    SubjectACPI S3 - USB resume problem (kernel 2.6.7)
    Date
    Hello,

    I tried to get S3 "Suspend to RAM" working. Almost everything works now, but
    USB doesn't respond after resuming (kernel 2.6.7).

    The log shows (log appended; lspci -v output also):

    usb 1-1: control timeout on ep0out
    uhci_hcd 0000:00:10.0: Unlink after no-IRQ? Different ACPI or APIC settings
    may help.
    usb 1-1: control timeout on ep0out
    usb 1-1: device not accepting address 2, error -110
    usb 1-1: new low speed USB device using address 3
    usb 1-1: control timeout on ep0out
    usb 1-1: control timeout on ep0out
    usb 1-1: device not accepting address 3, error -110

    Noticed that in /proc/interrupts the values for uhci_hcd are not incremented
    after resume. So are no IRQs where received (is that right ?).
    What could be reason ?

    So far I tried:
    - set CONFIG_USB_DEBUG = y
    - disable/enable APIC as suggested
    ("Unlink after no-IRQ? Different ACPI or APIC settings" goes away, timeout
    stays)
    - disabled USB 1.1 Controller or USB 2.0 Controller in BIOS
    - disabled preemption
    - compiled USB-stuff into kernel instead using as modules
    ( even tried to unload before suspend and reloaded after resume )
    - ensured CONFIG_PM is on and resume/suspend in is
    called /drivers/usb/host/uhci-hcd.c
    - forced reset_hc(uhci) in uhci_suspend() instead of suspend_hc()
    ( comment says it's for some broken motherboards )
    - I saw CONFIG_USB_SUSPEND in some source files under host and core.
    I enabled it directly in these files and recompiled/restarted. No success.
    (doesn't harm, but seems not ready to use:
    - it's not configureable ;)
    - usb_suspend/resume_device() functions are nowhere)

    Nothing helped :/
    Still timeout messages and no USB device works after resume.

    Anybody any idea where to look next or what to search for, or even a fix ?
    If you want more infos I will tell you :)

    Regards,
    Carsten
