I was wondering if anyone has experience in Virtual Laser key boards such as i-Techs VKB?
http://www.amazon.com/iTech-Bluetooth-Virtual-Keyboard/dp/B00142C4O8
If so, are they compatible with our phones?
I am slowly moving towards using my phone as a full mobile PC. I would like to be as productive as possible and having a full size key board would be monumental... especially when editing documents. Sure, a laptop would be the best bet but this is the future.
As a side note, I would also like to note that this is why the iPad is a step back. Technology should be getting smaller, not bigger. You can see this with the invention of micro-projectors (google "Sixth Sense Project") or the paper-thin, clear, flexible LCD displays that are emerging. I don't want to load around some cumbersome device like the iPad or even a netbook. Smart phones are the future!
/rant
Anyway, if the laser keyboard is not compatible can someone point me in the right direction for any type of key board... preferably one that rolls up or something.
Thanks!
Found this that should work for you:

I see no reason why it would not work. Does our phone support a normal bluetooth keyboard?
Those keyboard are not great. They have a hard time keeping track of everything.
So even if you get it working, it will only kinda sorta work.
...Come to think of it, I'm going to try to sync a bluetooth keyboard we have in the shop right now.
Edit: Dell has neglected to give me the passkey to pair the keyboard. No dice.
Dell won't give you the pass key? Shouldn't it be a set standard for that model? I figured it would be on the website of the manufacturer under the support section.

I'm trying to use a Model Number: Y-RAQ-DEL2 keyboard.
http://support.dell.com/support/edocs/acc/P109356/en/index.htm
It comes with a reciever which pair it automatically to PC's. It can also be paired with laptops that have built in modules because the computers generates the Passkey and you eneter it on the Keyboard.
Our phones, however, don't generate one but instead ask for the Keyboard Passkey itself.
I chatted with Dell to get it, they told me to call wireless tech support. I called wireless tech support and they said the passkey has to be "0000". This does not work, however. The guy was an idiot. He was obviously reading off of a screen. There must be a shared code between the Dell BT reciever and the Keyboard that I can find use to pair the device.
Ugh.
It won't work. Even if you get it to pair, no current ROM or kernel known to exist as of this moment supports HID, and the commercial BT keyboard driver in Market (which supports SPP) doesn't work on the Hero.
As far as the PIN goes (when/if it ever becomes possible to use a BT keyboard on our phones), try this:
* Make the keyboard discoverable
* Tell the phone to scan
* When the phone finds the keyboard, try setting the PIN on the keyboard by pressing 4 digit keys then enter/return. That seems to be the way most of them work.
Unlike mice and gamepads, most (newer) keyboards WON'T allow you to pair as 0000 due to the risk of password interception.
if you are looking to go completely remote, i would advice waiting for the evo. snapdragon+gi.s.+a sd card and hdmi connectivity and whats sure to be our native sense experience in a fully functioning 2.1 playing ground that will have more than enuff support or what should be simple. things such as bt (...AND THE KICKSTAND) i think it will be your most likely option to suceed. good luck, i like my laptop.
Update: it turns out, there IS a driver to use bluetooth HID keyboards with Android -- BlueInput (teksoftco.com). Unsurprisingly, it doesn't work (yet) on the Hero, either
This has gotten me wondering... Has anyone figured out WHY nothing Bluetooth-related besides audio seems to work on the Hero (compared to other Android phones that don't seem to be similarly-afflicted)?
Is it a case of distros like DamageControl having kernels with BlueZ 3.x compiled in when apps like BlueInput(HID) and KeyPro(SPP) need 4.x, or vice-versa?
Has anyone with the background knowledge necessary to build a 2.6.29 Hero kernel from scratch and troubleshoot bluetooth problems even looked at the way the kernel is getting built for distros like DamageControl? It seems like right now, nobody even knows whether this is something as trivial as a bad option at build time, or a problem that's huge and hopeless.
Sigh. It's times like this that I really hate Sprint for not letting us have R-UIM cards. I seriously think SIM cards are a major part of the reason why we (CDMA users) seem to have so many kernel-level problems that GSM Android users don't. They can just swap SIMs, and experiment all weekend if they like without metaphorically leaving their phones "off the hook" in the meantime.
I am betting those features where compiled out of our kernel. It should be easy to put them back in but then the question is will it work with the hardware... and we all know from the camera that that isn't a given.

