It's not just related, it goes to the core of the issue. :) Joerg assured us that we can do this. When the 47k resistor is present, EN_USBHOST will be disabled so power will be coming in from the outside on usb +5 to charge the battery and power the usb client, and neo's usb will be in host mode. -- Brad ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

A related question: I presume that it is the electrical signal EN_USBHOST which flips the switch which causes the USB port to source current in host mode, as opposed to sinking current in device mode. This is of course what is expected of a USB host, but it also prevents us from charging the Freerunner when the USB port is in host mode, if an appropriate power source is available.

not to sound like too much of a nut... I love my portable tech gear...
but there is a battery-operated hub that might be interesting to toss
in the mix ("CP-H420MP"). I'm ordering one now to try it together with
everything.

ppp stuff is either in the rootfs or it is just an opkg install away.
I had to add option and usbserial from the modules tarball.

Re: 3G USB Dongle (was Re: Neo as cellular modem?)
That must be a really power hungry one... I plan on using my 3G / HSDPA Nokia E51 with the FreeRunner, probably over Bluetooth, but if that is too slow, then I'll give USB a shot. It doesn't charge over USB, so it shouldn't need too much power.

I only had to add the modules "option" and "usbserial" to work with the 3g adapter. it's a cdma/evdo adapter from verizon. http://chockerblockablog.blogspot.com/2008/03/neo1973-no-wifi3gbattery-life-no.html it's not too hard to make the neo act as a bluetooth access point to multiple devices and also bt dun server for one more device. I haven't set this up on the neo yet but I did do that with a gumstix. i think it may still be up in the air how to run a usb device and keep the freerunner charging externally. this 3g adapter i'm using draws a lot of power, so it almost certainly won't work when only powered from a freerunner's battery. -- Brad ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
3G USB Dongle (was Re: Neo as cellular modem?)
That's a great idea Matt! Might be a drain on the battery moving packets around though. Speaking of which, would anyone know if it would be possible to use a 3G USB dongle on one of these? I can't see why not. I have a friend here in Australia who users a Three (Hutchinson) network USB dongle plugged into his Ubuntu box. He tells me it uses PPP to dialin and it's as easy as pie. Can anyone shed some light on this? Cheers, Nick Matt Mets wrote: It should be no problem. You just have to set up your routing tables correctly so that the desktop knows to route its traffic to the device, and the device knows to forward traffic to the cellular connection. It would be really handy to have an application to configure all of this automagically. It might also be cool to have the Freerunner act as a wireless router! Instant (slow) internet anywhere... Hi, I'm was sitting in my workshop with the cable modem out and the local wireless not working correctly and so no internet access today, wondering if we can expect to use the FreeRunner/Openmoko as a cellular modem at any point.
