Alright. I exhausted both Google and the forum search trying to find an answer for this but so far have come up with nothing.
When you plug in a flash drive via OTG, a popup appears in the notification bar explaining that the phone is in USB host mode and unable to charge. I have confirmed this by trying to use an OTG Y adapter and, even with nothing plugged into the female USB, the same notification is present and no charging light appears.
My question is whether or not it is possible to fix this with some sort of kernel patch or if this is some kind of hardware limitation. My HTC Evo 3D was able to charge while hosting a flash drive with an OTG Y when using stick mount while my Nexus 7 required a kernel patch to be able to do so.
Is this doable on the HTC One? I plan on using a USB stick for playing games rather than filling the internal storage but being unable to charge simultaneously really limits the play time if this is the case.
Thanks for the help and hopefully my searches didn't miss some obvious answer to this.
Ya know...I saw something via kernal or rom when I had the HTC One for AT&T. I never activated it during setup though. It dealt purely with the USB/computer charge and was some type of override.
I know this is vague and it is probably not available yet for the Verizon version, but I wanted to say that something was out there so I believe it is possible.
Update: It was the Bulletproof kernal. The feature was force USB fastcharge. Not sure if this is exactly what you were looking for, but I believe it tricks your phone into pulling as much power as it does when hooked to AC. People say their pc now charges their phone as fast as wall charger.

Which ROM are you using?
Check settings/connections/USB to PC and make sure to check the box for "enable charging over USB"
I need to clarify more for my dash's problem.
When I use the wall charger my Dash could not be charged, samething with USB connect to PC. But sync to PC I have no problem at all.
my ROM version is 1.11.531.1
Cheap workaround

Try changing your rom or if that fails you could order the Dash Dock for PC with the extra battery charger. THis is a cheap workaround if your dash is not still under warranty. I saw a dash dock w/ battery and a car charger for 18$ the other day on AMAZON

go to the last panel "settings" scroll left or right till you see, "USB to PC" click on it and remove the first check mark.
plug your phone back into the usb cord.
If I unmark that noway it will be connected to USB port. I did try and no luck
Did you try a new battery?
It seems from most of your past posts you are full of bad luck with phones. If you replaced your LCD screen recently, then you might want to be sure you installed it and all other functioning parts correctly. I believe there is a youtube post floating around that tells you exactly how that should be done.
That might be a reason it's not charging but any feedback helps right?
I agree with the above. As an electrically minded individual, I must say, that you either don't have something connected correctly, OR you are grounding out your system and there is no way to charge this. If you have grounded out your system. Check your internal electrical connections. This is what I do for a living. TRUST ME
Would you give me more details how
I read all of your posts and it appeared that I am at fault for fixing my own phone. Either I have a bad luck or I don't have enough skills to fix my Dash, at least I tried my best and also that the reason I came here for help. Please either help, advise, suggest but if you offer no help just be quiet instead of telling me that I am stupid. I may not know much about the phone likes the last 2 guys but I am willing to learn from your guys.
Anyone else having this problem. When I have my TMOUS TP2 hooked up to USB I keep getting told it's not getting enough power to charge.
Interesting. Is the USB plugged into a USB hub or straight into a computer? I can charge mine via USB when its straight into the computer. I'll try with hub a second to see if there is a difference.
Edit-
No, I cant. When plugged into a 4-port USB hub, I also cannot charge. I'm using some generic nonsense hub, dunno if a higher quality one (or one that also plugs into the wall for juice) might make a difference
Yes!
Many laptops are not powerful enough to charge the TP2. Also many hubs will divide the power between the ports.
A standard USB port will give you about 1A and the above mentioned gives you typically less than 1/2A.
Putting TP2 in standby will help if on a weak port, but that makes no sense, cause then you can use the charger.
It's directly in to my PC.. weird.
I got the "not enough power" USB warning when plugged into my laptop...but not right away -- it had been plugged in for 30-60 minutes or so.
I have not received that warning when plugged into the USB port of a full-power-desktop PC, even when plugged in for hours.
I try to remember to bring the ac adapter that came with my TP2 when I'm going to be away from home for a while so I don't have to depend on USB-power from a computer.
I charged off a 0.5A power source (the most you'll get out of a standard USB port), but the device was turned off. Took about 3.5 hours to fully charge it.
Did you have anything like wifi, gps, etc turned on at the time?
how much power is left on the phone? IIRC, if its too low, your phone will not charge through USB & you need the AC adapter.
There are "powered" and "unpowered" USB ports. The "unpowered" ones just basically carry enough current to carry signals, but not actually power a device. The "powered" ones carry enough current to charge a device.
Many laptops are "unpowered" ports, although I think that trend is changing. Most desktops I would assume are "powered".
I personally only power my phone on one of two official chargers I have, although if I'm in the car I'll use a third party adaptor there.
I don't know if the TP2 is any different than the Tilt in regards to charging, but I'd assume very similar.... Perhaps I'll have the TP2 soon, I've finally gotten ATT to let me have an early upgrade but haven't found the actual phone yet.
I have a 5v 1A car charger. When in the car if I am using Pocket Player, and my GPS program at the same time I will get the message that:
"there is not enough current to properly charge the device. Please should shut down unneeded programs." or something like that...
And sure enough, my phone will die if left like this. It won't charge, even though it shows that it is... curious.
Could it be the cable is not allowing enough current? I am using an older cable in the car, as I have my TP2 supplied cable on my computer....I am going to try swapping these 2 cables tomorrow and see what happens.
I've had my Sprint TP2 for 12 days now and experienced this problem once. I was plugged directly to my PC via the USB port. I believe my battery was at about 30% so I disconnected it and used the travel charger for awhile and plugged it back into the PC USB port. So far that's the only time it's happened.
Might be the cable!

