Failed to claim device interface: Device or resource busy

[GoogleCodeExporter]

Hi,
I've a problem with this driver.
I installed latest version (1.1) on a ubuntu 13.04 64bit (kernel 
3.8.0-19-generic).
Compiled the kernel modules and loaded.
But when I execute a "somagic-capture --test-only", I get this message:
Failed to claim device interface: Device or resource busy

Dmesg says:

I have the same issue.
OS - ubuntu 13.04 64bit (kernel 3.8.0-19-generic).

The same errors in dmesg. I have compiled kernel modules, extracted firmware 
and renamed it to smi2021_3c.bin. Added such lines to /etc/modules:
saa7115
uvcvideo
smi2021_bootloader
smi2021

But after reboot I get such output in dmesg:

Did you find a solution guys? 
I am using ubuntu 13.04 and kernel 3.8.13.. and applied Jon patch ver 4... and 
still have issue but with a _3f device:
- same above errors writing to registries and device buzy on somagic-capture; 
- the /dev/video0 appears but not working with motion or avplay or other 
viewers. 
- I have 4 video inputs in the device and only one /dev/video0 is there.

Any help will be appreciate.

I have completely installed it on ubuntu 13.04 64bit (kernel 3.8.0-19-generic) 
and all works pretty well. Here is my guide:

1. Install the following packages:
sudo apt-get install git build-essential libusb-1.0-0-dev libgcrypt11-dev 
usbutils
For Debian install linux headers:
sudo apt-get install linux-headers-$(uname -r)

2. Clone project from git
git clone https://code.google.com/p/easycap-somagic-linux/

3. Compile utility for firmware extraction
cd easycap-somagic-linux/tools/somagic-extract-firmware
make && sudo make install

4. Extract firmware from file (SmiUsbGrabberXX.sys) that you may find after 
Windows driver installation.
sudo somagic-extract-firmware SmiUsbGrabberXX.sys

5. There will be firmware file called somagic_firmware.bin in /lib/firmware 
afer extract. You must rename it with version suffix (3c in my case)
sudo cp /lib/firmware/somagic_firmware.bin /lib/firmware/smi2021_3c.bin

6. Compile kernel driver
cd ../../kernel
make

7. There will be 2 files after compilation: smi2021.ko and 
smi2021_bootloader.ko. Copy them to the directory of current kernel
sudo cp smi2021.ko /lib/modules/$(uname -r)/kernel/drivers/media/usb/smi2021
sudo cp smi2021_bootloader.ko /lib/modules/$(uname 
-r)/kernel/drivers/media/usb/smi2021

8. Add the following lines to /etc/modules
videodev
saa7115
uvcvideo
snd-usb-audio # If you see snd_pcm_* errors
smi2021_bootloader # Initializes device
smi2021

9. Update drivers tree
depmod -a

Good luck ;)

Hi, I tried all steps in #5 from paul, without problems.
But nothing, when I launch capturing, I get same results and same errors!

On latest ubuntu update, kernel 3.8.0-30-generic 64bit.

Thank's for your help....

Sob sob sob sob....no luck :-(

The developer has written new post about kernel module building not far ago. 
You can read it here:
