[Discuss] what does this mean: usb 2-2: reset high-speed USB device number 2 using ehci-pci

[bogstad at pobox.com (Bill Bogstad)]

[It seems like I'm on a roll of odd low level hardware/software
questions recently.]

I've been getting messages in the system log for several years now
like the one in the
subject line.   A new one is typically logged every 1000-4000 seconds.
  The device
in question is a USB multi-card reader on a desktop system.   I've done some web
searching to try to find some info about when that messages is
generated, but have
had no luck.   The device seems to work fine so it has never been a
pressing issue.   I would just like to understand what is going on.
Any ideas?

Thanks,
Bill Bogstad
