[Q] USB host for front facing web cam/dolby speakers/keyboard - HD2 Accessories

This thread has probably been discussed several times, raising it again so some solution can be worked out.
Several websites claim powered devices already work with the HD2 as usb host. Is there a solution in sight to enable a plug in front facing webcam/dolby speakers/atsc tv tuner/tv out for the HTC HD2, all features htc conveniently did not include with the hd2 but plans to include with hd7?
Would be great to have a plugin at the bottom of the phone that included the above, the ultimate lifestyle accessory for the hd2.

Kaiser and Power Point

Does anyone know if it is possible to use Kaiser to project a power point presentation, bypassing the need for a laptop, and without the use of an intermediate device like the Margi PDA presenter? I read that the new HTC phones may be able to do that, if so is this a software or special hardware wiring? is it a function of the device being VGA or qVGA display? I would appreciate an explanantion by one of the experts.
You are hearing about a technology that hasn't yet been released... it will be a micro projector built into the phone or as an ipod sized accessory.

If you mean the sort of video output dongle thats possible to use with the Touch Pro and other devices, no it won't work if used with the Kaiser. I've not tried it with my Kaiser, I've just read it here somewhere on XDA-DEV that it doesn't work with a Kaiser.
I am talking about the ability of the new devices e.g. Fuze to connect directly to a TV or slide projector using a special cable from the mini USB on on one end and has RCA connections on the other to attach to the external display device. See this:

Kaiser doesn't support/have the TV Out feature, this was asked and explain before, just search the kaiser forum and you will get your answer.

[TT] Peripherals possible?

While looking around my phone I came up with a couple of thoughts. First would it be possible to make devices that plugged into the miniusb port on the top of the phone and could it be plug and play? Heck maybe even make the driver if necessary built into flash memory on the new device. It seems like it just takes an kernel update to make something like this possible if it's not already.
The second thing I thought of is if the above isn't possible, why not create an attachable mirror that sits at the right angle to take advantage of the rear camera for video chat. You could project your image onto the mirror and the camera could catch that. The top idea is alot better, the bottom requires alot less knowledge. Either would get us video chat.
Interesting, i like the first idea.
I like the first idea, though for video chat I would rather someone figured out where to pick up the actual modual that goes inside the phone (there's a thread about how they left the mounting brakets in place for the front cam.)
However for other things, like maybe a gamepad+extended battery combo, or an IR blaster to operate my TV

This is the thread you were talking about.
From what I understand about micro usb is that there are five wires/confections. The outside connections are ground and power. The two next to the ground are for data (one + and one -) and the last one next to power is a identification connection. If the wireis connected/has power then its a source device (i.e. computer). If its not, then its a peripheral (portable hard drive, out in our case, our phone). Its been a bit since I read up on that, so it might be vice versa.
Last time I tore the phone apart, I didn't look, but it may be a setting that is hard-wired (literally), or its a switch controlled by software. If it's the latter, then its possible, if its hard wired, then its not.
Adding things to the kernel or loading drivers isn't cut and paste. It takes available source code, which isn't always available, for both the phone and the device you want to use (that works with android), as well as understanding of how to make it work.
That last part I am not well versed on. But we have a couple devs trying to get the vibrant opened up. They are few, and the request list keeps getting larger.

I was just thinking today that it would be great to have a micro-usb device that could house a camera for video chat... I like your mirror idea...I'm prius owner and that's how the dashboard works. The usb is right there...really I think someone should incorporate a device in a mod of the back cover...i don't know anything about code but I could make the case.

Devices require a driver of some kind so the controller knows how to talk to device. For example, if I wanted to hook up my DSLR and control it, I would need a driver ported over and then the SDK for the camera would have to be ported over. An OS like Windows 7 has literally thousands of drivers built in and many other devices require you to install a driver. The only time "plug and play" actually works is either with the OS has the driver already installed or if the device is designed around a generic driver.
Incredible idea! I'm going to make the second idea. I have my own twist on the concept but it shouldn't be to difficult.

I like the first idea but I also had a similar idea and I'd like to see the attached camera come with led's and somehow acct as a flash for both cameras. It could be tiny, if the camera app could be figured out to trigger the flash on all galaxy s models, well at least the vibrant and captivate this could sell.
If a third party app was developed it could be added to any android phone in theory. If that third party app was as good as the galaxy s stock camera app then you'd really be in business.
If I was talking to my brother I'd have tried to convince him to help me develope something. Well I hope one of you talented devs has success with this idea. I'd also like to see success with the guy adding the extra camera internally, I'd be interested in performing the mod if the software end is figured out.

