I posted originally in the thread that Deuce just closed while looking for guidance, but want to share something I found... I had originially bought USB-to-Micro USB cable to play USB speakers (which didn't require an AC adapter or other power source) for use with my phone while in the office or on the go; however, the phone doesn't acknowledge they're even plugged in. And that is with the phone on the most-recent- Sprint ICS stock update. BUT, they work with the Note 2 I upgraded to, which has JB, so I'm guessing it is a firmware thing. Anyway, just wanted to share that.
To use OTG on an Evo 3D, You must have a seperately powered OTG cable. The phone doesnt supply power to OTG devices, So it requires power from a charger or a portable USB powerpack.
Your phone must also have a kernel that supports Host mode to use OTG.
I'm guessing the JB kernel does then, as they work on the stock Note 2. Thanks for the info!

No it's just that the evo doesn't supply current to the usb so it doesn't work like a "standard" usb device that supplies 5v.Kernel cannot change that afaik

Since many of us plan to upgrade to a Honeycomb release, we may be interested in the USB host feature.
This brings up the question of the HTC 12pin micro USB port.
Question: If we can use a standard micro USB for typical data transfer purposes, can we also use the standard 5pin micro USB cables to attach things like mice, keyboards, and card readers?
I am thinking this might be a valuable adaptor??

USB host alone would be worth an upgrade - for me.
Apparently, USB host is not enabled in the Official HTC HC releases. We are looking into how to enable it for rooted ROM. When that is accomplished it will be posted on the forum. When software enabled the cable will be a standard connector micro-USB , possibly needing an OTG cable. In addition to the cable and software, you will require a powered hub to connect devices as the Flyer cannot supply power through the USB connector

I am very sad because my honeycomb flyer can not detect the flash disc, usb mouse and usb keyboard, though already using Belkin powered hub! Now I use mwakious rom because it is the smoothest of all the existing custom rom.
DigitalMD, is there any custom rom based on latest leak rom from globatron that can run current USB Host? Why the USB HC can not enable USB Host but the HC first leak can do it?
I am confused because on the official HTC rom there are also USB storage settings.
Without USB Host, then HC Flyer lost one of its greatest benefits than gingerbread. This problem must be solved immediately. Is it possible that official rom will be updated again?
Thank you for your help!

Now we can conclude that the USB Host is not supported by the official HC on the Flyer and View!
USB host was not available on the official OTA final either GB or HC. You cannot say it has been lost, because officially it was never there. It has been sneaked into some custom ROMs and the HC leak initially. There will be HC custom ROMs coming and we are looking into re -enabling USB Host, but it was never a generally available feature so its not considered a bug and I would not expect HTC to ever support it official since it cannot be used without an externally powered device (such as a powered hub) since the Flyer cannot supply power through the USB and this would lead to a multitude of support request calls emails etc.
If you have a favorite custom ROM developer, talk with them about adding USB host support.
But understand the limitations of USB host on Android. Most things other than USB hard drive support can be accomplished via other means in a simpler fashion I.e Bluetooth keyboard, mouse, etc. The USB host support in Android is very basic, you cannot just plug in any device and expect it to work, special devices need special drivers which are not going to be available in Android. Pretty much for now you can use things that act like keyboard, mouse or mass storage formatted Fat32 and not much else. having to use an external power source really takes the convenience factor out.
I use a Bluetooth keyboard and a Bluetooth mouse. I use Dropbox to store my files that i need to sync with in the cloud. Only occasionally do I miss the direct USB connection to large mass storage.
shoot....I incorrectly thought that host was enabled in Honeycomb. Oh, well, guess I'll wait and see what ROMS come out. Now I'm not in such a hurry to update to HC.
I think HC removed support for USB host because they did not want to deal with support for it when people tried to use it and found most devices would not work without external power and the the endless questions "will this device work?" no, will this , no, etc..
Since the hardware does not support a full USB host (no power) its just too much trouble to say its a real feature from HTC's standpoint . Just asking for trouble

I haven't gone back to the stock kernel since recompiling the source but I have my suspicions that it is there, and if not it's easy to compile it in. I've gotten side-tracked on the view hboot for now but I'll get back to it when I'm done with that.

Direct USB connection is the simplest way to interact with many basic peripheral. Many people just don't know where to buy dedicated powered hub, so they don't use it! But it's very easy using a powered hub and does not add the slightest inconvenience. We will be very understand of the USB Host limitation, as well as the limitations of other handhelds supported USB Host, although they can provide additional power to the USB.
So, please, make it enable again on Honeycomb Flyer. Thank you in advance.
As DigitalMD, I also prefer to use Bluetooth peripherals as I hate carrying a multitude of cables around. For Storage, I use a modified DIR-685 with a 1Tb hard drive as it is also my hotel firewall. You could use a http://www.seagate.com/www/en-us/products/external/external-hard-drive/goflex-satellite.
But I really think HTC have just erred with USB host.
If they disabled it, why leave it showing in Settings Storage why not remove it as in GB?
They will get more customer complaints for a non-function rather than a missing function!
solar powered usb hub
I found a solar powered usb hub on amazon that I hope will work nicely when usb host finally gets enabled. I'd post the link, but I am too n00b, it says. At amazon if you search "solar powered usb hub" its the first link. Once usb host is enabled it at least removes the annoying tether to a power outlet.

