 : Hi,
 : 
 : Maybe the AutoInstall CD detecter is interfering with your device.
 
 Hmmm...
 
 : Can you use "usbconfig" to dump the device and config descriptors of your CD 
 : device?
 
 How?
 
 : You can also try:
 : 
 : kldload usb2_quirk
 : usbconfig add_dev_quirk_vplh <vid> <pid> <lo_rev> <hi_rev> UQ_CFG_INDEX_0
 
 What the heck are these different fields?  vid, pid, etc?