Hello,
I had exactly the same problem and found out it WAS the USB cable - the one used couldn't offer more than 300mA to the phone, even if connected to orriginal HTC AC adapter. After changing the cable, the 1A car charger gives the same mA as the AC adapter (checked with nuePower - http://www.nuerom.com/BlogEngine/page/nuePowernueBattery.aspx)

Thanks for the info.. I haven't driven anywhere since I posted that! I will be in the next day or so... glad to know the answer is simple.
I too, just downloaded the NuePower program. Will be installing this as well. Did you by chance have the chainfire 1% battery cab installed? If so, did you unistall it first? Wondering if there will be a conflict between the 2.

Hi,
Yes, I have chainfire's cab, I didn't uninstall it before installing NuePower (btw, I have tried once to uninstall it and after a soft reset, the 1% info was still there). the only bug I saw was when pressing the OK button in NuePower - sometimes phone hungs or runs very very slowly. Best is to use it only to test the cables and uninstall it. and don't press OK button, just minimize it with End Key or do a soft reset if handy.
Mine does the same thing lol
I get the same thing, i think they should make these devices use even more power.
Don't know if will help, but last night I was in my car using Live Search for GPS purposes. The battery was low on the phone, so I plugged it in. The phone told me that the source was not strong enough to charge the phone and to try shutting down some apps. I assumed that it was because the GPS was still active, although I really don't know because I didn't bother testing that theory, as I was just around the corner from my house. (No jokes about using the GPS to get home, please. )
Anyway, when I got home, I plugged into my laptop (which was running on AC power) using the cable that came with my XV6800. Note that the cable is always connected to my laptop via a cheap USB hub. I experienced no problems.
So, my nephews fire had the USB come loose from the motherboard which required me to reattach it. I got it re-soldered but it won't charge. It does however connect to my PC (had to transfer a rom to it to unbrick it, long story) I feel confident that all the pins are making contact, the only thing that may have happened is the small chip that connects to pin 4 may have gotten overheated. would that cause this issue? if so does anyone know what kind of chip that is? it looks like a resistor but i can't tell what value.
Update: I was able to get it to take some charge through my PC's USB. have not since been able to replicate it though. I am beginning to think one of my connections may not have held.
Ok, it charges on the wall charger now as long as it is not in sleep mode. it will also charge on the PC if it is in sleep mode. My computer also cannot seem to load drivers to access the internal storage. Do i need special drivers for ICS?
This may be a dumb question, but since ics doesnt properly indicate when charging is occurring, could it just be that you didnt leave it long enough? You may want to test it on stock instead...
Sent from my DROID BIONIC using XDA
I might try that. I have been having a hard time getting to consistently charge. sometimes it will start charging for a second or two then stop, or it will not start at all. currently it is in sleep mode attached via USB to my PC and the amber light is on.
Can anyone tell me if it's possible to use wireless charge while OTG mounting external storage?
Need something like this to replace my current car dashboard tablet.

No, it is not possible at least in its stock configuration with stock rom. I tested this last night with my Xbox360 controller and my koolpad qi charger. As soon as the OTG cable is inserted, wireless charging ceases.
I'm assuming there's a good reason why it functions like this.

Ah ok, thanks for the answer even though it wasn't what i hoped for
I guess it needs a kernel hack to so for, and it disable charging for security reasons since OTG host is also power supply.
Guess Nexus might not be what i'm looking for unless i use some wireless storage solution.
On my nexus 4 when I connect it to my TV using a slimport cable to HDMI, I can still place it on my wireless charging orb and it chargers wirelessly.. Weird that the n7 doesn't follow the same behavior... I am going to test it to make sure...

I'm not sure how the SlimPort/HDMI works, but i think the difference is that the phone act as power supply when you use OTG. I looked at the kernel for Samsung Galaxy Tab 2 and Nexus 7 a long time ago, and could see the source switched the power from "pull" to "push" when OTG was connected, and could be possible to hack the kernel, but i never dared to try because of the risk there might be doing so. I'm far from an expert when it comes to stuff like that, so better not to mess around too much
Anyway, i hoped there might have been a chance with wireless charge, since it's different "connector", so maybe the kernel wouldn't turn off charge when OTG connected, but seems like it does.

That would be my guess too, whenever the USB port gives or receives power (or thinks it's doing either), wireless charging is turned off, probably to prevent overvoltage or short circuiting the battery.
Qi charger most likey can't give enough current to the device while it has a USB otg attached.
any update on this question? same behavior for me with @bruce2728 rom and with Glitch kernel. can't seem to find a way to use USB otg + charging....

Then you have not found this thread yet
That's basically it. Hard to find an answer in Google on this one. I have this y cable that has the female micro usb for power connected to the female usb connector as if it's for powering the usb device, not the phone, tho I've read reviews on the cable by people claiming it charges the phone, but some phones need some mystery kernal I never quite found. I'm lost. Anyone know?
Wrong forum, you should ask this in Q&A.
Is there no one in on God's earth connected to his internet that knows the answer to this question, or even just wants to know the answer? There's got to be others out there who want to use this phone with usb peripherals long enough to drain this insufficiently tiny battery.

Really?
Maybe you should pray for an answer.
And insufficient tiny battery?
The M8 is one of the best when it comes to battery life.
So what's your advice on otg? Don't you connect stuff to your phone and wonder how nice it would be if you could do it to your heart's desire rather than til the battery gets low? Battery life may be good for you but I'm a "power user" son.
