I've downloaded the last git easycap-somagic-linux source version.
After, i've compiled and installed the easycap kernel diver without any problem.
I've extracted and installed firmware from 
SmiUsbGrabber3E/xp/SmiUsbGrabber3E.sys without any problem, whit 
somagic-extract-firmware tool.
When i attach the usb device this is the kernel messages:

There is no device /dev/videox created.
Now i've changed easycap-somagic-linux/kernel/somagic.h whit this:
//#define SOMAGIC_USB_PRODUCT_ID 0x003c
#define SOMAGIC_USB_PRODUCT_ID 0x003e
After loaded the kernel module now i see:

Now When i use vlc for capturing the program wait indefinitelly 
vlc -vvv "v4l2:///dev/video0"
whith this cutted output:

And in this point wait..............
Using userspace somagic_capture utility the situation is identically.
the cose is looped in this while loop, witouoit any output:
while (pending_requests > 0){
    libusb_handle_events(NULL);
}
Can i do something?
Thanks in advance.
Best regards.
Vito.

Does the user space capture (somagic-capture) work when you have active video 
connected to composite plug "2" on the device?
