USB host

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.

[Q] DVB-T on Iconia A500 ?

Hi,
I have an usb dvb-t stick (of the family A867 of avermedia, the nano 3d), can you tell me where the drivers are installed in the honeycomb for the iconia a500?
When I it connect to the iconia, from the terminal typing the command smesg, I can see that it recognizes the device but does not have the drivers

What makes you think drivers exist? If there are Linux drivers available, you might be able to port them, but then what? You'll also need an app capable of decoding the data from the device, and tuning in to the needed frequencies. Such a thing doesn't exist on Android at the moment.

ok, thanks for reply

Drivers exist ! DVB-T is functioning on Archos 101 (Froyo). They have an app that scans (livetv.apk as i remember well) the dongle. Look for internetadresses at the thread i opened a week ago. Unfortunately í'm not able to adapt the existent drivers for our tablet. The last driver i wrote was to connect a Teletype to a Z80 processor so now you now i'm a digital dinosaurus.

My "Cinery T USB XE" works on my Acer Iconia A210.
I have done a channel scan with droidTV.apk. Found channels, but have a very high error rate, so it*s don't see anything.
Is any one working on an app for DVB ? Maybe someone can tell how to crosscompile an binary? Or maybe can tell me how to configure toolchain paths for compiling successfull????

Cheapo 10" Tablet, your recommendations. Will want to clean install OS

Hi, I am interested in buying a cheapo windows 8.1 with bing tablet and need help picking one from ebay. I will want to format and clean OS install
Can I have a recommendation on a model.. Budget no more than $300 Australia Dollars or around the 240 US.$
I am an IT techie so I know the ins and outs of installing os onto laptops and desktops.. i inderstand BIOS's and understand technology fairly well.
Tho never actually used a portable windows device. Do most of these devices have bios like a desktop? Startup selection hdd vs usb hdd etc?
I will want to end up deleting the recovery... Delete the android os if included and install 8.1 with bing clean, or eventually purchase a 8.1/10 pro for business use.
If I can have some info on whats good and whats not, i would really appreciate that.

Chuwi Vi10 64GB + Keyboard around $255 shipped to Australia from Gearbest.com
Cheapest one I could find. I myself is wanting this tablet, but might want to wait till Cherry Trail tablets are out.
Currently have a Voyo A1 Mini 8" Tablet. Win10 TP, removed android.

can you tell me how you went about doing this?
do these hand helds operate like a computer? same sort of bios settings?
how do you enter bios on your model?
is it anything like changing roms for mobile phones like samsung galaxy for example where you need USB cable connected and download roms onto it? or it is actually a fairly simple operation?
you can install drivers? where did you source them from?
any other comments would be great...

I look into it as a handheld portable PC.
UEFI is what most Windows Tablet is using.
Installation, operation and use is exactly as you would expect it as with other Windows PCs, limited to its own hardware, and/or the OS you put on it. Search Ubuntu/Linux on chinese tablets.
You should do your assignments more before delving into this.
On a personal level, I can see myself selling my i3 15.6" laptop (I only retro game, and used mainly for Java, Visual Studios and non-hardware heavy) and my Voyo A1 Mini tablet, to get a good 2-in-1 PC. I need/want a more compact portable PC. And same as you, I've got a VERY limited budget.
To share to you my current requirements (deal-breakers if not met), and must not be lower/missing, to completely replace the said above PCs:
1. 64GB internal capacity (eMMC 5.0, better yet SSD) (higher capacity will be more than welcome)
2. HDMI output
3. Dock-in Keyboard supported (hate bluetooth keyboards)
4. At least 1 FULL USB slot (hoping a USB C tablet will be released soon)
5. A dedicated power input socket
6. Have decided to wait for Cherry Trail CPUs (hoping to be released end of September to holiday season)
7. Decent capacity for battery
8. 2GB Ram for an x86 OS (4GB on x64 OS) (more is more than welcome)
Optional:
Keyboard dock to have output sockets too (usb), built-in battery. similar to Asus T100. Hopefully newer tablets will have full x64 OSes.
Still.. to each their own, on how they'll be using the device/s.