You are never greedy bg, just exploring broader possibilities, same as me.
Yeah its just my own opinion that HTC pulled the option at the last second on the final release because its was in the earlier leaks. But I just think they saw a raft of calls coming because the interface won't even power most small thumb drives. I'd like to see it working, but its not really of much use.
So I just saw a tweet about how on a SGS2 you can use a Samsung cord and are thus able to plug in USB devices. I had no idea you could do that, I knew with the Galaxy Nexus you could, but not the SGS2.
Is there any similar thing for the Amaze that anyone had heard of?

Are you talking about the USB micro/mini plug turning into a USB host port instead of a client port?
there have been hack up's for this since the N1 that even let you run a USB video card off of it (with a power adapter hacked into the USB line tho)... like this http://sven.killig.de/android/N1/2.2/usb_host/

Yea, that's what I'm talking about, but looking around online about the SGS2 all you need is that OTG cable and it works. This solution looks fairly intense, with changing the kernel and editing scripts... Thanks anyways, at least we know it's possible.
@faux said the USB OTG code is missing in the HTC kernel. so, either htc or someone write some code in the kernel or it won't happen.
Not sure if the Telus kernel is different but using the stock .config file, it seems OTG is enabled.
OTG support for Qualcomm on-chip USB controller (USB_MSM_OTG_72K) is what is enabled.
I recently purchased the note from att and my wife bought me a few accessories from amazon. One of the accessories that came in the bundle was a usb host mode cable. I've googled for answers but couldn't find anything with details for what its for. Im not new to android and rooting, as Ive owned a few devices over the years and last one being the galaxy s2 on sprint. If anyone can explain to me whats the use for the host cable it would be greatly appreciated. Thanx in advance.
BTW I love the galaxy note!!! I sold my iPhone 4S to get it and Im happy I made the switch!!
It's for use with USB drives and other USB devices that require USB host to use.

For what purposes?
You can plug in a thumb drive to the cable and it will mount on your phone. You can also use usb keyboards/mice if you are so inclined.
I carry a cable so if anyone wants to pass me a large file I just plug in my device.

I use it mostly to run this: DSLR Controller.
It's also nice to be able to connect USB thumb drives to move files back and forth.
when I plug in my usb cable I don't get access to my sd card. Am I doing something wrong
Had a brain fart...
I figured it out

i just bought a micro to usb female but my phone wont recognize the usb drive i plug in
I think the cable you want is called an OTG cable, not just a micro USB to female USB.

What about Ethernet? There are USB-to-Ethernet converters and the Linux kernel likely supports them, I am rooted so I can run netcfg usb0 dhcp for sure. Is there a reason why this wouldn't work...?

You can use it for UOTG, USB on the GO. You can plug the micro usb to the phone and plug a USB flash drive. Go into a file explorer and look for a folder called usbStorage. You will be able to access the flash drive through that folder.
FYI, make sure that USB debugging is disabled other you will not see anything in the folder.
This is perfect for transferring files from USB or other media into the phone. I use it with my Canon S100 and transfer pics directly from the media card.

I'm curious if there is an adapter for the MHL port to a female USB port. I have one for my Xoom, and since ICS has USB host support, I wanted to try it out.
EDIT: Also when I restore a nandroid, how do I restore the kernel?
i can answeer your second question... use the nand droid helper that con made... its in the dev section or flash a ph98img with the boot.img in it manually or by computer

I got one of these cables on amazon for $15. But I can't get it to work. I want to run an app that will use my phone to control my DSLR, but can't get it's free version to see anything. It acts like it can work, but never does. I hope it's just not turned on in the leaked kernal, and when we get official ICS, they will turn it on, or at least when we get the kernal source, one of the devs will turn host controlling on.
I also could just be doing something wrong, as I've never tried this before.
Edit: it's called a usb OTG cable.
I read this:
https://forum.xda-developers.com/showpost.php?p=59018285&postcount=2
So, USB is supported in the kernel basically? Any chance to make it work? And is it perhaps possible to get USB OTG via powered OTG Y-adapter cable?

Nope - several have tried convinced they could make some headway. Not going anywhere with existing proprietary kernel.
Ashame Amazon disabled OTG but (potentially profitable) cloud storage was all the rage in the early 2010s when this gizmo was conceived. Didn't want to spoil the party with cheap local storage which also raises DRM issues.
