Re: N800 USB Host Mode Experiment
 
Wow ... I am pretty happy that OS2008 on the N800 works with USB Flash Drives. That makes it even more impressive. It even popped up a USB applet that allowed me to unmount the drive before pulling it out.

Hopefully someone makes a nice little applet (maybe a super-set of the functionality of the current USB applet that pops up) that allows you to switch modes without the hassle of opening an xterm ... or maybe I will look into investing in a USB OTG cable.

Good stuff.

Would someone please check the wiki to make sure that I have got it right?

Also has anyone tried Maemo Mapper with the maps on a usb thumbdrive? Save my flash memory for other stuff...

Thanks

Well, not really: if you don't consider resource limited devices, like our tablet, any old computer (by today standards) can easily decode mpeg. And if it's not that old it can even decode HD streams (though, at least over here, for dvb-t there are only experimental transmissions)

Is there *any* USB2 DVB-T card that also does hardware decoding?
I don't know any, but you could take a look at linuxtv.org

Until then we must use the same kludges used for the N800.

but you need to buy a thousand :(

/edit - or would this work?

with a regular to mini usb converter.

geminiii42:
The problem with either of those cables is that one would still need another adapter piece to connect to devices. However, if it works for data, the micro-to-mini adapter is the most ideal at this point. I've only seen them described in reference to charging, though.

Why do those Micro-A cables to full-size A-plug even exist in retail? Both ends are for host devices! They serve no purpose that a (soon to be commonplace) Micro-B cable does not fulfill.

Re: N800 USB Host Mode Experiment
 
this is an interesting article http://www.accesscomms.com.au/Reference/USB.htm

seems like there is a resistor that connects the ID pin to ground! someone more intelligent than me please research this and give a pin-out scheme for making this usb host cable :D

EDIT: http://www.maxim-ic.com/appnotes.cfm...e_number/1822/ seems like on the host side the ID (pin4) needs to be connected to ground (pin5)

Hi guys
Yesterday I got an usb wifi dongle working on my N800(OS2880), it's based on the RaLink rt73 chip and the driver has support for packet injection (muuhahahahaha).

My question is: how do I get around the manual loading of the rt73 kernel module? do I have to edit some configuration files or something like that?

modprobe the kernel module.

We can request for samples.

Tried that and it doesn't work, error msg is: cannot parse modules.dep
Do you know the path where is should copy the kernel module to?