That's the thing, devices that support USB host generally don't use a mini/micro B port. They have specific ports for that. Of course, the USB controller in there may well be able to be a USB host, but we don't know how to enable that from what I have seen. IF the controller can be put into host mode, loads of options like this become possible. It would require kernel mods, but that's not a huge deal. However, as long as we are in USB client mode, the only things we can connect to the port are chargers and computers, as that's all the phone knows how to deal with.

Makes me wonder if you can still take power off of the port and communicate to the device via blue tooth. But I don't think it would come to that.

Oh, it's host mode built in already. One of the major pluses that I weighed in on when buying the phone.
"Both the S5PC110 (smartphone chipset) and S5PV210 (its netbook alternative) are optimized to ensure long battery life for mobile devices, using a 45-nanometer (nm) Low Power fabrication process and low power architectures. With the 1GHz clock speed and 512KB L2 cache, these processors should also manage to provide performance unknown to the ARM world so far.
The two processors have built-in 3D graphics engine and support 1080p full HD video playback and recording at 30 fps. The final nice features of the new chipset include a wide variety of interfaces and peripherals, including HDMI 1.3and USB 2.0 host interface."
Hate to kinda go off topic with the USB Host mode stuff again, but it seems like since the interface is built into the chip, host mode should be enabled in the kernel.
Yes? No?
Has anyone tried to get an OTG cable in there to see what happens?
Just saying.
I've been curious about this since I saw it done (rather impressively) by sonic7406 (YouTube) on the Nexus One. Since then, I hear it's also been hacked on the Droid. From my research, I'm pretty confident this should be possible with the right drivers installed on the Galaxy S series. I've gathered together an (supposedly) OTG "compatible" cable (the Nokia CA-101 for Nokia 6600 Slide/N900/etc), an extra-beefy powered hub, and female-to-female USB-A adapter. I have yet to dive into the kernel to load any special drivers, try mounting drives, etc. I'm still unsure of the "OTG" cable and may still need to manually ground that fifth pin to kick it off. Though, as far as the cable is concerned, that is the only thing that makes it OTG on one end.
Host Mode Background Info: OTG Wiki
Here's a modoco thread that includes most of the relevant links I've seen.
Ideally, I'd like to find a microUSB to USB-B OTG cable that connects directly from my phone to the powered hub, but I couldn't find any. Let me know if anyone knows where we could find these.
It seems like we could create an entire new category of toys to attach to our devices if the micro USB port could be figured out. To me that's ultra exciting!
Let's go a few steps further, Being able to physically attach a printer or hdmi (Yes, I know about AllShare) to the tv could require a simple adapter that plugs into the micro USB port on the handset. We could also have a nice flash that has brackets that mount to the handset for support to get better pics in low lighting (instead of just saying "oh, I've got night mode", bugger that).
The capability to do this has to be written at the kernel level and then we need hardware manufactures willing to make the products. Therein lies the problem, how do we get that to work?
My neighbor is an electronics engineer and I'm a machinist, my friend is a tool and die maker.
My neighbor has an idea to make a device for surface mount soldering using an inert liquid with a boiling point equal to the soldering temp. This would be a cheap alternative to infrared soldering.
Other than that I might be able to come up with a housing.
I wouldn't want to commit myself untill the software works and we've tested the soldering machine.

Do you think will GTab have USB host?

You may not know how useful USB host is. You can use USB stick (up to 32GB), USB keyboard, USB mouse.
If it had USB host, I'd buy it for sure (wifi only).
Sadly NO...
On German Amazon its possible to pre order the device and the datasheed isnt saying something about USB Host
http://ecx.images-amazon.com/images/I/B1gfmv71YkS.pdf
http://www.amazon.de/gp/product/B0041RSF6Y/
This one was my favorite (because of the Phone capability) until you asked this very good question
Maybe they got it rooted in future and then its possible? (depends also on hardware...)
Greetz Tokl
I'd guess that its not going to ever have the capability without hacking. I don't think any device has that at the moment.
I guess what gets hacked depends on what the hackers think is worth doing, and I can see that USB host would be an especailly awesome thing for the Tab so hopefully it will get some interest.
If its a game breaker, you may well be disappoited for a long while tho. This kind of hacking doesn't happen over night.

This is SO true. I remember people trying for years to hack USB host mode in to Nokia's Linux Tablets: the N770 and such. I wonder: Did they ever manage to do it?

Please someone correct me if I'm wrong (as I don't have the device in question) but doesn't the Nokia N8/E7 support just that? I seem to remember a video demonstration of the N8 supporting an USB memory stick.
Also, the Tab will have a dock that has a keyboard, so it's not totally impossible for it to have USB host capabilities.

I don't know about the N8, sadly I just don't have much interest in that part of the mobile space. However, some googling seems to indicate that it is possible (news articles say so) but I don't know if its naitive or needs hacking.
As for the keyboard and stuff, thats a good point. I can't see them using a non-usb standard for that, so it must just be the proprietary connector that makes the difference. In that case, all we should need is a Tab-USB connector, and a few drivers. That would really give the tab some muscle.
In general can mobile devices support the USB min-harddrives ? The ones that power from the port ? If thats possible then the tab will kick serious ass. 250 gigs in your pocket for cheaper than a microSD card.
I'm not really a fan of Nokia's products either, although they USED to make great products they haven't done so in awhile. And I *hate* Symbian. Anyways, at least the N8 DOES have some USB Host capabilities:
"Among the Nokia N8's neater tricks is its support for USB On-The-Go, which basically lets you connect USB peripherals (flash drives, for example) to the phone and have it act as a host..."
http://www.engadget.com/2010/05/30/nokia-n8s-usb-on-the-go-support-demoed-lesser-phones-turned-in/
That was almost perfectly offtopic, sorry for that ^_^
Oh, or not, perhaps! Look what I JUST found:
"USB Standard port adapter
With this kit your Galaxy Tab becomes a standard USB port. With this USB port you can synchronize your digital camera or other devices."
http://www.oled-display.net/more-sa...s-bluetooth-pen-standard-usb-adapter-and-more
Well if they are going to officially make an adapter then maybe we are going to get USB Host... I can't see how you could transfer things off a digicam without the Tab hosting it as a drive.
Well... This looks pretty awesome then.
But they *CAN* cripple the functionality to just mass-storage devices or perhaps just cameras, like Apple did with their USB Camera connection kit, or whatever it was called.
Let's just hope that Samsung doesn't go that route.
Hopefully samsung aren't that stupid Although in theory we should be able to hack it back open anyway, and its a good start at least.
Sorry to resurrect this old thread, but I'm also wondering about usb host (or at least OTG) on the Tab (as I'm considering buying on to port Meego to).
Could someone who has the keyboard doc post the dmesg output once it's been plugged in please?
From some dmesg output I saw elsewhere (but not with the keyboard dock), it appears that the USB chipset is an OTG version, and seeing it act in host mode with the keyboard doc plugged in would be a nice confirmation.
I Would be interested to see the anser for this one.
Yes it is launched (mainly for photographers) i have seen it's price, very cool cheap at £10000 plus something!

It's not the Fools Day yet, so keep your jokes at bay.
OK, I just ordered a keyboard dock and I'll have a look. I'll post a dmesg output and open it to see if the PCB is marked in any way.
According to the pinout (http://forum.xda-developers.com/showthread.php?p=9925838) there seems to be no other way for data to flow apart from USB.
So one of the following must (should) be true:
1. Samsung is reusing the pins for a proprietary protocol -probably reconfiguring the device by pulling up or down other pins.
2. The device is capable of host/OTG mode but it is probably unpowered and it probably needs a pin pull-up/pull-down to enable.
3. The keyboard is using unidentified pins, and the USB pins are used simply for the PC connection and power.
Does anyone know if the keyboard acts as a proper dock? i.e. when you connect it to the pc does it work at the same time as (say) KIES or drive mount?
Just a quick update, the keyboard was just shipped, and I should have it by Tuesday.

USB host
This is a good concept. I have an Archos 70 and a Galaxy tab. Archos has a micro usb port with which I connected my USB host adapter and the key board and mouse works . Flash drive and router dongle says more power required. So I am looking for a powered USB connector for this.
Unfortunately, Galaxy tab has different cable and I dont know if I can find a host cable for this. Any suggestion?
Worth a shot?
After reading this thread:
http://forum.xda-developers.com/showthread.php?p=9925838
I checked the G-Tab pinout :
http://en.wikipedia.org/wiki/PDMI
and tried to ground pin 13 to put the tab in host mode last night... needless to say since I'm typing this on my computer... epic fail. However, I'm curious if anyone else has had any success with this.
I'm not too much of a fan of buying something to destroy... but if I have to disassemble a dock to get the pinout for monitor mode... suck!
Anyone have any advice as to what I jacked up here?

