Kernel with USB Host functionality

This is a question to the Developers here on XDA, especially the ones that are developing for the Desire HD.
I would like to point this out http://forum.xda-developers.com/showthread.php?t=694427
Like you readers have already read it's about USB Host functionality on the Nexus One.
On the following link you will find a thread of this being ported to the HTC Desire
http://forum.xda-developers.com/showthread.php?t=702742
The Question is, if there someone who knows how to get this to work on the HTC Desire HD and is willing to do that? It's not a practical functionality but it's sure is cool to have the possibility to connect your external HD, USB Controller, USB Mouse or whatever USB device on your Desire HD.
From my little knowledge i think that the modules need to be implemented in a Kernel, Maybe it would be a nice project for someone who works on Kernels? I don't know how to support the Desire HD with this feature, I hope someone can.
Kind Regards,
Shar!ngaN

I looked at this last night, but without having an adapter, I cannot test it.
I can however build you a kernel with USB Host compiled in tonight when I get home.
Would be nice to know if it will actually work
Send me a PM if you are interested.
Edit: Thanks for those links Interesting reading and info I need.
Edit 2: Adapter ordered.

I've ordered an USB Host adapter around December last year, but it still hasn't arrived. So i actually cannot test it at this stage. However i would like to see that Kernel and would love to test it (As soon as my adapter arrives).
Thanks

Question: Do you only need an adapter to connect normal size USB to mini USB? Will the dhd have enough power/voltage to run a flashstick so you don't need external power?
If i only need an adapter i'm in for testing if it's compatible with CM7
I have an adapter lying around from using it on my N900 that had USB otg/host mode

From the video's i saw of Sven Killig's, that's the man who achieved USB Host functionality on the Nexus One. He powered his USB devices trough a self-powered USB hub.

@Shar!ngaN: As soon as I get my adapter, I will start messing with it.
But as you know with DealExtreme, that can take up to 30 days to arrive.

Yes i'm quite sure you will need an external self-powered hub.
I have already purchased all the equipment i need so i just need to get into the nitty gritty of modifying the phone. I need help on this!!

I have been playing with compiling this functionality into a custom kernel, but I dont know if everything is ok.
Will read up on the other phone's thread to see if I missing something.
@Mr. Blobby: Are you willing to reflash your kernel? This will be a requirement.

Ok that's no problem, and thank you very much,
Yes i am willing to do that, however i have been told it is very risky and you need to know what you are doing when carrying out the process. As a result, i am waiting to find out if someone can help me with it as i know nothing about smartphones and i don't want to end up breaking the phone.
Thanks alot.

I have the adapter and im awaiting the kernel (hope it works with the Telus version)

Flashing the kernel is not risky as long as you backup first. Use Rom manager.

ooo ok thats a relief thanks!!
can someone please tell me what i first need to do? do i first need to root the phone as it is not yet rooted. If so, how do i go about doing it without 'bricking' the phone?
Thanks!!

Bump, any news on this

I'm still waiting too
i've got all the cables and stuff i just need to know how to re-flash kernel and root the phone etc

Anybody got it working allready?
I've gut the stuff to do it but i have no idea how to build the kernels and stuff

will be great to see it on an cm7 kernel

Too bad, still nothing

From the https://github.com/CyanogenMod/android_vendor_cyanogen/blob/gingerbread/CHANGELOG.mkdn, it seems that CyanogenMod has got USB Host included from version 7.1.0.
I am using the JellyBean - Jelly Time ROM and wish to use my DSLR via the USB host feature, but not sure how to do it yet I have the OTG cable(http://cgi.ebay.in/ws/eBayISAPI.dll?ViewItem&item=170844328875).
Any pointers anyone?

CM doesn't have USB host for all devices. In the change log - "Encore: USB host support - Verygreen". That's only for s specific device. If it was listed as 'Common' then it would be for all devices.

Rebooting when MHL is Connected [Docomo SC-04D]

I first bought the Samsung brand MHL adapter, and the moment i plugged it into the phone, it simply reboot without displaying anything on the TV. I figured it might be the adapter, so I returned it and bought a 3rd party Menotek adapter only to find the same problem.
The power cable is connected to the adapter, and the adapter to the phone and HDMI cable. I even tried a different power cable, and wall charger and same problem occurs.
Is this a problem with anyone else, one that has a fix? If not I might have to exchange my phone, since this is a feature I really wanted.
Could it be perhaps that the Docomo (Japanese) version uses different electric current that it has to convert, but the adapter can't convert?

i have the exact same problem.
at first i thought it was the cable, so i exchanged for another one... it rebooted.
then i thought maybe it's the tv, so i tried a friend's tv... it rebooted as well.
so i figured it must be the phone. but then since everything else was working perfectly on my phone, i couldn't be bothered to go exchange it... i thought i'd hardly use the mhl if at all. guess you should go exchange yours while you still can though.

I'll contact newegg about it, see if I can get a hassle free exchange.
My biggest guess is that is has something to do with the 110v/220v electrical current that it either doesn't receive enough, or too much, causing it to restart.
I am not sure what a good solution is. At least I am not the only one.

hmm i doubt it's got anything to do with electric currents.
it's my understanding that standard usb power is 5v.
anyways japan uses 110v same as US, and i'm in asia 220v and we're having the same problem.

I had same problem as this but the jelly bean update fixed it....

