Feature requests & roadmap / Multiple USB security camera sensors on one USB bus

« on: February 20, 2010, 08:29:34 pm »

If we were to set security-specific USB cameras to only take snapshots once every five seconds, regardless of which orbiter was accessing them, we could then create a software alternator to switch between cameras on the same bus so that only one camera would be running at a time.  This would allow for multiple USB cameras to be installed on LMCE on the same bus.  The hope is that this would allow people to set up a fully functional, state-of-the-art security system using nothing more than one computer, a network of usb hubs, and USB webcams set up as security cameras.

Is this a possibility?

Users / Multiple USB security camera sensors...?

I need help setting up multiple USB camera sensors.  I read somewhere that it is bad to connect multiple USB cameras to the same USB bus, but that it might be possible to modify the driver to provide enough bandwidth to run multiple USB cameras on the same USB bus.  How is this done?  I need to connect two or three of them to the same USB hub if possible, which would clearly be a USB bandwidth overload unless the driver is modified as suggested above.

Installation issues / Re: Recovering from a failed install

This sounds like a driver issue with the device you are using for eth0.  Try this:

$:lspci -v

Check to see where your ethernet controller is.  It should have the pertinent device information on the first line.  mine reads like this:

02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 03)

Notice the device numbers, ie "RTL8111/8168B."  The last two lines under the Ethernet controller device should indicate which drivers are in use.  For me:

Kernel driver in use: r8169
Kernel modules: r8169

This driver does not work for this device in earlier ubuntu distributions, as the device is 8168B and not 8169.  If you have a similar problem, google your device and driver and see what you come up with in the regular ubuntu or kubuntu forums.  You might be able to replace the driver from the command line and hopefully that will get your Internet connection up and running, though I don't know for sure if LMCE uses the same Ethernet drivers as ubuntu does.

(this computer is running on ubuntu 9.10, due to my failure to install LMCE on it)
