Hi!
In which way android "communicates" with the hardware?
Are kernel drivers used or is communication done directly via i2c?

Will my huawei e1550 work under android?
I see that some other Adroid devices (china tablet pc like Zenithink and other) have the software, which can config internet connections.
Will Gen8 init this device?

For now, no. Unless Huawei or 3rd party develop driver for it.
My E1550 now also collecting dust coz i'm using 101 most of the time rather than laptop.
If i understand, we need root access to add 3rd party driver? Or there uis no way to compile driver?
This would be quite interesting if it would work.
Would this also enable call/sms functionalities?
I have an AT&T Laptop Connect Dongle which does not work. I have been able to bluetooth tether using PAN. I would rather use adhoc, i haven't found a way yet.
I prefer Archos to improve the stabilities of his 2.2 firmware first before adding more "new" features.
3G dongles
Correct me if I'm wrong, but as far as I was able to digg around, it seems that USB host mode (wich is already in Archos), __usbserial.ko__, and adeqaute parts of devfs rules, are only three really necessary things that are needed on any linux, for USB 3G dongles to get properly recognized (at least Huawei ones).
rest of the things regarding "dial-up" a 3G connection, are done with commands from ppp package (should be in froyo), can be done from shell (busysbox __should__ be sufficient) for a start.
usb_modeswitch package is needed also, but only for the modems that are USB composites with virtual CD-ROM and/or MMC card reader (like mine E1552) in order to switch them to a serial mode (because their are detected as mass-storage initialy). For a start, this can be overcomed by sending adequate AT command's to dongle, that disable dongle's virtual CD-ROM and/or MMC card reader, from some windows machine prior to experimenting with dongle on linux/archos (setting is saved on dongle - you only need to do it once).
Since I still don't have my A101 (should receive it beggining of 2011), can someone tell me from kernel .config file is USB serial support compiled in archos kernel, and if not can we compile it as a additional module (like archos unionfs/ntfs modules is see in other thread) ?
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?
I have an Ainol Novo 7 Paladin tablet running android ICS 4.0.3 (rooted) that I want to use in one of my projects. And I need it to communicate with an arduino - one with FTDI or prolific PL2303 serial interface. Now I know that the Paladin should work as an USB host but I need something more. I need an high level Java library that can use this serial interface. I've worked with rxtx on a desktop machine before and that is the most complicated that I would like to get. The main reason is that I simply don't have enough knowledge to write myself an serial driver. I just need a simple character based two way communication.
I've found this http://slickdevlabs.com/slick-usb-2-serial-library/ but I don't think that it will work for me - at least the test application doesn't since the Paladin has an Ingenic JZ4770 CPU that isn't ARM based. And the second problem - I don't like the price.
So I have made an USB OTG cable that is working - I can connect a mouse, keyboard, usb drive,... . Getting the serial interfaces working is another problem. When I plug the arduino with an PL-2303 controller to the tablet I get this (with dmesg):
Code:
USB AS HOST MODE
...
hub 1-0:1.0: unable to enumerate USB device on port 1
usb 1-1: new full speed USB device number 82 using musb-hdrc
usb 1-1: device v067b p2303 is not supported
we are entering usb_match_id!!!!!
Simillar with the arduino with FTDI controller.
As far as I know android should have the drivers for the PL-2303 and FTDI chips included. So any ideas?
I am in need of some feedback.
I would like to use my springboard with a proprietary usb based device similar to an arduino, but the stock 4.0.3 rom USB OTG capabilities only allow for things like usb thumb drives and keyboards. the usb device i am using doesn't show up as available to android. using an app like "USB Host Diagnostics" claims that the android API has support, and classes are found, but device was not detected. it does also claim there is kernel support and the device was detected at the kernel/linux level. therefore the stock ICS appears to have OS support, but not 3rd party support. I am looking to see if any of the ICS or JB roms from others support USB OTG at the android level, not just the OS level.
thanks.
For proprietary device you need a driver I guess.

I know that it requires some sort of driver support, but not specific drivers for the device. I am currently developing the code for it on my Acer a500 with no problem, and it didn't require anything special/extra. the original Honeycomb and the stock ICS both see the device fine.
I am working on a project that requires me to setup a windows pc as an accessory in order to communicate with an android phone via a USB cable. After studying the ADK(ANDROID DEVELOPMENT KIT), it seems that you must have micro-controllers endorsed by google which supports aoap(android open accessory protocol) to communicate with the Android phone. However, my project requires me to establish communication between PC and ANDROID via a USB cable without a micro controller. Also i would like to know how to program such an application,what software should i use,what languages do i need to know? What should be step 1?.
