hi to all, I'm not sure if I presented my problem well .. I have a problem with a simple idea but in solving it complex, I have two otg devices to connect to a tablet, one and an easycap, and one is a uvc for drones, the devices are detected but do not give video output because the drivers that are in / sys / bus / usb / driver are missing I tried to copy them from an android device where they work, but I have no read permissions on those folders. The question is senplice .. I know that those folders are part of the kernel I can decompile the kernel, but I don't know how to find and implement such drivers, if anyone knows something about it? Thanks

There are some people in this forum that have got success instaling ubuntu on Folio. I've got too.
Now i have a great question !!
Are our folios fully driver installed ??
For example, in my folio with ubuntu, i can't use bluetooth or i can't heard any sound because it doesn't run, or also i can't adjust brightness...
I have searched lot of pages and i haven't got success....
This thread is created for people who knows how install this kind of drivers can help us to make us happy !!
If you discovered how to install any kind of driver... or things for optimize ubuntu and make it more quickly please, post it !!
Also would be insteresting if people got success installing programs on our ARM architecture device like Dropbox, Foxit reader, Wine compatibility layer... that are based on i386 and AMD architectures post a how to do it.
Thanks in advance for all people that make that possible.
Hi,
I am working on sound driver. Just trying to find specs as running android do not give enough informations.
I will also try to integrate accelerated drivers as in AC100 build (but system may be unstable...)
Akta
When I installed Linux on my netbook, I haven't got bluetooth, go to software manager(ubuntu market) and search for bluetooth(drivers). May this help you
I'm working on sound too...
I guess there is an GPIO Chip inside the Folio, which manages sound in-/outputs..
I dont know whether the bluetooth and screen brightness are also part of it...
The GPIO has many inputs and outputs, but these are not fix...
So you have to build/run a program which tells them to be an output or input and what they have to do...
I ported the mach-tegra tree and the sound/soc/tegra tree from android-kernel-source to the folio source..
After that I ran nvrm_daemon in a chroot..
For that you'll have to do the following steps:
1. Create a new folder whereever you want (for me /home/ubuntu/Desktop/chroot)
2. mount /dev/mmcbkl0p1 and copy the bin & lib folders into your directory
3. create a folder called system inside your folder and move the lib folder into it
4. create the folders dev and proc
5. open a shell and cd to your directory
6. $ mount -o bind /dev dev/
7. $ mount -t proc /proc proc/
8. chroot ./ /bin/sh
9. nvrm_daemon
You should better run chroot/nvrm_daemon from a ssh shell on your laptop because sometimes the screen gets black, because of segmentation fault..
Then you can take a look @ dmesg..
There are some outputs given by nvrm_daemon.. Also for GPIO but they failed to change some pins because they are already in use..
And I guess thats the problem!
I also tested whats happening when the nvrm_daemon is not starting when android boots.
I removed it from the ramdisk.
After that the folio wasn't starting anymore...
Only after I started nvrm_daemon manually via adb shell the boot screen appers and the window manager starts..
So everything depends on the nvrm_daemon!
I hope you'll more lucky than me and findout why the nvrm_daemon is not starting correctly!
Regards
Thanks for the info.
Will look at that to begin with
Akta
I there, I have contacted Atheros to know which bluetooth chip is in our folio and they replied me that is 3011 or 3012 depending on the version.
I hope this helps to get bluetooth working early. I will try using ndiswrapper to install windows driver after the biggest brick ever!!!
I found the drivers for the gpu
I've gotten through the forums trimslice computer graphics chip drivers Tegra2
To download them here:
Code:
trimslice.com/download/drivers/nvidia-drivers.18.0004.tar.bz2
These drivers are valid for Debian and Ubuntu Maverick.
However, you must edit xorg.conf to make them work properly with the folio 100.
If someone can correctly configure xorg.conf. I would appreciate it also put him in these forums. Thanks
To install the drivers simply must enter the terminal from ubuntu and type the following commands:
Code:
cd /
sudo tar -jxf nvidia-drivers.18.0004.tar.bz2

