There is at least one big problem showing up in the log. The INQUIRY response indicates a Direct Access type of device (i.e., a disk drive) instead of a CD-ROM type. This may be the result of something going wrong during the initial stages of probing, which were left out of the dmesg log. Apparently the driver thought you had a flash device, not an HP-8200e. Even though dmesg is getting overloaded, you can capture all the debugging messages in the regular system log if you edit /etc/syslog.conf. Tell it to store all levels of kernel messages instead of ignoring DEBUG level messages.
