Has anyone gotten an OTG cable to work with a micro-micro-USB extension cable? Every combination of extension cable and OTG cable kills the OTG functionality (but still allows power).
I figure the extension cables are just straight-through wires. No idea why it would kill the data lines.
I'm using a Y OTG+charge cable for a car install. The micro-USB end is a straight plug. I'm using a micro-USB extension to provide a right angle plug to the tablet. I can't find a Y-cable with a right angle plug.
I would try to figure it out with a multi-meter, but have you tried to get a probe in the end of a micro-USB plug?

I remember reading somewhere that USB otg and charging only works if you plug the splitter and power into the tablet first, followed by the other attachment (wifi, storage, keyboard, etc.)

USB OTG and Y cables?
Sent from my SHIELD Tablet K1 using Tapatalk
The OTG Y splitter works just fine by itself for OTG, sync, charge, etc. Yes, I know how to use the OTG cable.
My issue is, when I plug an extension to the OTG cable, the OTG function doesn't work. Assuming the extension is just a pass-through, there's no reason why this should happen. And I've tried multiple OTG cables and multiple extension cables.
Nope, it's well known that extension cables don't work, even for normal usb cables - loss of signal or power over distance I do not know, but it's a sad occurrence. I've got a 5m microusb cable that doesn't charge at all, which I can only attribute to it's length.
I'm not saying that it always fails to work, but if you've tried several cables it's safe to assume that the extension cable just isn't workable in this case.
After some surgery, I figured it out. It has nothing to do with signal/power loss. To save costs the extension cables don't wire the ID pins (#4), which is needed to signal OTG status.
That being said, all that a Y cable does is provide external power to the VCC/gnd wires. Easy enough to turn a right angled OTG cable into a Y cable. I'm just out $10 for my experimentation.

I was wondering if there is any such device / cord which would convert the Asus proprietary plug on the transformer to a USB cord or something so I could plug in different things without having to buy the keyboard....
Yes it does exist:http://www.asus.com/Peripherals_Accessories/Eee_Pad_Accessories/External_USB_Adapter/
Could you charge the tablet with a regular USB cable using that adapter?
Only when in deep sleep or turned off - but it charges.

No because the USB adapter linked only outputs 5v on the USB port, its not an input.
The USB socket is the wrong type for normal USB cables used for charging, but even a USB-A to USB-A adapter wont allow charging and may even destroy the USB adapter (well, it might not, but I certanly wouldnt want to try it!)
That is sort of what i was afraid of. I was hoping that since I can use the propietary cable, I would be able to switch to a longer cable with the help of the adapter.

Just attach an usb3.0 cable to the propietary cable. Then you have a longer cable.
I'am using this with the tablet and charger.
It has to be USB 3.0 cable? Dang, I actually do have an older extension cable somewhere (forgot all about it until I read your post) but it is pre-3.0, but hey, if i find it I will at least give it a try, not like something would brake, right? Right??
hmm...I had asked this in my thread, but no one has given me a straight answer. Looks like it wouldn't work even with Male A to Male A. I already bought one, so maybe I'll give it a try. Has anyone done so before?

Yes, it must be a usb 3.0 cable.
I have this one and can charge the tablet with this cable attached to the propietary cable and the asus charger
Just tried it again and it is now charging.
That is cool, but I was hoping it would be in a "cord" form because imagine you would have that sticking out from your device, then on top of that you would have your usb plug sticking out as well...
Also, would this work with something like a wireless keyboard and mouse? (the wireless receiver is USB)...
Hey everyone.
I had an idea for a hardware hack.
Seeing as there are a lot of devices that you cannot use a usb otg cable alone to connect a flash drive (hp touchpad being one of them)..
My idea is a cable/battery hack. using a micro-usb-usbA cable and a portable usb charger i am curious if there is a way to splice the battery in-line with the cable.
Such as micro-usb to USB-A modifying the battery charger to put another usb Male end on the other side so that you can just plug your flash drive into the one end and the male end into the otg cable.. kind of eliminating the entire y-cable/second cable spaghetti situation.
i'm just brainstorming a few ideas to kind of simplify the carry-on mess of cables some of us handle.
Is this a valid idea? or am i asking for nightmares with the wiring/backfeeding power/etc???
Hello, we all know that there are USB OTG Cables with extra power plug (Y cable) but those are supposed to power external device like HDD, DVD, or anything what consumes more power than our android device can handle.
But my question is: is there any USB OTG cable with additional power plug but for simultaneous tablet / phone charging while USB stick is used?
I want to watch something long (i.e. TV Show series) from USB stick via OTG cable but I cannot simultaneously charge my tablet, so if it take too long my tablet will be out of power before I stop watching.

