First time I've tried to start a thread. I know that that USB host works on the Nexus one and Droid X. I'm not sure if it should work on any Android device as long as the correct drivers are used. I also don't know what file structures it can recognize (i.e. NTFS).
Anyone care to join a discussion about the possibility of doing this on the Epic?

I've been searching but I haven't been able to find an answer...does the hd2 support USB host while running android? I'd like to b able to connect a web cam to it...I've have also found Bluetooth webcams, also wondering if using one of those with the hd2 would b possible....I'd just like to b able to video chat with the hd2 and I wouldn't mind carrying an attachment....

Hello,
Is there a chance to have USB host on HD2 under android builds ?
If not can we know what is the main problem ?
Android is based on a linux kernel isn't it ?
So, if USB host is supported under linux builds, why is it impossible on android ?
Thanks to teatch me !
I don't think android in general allows USB host on any device... that's the problem. The linux kernel supports it, but android doesn't. If you use ubuntu you can have usb host on the HD2.
Actually, the Notion Ink Adam runs Android and has USB host mode. With a bit of kernel hackery, this could well be possible on the HD2.
Using a USB Y-cable and providing external power, it should be possible to connect all sorts of things. I'm patiently waiting for this capability as I have a USB SSD HDD that I connect to my car's head unit that I'd like to connect to my phone when I'm at work

You're right, I have seen other android tablets with usb host, too. I remember seeing the devs explain somewhere why android on the hd2 doesn't have usb host... I thought I remember it sounding like it wouldn't be able to happen until a later version of android... but I could be wrong or misunderstood. I'll try to find where I read this.

Hi.
http://forum.xda-developers.com/showthread.php?p=10797562
It's an easy way to use the USB connector in host mode, works under ubuntu.
with some adaptors you can build it also by using an y- cable.
But I think android for HD2 doesn't support anny usb features until now, perhaps someone will activate it in the kernel.

Yes, most of us are aware that host mode is usable whilst running Ubuntu. The problem is that Ubuntu is not really convenient as a main phone OS; Android is and some devices seem to have host mode while running Android.
Hopefully one of the devs will see this thread and give some insight.
what can be done via USB on the nook?
can it do host mode? (to connect to USB accessories, I would assume the need for a powered hub as I do not epect the nook to be able to power the USB bus)
with the standard firmware it acts like a drive when connected to a PC, with the cyanogen firmware, what other devices can it be made to look like? I haven't been able to access it as a drive since flashing it.
can the USB be made to look like a network?

Look in the Dev section. They're working (and getting very close?) to being able to do this (hello external hard drive!).
which feature are they close to getting working?
The one where we can have hosting enabled
So...everything-ish
glad to hear this. any pointers on what threads to look at? (unfortunantly I'm not allowed to post questions there yet)

Under deveopment, but working for some devices. Take a look here:

I'm looking to get a tablet to introduce BackTrack 5 to. I don't believe this tablet has a wifi chip capable of injection, so I wanted to connect a USB wifi adapter to it (this one right here). I read in the update it's able to register the usb port for usb devices, but which exactly work without me having to create a driver? And, I'm sure there are linux drivers for said USB adapter, I assume I could take that and (easily) create one?
From what I've read so far, the USB port handles things like hard drives, keyboards and flash card readers (and not necessarily all of them).
A Wi-Fi adapter may function under Linux but you would probably have to be rooted on the device to install drivers since they are not natively included in the system build that I know of.
Backtrack 5 works fine on the A500. I'm running it right now. I've had no issues with it.
i posted a thread in the accessories section on compatible usb devices

