Hi Clemens,

I'd like to request the following patch to be applied on the firewire-kernel-streaming branch (current commit head 526795d69f5be6d058bdf89a65a303a1ee136aba). It involves handling Weiss DICE devices which use a dedicated category ID (other than TCAT's default Cat ID (0x04), which is not necessarily binding). Citing (one of many) TC's user guide:

[...] The manufacturer is free to use the lower 5 bytes of the WWUID in any way. The DICE firmware, by default, uses the chip ID as follows:

Upper 32 bits of WWUID +------------------------+--------+ | 24 bit OUI – 0x000166 | Cat | +------------------------+--------+ Category 8 bits: TCAT uses 0x04 for this field.

Lower 32 bits of WWUID +----------------------------+----------------+ | 10 bit product identifier | 22 bit serial# | +----------------------------+----------------+ [...]

Presumably, few of the other vendors have changed TCATs default Cat. ID. We have decided to change it to 0x00 since the beginning of our DICE product-line, alas this should be considered in snd-dice's dice_interface_check. Thanks in advance.
