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

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.

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?

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.

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).

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.

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.

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.
