The USB-bus does not recognize the Logitech C120 cam. However another USB-device such as a USB-stick is fully recognized. HardInfo says: OHCI Host Controller - Unknown USB 2.00 Device (class 239) dmesg -l |grep uvc says: uvcvideo: Found UVC 1.00 device <unnamed> (046d:080f) uvcvideo: No valid video chain found Kernel: Linux 2.6.30.5 Who can help? |

Your Logitech C200 requires a very recent version of the uvcvideo driver, available with the latest kernel 2.6.33. The most recent Quirky or Wary test release should have this driver. |

Thanks, in Quicky I do not see the 'no video chain' error message. Unfortunately there is another one: I cannot connect via the wireless card. After selecting the driver, the card does not become active. The same for Wary |

Details? Wifi card - manufacturer, model, revision?
Which driver, specifically? |

Quicky does not do anything with the airo_cs driver for the Cisco Aironet 350 pcmcia. In puppy 4.2.1 everything was fine. No problems with the Network Whizzard. Thanks, HJ. |

'No valid video chain found' And: 'OHCI Host Controller - Unknown USB 2.00 Device (class 239).' I think something goes wrong at the USB. |

OK, it seems that hacked device detection is not good enough, your device needs updated driver code. I have just deleted the test driver for 4.3.x in the earlier post.
There's nothing exotic about the old airo_cs driver, you should diagnose the problem. First check that the PCMCIA system recognises your device with these 2 commands -
If your wifi device is listed, run this command
and look for information about how the airo_cs driver loaded. If you cannot see your device listed, refer to this information about how to reset the Cardbus interface - http://www.murga-linux.com/puppy/viewtopic.php?p=31707#31707 |

Are we now starting to see situations where users assume that Quirky is a general-purpose Puppy when it really isn't? |

Thanks for your help so far. Most important now is the get the cam working, if it can. I leave it now for a while. |

As the Logitech C120 cam provides the Hi-Speed USB 2.0 certified.The standard drivers are provided by the Operating System and will only provide minimal camera support whith the USB. Your device needs update drivers to have compatibility with the puppy Linux.and For updates on compatibility issues and driver support, please continue to check the Support C120. _________________ Where there is will there is way. |

Wha?
Which drivers? As we have been discussing, the only driver for the Logitech C120 compatible under Linux is the uvcvideo kernel module, and as Henk-Jan has indicated, albeit unclearly, this driver appears to work under the 2.6.33 kernel -
Where? Who? What are you talking about? The Logitech website? That's no help, they only provide Windows drivers. |
