Hey,I am a new user and I think I am dealing with a complicate matter, and I would probably need help.I would like to use a firewire Audio device (RME Fireface 400) with Ubuntu 20.10. My computer doesn't have any native firewire output, so I try to connect it through thunderbolt (from thunderbolt-3 (UDB-c) to thunderbolt-2 and then to Firewire with adapters).I try to compile my kernel adding the ieee1394 drivers and all other possible things that may help (adding the CONFIG_SND_FIREFACE). But still when I type ~$ lsmod | grep fireface I dont get nothing. Instead, when I type ~$ lsmod | grep firewire I get firewire_sbp2 24576 0firewire_core 69632 1 firewire_sbp2crc_itu_t 16384 1 firewire_core and When I run lsusb, I apparently see only one dongle (or maybe the second adapter is transparent):
Bus 001 Device 005: ID 05ac:1657 Apple, Inc. Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter I know that I may use FFADO, but actually the things seems to be more complicated: the problem seems actually the connection that does not work properly (with the use of two adapters). I checked /etc/modprobe.d/blacklist.conf and there is no trace of firewire modules, and in /etc/modprobe.d/blacklist-firewire.conf everything is disabled: # Select the legacy firewire stack over the new CONFIG_FIREWIRE one. #blacklist ohci1394 #blacklist sbp2 #blacklist dv1394 #blacklist raw1394 #blacklist video1394 #blacklist firewire-ohci #blacklist firewire-sbp2 Now, here the output of the following commands (when RME is connected): lsusb, lspci rdw@rdw-linux:/etc/modprobe.d$ lsusbBus 002 Device 002: ID 0781:5583 SanDisk Corp.
