Ubuntu – Adding a new USB PCI card

installationpciusb

I'm completely new to Ubuntu. I've installed Xubuntu 11 on an old machine quite successfully and plugged a wireless dongle into one of its on board USB1.1 ports, giving me wireless internet without too much trouble.

I've now bought a USB 2.0 PCI card and installed it, hoping that it would be picked up automatically on boot and I could connect via USB2.0. Unfortunately I think it's not being recognised.

I have the following outputs from lsusb and lspci:

lsusb

Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 002: ID 050d:705a Belkin Components F5D7050 Wireless G Adapter v3000 [Ralink RT2573]
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

sudo lspci -v

    Flags: medium devsel, IRQ 9
    Memory at ec000000 (32-bit, non-prefetchable) [size=256]

Can anyone please suggest how I can overcome this problem? Automatic detect/configure tools would be best, but I'm prepared to edit config files if necessary. A Google on 'linux + install new hardware' wasn't too illuminating, I apologize if this has been asked before.

Update

Doing a dmesg | grep ehci, gives a 'startup error -19' entry and 'USB bus 1 deregistered'. Googling for the 1st error gives lots of hits all related to problems with USB 2.0 and the kernel in 10.10. maybe it's still a kernel problem with 11.04

Best Answer

Your latest update looks interesting "Doing a dmesg | grep ehci, gives a 'startup error -19' entry and 'USB bus 1 deregistered'. " - I had a similar issue when adding PCI cards.

I found a couple of issues - I had ran out of IRQs - i.e. I had added too many cards - I pulled all cards that could use multiple IRQs e.g. firewire and these sort of error messages in dmesg stopped.

I also had to turn off USB Legacy Support in the BIOS.

Hope this helps.

This contains instructions for compiling from source, and is for a different model. this could cause problems with future updates breaking the compatibility of these instructions

Unplug the card from your PC (if you have already plugged it )
To run V4L (Video4Linux) Driver in system, you need following packages, make sure you add them through your Synaptic Package Manager.

mercurial

gcc

build-essential

linux-source

AND

type following to download and install your linux headers which is compatible with your kernel

sudo apt-get install linux-headers-`uname -r`

You must get a copy of the V4L (Video4Linux) Driver to do so tap the following code in a terminal

$ mkdir tvdrviver

$ cd tvdriver

$ hg clone http://mcentral.de/hg/~mrec/v4l-dvb-kernel

above commands will download a copy of V4l Driver into your tvdriver folder.

Now we have to build the V4L driver and install it into the kernel. to so take following lines in your terminal window.

$ cd v4l-dvb-kernel

$ make

$ sudo make install`

if every thing goes good it will install the driver in few mins without any errors.

At this point your must REBOOT your box (b4 you do so remeber to book mark this page )

You have installed your driver, now it's time to load the Driver. Before we do that I have to tell you this is where my problem was, coz the Driver couldn't detect my device automatically

so until it can't detect the device it will not give you /dev/video0

so what we have to do is we have to do detecting part manually. how we do it..? this is how.

The em28xx accepts the parameter 'card=' when it's loading, is where you have to mention your device number from the driver device list. so my device is listed on 37th location in the list So I'll load my device in to the driver as follows

Reference Check out: http://ubuntuforums.org/showthread.php?t=646528 . The instructions are for a different model (UTV 330)

The answer is: it's not actually your problem.

Some logitech cameras have usb bandwidth allocation bug. Lets see if that's the case.

cat /sys/kernel/debug/usb/devices | grep "B: "

will give you current bandwidth allocation of all usb hubs, output will be something like this:

B:  Alloc=  0/900 us ( 0%), #Int=  0, #Iso=  0
B:  Alloc=  0/900 us ( 0%), #Int=  0, #Iso=  0
B:  Alloc=  0/900 us ( 0%), #Int=  0, #Iso=  0
B:  Alloc= 35/900 us ( 4%), #Int=  3, #Iso=  0
B:  Alloc=  0/900 us ( 0%), #Int=  0, #Iso=  0
B:  Alloc=  0/800 us ( 0%), #Int=  0, #Iso=  0
B:  Alloc=  0/800 us ( 0%), #Int=  0, #Iso=  0

As you can see, I currently have 35 mbps allocated of my usb3 hub. The problem with some logitech cameras, though, is that they will always allocate as much as they can get (480 mbps), disregarding of mode. And so it's down to simple arithmetic as 480 + 480 > 900 and second camera just "won't fit".

As long as your cameras are plugged in the same hardware usb hub, you will have that problem.

Also bear in mind, that webcamera usually allocates 128mbps in MJPEG and 424mbps in uncompressed mode for 640x480.