That means I have to add a resistor only to usb connector or just need a different kernel, or both?
On the native firmware say that this support function is disabled. Personally, I use this CivZ-FLEX-ЛУЧ-REV3.6.2 + SphereXtreme, where works flawlessly with OTG + charging resistor 64.9 K.
I call BS!!!!
I have a stock firmware, and have been using all kinds of USB cables. Found the best are made from Sony/Ericson and Blackberry. Once you have a quality cable your charging issues will go away.
Right now I am using a 7 foot cable that is from a Sony. No charging issues and works perfectly.
Lately I found another MHL cable 2hich is called HDMI to Micro HDMI, and that micro HDMI plug looks exactly like micro USB. Will such cable work with Note 8 properly without additional power?
The version of MHL our device supports requires a power source external to the tablet. That means the adapter itself needs to provide the power (battery or power adapter) or can pull enough off the HDMI cable, which is usually not enough juice to run the connection.
MicroHDMI and MicroUSB are also not physically compatible (won't fit the same port and different pin outs) even if they look so much a like. MHL typically uses MicroUSB at one end and full sized HDMI at the other.

This is correct u need to put a 63-65 k resistor between ground and Id pin(pin 4 &5) on USB connector. Doesn't work on civatos 4.4.2 as of now. USB host works fine with regular USB host cable but no charging when u use a y cable. I use civatos 4.2.2 kernel also. Works on yyks note 2 4.3 port also..
I have test multiple times. I use a USB dac in car and need charging and USB host.
what resistor should i use on my sghi257m samsung galaxy s4 mini otg usb cable?
on my dads galaxy s5 Active it shows message that says: Do you wanna enable power sharing
is that OTG? on my S4mini nothing pops up
I know this thread is really old but i want to use a USB DAC so need at cable with a resistor as mentioned above but What ROM should I use now?? also is there anywhere I can buy a cable with resistor in it or do i have to do it myself?
Hi
I have a problem with my new S5.
For my S3 i created a USB OTG+Charge cable. For this cable type a 68k resistor is soldered between the sense and GND pins of the USB port.
this cable is not recognized by the S5. When I keep the resistor open the charger is recognized.
When I short the resistor the USB harddisk is recognized.
I tried a resistor E6 decade to test variuos values. When I use 100k the cable is recognized as "power sharing cable".
Is anybody here using a USB OTG + Charge cable?
Where is the cable detection definied? Can I change it?
Best regards,
any progress ?
For my new S5 I have ordered one CY U2-166 cable.
Sellers listings talking about compatibility up to S4, and read even one user feedback that this worked for him.
When my cable arrives (eBay) I will test it, and if it works with S5, then I will post actual measurements regarding cable construction.

You are welcome, but be aware that this cable comes with dual micro USB, plus one Female USB A for regular connectivity and powering external HDD.
Female USB A this is output.
Input power comes from your charger cable ( Mini USB connector).
Here are my experiences with OTG CY U2-166 cable.
1) My Galaxy S5 this is fully capable to deliver enough electrical power for USB stick, or even my external USB 2.0 HDD (WD 160GB)
2) External USB HDD this causing a minimum of 220mA of consumption up to 430mA at extreme activity.
3) When female micro USB this is also powered by external source (charging block), this become right away the main DC power source for the external HDD.
4) If incoming DC power from female micro USB this no more active? Then Galaxy S5 takes over right away by delivering power by it self.
In summary this additional female micro USB, this works in parallel with DC output of the phone.
Personally I am very happy from those results from a cable worth less than 2$.
But what caused me mixed feelings this is Android it self, this does not recognize several partitions over a single hard disk, even if them are formatted at 32GB/Fat 32.
Hello, I've bought this phone 1 week ago and it works really nice.
Some things I really don't like, like the chinese ROM (which I'm waiting for the unlock to switch to global) and the fact that we don't have the 3.5mm headphone jack.
I know that the phone comes with one adapter, but it might get damaged in the long run (the cable is not sturdy enough). I tried an USB 2.0 sound card connected to the phone using a USB C to USB 3.0 OTG adapter, but by doing that, the wireless charging stops.
In fact, anything that I plug in the OTG cable will stop the wireless charging.
So, I want to know if those cheap USB C audio sound cards will behave like the official USB C adapter, or they will stop the wireless charger.
Also, are those USB C passtrhu cables with a sound card working in this phone? Because with that, I could plug a wall charger and also get the headphones.
BTW, I know I could use BT, but thats not my idea.
Any feedback will be appreciated,
Thanks!
I think those audio jack/usb c cables should work.
The phone probably stops the wireless charging because the phone cant supply and get charged at the same time.
By using those cables you use the data pins for audio and the power pins for charging so it should work.
If you want to test this theory out use the original usb dongle and put it on the wireless charger.
The official headphone adapter is analog without a dac so it is not a usb device as such. It must use a dac already in the phone. Wireless charging works fine with it. I can confirm the plugging in a usb card reader stops wireless charging though.