Nexus 7 Car Install

I've decided to put together a Nexus 7 car install after pricing up an OEM retrofit for my E90 & quickly getting north of £1200 with no guarantees that everything would work as I wanted.
I've used Android devices to provide navigation & audio since getting a HTC Desire many years ago, but I've been caught out a couple of times recently using navigation on long journeys with my HTC One-X completely flattening its battery despite being on charge the whole time!! The last time left me navigation-less in a strange city, in rush hour traffic, with no way to contact anyone.
I've been reading around Nexus 7 car installs today & everything that I would like to do seems to have been done before, but I'd like some ideas for the best way to pull it all togther.
The main use for the Nexus will be to provide navigation & audio. I gather that Timur's kernel - USB ROM contains features which are suited to using the Nexus in a car install - are there any other ROMs I should have a look at?
I would like the install to look as professional as possible but be removable & reversible, so I'm thinking of a mounting it in a SHG-NX2000, & I would prefer to use a single USB connection to the Nexus rather than a USB & 3.5mm so from my googling today I gather I can achieve this with an OTG USB cable & a USB DAC.
I've not used an OTG cable before, but the ones I've seen on ebay seem only to be a couple of inches long - can anyone provide a link to longer one or can I just use an extension cable & stick the OTG cable near the hub? The idea I've got in mind is to run the host OTG cable from the Nexus into a powered USB hub located in the glove box or behind the dash. I would supply the power to the hub from a DC-DC convertor to make sure everything gets the power it needs. Are hubs usually wired to supply power to the host device as well as the connected devices? Are OTG cables available which allow the power to be supplied to the host? If so, I could use one of the ports on the powered hub to supply power to the Nexus via the OTG cable.
I don't have a spare line level input to my stock BMW headunit, but I do have an aux in on a 3.5mm socket which I don't mind re-routing & hard wiring to the output of the DAC - can someone link to a USB DAC best suited to this task?
I would also like to install a reversing camera. There are cameras available which either replace a license plate light, or mount around the license plate - I would prefer to use one of these over a webcam. I had an idea of using an Easycap to connect the license plate cam to the USB hub - has anyone done this? The license plate cams pick up their power from the reversing lights - is there a way of using the fact of the camera powering up to switch the Nexus to auto display the feed from camera when the car is put in to reverse? Taking this idea a step further, has anyone configured a system where if the car is then subsequently taken out of reverse gear the Nexus switches to a forward facing camera either for a fixed amount of time or until reverse gear is re-selected to give you alternating rear/forward views when parking up?
Shopping list so far:
Nexus 7 (1st gen) £119
SHG-NZ2000 £22.39
DC-DC convertor £5.50
10-port powered hub £6.19
Micro USB OTG Host £1.99
E90 License plate light CCD camera £17.00
Easycap £3.37
USB DAC £11.49
Total so far ~£185
Anything I've missed? Better components? Cheaper prices?
Any help or ideas greatly appreciated
I would think the only way for a rear cam to work is to modify it and your tablet ...no usb input... You could try to use the housing of a rear cam and put a web cam it and seal it up good then use that .... That way you'll get a wide veiwing angle ....

I'm not sure I understand what you mean by 'no usb input'? I'm talking about connecting the CCD camera via the Easycap to the USB hub which is connected to the Nexus. It is because I don't think I'll be able to reseal the housing well enough that I don't want to use a webcam, plus the CCD cameras are powered when reverse is selected which I'm hoping should make driving an event easier.

Hi there,
I was just wondering if you had any success with the camera? I've got a Nexus 7 install and want to wire in my existing Rca cam. I'm sorting out the reverse signal with a joycon exr steering wheel control but I want to know if the easycap thing you linked to earlier worked as a capture device on Android or whether I'd have to go for the UVC grabber in the other link which definitely works but is much more expensive!
Thanks!
Any update on these types of cameras?
I want to do the same thing, except the camera is in the front (not the back).
Any success with the EasyCap? It seems they have bad reviews on amazon, but maybe they work great for how we want to use it.
Also, have you tried using a 4 channel EasyCap? That way we could hook multiple cameras.

Any MHL Friendly roms?

Hey I'm working with a HTC Raider with a smashed screen, seems like there is one with a broken screen every day on the buy/sell/trade sites. Picked the phone up for dirt cheap, now I am looking to set the phone up as a media server/speaker to HDMI via the MHL function.
I got it to s-off so far (tricky without a screen) but now I am looking for an ROM that will still work with MHL.
