P.S. the content of configuration ROM can be dumped by config-rom-pretty-printer in linux-firewire-utils. The node of your device has: guid: 0x22e0001800000 vendor_id: 0x00022e model_id: 0x800006 It includes one unit: specifier id: 0x00022e version: 0x800006 model_id: 0x00022e It is odd that the node and unit has the different values for their model_id fields. I think Tascam programmer applied the wrong configuration to them when developing dice firmware Note that ALSA dice driver is bound to the unit, thus both vendor_id and model_id should be 0x00022e. $ config-rom-pretty-printer < audio_and_music/dice/tascam-iffw2.img ROM header and bus information block ----------------------------------------------------------------- 1024 04042ec6 bus_info_length 4, crc_length 4, crc 11974 1028 31333934 bus_name "1394" 1032 e0ff8112 irmc 1, cmc 1, isc 1, bmc 0, pmc 0, cyc_clk_acc 255, max_rec 8 (512), max_rom 1, gen 1, spd 2 (S400) 1036 00022e00 company_id 00022e | 1040 01800000 device_id 0025165824 | EUI-64 0613527513464832 root directory ----------------------------------------------------------------- 1044 0006f261 directory_length 6, crc 62049 1048 0300022e vendor 1052 8100000a --> descriptor leaf at 1092 1056 17800006 model 1060 8100000d --> descriptor leaf at 1112 1064 0c0087c0 node capabilities: per IEEE 1394 1068 d1000001 --> unit directory at 1072 unit directory at 1072 ----------------------------------------------------------------- 1072 000411c4 directory_length 4, crc 4548 1076 1200022e specifier id 1080 13800006 version 1084 1700022e model 1088 8100000d --> descriptor leaf at 1140 descriptor leaf at 1092 ----------------------------------------------------------------- 1092 0004a79e leaf_length 4, crc 42910 1096 00000000 textual descriptor 1100 00000000 minimal ASCII 1104 54415343 "TASC" 1108 414d0000 "AM" descriptor leaf at 1112 ----------------------------------------------------------------- 1112 00066bda leaf_length 6, crc 27610 1116 00000000 textual descriptor 1120 00000000 minimal ASCII 1124 49462d46 "IF-F" 1128 572f444d "W/DM" 1132 206d6b49 " mkI" 1136 49000000 "I" descriptor leaf at 1140 ----------------------------------------------------------------- 1140 00066bda leaf_length 6, crc 27610 1144 00000000 textual descriptor 1148 00000000 minimal ASCII 1152 49462d46 "IF-F" 1156 572f444d "W/DM" 1160 206d6b49 " mkI" 1164 49000000 "I" Regards Takashi Sakamoto |