How to setup wifi adapter to sm-t350

How can i setup my TL-WN722N to my Samsung galaxy tab a??? I found things online about having to change the kernel, I've been able to extract my kernel from my boot.img file but as far as how to edit it I have no idea what to do. If I can't do it myself with help of the forum I'm willing to pay sum1 to do it for me I can send the kernel to any1 interested.

For what reason would you want to use an external WiFi adapter over the inbuilt wifi?

For several reasons extended range for 1 but also use with kali nethunter and kali in Linux deploy for monitor mode to packet capture . Only on networks I have permission to do so with of course . Really I would be using it as a learning tool. I already have a pc running kali n Virtual box no problems there. But would prefer the more mobile aspect of using with my tablet. Being able to practice on the go without lugging around a laptop just seems much better. And you know it sounds totally kewl I'm sure there are plenty of other tab a users who would want a kernel with external wifi support as well.

Your best bet is to try running something like Linux deploy on your Tab, and connecting the WiFi adapter to it with a USB-OTG cable. (Researching the adapter model says its USB compatible) I can't speak for running Linux deploy on our Tab though, I've never tried it. Other than range and possible pen testing, you shouldn't see any advantage over simply using the native WiFi on a 5ghz network. You'll be limited by the internal write speed anyhow. Judging by TWRP's back up rate, its something around 40-50mb/sec.

Already have kali on linux deploy. Problem is the hardware for the adapter has to be built into android kernel in order to function. Have a pc with ubuntu i could use to modify the kernel problem is i dont know how to do that.

I'll see if I can turn up any info. I have a vested interest in this. I want get USB tethering running. I'd imagine the changes are going to be similar.

Question [Question] Android as Host Controller

Hey All,
5+ years experience 3D printing.
Some rooting / ROM android experience.
Okay so first of all I am going to explain the situation then ask the question.
Raspberry Pi and other SBCs are hard to come by or very expensive as of currently posting.
I have serveral RPi that I use, one being an 8gb RPi4 that runs Fluidd/Klipper for three of my printers.
Due to this RPi shortage I have looked into alternatives that are low powered ARM systems. I have considered cheap android TVs that I could run armbian on.
I have a friend that wants to run klipper on his printer but he doesn't have a RPi.
He has a spare android phone he is willing to use it as the host controller.
To investigate, I installed Octo4a on a spare phone (ZTE ZMax Pro MetroPCS). I installed klipper with a script through bash and installed the octoklipper plugin.
-Could not connect it to a printer / unsure if the klipper version on the MCU was the same as the one on the android.
-Getting tons of printer.cfg errors.
According to Octo4a you cannot flash the klipper firmware to the MCU via the android phone, thus another host must flash that firmware to the board.
I understand for long term use one would need a y-splitter OTG cable.
Even more long term to have a 3.7V source to replace the battery...
After doing some more research I found a korean guy on youtube running klipper on android via a rooted phone and a custom ROM and kernel.
After even more thought I was considering running a docker container on the android. Fluidd has an official docker container for fluidd/moonraker/klipper.
TL;DR
I am trying to run klipper on android so I can help my friend run klipper on android for his 3d printer.
Can anyone with experience help me?
Should I root the phone and try using termux and run alpine linux?
Should I learn docker and try to go that route?
Should I suggest a low cost android tv box and run armbian on it?
Is this a little too much to ask / complicated request ?
Can anyone point me in the right direction ?
I really feel like this is doable but I can't quite figure it out due to lack of experience with android development and docker.
Thank you to anyone who helps.

From my experience using octo4a on Android: you need good hardware, not any old phone, otherwise it's slow. And also without root running scripts can be cumbersome of if you don't have access to the system like on RPi...

take her home Mimi

thank you all man I'm going to leave okay I got I got everything
