Possible to access a USB flash drive

Does anyone know if it is possible to use the mini USB port to access an external hard drive, and/or a USB Flash drive/card reader.

You would need this: http://www.casecooler.com/usbab5pgech.html
for starters then you would need a program to know how to read the drive.
It is defintely possible just not sure if anyone has taken the time to do it.

It would be very useful. If someone is already interested?

my understanding is that it is not readily possible due to the device not being a USB host device.
Google it or search these forums (not just kaiser) and you will see a lot of talk about it.

Please do your research before use the phrase "It is defintely possible". For a start, when it can be connected doesnt mean it can be used. I can come out with an adapter which converts the USB-mini to a 240v-wall-plug, and it doesn't mean that you can charge your phone directly on a 240v AC power. It is like saying, if I were to use this, I'll be able to send my music from the phone to the car stereo.
The plug/socket designers came out with various plugs and sockets for a reason (i.e. so that people dont simply plug things together that does work).
Anyway, you should check on the topic 'usb host'.

I started working in this direction smtime ago but then got busy...hopefully if i get sm time in cming months, there might be smthing on the offer...

Generic USB devices on HD2?

Assuming USB hub functionality is present on the HD2, does anyone know if standard USB devices (e.g.generic keyboards or standard USB memory sticks) could be used on HD2 without having to install special drivers?

I'd like to know this to!
And like the G02, can I use a gamepad on this baby?

Given that USB host isn't supported how do you expect the device to have the drivers for it?

According to various reviews I've seen, USB host is supported.

sent them a mail
hello, just a quick question regarding the new HTC HD2,
does is "support" USB host, i.e can I plug in ,say, a USB memory stick (Generic devices)?
best regards

lets see how fun the answer will be...

Well, there are no drivers for peripherals in the leaked ROMs, no official information, nothing that would really indicate USB host support. It may be enabled somehow via hacks, but that would certainly mean that drivers need to be installed separately.

got a reply from HTC today;
"It doesn't support"
thats a shame really, hoped it would have... no TV out and no usb host, that sucked

how would it work to extract the host drivers from another device?
Could they be used on the HD?
(I think not after what I have read, but it just might work)

may be you can try thoses drivers :
http://forum.xda-developers.com/showthread.php?t=480899
and some proper cabe because you may have to add a input power cable and see if it works and tell us

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://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...)

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.

Hi,
Just wondering whether you got any further with this?
Sent from my GT-P1000 using XDA Premium App

There was a problem with my order (the company didn't have any in stock) and the keyboard hasn't arrived yet. Still waiting!
I'll post the moment it arrives.
EDIT: Normally I would name and shame the company, but they are sending me a couple of freebies for their mistake so I'm happy

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?

[Q] USB Host on P9xx

Hi all, I did a search under this forum and do not actually found any info.
Actually, many older Android phone/device do come with USB Host (OTG) function, hardware or software, with hacks or officials,
Mod/Hacks:
MOTO droid, N1, ZTE Blade, etc
Officials support:
Samsung GS2, MOTO Xoom, MOTO Atrix4G, EEETransformer, Many CN crappy Android Tablet.
I tried using a OTG Cable with a USB thumbdrive on LGP9xx but no luck, browsing thru the system I found that there are USBDisk DIRs on / or /mnt/USBDisk, there are no define on vold.fstab at all on LG, not like the MOTO Xoom..
dev_mount usbdisk /mnt/usbdisk auto /devices/platform/tegra-ehci
So my wild guess is it was not turned on kernel level?
As far as I can tell, there is USBHost OTG support on Tegra2, seen post related to that on that, I understand that hardware might not be wired (that's what we gonna check), anyone any info/hints/directions/ideas about this on the LGP9xx?
It would just be great if we can use OTG on LG99x...
thanks.

It needs to be turned on via menuconfig. I could do a quick compile later, if you want. The downside is, that a enabled USBHost disables the slave mode. So no mass storage (Or you implement something like holding back while booting up etc to enable usb host)

Wow, that's a quick and straight to the point reply!!!!!
I think I can live without a slave mode, most of my files are copied to the phone by samba, dropbox or ftp....
just wonder what trick did SGS2 or others uses, I know many of the devices which support OTG has 2 diff USB port, 1 for host and 1 for slave, but I "think" got that working too in 1 port, wonder is it the same as our case here that needs special reboot or so? (SGS2 is not available here yet...so I have never tried it instead of watching in on the youtube VID online...)
Anyway, THANKS! waiting for your releases. thumbs up to all DEVs!!!!!!!!

Don't know. One part maybe only with other hardware drivers. The reboot solution would be best for us (but needs some work). So the easy enable via menuconfig would be enough. Anyway I started to working on this, but I don't know if my otg cable isn't working (slave function was disabled but host didn't worked). So I wanted to test it anyway. What do you need? only mass storage?
The compile could take a while (working on fixing cust toolchain build)

I am aiming on USB thumb drive, keyboard and mouse..thx..

Honeycomb 3.1 has USB Host support.
Hopefully someone can pull it out and use it somehow.
Since there's no source it might not be easy.
Or you can just wait for Ice cream Sandwich(Q4 2011), i'm guessing there will be Host support.

Any news on development?

i think the usb port of phone has no more power to use the flashdrive.

So is this a dead project? Or is there any hope left?

Not being picky or challenging to admin, I originally post this thread under development, which is should be more related since I am not asking generally how to "use" USB Host but related to kernel/drivers development....
I think this thread in general would not actually get much development attention at all...
Anyway, nope, no news, I understand hacks/dev is not a piece of cake, thanks for everyone who is working on the topic here!!!!!!!
and since CM distro do not support USB host at all, then I would suggest there may not be enough attention or momentum at all on this...

I may not agree, I did use a O2Graphite with a USB host cable with a USB jostick, and keyboard+mouse on many CN made crappy Tablets, they just works...
Many USB devices do not drain that much power, especially some Flashdrives...

Hello
So is this thread as good as dead, or is anyone trying to develop this?

as far as seen on the thread, it seems dead.....

hello
the usb memory stick must be formatted in fat32 to work.

Which specfic cable works with it?

Nothing works with it, no-one has produced a kernel with OTG support for the P990.
No idea what that post is about.

External screen?

Hey!
This is my first thread I've ever created, so don't be too harsh on me
As far as I know, the new Android 10 includes a so called "desktop mode". So you can connect a compatible device via USB to an external screen. I think thats pretty cool and samsung already implemented this idea from the S8 upwards with Samsung Dex.
I understand that this needs USB 3.1, but the Motorola G7 Plus only has USB 2.0!
According to the datasheet of the build-in Snapdragon 636 processor, it does support USB 3.1!
So here comes the question: Is it possible to "activate" the required functionality in order to use the desktop mode?
So like changing a few things inside the root files (Like you can activate for example OTG)?
If not, is the hardware build that way, that it just doesn't have the data-lines?
And also, if all of that doesn't work, you surely saw such USB 2.0 to HDMI adapter, which do work on older computers, but do they might work with Android 10 connected to otg?
It would be really cool if something of that might work.
Thanks for your response!

Unfortunately this device does not support MHL so usb to HDMI dongles do not work. Apparently moto hasn't supported MHL for some time .

Thanks for your answer. But I knew that before. I am trying to finde some "workarounds" for this, because I do really like this phone!

Found a solution
So, after a bit of research, I found a solution to add external screens to any OTG compatible Android phone!
There are so called "DisplayLink adapters" and those seem to be compatible with any Android phone that supports OTG.
After installing the official app "DisplayLink Presenter", you should be able to get everything working.
I din't tested it yet, but I hope that this will help someone in the future.
