glory while the tablet is directly charging so im sure its still gonna drain but probably not as fast as not charging at all, or another thing is not all OTG Y cables are configured the same me and @primaleph just got lucky with the ones we got and yours are probably the not compatible ones
A printer?
Anyhow, it doesn't show the lightning symbol if two devices like charger and gamepad are simultaneously connected. Whereas, using just one of the devices works.

Yeah i use an app called printershare, it allows me to use printers directly via usb connection cause i still own those old printers with no wifi connection costs 10 bucks for the license though, i tried with my old usb gamepad and it also charges and gamepad works, i think you need a more powerful charger, i use a tronsmart quickcharge 3.0 with a 2nd port with a max of 6.5V 3amp output which i use to charge it in OTG mode, 5V 2amp chargers should work but sometimes the power cuts out on The devices being connected, happened to me while on a boat trip, boring 2hr ride, me and GF wanted to listen to some music but we both own over the ear headphones not those little earphones, i charge my shield with a powerbank that provides 5V 2A output, plug it in the OTG and use a usb soundcard with with two audio jacks so we both could listen and throughout the trip there are times the soundcard would lose power which was pretty annoying,
Heres a screen recording where it is charging and i attach devices one by one to my shield tablet

i bought this one , it work not enough quick and don t know if i did well,
i use mode 1 , plug hdd then plug charge, in video they use mode 2