Do you have any success with it or just running it

I am thinking about putting Backtrack on my Iconia A500. Following up on a previous question by NickkxNekro, would one be able to plug the Alfa wifi device into A500 and make use of it?
im assuming yes since you can use 3g usb dongles
Hi,
I was hoping I could post on the developer sub forum, but I have too little post, so I hope some of the devs can help me out.
I have in my possession a USB OTG cable, and I am able to connect it to a usb -> serial port, and send/receive data to and from a PC's hyperterminal. I am also able to send/receive data to and from one of my custom boards (something like arduino) that has a serial interface.
I've written my own program to perform this communication, but it is largely based on
- Slick USB 2 Serial
- USB Serial Monitor Lite
from the playstore.
Now, I am able to perform the above with my Samsung Galaxy S3, however, when I tried running my program, or anyone of the above programs (from the playstore) on one of the china branded tablets, which claimed to have USB host mode, it didn't work.
The tablet that I bought is ICOU7.
Now, I am desperately trying to get my program to run on a tablet, but I do not want to buy a tablet, and waste my money (which I already have with that china tablet) if it doesn't work, so can any of the devs out there, with a Nexus 7, confirm that the Nexus 7 is able to perform serial communication with PC/board through an OTG cable?
Do I need a specific OTG cable to do so?
I can't say for certain that it supports serial connections but it does have host mode. I've used keyboards/mice & flash drives without problem

Depends on what you mean by "serial" device. If you mean CDC/ACM class usb device, then yes, nexus 7 can handle those, it creates /dev/ttyACMX like on desktop linux. This is only accessible if you have root, though. But, ACM devices are also supported by android USB Host API, which means you can write android app, which communicates with such device, and it does not require root.

How about for starters, I just wanna communicate with a PC's hyper terminal through its comport? Will Nexus 7 be able to do that?

The china tablet I had was able to support mouse/keyboard too. But it was unable to establish a link to my PC's hyper terminal, which I was able to do with my unrooted Samsung S3
Greetings....
I am hoping to get my Asix Usb to Ethernet adapter working with my nook STG. I believe the only remaining requirement is to compile the drivers for it (which are android 2.x compatible according to the driver manufacturer website).
I am rooted and have 'usb host mode' successfully working.
When my adapter is plugged in, it displays as a 'connected device' in my Usb Host information app and shows the details; make/model etc - so its connected successfully.
It works plugnplay with my other droid devices, however in these devices there is an Asix driver folder in /sys/bus/usb/drivers and there is not in my Nook, thus I believe i simply need to compile the drivers which will create the Asix driver folder.
If you have the correct setup and can compile the drivers for me (and potentially other Nook users), i will exchange them for 10GPB or 10 of your currency, via your desired means.
I am slowly trying myself on an ubuntu vm in windows but can only use the pc for short periods due to eye troubles; hence trying to use a Nook as my sole computer.
INFO:
Device: Nook STG firmware 1.21 - kernel source file link = images.barnesandnoble.com/PResources/download/Nook/source-code/nook2_1-2.tgz
Adapter Driver: Asix AX88772 - driver source file link = www.asix.com.tw/FrootAttach/driver/AX88772C_772B_772A_760_772_178_LINUX_Driver_v4.11.0_Source.tar.bz2
Adapter Info: BobjGear Adapter made for Android Tablets = www.amazon.co.uk/BobjGear-Ethernet-Exceptions-Description-Ultrabooks/dp/B007RTACDM
Other info: An XDA thread compiling the same drivers - http://forum.xda-developers.com/showthread.php?p=37548841
I don't know how to apply the drivers so I need to learn how to do so, I have ADB set up and have Noogie, CWM and NookManager .img also.
Any other info needed i will provide

Just a quick comment:
Host mode on the Nook currently uses a lot of power.
Something like >100mA in comparison to a usual 8 mA or so.
It's not been tracked down yet.
I can get you better figures for this later.
Presumably this is for some fixed install using hard-wired power?

No I'm actually just using it as it is; no hardware mods.
I have not used usb host enough to know the drain speed but while plugged in to a live ethernet yesterday, it drained seemingly quick.
This isn't a preventative issue though; my need to access the web on the nook via ethernet (no wifi dizziness) is urgent.
If i had to recharge every 10 mins e.g, this would be extremely hindering but still necessary.
Hard wiring may be desirable (maybe not if it's permanent), i haven't read any posts on it thus far.
I do have a powered hub etc if applicable, i dont know if it can charge as well as hosting from the usb.
Sam
Yes, you can USB host and charge.
I'd recommend a back-powering hub.
That way, if you want to throw a USB keyboard on it too, you can.
See: http://forum.xda-developers.com/showpost.php?p=22956658&postcount=103
Great, i'll give it a try
