I have a new workstation running 64 bits 2.6.34 gentoo sources. It's an
HP p6520y (AthlonIIX4) with 6GB and lsusb reports an Alcor Micro 21-in-1
Flash Card Reader.

I have no usb storage devices plugged in and I see in my dmesg many of
the following messages:

usb-storage: queuecommand called
usb-storage: *** thread awakened.

Any ideas who/what is doing this? How to debug?