Hmmm. Has anyone ever tried taking a distro like DamageControl and using it with a scratch-built kernel known to have been compiled with everything BlueZ-related included and enabled? From the research I've done, it looks like we kind of have a catch-22 situation:
* All of the popular 2.1 distros seem to be using the same signed kernel. If that kernel's bluetooth support is dysfunctional, everything that relies on it for bluetooth will be dysfunctional as well.
* In theory, AOSP should be easy to experiment with bluetooth on... but NONE of the AOSP builds seem to really support bluetooth at all. At least, more than maybe being able to limp along with handsfree+headset mono. It seems to be kind of a vicious cycle -- most of the support apps needed to implement bluetooth and make it work aren't opensource, so the leaders (in a very oldschool Debian-like way) want nothing to do with them, even if it means doing without it entirely in the meantime. But since there are no ripped apps to bootstrap bluetooth support with until replacements can be written, nobody has any real incentive to work on tweaking the kernel to make them work... and since there's no real bluetooth support overall, anyone who really CARES about bluetooth (and would otherwise be the most motivated to work on improving it) shows up, looks around, and runs for the door. Oh, and the fact that even AOSP still has to deal with mystery binary blobs, because most of the HeroC's actual hardware is itself proprietary to Qualcomm and unavailable to peons like us (who merely own a phone that uses their chips).
I really wish I knew enough about both Bluetooth and the Linux kernel in general to try troubleshooting it myself, but realistically I'm still a long way from achieving that goal. I've learned a lot over the past month, but so far the only visible light in the tunnel is coming from the phone's backlight ;-)
Htc has not released source for the .29 kernel, so no one can really modify it. Maybe the .27 in the overclocked roms if you could convince a dev to help out.

Oh god, I completely forgot about that. We don't actually have the actual 2.6.29 source yet. I got so caught up in the 2.1 celebrations a month or so ago that I totally forgot about that important little detail
here is a 1.5 kernel that says it has usb hosting. But requires doing a little extra for the drivers.
http://forum.androidcentral.com/51730-post2.html
This is a very much work in progress. And is on hold until a breakthrough happens or DerArtem responds to my PM with some info.
First off, credits:
ejhart - All of the development is basically from him. He compiled the sierra.ko for Android which was the big step. Took me through all the steps and has been the main force behind this.
Pershoot - Thank you so much for your kernel and your hard work. Your inclusion of pppd and usbserial helped so much.
Sierra Wireless - Your USB dongle started this? No, but seriously, the Linux support of their modems helped get the device accessible from terminal and may get it to work fully eventually.
DerArtem - Your Folio work on this same thing helped. http://forum.xda-developers.com/showthread.php?t=914350 (UMTS/3G Support on Toshiba Folio)
(Random thanks)
Cyanogen - For CM and all he's done for ROMs in general.
Speed Software - Root Explorer is the most useful app.
Jack Palevich - Terminal Emulator makes this work.
PinkVenture - GScript Lite makes my boot easier.
Current Status
Dongle can be accessed from Android.
pppd functions do not throw errors.
lsmod reveals Sierra device as live.
dmesg shows it loading from ttyUSB0, ttyUSB1, ttyUSB2, and ttyUSB3.
All work is using CM7.
How to get your tablet here
1. Download and install Pershoot's kernel from here.
2. Download the attached files: sierra.ko.zip and ppp.zip
3. Extract sierra.ko and the ppp folder and then copy them to sdcard or internal storage.
4. Download Root Explorer (paid app), Terminal Emulator (free), and GScript Lite (free).
5. Use Root Explorer to copy sierra.ko to /system/lib/modules/ (needs to be mounted R/W). Then copy all the files within ppp (ip-up.local, ip-down.local, and peers folder) to /etc/ppp/
6. Open Terminal Emulator, execute "su" (allow it to use Super User), execute "insmod /system/lib/modules/sierra.ko" (no quotes on any command)
7. If no error is thrown you are where you should be. In Teminal Emulator, execute "lsmod" (no quotes). It should display something like "sierra 11378 0 - Live 0xbf000000"
8. This step is optional: Open GScript Lite, press Menu, Add Script, in the Name field put whatever you want, in the Script field type the same command as above, "insmod /system/lib/modules/sierra.ko" (no quotes)
9. In Terminal Emulator, (as su) execute "pppd call cdma". If no errors, it should be at the same point I am. Congratulations!
Current Issues
1. Modem doesn't act as data connection.
2. No software support for modem.
3. Needs device specific ril library to work (may be possible to build, has been done for Huawei modems).
4. No idea if this works for non-Sierra modems, obviously has to be adapted for other manufacturers. If you build the .ko for other devices, feel free to post it and I will add it to this post, it will help other people.
5. Probably tons of other issues that are lower level stuff.
Feel free to ask questions or give suggestions, we are in need of all the help with the Android part of this as we can get! You can also join us on #tegratab, I am Winnah9000 and ejhart is on there as well.
Updates:
Tried to use the parts from the Folio Update.zip, but they didn't fix anything.
You guys never cease to amaze me. Excellent work and great news for us to wake up to. As far as working, do I need to purchase an air card from Verizon(my phone carrier) or can I get one of the pay-as-you-go 3G air cards from Walmart to work with this? Also, I see you're using CM7, but what other roms does this work on? I'm using the GAdam alpha5 rom, do I need to switch back to TNT OEM rom to test this out? Thanks again for your feedback and your work.

