Guys, sorry i don't have much knowledge about USB HOST MODE, but is it possible that we use N900 as a host-mode as well as charging it? I know that during this mode, BME is stopped. But who know we can still give a command to Battery management to draw power from the USB port to charge the battery. For sure we can create such cable that provide an external power port to power the N900 and attached device.

you have to remap the joypad event into the keyboard. I have compiled Xjoypad for ubuntu into Maemo. You can download it from 4shared.




http://www.4shared.com/file/sO2p4sJN...p_xjoypad.html

copy to your /usr/bin and put permission for that file.

Also the much requested hostmode while charging (N900 works as USB host but does not supply VBUS 5V - this will be done by a modified hub or a Y-cable: http://wiki.openmoko.org/wiki/Specia...aka_Y-Cable.29) is not yet supported.

Wait for a version of jrbme integrating management of VBUS (incl. "charging hostmode") as well as hostmode enabling and notifications to user, to come in a few weeks.

Your dmesg clearly shows it's recognized and enumerated as high speed device. To me it looks like it's drawing too much power or sth, and so resets and starts over again enumerating. Anyway there's even a video driver loaded for it.
Obviously it won't show up in file manager, what would you expect to see? A mpeg video file?

If it works and driver works.... I guess you then could access it similarly to internal cams which are /dev/video0 and /dev/video1

cheers

You can use it with mplayer. Try something like this.
Code:
mplayer  tv:// -tv driver=v4l2:device=/dev/video0
Change /dev/video0. To find all the cameras attached (and working), use:
Code:
ls /dev/video*
/dev/video0 is the back camera
/dev/video1 is the front camera
and /dev/video2 should be your USB camera.

I have a Logitech Webcam Pro 9000 Webcam, works on my Ubuntu, the N900 is detected but the commands you indicate only shows green screen.

I've noticed that you didn't type the code correctly... "v4l2" stands for "Video 4 Linux 2" input, so make sure you enter letter "l", not digit "1"
