Default usb-storage errors in dmesg

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.
usb-storage: Command TEST_UNIT_READY (6 bytes)
usb-storage: 00 00 00 00 00 00

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

I'd guess, at a glance, that you have CONFIG_USB_STORAGE_DEBUG set in
your kernel config.

To check if that's it (assuming you have /proc/config.gz enabled) run:
# zgrep CONFIG_USB_STORAGE_DEBUG /proc/config.gz