Glad someone else was excited about this
I wouldn't purchase the air card as of yet since we aren't fully sure this will ever work. However, you do present an interesting idea. If we could use the pay-as-you-go cards and find a way around the data throttling like they did on the G2 this would be an extremely cheap way for a 3G Tegra 2 tablet.
To your ROM question. I'm using CM7 because the other ROMs (TnT Lite, VEGAn-Tab, etc.) lack the necessary telephony and communication apks that we would need for calling the data. Also, not sure which ROMs the pershoot kernel doesn't work on (I think it works on TnT Lite, CM7, and VEGAn when compiled correctly). You are welcome to test it on those when we get further along

Yeah, its the AirCard 250U sold by Sprint. Its 3G/4G, but the driver Sierra developed only does 3G cause they're lazy asses.
Here's the driver source and pppd dialing scripts: http://sierrawireless.custhelp.com/...-on-a-linux-operating-system-(-ac-850/860,-ac

Hi
as the Advent Vega has similar hardware (same oem part number i think?) then this might be of some help. Look at post 12 onwards. I have succesfully got this working with a Huawei E169 usb dongle.
http://android.modaco.com/content/advent-vega-vega-modaco-com/329229/mobile-broadband-dongles/
You have this working on the Viewsonic G tablet? Because I have tried to load the rom through Clockwork and the screen goes black. I need to know the secret.
OK, I discovered the ROM is loaded through ADB after extracting the files. Get a permission issue towards the end of the installation. Did you have that same issue? If so how did you overcome it?

I can't speak for all the devs / modders, but for me it's very simple. I don't have a 3G modem to even test with. My suggestion, in all seriousness, is to contact Viewsonic and ask them to add support into their firmware. And maybe ask for USB mouse support as well if you call them, I've already put in a ticket for that myself. The more people who call, the more likely that they might add it.
I have a aircard that the day job supplies, but the darn thing won't even work in MacOS or Linux, let along Android. I'm actually considering a MiFi device as it seems to be a fairly easy way to get around these issues.

I've reviewed this with ejhart but we didn't see much that they did which we didn't. The main issue is that most of the people who have it working are using Huawei brand 3G dongles which aren't used by carriers here, so they have different software pieces to make it work.

Roebeet has been in the IRC while we worked on it but he didn't have anything to contribute. The main issue is that none of them have a 3G dongle to work on it with, which also means its not a big deal for them to get it working (don't get me wrong, they still would like it to work, but they have more important things to work on).
Here are the sources for ril:

Thank you for this
However, we still have an issue. The RIL is pretty much coded for GSM only, there are some CDMA bits, but they look incomplete. I personally don't know enough programming to get it to work and ejhart already has other projects, so if someone wants to take it on, go for it!
That being said, this should probably work for GSM companies like T-Mobile, AT&T, etc. Feel free to try it if you know what you're doing
O please work.
I have been trying to get a 3G usb working since i got this thing. Im not computer programing savy enough to figure any of this out. I mean i know what your talking about, i understand it all, just cant program, so I hope you guys can work this out, would be in debt to you guys forever.
I will be calling viewsonic everyday as a differnet person say I want 3G mondem support and hopefully they will just build it in for us all.
Thanks again for all your work guys.

