Hi,
I recently bought a philips mini projector model PicoPix of 1020 but not recognized by ubuntu 10.10.

this is the result of lsusb:

I have done the following:
1) I wrote in / etc / usb_modeswitch.conf

Code: Select all

# Configuration for the usb_modeswitch package, a mode switching tool for
# USB devices providing multiple states or modes
#
# This file is evaluated by the wrapper script "usb_modeswitch_dispatcher"
# in /usr/sbin
# To enable an option, set it to "1", "yes" or "true" (case doesn't matter)
# Everything else counts as "disable"


# Disable automatic mode switching globally (e.g. to access the original
# install storage)

DisableSwitching=0


# Enable logging (results in a extensive report file in /var/log, named
# "usb_modeswitch_<interface-name>"
# PicoPix 1020

EnableLogging=1


DefaultVendor = 0x1de1
DefaultProduct = 0x1101
TargetVendor= 0×1de1
TargetProduct= 0×1101


MessageContent = "555342430890d8f90000000000000cff020000000000000000000000000000"

2) After I created the file (again as root in a terminal) / etc/udev/rules.d/10-switch-picopix.rules AND I WROTE:

Code: Select all

picopix 1020

SUBSYSTEM=="usb", SYSFS{idVendor}=="1de1", SYSFS{idProduct}=="1101", RUN+="/usr/sbin/usb_modeswitch –default-vendor 0×1de1 –default-product 0×1101 –messagecontent 555342430890d8f90000000000000cff020000000000000000000000000000"

3) When I run the command sudo usb_modeswitch-c / etc / usb_modeswitch.conf My projector projects a light PicoPix 1020 blurred the invisible wall (if you unplug the cable and then reconnect it returns to normal projecting a white image with the words PHILIPS, but not the video on my PC), moreover, always after running the command sudo usb_modeswitch-c / etc / usb_modeswitch.conf I get the following message:

you can solve the problem? suggestions? new ideas?
....thanks!

The following is not clear to me:

- What is supposed to happen after switching? What is the behaviour in Windows?

- Where did you get that switching command from? Did you sniff in Windows?

Two side notes:

1. Don't use "/etc/usb_modeswitch.conf" for device-specific parameters! See main doc page for details about the purpose of that file.

2. Run "lsusb" as root or with "sudo".

When I connect the projector with usb windows, automatic part of the program "Install.exe PicoPix viewer", and once installed run the program "viewer.exe" and everything works properly.
In Ubuntu / Linux, when I connect the projector to the USB device is recognized but when installing the program as "wine" then it does not run (PicoPix viewer obviously does not work). So the projector shows a white image with the word indefinitely philips.

Here is a link where I got the documentation:
http://www.mail-archive.com/linux-uvc-d ... 05720.html

How can I do? I do not know what to do ...

O.K., I found the information about the mode switching.

The problem is that it will not help you very much as long as there is no application for the device that runs in Linux.

You succeeded with the mode switching obviously. What happens if you start Wine after that ?
Is there any error message if you try to start the Windows application ? If so, there may be a Windows driver missing.

Unfortunately, I'm not familiar with Wine, so you have to ask elsewhere how to set it up.