110/220 is AC, which is converted to DC before it even gets to the usb cord, let alone to the phone. Most chargers will support 110 & 220, so there shouldn't be any issue there.
Are you rooted? Have you tried any other ROMs?

i have the same problem and the jelly bean update doesn't fix this problem, any solutions?

I9250 suffers from defect as well
I have problem. Using i9250 original international version. MHL worked once upon a time, jelly bean didn't fix it, started in 4.0.4, last worked in 4.0.2, dont care about downgrading just to examine, but going back to stock 4.0.1 or 4.0.2 might fix it

[Q] Nexus doesn't get power anymore when on

Hi guys,
Since yesterday my Gnex doesn't get power from the adapter anymore when it's turned on. Only if I shut it down, it will get power.
Also when I connect it to the computer, it says: "device is not recognized".
Can anyone help me?

i don't know, your phone is dying?
those of us who have never experienced that particular behaviour, we need something more.
please provide more information; ac/usb charging or both? other charger/cable? running stock, stock+custom kernel, custom rom? list the apps you have installed. fastcharge y/n? if you turn it on after it begins to charge, does it keep charging? have you tried another battery? how do the pins/usb port on the device look: dirty, bent, any kind of damage?

Before thiis happened, I didnt change much things at my nexus. I use AndroidHD rom for quite a while now, and didnt install any new apps.
I tried several chargers but nothing is working. Only of its off, but even then it says its charging but thats not the case all the time.

reflash stock images if you want, relock bootloader, turn it in for warranty, if you checked usb port state.

The problem is that my pc doesn't recognize the phone as a usb-device anymore, so it will be hard to change it back to stock and locked bootloader. Or do you think there is a way? I would like to here it
I also tried different chargers, but it doesn't change anything unfortunately.
Thnx for trying to help guys, it's appreciated.

I've looked at the post, re-locked the bootloader --> that worked.
Now I want to download the ODIN.tar files for de Odin Mobile app, but I can only find the .tar files voor Verizon models.. I however have a GSM model from a Dutch carrier.
Do you have a link for ODIN.tar file(s) for the GSM version of the GNex?

Mine just started doing this as well.

You're not on your own. I'm having the exact same problem with my Galaxy Nexus. since a couple of days.
Only way I can charge it is by turning the device off. Then while its rebooting plugging it in.
I also have the 3 dot connect docking station. Same problem with that way of charging... So I know it is not the USB thats faulty.
My device is rooted. with superuser permission. no special rom. only a different launcher,
never had any problems with it. and I did not change anything in my phone for 2 weeks.
I have no clue how to relock my bootloader without USB.
Casparovic i have a GSM model too. also from a Dutch carrier Vodafone.
Ill try Jubakuba his guide.

Well, I relocked the bootloader (without usb), but it's still not charging when turned on.
I can't figure out what it is. Also i can't send it to the carrier because it's rooted.
Can someone tell me how to go further?

I have the same issues, I just bought 3 spare batteries, and only 2 of them work on my Nexus. So basically I switch between the original battery and the extra battery I bought and charge them with wireless chargers. Very inconvenient, I hate samsungs absolute garbage quality, never again.... 6 years of a loyal HTC customer, guess this is what I get lol

Having the exact same problem. It won't charge when connected to the AC adapter as well as through USB. Computer doesn't always recognize it either.
It does charge however with my rocketfish car adapter and a BlackBerry ac adapter.
Not sure if this could related to the OS, currently running Cm10 v1.7. Or is it something else?

I have had the same problem running Jellybro and AOKP.
Only way to fix it for me was to go back to stock and wipe everything on the internal storage. Then unlock, root etc.. all the way back to whatever nightly I was running and put all my apps and data back on.
This has happened 3 times now in the past 2 months. I really panicked the first time!!
Also, sometimes I have had an issue with it showing that it was charging when nothing was plugged in! Same method to fix... oh well, the price for being a rom flash addict...

Mine randomly started working again. I've been on cm10 nightlies since they started, never changed the kernel. I also have 2 Hyperion 3800mah batteries and the stick battery. Everything charges like normal now.

Well I haven't been able to unroot my phone so I thought it just take my phone to my carrier and get it Fixed,
There the Tech guy Told me.. that you are alowed to root all nexus phone's. So basicly there is no need to be scared. just take your phone to your carrier and they will fix itt.:good:

Help with Making USB cord to mount Moto 360??

So I had a cord working for some time with a different Moto 360 I moved things around and could not connect for the life of me. So I swapped watches at Best Buy thinking I messed it up some how. Now I have a New one and I want to Unlock the bootloader to force the update via shell and I cont get this thing to mount for the life of me it acts like it mounting every time and error unknown USB device and I know my drivers are installed right because I already went though this. I would love some pic of different Modded USB cables and or what you guys have used to mount via usb and I would love some advice. I was going to sen one to someone else because I had them working and now I don't know what it up. Thanks any help or advise is welcomed .
I have tested every cord I have tried to use with a Multimeter.

Well I spent hours of messing with it but try using like a tooth pick to help make sure the pins are in the hole also double lapping the wires in the Cat 5 helped. I will have it working fine and then it will go on the fritz I recently dissed Windows in a whole and went to Linux mint witch I have had way less problems until today with a unrelated problem.

Anyone know a place where can buy one allready made? Thx
