Re: kern/44706: USB mouse does not attach at boot

[Christoph Egger <Christoph_Egger%gmx.de@localhost>]

I booted a kernel with EHCI_DEBUG and UHUB_DEBUG.
ehci_debug and uhub_debug are set to debug level 1.

Then in the dmesg at boot I get these message:

ehci_disown: index=2 lowspeed=1
ehci1: handing over low speed device on port 2 to ohci1
ehci_pcd: change=0x04
uhub3: port 2, device disappeared after reset
uhub_explore: status change hub=1 port=2
ehci after reset, status=0x00001005
ehci port 3 reset, status = 0x00001005
ehci after reset, status=0x00001005
ehci port 2 reset, status = 0x00001005
ehci after reset, status=0x00001005
ehci port 2 reset, status = 0x00001005
ehci after reset, status=0x00001005
ehci port 3 reset, status = 0x00001005


When I unplug and replug the USB mouse after boot
then I get these messages:

ehci_disown: index=2 lowspeed=1
ehci1: handing over low speed device on port 2 to ohci1
ehci_pcd: change=0x04
uhub_explore: status change hub=1 port=2
uhub3: port 2, device disappeared after reset
uhub_explore: status change hub=1 port=2