It almost seems to me that is why they gave it a standard USB port, as well as a mini port. It could be for stick drives, but then why was there a spot for a micro SD? Perhaps, the TNT people at VS were in such a rush to get the product to market, that they simply skipped this feature?

Because Micro SD cards are limited to 32GB, while USB thumb drives are at 256GB or you can use an external hard drive with power for 2 or 3 TB. They didn't put in the 3G support because they could've just sold the zPad (or w/e its called) with a 3G module slot. They sold this because its cheap and they didn't have to write extra drivers for 3G modem support.
EDIT: Also, the reference board for Tegra 2 has the USB port, so they probably threw it in for kicks.
this a workable solution:

Hi Folks
I have an Asus Transformer arriving in the next few days and in anticipation I bought a Telstra Ultimate Mobile USB modem.
Now I am hoping like hell I can use in on the tablet when it arrives .... can it be done ?
Thanks for reading and Mods can move this to somewhere else if I posted in the wrong area

Android has no support for USB network devices.
That said some rom builders for some devices have got some USB 3g dongles working on devices that have USB host mode ports (The TF doesn't have a USB host port without the keyboard dock)
Overall I'd say there is vanishingly small likelihood it would work out of the box and it's unlikely it will ever work.
Honeycomb 3.1 is supposed to include support for a much wider range of devices and I've seen reports that USB modems may be among these devices.
I'm planning to try my old Huawei E220 modem (if any device is supported it's going to be the E220) as soon as I get the update applied and see how I get on.

Sadly I've tried both a Huawei E220 and E160G without any success.
I haven't tried checking logcat etc when I plug in the device but at the moment the transformer doesn't recognise them as modems (or seem to show the micro-sd card reader on the E160G either but that may be down to a dodgy micro-sd card)
I can't say I'm exactly surprised as USB modem support wouldn't exactly help Asus to sell the 3G version of the Transformer (when it's finally released), but maybe the extra device support in 3.1 will make it easier for the dev community to add this functionality.
EEE use with Telstra Ultimate USB modem
Thanks for this thread.
Unfortunately, I have been caught on this too and have been searching for some answers. This site was the closest I found to something that applies.
I have tried it on the docking station host port and it does not even see it.
I tried fooling it by putting a copy of the installation software on a thumb-drive using another port, it saw the folder but would not execute any of the auto run files.
Looks to me like either Telstra or Android need a firmware version put into the hardware before we get any joy. It's too bad because it is a great tablet and the docking station is great.

Hello
I know this has been asked before, but no conclusion was presented.
I have an Huawei E173 3G usb modem i primarily use for my car stereo(Parrot Asteroid, this runs Android 1.5/1.6 this has support for a lot of usb dongles)
I want to to use this with my Wifi Xoom via an usb OTG cable.
As of now i doesn't work.
This because the lack of drivers and APN settings on the Xoom.
I have read the thread over at the XDA acer iconica tab forum about this, and they got it to work. ( http://forum.xda-developers.com/showthread.php?p=14603952 )
The android drivers for a lot of usb dongles exist, but how to get them to work on the xoom?
Tiamat kernel has the needed modules (usb_wwan.ko), so, you need just the script to set up connection. You can try with this one, maybe you need to change something...

Hi all,
I have searched high and low for an answer to this but cannot find a definitive answer so thought I would post it here.
does the xoom have or can we get access to the tegra serial debugging port or a serial console?
do we have any technical schematics for the xoom mainboard?
does the xoom have nvflash mode? if so is it open or is an SBK required?
I am really interested in getting serial console output of u-boot and early kernel boot stage. I have already tried to enable debug_ll and earlyprintk etc etc then output using a usb to serial cable but this only becomes available when usb device drivers are loaded which is reasonably late in the kernel init process.
currently the kernel config suggests the fiq debugger is run on uart-b I wonder if this uart-b is accessible on the mainboard or through the micro-usb/headphone port by creating a cable or setting a gpio as on the nexus one or attrix respectively.
thanks for any and all responses.

Unfortunately, as I have neither Xoom schematics, nor even the Tegra 2 TRM (NVidia never got back to me on my application, either ) I'm utterly unable to help you with this.
Thanks anyway.
