Can this usb modem work with the N800 or N810
 

I just noticed this Evdo usb modem by verizon, and it looks pretty good. Would it work with the N800 or N810

Re: Can this usb modem work with the N800 or N810
 

No, the N8x0 does not have host-mode USB, plug the power drain would we way to much.
I have a similar USB modem for 3G what need a double usb cable for the extra power input when been used on a normal Desktop\Laptop USB port.

Re: Can this usb modem work with the N800 or N810
 

Hm. The N810 has USB OTG.

USB OTG _can_ act as USB Host if you plug a non-OTG device into it.

So, I think the right questions are:

1) will the N810 act as a USB host if you plug one of these into it?
2) does maemo have the right drivers for powering one of those?

Re: Can this usb modem work with the N800 or N810
 

Exactly, the 810 has USB host (which I think is important?) and made me think it could work. I hope one of the forum experts might notice this post and reply. If this works, I would do it in a hearbeat.

Re: Can this usb modem work with the N800 or N810
 

In any case you would have to supply additional external power.

Re: Can this usb modem work with the N800 or N810
 

It does not have USB Host. It has USB OnTheGo, which _can_ act as USB Host. But that depends on whether or not the N810 is set up to fall into that mode when dealing with standard (non-OnTheGo) client devices. We don't know how the N810 behaves in that situation.


And, as I posted in another thread where you're asking about this, the device you're talking about has 2 strikes against it: doesn't claim linux support, and it's from Verizon. Sprint has one that does claim linux support (but no idea if that will work with maemo).

Re: Can this usb modem work with the N800 or N810
 

I have the Franklin CDU680 EVDO USB modem. It does include Ubuntu drivers and it configures as a PPP Dial-Up device. It's power needs are in the 100mA - 200mA range. Which are below 'normal' USB device power needs.

I have found places where people like this device for Linux systems because it supports the standard & extended AT command set and appears as a dial-up modem to the host system. It is the main reason I am now using Millenicom as my ISP over Sprint's EVDO network...the device is included in the deal and it's just $49.99 w/o beyond a month-to-month deal. I need the mobility and wanted the N800 as my device...because the brag sheet claimed a USB 2.0 port...I guess that was an exaggeration?

What I read in this thread is there is the USB port on the N8x0 devices does not supply any power? A small yet important disappointment.

Re: Can this usb modem work with the N800 or N810
 

Some clarification regarding the USB stuff here.
1) Both the N800 and N810 support USB On-The-Go. This means that they can act as client devices (default), or Host devices. To switch between client or host you can either use a special adapter (available for N800 here: http://www.electronicproductonline.c...oducts_id=1781,
still searching for the N810 version) or do it manually as described in the Wiki (works for both N800 and N810).
2) Both devices supply somewhere between 100-200ma of power (I forget the exact number now); if your device requires more than that then you need to use an external power supply/powered USB hub.
3) You need OS 2008 in order to use this functionality on either device.

I haven't heard of anyone using a USB modem yet, so additional kernel modules and drivers are probably required; I don't have a lot of porting/software devel experience though so don't know for sure, but I wanted to clarify the basic USB facts for all.

Thanks,

The ports on both the N800 and N810 are USB 2.0; that's not an exaggeration.

If your modem uses the AT command set and looks like a modem, you can probably use the usb-serial driver. So you should be able to get it started, use minicom to dial it, whatever. Once you get that working, ppp is presumably needed for the actual dial-up connection, but that's already used for BT DUN cell phone connections (I think). It looks (from here, where I've not yet used a data connection over my cell phone, and don't have my host-mode adapter yet) like all that's needed is some scripting to glue it all up. I remember doing that around 1999 or so to get Linux talking to a dial-up ISP over a regular (RS232) modem.

Re: Can this usb modem work with the N800 or N810
 

For now, I have the same modem and I use a cradlepoint 350 router.

http://www.evdoforums.com/viewforum.php?f=26

(their beta version available from 3gstore/evdoinfo supports the UM150, but they should have a new release soon)

1. It is properly recognized with the cdc_acm.ko kernel module.
2. The microSD works just like a thumbdrive or similar and will mount FAT/FAT32 media.
3. Either way it requires a powered hub and something (like an adapter with pins 4 and 5 shorted) to go into host mode.
4. lsusb, or pppd will eventually crash the USB subsystem due to a phantom endpoint causing a null pointer dereference. Reboot required for USB to recover. This does not appear to be the cdc_acm driver but the /sys/usb stuff (which is used instead of /proc/bus/usb so my Ubuntu Laptop doesn't easily duplicate the condition).
5. That said, I do get the IP address and DNS values, so as soon as I can figure out the more general USB problem, I won't need the router. Only when the data is blasted over the bus does the hiccup happen.

Re: Can this usb modem work with the N800 or N810
 

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.

Re: Can this usb modem work with the N800 or N810
 

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.

tz:

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... :D

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.

Re: Can this usb modem work with the N800 or N810
 

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.

Re: Can this usb modem work with the N800 or N810
 

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.

Re: Can this usb modem work with the N800 or N810
 

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?

Re: Can this usb modem work with the N800 or N810
 

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!

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.