Hey, I have installed this drivers and now I can't boot ubuntu !! Can you help me ? I send you a mp with my e-mail, we can speak on google talk chat i'm spanish !
thx !!
I had said before, it is necessary to create an xorg.conf file that is compatible with
toshiba screen folio 100.
It is the only way to have graphics acceleration.
Funny how nobody was interested in compiling the kernel with support for
ALSA (and there have been some drivers called tegra) But if you do not work
we can always choose to have sound through USB since.
no news ? aneybody have graphics acceleration ?
up please!!!
please why nobody reply ?
Is there a list of functions that can be used with the GTab USB? For example: can I mount a digital camera as a USB drive?
Pretty much all storage devices work. People have had success with 3g usb adapter. Mouse and keyboard also work. I haven't tried printer yet.
Has any research been done with usb wifi adapters? I've searched but with no success as I'm sure the issue would be driver related.
The kernel controls what can and cannot be used via USB first.. If there is kernel support for your do-dad, you're good to go at least for the first step... after that, the rest of the Android framework needs to allow you to do something useful with the thing, which may or may not stop it from helping... or may require apps, or additional libraries, or pixie dust.
Right out of the box, if it looks like a HID (keyboard/mouse) or storage, something encouraging will happen on most of the g-tab roms, even the stock rom. If its storage but a format that's not supported by your kernel, you may need additional modules, or it may never work.
Everything else, who knows. Use a custom kernel, and get the source, and build one that supports what you want. Check for linux support - if its supported in linux, odds are way way better...
user mode usb driver support?
I would like to write a "virtual Control Panel" application to communicate with a propriatery device via USB. Under Windows XP, I wrote a device driver, DLL and C++ application.
Now I am sure the linux kernel does not support the proprietary protocol of my device. However I understand that some linux systems support user mode device drivers for USB devices.
Is this the case with Android 2.3?
If so, can a user mode device driver be written with the Android SDK?
Hello, I would like to ask you for your help.
I have a digital multimeter VA18B with USB output. The output is actually optically separated USB to RS232 adapter. Link:
http://www.mastech.com.cn/html/en/products-va18b.htm
Since I have a phone with USB host support (Samsung Galaxy Nexus - latest AOKP), I had an idea that I could use it to record data from the multimeter. But I have no experience with Android software development.
The device itself seems to be supported on Android, because I can connect it and read some rubbish characters in intervals of measurement with this app:
https://play.google.com/store/apps/details?id=slickdevlabs.apps.usbtoserialterm
PC Drivers for this multimeter are very limited - only Windows up to XP. Because I primarily use Windows 7, I already use Linux and this script with my multimeter:
http://multimeter.schewe.com/
Source code is in the zip on that site, and also here: http://pastebin.com/iqKW3iFa
It is written in Perl, works on Linux and Android is "Linux". So my first thought was that it could probably be easy to use the same script on Android. I tried to find how to run Perl scripts on Android and found sl4a:
http://code.google.com/p/android-scripting/
After installing the Perl interpreter it can run my script but it doesn't work. The fact that I don't know Perl doesn't make it easier. The script fails to find the device. I thought it is caused by different naming on Android so I substituted the "/dev/ttyUSB0" thing by "/dev/bus/usb/001/033" which I have found in the already mentioned serial adapter app. But it still doesn't work. In both cases it ends complaining about "Can't open device ...".
Because of my level of knowledge I have no idea what to do next.
1) Can you please help me somehow?
2) Next step after making it work will be saving the data to file. That is another problem I would really appreciate your help with, because I did it just by output redirection in Linux and have no idea how to do it here.
I hope someone took the time to read this and perhaps will try to help me. Thank you very much.

Greetings!
I Have created a gamelayout for my ps2 usb adapter controller, the problem is that it doesn't get detected in Android, it's detected under linux (I attach some images) and the .kl file -It's inside "Vendor_12bd_Product_e002.zip" yes it's codified in UNIX, not MAC or DOS-.
I followed the tutorial from here.
I don't know if this has to anything but my tablet is a chinese Pipo S1 dual core Rockhip 1.6ghz gpu mali 400 with the stock software -Jellybean 4.1.1-.
As I stated, the controller gets detected, but the problem is that I want it to get detected as it should -Since it has plug for 2 usb controllers- in "Android" not in "Linux", hence, the .kl I used is not being detected and doesn't apply my mapping.
Any ideas?
PS: I already did the changes for r w r r, I used the terminal too -command ls -l /system/usr/keylayout- (image attached) Do I need to declare this new Keylayout somewhere?
Edit: The new configuration does get dettected though, the device isn't is because the modules are lacking due to the kernel source is not released and haven't compiled the .ko for generic gamepads
So finally is the Customised layout working?? If yes please let me know how?? Because for me it's not working.
Yes for games with native support, I havn't been able to make it work with USB Joystick center due to the lack of modules for generic gamepads
Hi folks!
I need the OTG/USB Host function on my Jiayu G3. Normally it doesn't support it..
So I did i lot of research and tests at "how i can enable it" and found some information:
1. some things point to it, like the libusbhost.so in /system/lib
2. all 5 pins of the usb slot are connected to a chip (this says nothing, i know)
3. i have found a pdf, which says that otg is possible on mt6575-77 (found on github)
So my question, has anybody get otg/usb host get enabled on Jiayu G3 oder m65xx phones? OR is anybody there who want the same like me and helps me to make it possible?
OTG unlock
Hi
I have a similar problem with my Jiayu G3s (MTK6589T).
For most USB devices it does not react but i hope there is a chance to make it work.
I do not know if it si trustworthy but according to USB OTG Checker my device supports USB OTG.
When i insert one of my USB flash drives i can find sdcard1 folder (total commander) . It is empty but it reacts.
Can anybody please help or just explain what is the problem. Thank you

Hi there,
I think I have a possible solution for this case.
Many USB cables are not correct to link with computer. I have two cables, one of Jiayu and other (more thin) brought in a chinese store. The cable brought in chinese store don't work to link with computer.
I hope this information was useful.
Any updates?

This might help. Using an apk it is possible to make it work, IF kernel supports it. Don't know if phone has hardware support though...
I've read here that you should connect the ID pin to a pull-down 150k resistor, then to GND.
