Hello,
Ive got a weird problem haunting me from time to time, and its been awhile
since I had this problem now but a couple of days ago it resurfaced again. It
went away sometimes with the 2.6.7 - 2.6.8 kernels and surfaced now again
with 2.6.11.
Its a USB Card reader connected to an onboard USB connector, which sometimes
fails to initialize properly. If it for some reason fails to initialize, it
will continue to fail on consecutive reboots / cold starts.
And once its failed to initialize, the only solution I have found is to unplug
the onboard connector and reconnect it while the computer is running. This
will make it initialize correctly, and it will also continue to initialize
correctly after reboot / cold starts.
I know this probably sounds like a HW-problem with the card reader, but I
thought Id post the dmesg logs showing the messages when I unplug the
cardreader and replug it while the computer is running. It might possibly
give some clues if this is a flaw in the kernel or HW. (There are actually
two onboard USB connectors, so that is the reason why in the logs below its
sometimes shown as usb2 and sometimes usb3 depending on what port I plugged
it into - I tried both).
Also, one practical question. If the cardread fails to initialize, is there
any way I can try to reinitialize it without physically unplugging/replugging
the onboard connector? Its not very practical opening the case each time this
happens...
Thanks for any feedback!
