It's the usual case of fixing one bug triggering another, in your case because the fix ran into a previously unseen hardware bug. One other way to work around that bug would be disabling CONFIG_PM, but I suspect you don't want to go that route... > Here you are.

Your hardware seems to have a bug whereby that doesn't work correctly, making it immediately leave that state. (And the driver messaging is fine for what should be an uncommon event; plus it highlighted your hardware bug.) Notice the "initreset quirk" message -- another bug in that hardware. Workarounds in both cases are simple. When I get a moment, I'll have a patch for you to try. Meanwhile, either workaround I showed above should prevent the attempt to enter that low power mode. - Dave > ohci_hcd: 2005 April 22 USB 1.1 'Open' Host Controller (OHCI) Driver (PCI) > ohci_hcd: block sizes: ed 64 td 64 > ACPI: PCI Interrupt Link [LNKG] enabled at IRQ 11 > ACPI: PCI Interrupt 0000:00:02.0[A] -> Link [LNKG] -> GSI 11 (level, low) -> > IRQ 11 > ohci_hcd 0000:00:02.0: OHCI Host Controller > /home/bor/src/linux-git/drivers/usb/core/inode.c: creating file 'devices' > /home/bor/src/linux-git/drivers/usb/core/inode.c: creating file '001' > ohci_hcd 0000:00:02.0: new USB bus registered, assigned bus number 1 > ohci_hcd 0000:00:02.0: created debug files > ohci_hcd 0000:00:02.0: irq 11, io mem 0xf7eff000 > ohci_hcd 0000:00:02.0: resetting from state 'reset', control = 0x0 > ohci_hcd 0000:00:02.0: enabling initreset quirk > ohci_hcd 0000:00:02.0: OHCI controller state > ohci_hcd 0000:00:02.0: OHCI 1.0, NO legacy support registers > ohci_hcd 0000:00:02.0: control 0x083 HCFS=operational CBSR=3 > ohci_hcd 0000:00:02.0: cmdstatus 0x00000 SOC=0 > ohci_hcd 0000:00:02.0: intrstatus 0x00000044 RHSC SF > ohci_hcd 0000:00:02.0: intrenable 0x8000000a MIE RD WDH > ohci_hcd 0000:00:02.0: hcca frame #0003 > ohci_hcd 0000:00:02.0: roothub.a 01000203 POTPGT=1 NPS NDP=3(3) > ohci_hcd 0000:00:02.0: roothub.b 00000000 PPCM=0000 DR=0000 > ohci_hcd 0000:00:02.0: roothub.status 00008000 DRWE > ohci_hcd 0000:00:02.0: roothub.portstatus [0] 0x00000100 PPS > ohci_hcd 0000:00:02.0: roothub.portstatus [1] 0x00000100 PPS > ohci_hcd 0000:00:02.0: roothub.portstatus [2] 0x00000100 PPS > usb usb1: default language 0x0409 > usb usb1: new device strings: Mfr=3, Product=2, SerialNumber=1 > usb usb1: Product: OHCI Host Controller > usb usb1: Manufacturer: Linux 2.6.17-2avb ohci_hcd > usb usb1: SerialNumber: 0000:00:02.0 > usb usb1: uevent > usb usb1: configuration #1 chosen from 1 choice > usb usb1: adding 1-0:1.0 (config #1, interface 0) > usb 1-0:1.0: uevent > hub 1-0:1.0: usb_probe_interface > hub 1-0:1.0: usb_probe_interface - got id > hub 1-0:1.0: USB hub found > hub 1-0:1.0: 3 ports detected > hub 1-0:1.0: standalone hub > hub 1-0:1.0: no power switching (usb 1.0) > hub 1-0:1.0: global over-current protection > hub 1-0:1.0: power on to power good time: 2ms > hub 1-0:1.0: local power source is good > hub 1-0:1.0: no over-current condition exists > hub 1-0:1.0: state 7 ports 3 chg 0000 evt 0000 > /home/bor/src/linux-git/drivers/usb/core/inode.c: creating file '001' > ohci_hcd 0000:00:02.0: suspend root hub > hub 1-0:1.0: state 7 ports 3 chg 0000 evt 0000, resume root > hub 1-0:1.0: state 7 ports 3 chg 0000 evt 0000 > ohci_hcd 0000:00:02.0: suspend root hub > hub 1-0:1.0: state 7 ports 3 chg 0000 evt 0000, resume root > hub 1-0:1.0: state 7 ports 3 chg 0000 evt 0000 > ohci_hcd 0000:00:02.0: suspend root hub > hub 1-0:1.0: state 7 ports 3 chg 0000 evt 0000, resume root > hub 1-0:1.0: state 7 ports 3 chg 0000 evt 0000 > ohci_hcd 0000:00:02.0: suspend root hub ... etc _______________________________________________ linux-usb-devel@lists.sourceforge.net To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
