Yes, you're correct. I'm using then 1.1.1. Sorry by the mistake.

First of all, I downloaded the CVS version, but I reject it cause the kernel version needed was 2.6.13.rc5 (or someone similar). Instead downloading and recompiling that realease candidate kernel, I chose to get older version of dvb-kernel, the 1.1.1 (sorry again).

Ok, I executed the lsusb and the output was:

Bus 004 Device 006: ID 04b4:8613 Cypress Semiconductor Corp. CY7C68013 EZ-USB FX2 USB 2.0 Development Kit
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

This output is ok. Let me explain. The box is not a REAL box. I'm developing in this device and I have the cards over my table. The DiBcom EVA3000MC have a MPEG-2 output, and there is another card to convert the MPEG-2 output to an USB 2.0 output. This card is also given by DiBcom, but I see a chip with that description (CY7C68013...)

Then, I have now the ID (04b4:8613). What can I do with it? Is it possible that this ID-missing caused my problem?

Yes. That firmware is at /usr/lib/hotplug/firmware.

Uff...   :D   Thanks a lot.
