how detect an external usb keyboard

Hi,
my device is an Archos 7 home tablet based on Android 1.5. I connect
an external usb keyboard by means of a microusb host adapter.
I am developing a virtual keyboard for disabled users and I am writing
a scan mode for this input method; the virtual keyboard should be
detect a keypress from the external keyboard. How can I do it?
I am trying to create a onkeylistener, but it does not work.
Best regards,
Pinguinodaddy

I'm pretty sure you cant use a keyboard. Android doesnt have usb host support.

No, I sure that Android 1.5 has the usb host support. If I connect an external usb keyboard by means of a microusb adapter, this keyboard works perfectly.
I am having some problems when I try to detect an external keypress from my apps. How can I resolve the issue?
Best regards.

Wireless keyboard (not bluetooth) works!

Ever since I saw the Host enabled USB port hack via Tiamat I've been wondering if my wireless Logitech keyboard via Unify would work and how awesome it eventually will be...today I am happy to say that it is confirmed!
I've just received my host cable and as soon as I pluged the unify usb dongle in the port, the keyboard worked natively, no driver or anything else...it could be just me, but I think it's pretty freaken awesome! even ctrl+T opens a new tab...
that is all, k thx for reading

That is cool. Not sure that they make too many portable mini 2.4 keyboard though.

Not sure about mini keyboard selections, but this implies any keyboard that would work natively on your pc should work fine with the xoom with usb host enabled.
EDIT: found both efo and logitech make quite small keyboards for google tv, which would work also for the xoom.

Forgot to mention, I've noticed the xoom restarting more than once while i have the host cable pluged in and the usb dongle, Im not sure this is a result of 1. Tiamat 1.3.0 2. Usb Host cable 3. Unify keyboard drawing too much power?

Some time ago I posted a similar experience when I connected a USB keyboard to the OTG cable. It might be linked to the keyboard. I have not had an HDD connected for more than a few minutes so I should try that.

random Q....tiaman 1.1.6 and 1.3.0 already incorporated the host mode hack?

That was the reason for me to load the Tiamat 1.1.6 kernel. To my knowledge it's still in 1.3.0. You might also want to check the guide enable mounting of NTFS volumes!

I also have a wireless logitech. I bought an OTG microusb->usb and it worked without any modifications (no tiamat, etc)

any chance a wireless (non BT) mouse would work this way?

Highly unlikely. Even a generic mouse will require some kind of drivers and a pointer is not implemented routinely AFAIK.

Awesome thanks for the reply

Using mice and USB keyboards on Note

The GNote has the ability to act as a USB host, which allows one to attach a flash drive directly to the Note as external storage.
Can we expect devs on the forum to develop USB drivers so we might use other peripherals such as keyboards and mice on the GNote?
I come from a Notion Ink Adam tablet which runs Froyo and was able to work with plug and play USB keyboards and mice.
Would be a very nice feature to hafe on the GNote.

I don't have the NOTE yet, but on my present device I can attach a USB Keyboard directly to it and it works. I don't need any driver.
Did you test it before opening this thread?
Please confirm
Remark: And same for mouse!

My USB keyboard works fine
Tried several mice and one worked, most didn't (not sure the model name of the one that did, it as a Logitech, will be back in the store later this week and confirm).

http://www.youtube.com/watch?v=QYlfuNIGQsw bluetooth mouse works too

Yep BT keyboard mouse work also, amongst other things:

using usb mouse on note.
so you guys are saying that one can use a usb mouse on the note. i guess first you need an adapator or an usb mouse with a micro plug, then just plug and go.

I tested out my razer orochi BT mouse and it worked fine. Don't have any use for it yet until I get a small BT keyboard I can use.

Hi Pere,
To be honest. I read a review which stated that in practice with the OTG USB adapter only flashdrives and externally powered hard drives seemed to work and that the drivers for keyboards and mice would be needed for them to work.
This did not stop me from ordering the adapter, which still has to be delivered. Will obviously test myself once it arrives.
Would be delighted if one can plug in any USB keyboard.
Thanks for clearing it up.

That's the GSMarena review and they are quite incorrect. My USB keyboard works perfectly, as did the USB mouse I tried instore. You will of course need a USB OTG adapter.

Nice!! Thank you.
Two more questions, one of them for people using not standard English keyboard ( French, Spanish and so on...) does the keys layout meet with the written characters? I mean: symbols as ;/"? are in different keys? or does they match with the written ones?
The second question or test: Can we use a Host USB to connect together both keyboard and mouse simultaneously to the note!?
Who will be the first in test?
Thanks in advance

Good question! I would like if one could answer that as well.
I guess it would require a OTG usb cable + USB hub. Does the Note support for a USB hube? I mean, would the USB host in the Note allow that?
Also, if it works with an USB hub, then I guess you would be able to both output screen to hdmi, charge and use USB keyboard/mouse at the same time?

An Italian coleague has already answered the USB hub question with this video: And yes, we can!
Regarding the simultaneous connection of mouse, keyboard and HDMI would be great but I'm afraid that there are technical reasons to doubt that it's possible...
What about the special signs question? Any idea?

I am super curious about what showed after 4:00 is that windows or some theme looks like windows?
If Note can operate windows that would be wonderful!

Could somebody explain what exactly is a 'USB OTG Cable' ?
Is it just a cable with a male micro usb plug at one end, and female std. USB plug at the other end ?
Or it needs some magic electronic add-on inside ?
Thanx in advance

All PS\2 keyboards and mouses works great too.

If you use a USB keyboard, does that mean you can't connect it to a monitor as well? You need a bluetooth keyboard to do NZtechfreak's setup, correct?

[Q] micro usb port hosting

Basically, I just want to know if you can use a keyboard with it that has a micro USB plug. Thanks in advance if you can help me out.

I believe the manual says it supports USB input devices. Mouse and keyboard should work fine.

Great! Thank you for the speedy answer.

Yes you definitly can
Nexus 7 Manual said:
You can connect a keyboard, mouse, or even a joystick or other input device to your tablet via USB or Bluetooth and use it just as you would with a PC.
You may need an adapter to connect the keyboard or other device to your tablet's USB port. To connect more than one USB Device at the same time, usa a powered USB hub to reduce the drain on your tablet's battery.

Can heartily recommend the Apple Keyboard actually, it pairs up nicely to my Galaxy Tab. That plus a BT mouse and I'm gtg for support issues if I'm out and about. USB connectivity would be good, but the BT solution for keyboards opens up a fair few decent choices. Not tried other keyboards, but the Apple one works as it's so thin to slip in a light bag.

[Q] sm- t530nu MHL/screen mirroring

Hey Everyone,
I just recently purchased a SM-t530nu,apple magic trackpad, apple wireless keyboard and a AUVIO Universal MHL Adapter. My goal was to be able to attach it to my HDTV and sit back and browse with my trackpad and keyboard. The keyboard and trackpad work great, no problems there. The issue i'm having is the MHL adapter does not seem to work for me. It has a micro USB plus and a "s" adapter that says it is for a Samsung galaxy s 3. I have tried it with and without the adapter and no luck. From the information I have read this model does support MHL. Is it simply the AUVIO one I am using or have I misread and this infact DOESNT support the MHL feature. It is the tab 4 10.1" as I am sure most of you know from the model number. Has anyone successfully used a MHL adapter to connect this model with a TV? If so could you possible share a link/ model number of the one I will need to make it work? Im also curious about the screen mirroring feature i've noticed in my settings. What would be the CHEAPEST device available to use this feature? Thanks in advance for the help everyone!

USB HOST is not supported yet, so nothing besides the USB Charging/Data cable will work
