Assuming I have a firewire card with a supported chipset, is there anything special I need to do in order for the kernel to recognize the card? Shouldn't kudzu "wake up" and configure the card when I boot up after installing it? This is a brand spanking new 4.4 system and a supported Agere chipset firewire card. I'm having trouble tickling devices connected to the card. In particular, I'm trying to mount a firewire external DVD device. Lspsi shows the following so I *thought* the kernel found the card: [ritz at localhost ~]$ /sbin/lspci 00:06.0 PCI bridge: Advanced Micro Devices [AMD] AMD-8111 PCI (rev 07) 00:07.0 ISA bridge: Advanced Micro Devices [AMD] AMD-8111 LPC (rev 05) 00:07.1 IDE interface: Advanced Micro Devices [AMD] AMD-8111 IDE (rev 03) 00:07.2 SMBus: Advanced Micro Devices [AMD] AMD-8111 SMBus 2.0 (rev 02) 00:07.3 Bridge: Advanced Micro Devices [AMD] AMD-8111 ACPI (rev 05) 00:0a.0 PCI bridge: Advanced Micro Devices [AMD] AMD-8131 PCI-X Bridge (rev 13) 00:0a.1 PIC: Advanced Micro Devices [AMD] AMD-8131 PCI-X IOAPIC (rev 01) 00:0b.0 PCI bridge: Advanced Micro Devices [AMD] AMD-8131 PCI-X Bridge (rev 13) 00:0b.1 PIC: Advanced Micro Devices [AMD] AMD-8131 PCI-X IOAPIC (rev 01) 00:18.0 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] HyperTransport Technology Configuration 00:18.1 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Address Map 00:18.2 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] DRAM Controller 00:18.3 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Miscellaneous Control 00:19.0 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] HyperTransport Technology Configuration 00:19.1 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Address Map 00:19.2 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] DRAM Controller 00:19.3 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Miscellaneous Control 01:01.0 RAID bus controller: 3ware Inc 9550SX SATA-RAID 02:05.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5704 Gigabit Ethernet (rev 10) 02:05.1 Ethernet controller: Broadcom Corporation NetXtreme BCM5704 Gigabit Ethernet (rev 10) 03:00.0 USB Controller: Advanced Micro Devices [AMD] AMD-8111 USB (rev 0b) 03:00.1 USB Controller: Advanced Micro Devices [AMD] AMD-8111 USB (rev 0b) 03:04.0 VGA compatible controller: ATI Technologies Inc Rage XL (rev 27) 03:05.0 Multimedia audio controller: Creative Labs SB Live!
