Aten CM0264 KVM misbehaves with Ubuntu: it is apparently misdetected as CD-ROM, causing long delays and all kinds of strange errors, making the KVM all but unusable. (Disconnecting USB cable from it temporarily during boot acts as a workaround, albeit a very inconvenient one.)
This happens with 64-bit 10.04 and 12.04 at least (others not tested).
WORKAROUND: sed '1i\
> SUBSYSTEM=="block", ATTRS{vendor}=="ATEN", GOTO="cdrom_end"' /lib/udev/rules.d/60-cdrom_id.rules >/etc/udev/rules.d/60-cdrom_id.rules
sed '1i\
SUBSYSTEM=="block", ATTRS{vendor}=="ATEN", GOTO="persistent_storage_end"' /lib/udev/rules.d/60-persistent-storage.rules > /etc/udev/rules.d/60-persistent-storage.rules
After those at least "udevadm test /dev/sr1" finishes quickly.
lsusb -v output below. Note in particular 0557:1808 is detected as "mass storage":
