Actually this is sounding promising, thanks for all the detailed info about the setup. For me it is a lucky side effect that the Franklin CDU680 does setup and function as if it was an AT command set modem. It's one, er, main, reason it can function on a Linux system. The device works as a USB drive and comes with software for Ubuntu installed on the device. So it does work in Linux. The Ubuntu drivers/setup might not work in OS2008 but it sounds like it would be just a simple manual setup for the modem and then it depends on the actual power supplied to the port.

I was hoping to eliminate the need for a Cradlepoint router, either the CTR350 or the PHS300[which has a Li-ION battery built in so that is SLICK]. I would rather just use the USB device connected to the tablet as it must use less power then Wifi connecting to the router...I think? Of course that brings to might the router does also act as a firewall...hmmmm...more decisions.

But if the only roadblock is the USB port I could get an N8x0 and one of the Cradlepoints.

Both Cradlepoints have their pro's & con's. The CTR350 needs power but you can use an external power pack easily enough and there are plenty of options. But that is a bulky solution. And if I am using it to travel then the routers LAN/WAN port is not really of much use since it sort of defeats the idea or portable if the tablet needs to be wired in...

The PHS300 has that built in LiOH battery that seems to get a good 2-3hrs of life while browsing. And since it can be connected to a wall socket (to charge or preserve battery life for when there is not a wall socket around) when available then it still retains the idea of portability.

Still either option is a kludge at best, but a kludge is "old timers" for "it works doesn't it???!!...so shaddup!!" But it's an expensive kludge at $130-$170ish (plus another $60-$100 for an external LiOH battery pack if you go the CTR350 route).

But maybe my best chance is to simply try the modem out and see what develops. At least it would be something fun to try and not a dead end like my nx73v has sadly become.

You know I think maybe I'll email the folks at both Franklin and my EVDO ISP, Millenicom and see if they have anyone there who has tried this out on a Nokia N8x0 series tablet.

First, in your Ubuntu setup (sounds very similar to mine) when you insert the modem, what do you see in the output from dmesg? and lsmod? That should indicate which modules you will need for the n810. cdc_acm.ko in my case, but usb_serial and/or airprime might be needed and may work better. You still might need a powered hub.

If you can get it recognized, then the next step is to create a default connection setting (see the articles on using USB to your computer instead of mounting the flash drives from the tablet). Then point pppd at it (requiring a script I can't describe in a few lines). If that comes up, and the usb subsystem doesn't crash, you won't need the cradlepoint.

My OTG adapter just arrived yesterday. So, I am almost ready to give this a shot and see where it goes. I have an extra HDD that I am going to install Ubuntu on so I can test against that OS.

Having never run Linux before and it having been 15 years since my last experience with a Unix-like OS (Solaris on a SparcStation II & QNX running a 286 network...yeah, it was THAT long ago when 1MB of RAM was awesome...hahahaha...and here I am still playing with this crapola...

Anyway, since I basically dunno nuttin' 'bout Linux it will be slow going for me. Gives me something to waste heartbeats on other than TV.

BTW, so far it's not promising that the OTG adapter will help run the CDU680 EVDO modem as the power light does not come on when I connect the modem to the dongle. And I haven't been able to get a good meter reading on if any power is even being supplied to the port via the adapter.

OK...I just cut open a USB cable and attached it to the OTG adapter. I get ONE test of 5v power but then it poof's away until I remove the OTG adapter and reconnect it. Not sure what that means but there is voltage being supplied. I have no idea how much current is supplied yet.

But if the voltage can't be sustained then it won't work.

EDIT: Well, just for giggles I checked the voltage on a laptop. When I test it the system detects the test as a power surge and requires the USB subsystem be reset. So maybe that is what is happening on the tablet. The USB doesn't care for being poked and prod'd. ???

Anyway maybe all is not lost and if we can sleuth out the config it could still work. which would be very nice.

I found this thread through google and thought I'd resurrect it after a month to find out if there's been any progress made on using the CDU680 with the n810. I currently have a CDU680, and am thinking of buying the n810, ipod touch, or other similar device, and support for the 680 without the need for a EVDO router would be a big plus.

Really wish I could get my hands on a Sprint CDU680 to help test this out. Right now I've got a U727 that I'm working towards getting properly recognized, I've found the scripts to unmount the driver "cdrom" (useless in Linux and especially OS2008) with udev and I've got some excellent configs for ppp to connect to Sprint, just need to get my ttyUSB0 showing up on the N800. Anyone have a compiled version of the usbserial and/or airprime modules for Diablo?

Wow. This is a very interesting chat. I just bought a N810 and want to use it for my live streaming here: http://tinyurl.com/5vovfx .

Any help in setting this up would be very much appreciated. If a person with right qualifications was interested I could send the unit and whatever modem they wanted to try to them to help set up in exchange for some scottevest credits for clothing, etc. I don't see why this could not be done, but I personally don't have the ability.

Thanks!

Sincerely,

PS: I would need the N810 restored to normal if it didn't work and hope to loan machine out for no more than a week, if doable. If you get me the list of parts, etc. I can order them and ship directly to you.

Thanks for reading and considering. BTW, u can find me on twitter too @scottevest

PPS: Lastly, did you see this modem? Not sure if this has coverage where I live, Ketchum, Idaho.
