Re: [LAU] setting up hardware priority

From: "Renato" <rennabh(a)gmail.com> $ lspci -v |grep -i "usb controller" -A 2 00:1d.0 USB Controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #1 (rev 02) (prog-if 00 [UHCI]) Subsystem: Acer Incorporated [ALI] Device 0090 Flags: bus master, medium devsel, latency 0, IRQ 23 -- 00:1d.1 USB Controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #2 (rev 02) (prog-if 00 [UHCI]) Subsystem: Acer Incorporated [ALI] Device 0090 Flags: bus master, medium devsel, latency 0, IRQ 19 -- 00:1d.2 USB Controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #3 (rev 02) (prog-if 00 [UHCI]) Subsystem: Acer Incorporated [ALI] Device 0090 Flags: bus master, medium devsel, latency 0, IRQ 18 -- 00:1d.3 USB Controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #4 (rev 02) (prog-if 00 [UHCI]) Subsystem: Acer Incorporated [ALI] Device 0090 Flags: bus master, medium devsel, latency 0, IRQ 16 -- 00:1d.7 USB Controller: Intel Corporation N10/ICH 7 Family USB2 EHCI Controller (rev 02) (prog-if 20 [EHCI]) Subsystem: Acer Incorporated [ALI] Device 0090 Flags: bus master, medium devsel, latency 0, IRQ 23 and 4 physical USB ports on my laptop, but whichever I plug the soundcard into, it's allways seen on the 1d.7 controller, which seems to be the only USB2 and of course the one with the highest IRQ. However, when I try plugging in a USB bluetooth dongle in different physical ports, it's seen on different Controllers by dmesg. So with the dongle I have actually found which physical port is the 1d.3, which is the one with the lowest IRQ, but when I attach the soundcard to it dmesg reports it on 1d.7. How's that possible? BTW is it possible to reassign IRQ somehow on a laptop? As I said previously the IRQ 16 seems to be shared by the video card, and I read that's not good. thanks again to everyone for help so far, renato
