I'm trying now to initiate an isochronous listen with the sample application
'Win1394' on kmdf sample driver for 1394.

For Setting Up Isochronous Transfer :

1. I allocate bandwidth with 280 Bytes per frame and 200Mpbs for speed.

2. I allocate requested channel with ffffffff

3. I allocate Resources with :
speed : 200Mpbs,
flags for 'Listening, Strip Additional Quadlets and Packet Based',
channel : ffffffff,
max. Bytes per frame : 280,
number of buffers : 2,
max buffer size : 25800,
quadlets to strip : 1.

4. I attache buffers with :
Resouce : the handle that I got after allocating Resources
number of descriptors : 2
no flags.
Length : 25800
max. Bytes per frame : 280,
tag value, synch value, cycle offset, cycle count and second count : 0

5. Isoch Listen with
Resouce Handle : the handle that I got after allocating Resources

At least, when I click the OK button I get the error 1450
(Error_no_system_resources).

Did I miss something by set up or take wrong value for something?

Could someone help me?

Thanks in advance
regards
