As fas as I can see here, the /dev/em8300-0 and /dev/em8300-1 are
exactly the same! (See 121, 0)

Devices on linux are specified by numbers: major and minor. The H+ is
device major 121, minor 0. The audio is 121,2 etc...

By creating another device with the same major and minor numbers you do
absolutely nothing. (you could also name the card
/dev/That_greeny_thing_inside_my_computer -- it wouldn't do any
difference)

eg> 2 - Modules initialisation:
eg> 
eg> # ./ldm
eg> and
eg> # ./em8300setup
eg> Microcode uploaded to /dev/em8300-0
eg> Current settings are:
eg> Video   Aspect  Audio   Spu
eg> PAL     4:3     ANALOG  ON
eg> Microcode uploaded to /dev/em8300-1
eg> Current settings are:
eg> Video   Aspect  Audio   Spu
eg> PAL     4:3     ANALOG  ON

Sure. You just upload the microcode to the same card twice.

eg> May be this is just a device setup problem, or inode creation  

Exactly... Search what happens on the major/minor numbers with multiple
DXR3/H+ cards...

eg> Thank for your help.

have fun!
