: 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?
