with usb devices I not having problems, I'm having them with my
monitor, and as I didn't find the problem yet, I thought if this could
be interfering.....
Also note that these are almost certainly PCI devices, even if they're
on-board USB ports. The PCI interface isn't limited to PCI slots! If
'lspci | grep -i uhci' shows your USB controller, then you can be sure
that it is a PCI device...meaning IRQ sharing is much less of a concern.
yes, by doing that order shows me this:
0000:00:10.0 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB
1.1 Controller (rev 81)
0000:00:10.1 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB
1.1 Controller (rev 81)
0000:00:10.2 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB
1.1 Controller (rev 81)
0000:00:10.3 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB
1.1 Controller (rev 81)
So maybe this is not the cause my monitor is working wrong, then,
Thanks and greetins

Hello everyone,
I have read an article, which tells that if you type on a shell this
order: cat /proc/interrupts
and then you see more than one device sharing one irq, and these
devices are not pci or agp, then you may be having a conflict. I did
that and I have 5 devices sharing the same irq, these ones:
17: 0 IO-APIC-level ehci_hcd:usb1, uhci_hcd:usb2, uhci_hcd:usb3,
uhci_hcd:usb4, uhci_hcd:usb5
is there something I can do to these devices have their own irq?
There's probably no need to worry (unless you're having problems with
USB).
It appears that you have a single 5-port USB 2.0 controller on that IRQ,
judging by the usb1-usb5 designations after uhci_hcd (a USB host
controller driver) and the ehci_hcd module (USB 2.0 support module). It
may not even be possible to have the different ports of the USB
controller on different IRQs, if they really are 5 ports on one chip (as
is my guess).
Also note that these are almost certainly PCI devices, even if they're
on-board USB ports. The PCI interface isn't limited to PCI slots! If
'lspci | grep -i uhci' shows your USB controller, then you can be sure
that it is a PCI device...meaning IRQ sharing is much less of a concern.
