OLA and Enttec Open DMX USB

[RitterSport]

Hello,

I have an Enttec Open DMX USB Device and I installed OLA.
But when I do ola_dev_info
there's no opendmx Device,

dmesg shows:
[11182.988101] usb 2-3: new full speed USB device using ohci_hcd and
address 4

[11183.230277] usb 2-3: FTDI USB Serial Device converter now attached

so i changed the file: ola-opendmx.conf to ttyUSB1
now the OpenDmx USB Device is shown. and I can connect de Device, Port
und Universe.

ola_dev_info
Device 5: OpenDmx USB Device
port 0, OUT Open Dmx at /dev/ttyUSB1, patched to universe 0

But when I change dmx values, nothing happens. The lamps are still
off.

Can someone help me please?

Did you load the kernel module? See

you're right, i forgot the kernel module,

but when I try todo a make, i got an error:

It looks like the kernel interface has changed. If you search for
"implicit declaration of function ‘init_MUTEX’" you'll see other
people having the same problem.

http://code.google.com/p/open1211/issues/detail?id=5 is one example

Thank you. now it works fine.

for Kernel 2.6.37 the dmx_usb.c file needs a few changes:

DECLARE_MUTEX -> DEFINE_SEMAPHORE
init_MUTEX() -> sema_init
.ioctl -> .unlocked_ioctl
