Gentoo may have reconfigured your system when your USB chipset changed
around, and it hasn't recovered from that.  I would tell you to
apt-get install discover, but you're not running Debian.  Tough luck
:-)

Okay, well, there are several modules that need to be loaded to
support USB mass storage devices.  I can't say for certain which ones
they are and what order they need to be loaded in, but you might want
to look into scsi_mod, ide-scsi, usbcore, usb-uhci, sr_mod, sd_mod,
sg, and usb-storage.  And you may need to mknod the /dev/sd* nodes
again.  And pay attention to /var/log/messages when you plug it in
(tail -f /var/log/messages).
