[Q]Useful USB? - Acer Iconia A500

Because of the USB port, A500 could become more powerful. Now I just see it support the HID. But I see the keneral source, It should support more devices? True?

The problem though is drivers for the hardware. That's some roms here support the 3g modem and others don't. If we could compile the drivers into android friendly drivers, then theoretically yes, it could support more hardware-

[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????

Toshiba AC-100: 3G on USB?

Hi, I'm going to buy AC100 NO3G... can you tell me if it supports any 3G USB key? If yes, can you say which internet keys?
Thank you very much
I would recommend the UMTS built-in version, as it is not so much more expensive.
However, all USB hardware works as on any other Linux system, except some proprietary drivers are not available for ARM.

[Q] externally powered wifi adapter via otg for Backtrack

Greetings! I've been lurking on XDA for quite some time, and first I would like to give a big thank you to all the developers. I would never have purchased a Kindle Fire if I didn't have faith in your ability to unlock the hardware's true potential. You guys/gals rock.
Here's my question: I develop and troubleshoot municipal and commercial wired/wireless networks and I would really like to be able to use the KF with backtrack. I understand that OTG support under ICS is very close to being a reality, would it be possible to support an external wifi adapter via OTG?
Drawing power is the first problem that comes to mind, so my thought is to mod a USB OTG adapter to draw from an external DC source instead of the KF.
This could have some awesome potential if it could work. I'm willing to do whatever I can to make this happen, so if one of you veteran developers could set me on the right track to backtrack it would be greatly appreciated.
I'm no wifi/kernel expert but as far as i have understood it:
It should be possible if you get the right wifi modules to work. Android uses a modified wpa_supplicant, so even if you have linux wifi drivers for usb you would need to patch them to get it running. The current kernel does not have mac80211/cfg80211 modules compiled it, but i think that you probably would need them (i think they are in the kernel source, they are just not set yet). The current module for the tiwlan is proprietary and is also uses some strange ibCustomWifi as wrapper around WEXT, not sure if they also did some changes there.
If the 3.0 kernel boots we should anyhow change to a mac80211 wifi driver and also use wpa_supplicant 0.8 instead of 0.6 so your chances should be a lot better with the 3.0 kernel.
So it strongly depends if your external wifi adapter is very well supported for linux (or better for Android ....) und if we get otg running. (There might be some hidden problems to discover).
Sengwall,
There are several threads in the xda forums for similar projects on different devices that might be useful as the steps are basically the same (assuming that somebody gets OTG working). Here's one of them:

Thanks for the input...ill look and see if there has been success on other devices with the same board.... great suggestion.

[Q] Downgrading to 7, drivers compatibility

You will have to excuse me if this has already been asked and answered somewhere. But I'm really pissed off at the moment and could easily kill all the developers who worked on Windows 8. To cut long story short, Win8 has caused me a lot of problems and I wish to downgrade to win7. So here's my question. I have an Asus laptop which has drivers only for Windows 8 (I realized this too late). I'm wondering if I can run Win7 normally with generic drivers that are not laptop-specific?
Any helpful answer is greatly appreciated.

While I'm curious about these problems you mention, in actual answer to your question, it entirely depends on the hardware in your laptop. Stuff that Win7 supports natively with generic drivers, such as USB2, typical mice and keyboards, SATA HDDs and SSDs, and so on will work out of the box. Some components, such as the video card, will partially work with generic drivers but you'll want to download Win7 drivers for that hardware to get full features. Other hardware, such as USB3 ports, WiFi, and any sort of touchscreen, will almost certainly have Win7 drivers available but may not work at all until those drivers are installed (as the drivers probably won't be included in a standard Win7 install image). It's pretty unlikely that any of the hardware in the laptop will *only* have Win8 drivers, but you may have to go hunt down the correct drivers from non-Asus sites, or find older Asus laptops that have the same hardware but were supported with Win7.
Thank you for your answer. And about my problem. The instant I log in, windows automatically logs me out, as if it cannot start explorer.exe and userinit.exe. I tried EVERYTHING, check disk, reset, repair, I cannot enter safe mode as I need to log in to enable that (why oh why did they have to remove F8 on boot?). The only thing that's left is clean install. I never had such problems with Win7 and earlier versions.
Edit:
I'm curious about the difference between drivers for graphic card from asus' website and nvidia's website. Does Asus alter drivers in any way?

The drivers from NVidia will actually be BETTER than the ones from ASUS. The ASUS ones wont be updated as frequently. Otherwise the ones from ASUS are just NVidia's ones repackaged
I have never heard of your issue before though.
Actually, that depends... if the machine supports switchable graphics (say, Intel integrated as well as NVidia), you'll need the correct drivers to support that switching. Just installing the NVidia drivers will work, though, and it's true that they'll likely be more up to date.
NVidia's reference drivers for mobile devices also tend to be really buggy in my experience, though - things like preventing the computer from entering sleep or hibernate, or running the fan too much (even when not needed) and wasting battery life. They seem to be un-optimized for mobile machines, which OEMs sometimes fix for their specific models.

If you google a bit, you'll see quite a number of people having similar or same issues, as a matter of fact. And no solution for the problem except a fresh install.

Yes, that's my case. I have both Intel and NVidia. As far as I'm concerned, I don't mind not having regular updates, or updates whatsoever if the drivers are stable and working.
By the way, thanks to you I searched for older Asus' laptops with the same hardware with Win7 drivers and found one. So now I have pretty much everything of importance working (ethernet, wifi, graphics card, etc.), though most of the Asus' software doesn't work as it claims my laptop is not made by them. Silly laptop specific OS restrictions.

[INFO] OTG / USB Host

Oppo says that the hardware doesn't support OTG/USB host at all
the platform (APQ8064 SoC) does. don't remember/know what USB chipset this device uses
device hardware documentation
Last time I traced the kernel, it looks like the USB device tree isn't loaded at all in the kernel, so no OTG support... wonder if other people have had time to look at it

Tried it on my CyanogenMod build, no reaction. It is possible that it acts like Nexus 4, aka. the phone doesn't power the USB upstream (even if I saw some references to that in the kernel...), so if you enable USB OTG support, you'd need to power your USB device externally.

That seems to be a common issue for a lot of devices - The host SoC supports it, but they didn't bother to wire up the PMIC's boost converter.
There's a lot of code related to OTG in the kernel source, but I think it's all upstream CAF stuff. All of Oppo's changes to the USB drivers seem related to charging. (It's a little confusing, as there are a lot of functions with "otg" in the name that are doing lots of non-OTG-related stuff.)
I'm thinking of looking into adding/enabling ACA support for Nexus 4 (and maybe other devices too). There is an official standard for externally powered OTG adapters - they can even charge the phone! However 90% of the adapters on the market aren't compliant with this standard.

We don't know yet, but it looks like it'll only be possible for externally powered devices.
Ahh man...
So what you're saying is that dock thing with a usb port on it from Sony Ericsson might work but that's it?
Oppo product manager said they do not want to take the risk by adding OTG Find 5, I saw that post on Sina Weibo in China
has anyone tried stick mount from play store .....is it working? it requires root but
The device has basicly the same issue (missing 5V output) like the Nexus 4. With some modifications its at least possible to get a properly function with external powered usb devices.
Kernel is based on the work from Ziddey and Cyanogenmod Team:
http://www.oppoforums.com/threads/usb-otg-externally-powered-usb-otg.2083/
Does that mean that in order to get USB host to work you must power the device externally AND use a modified kernel?
