Hello world :-)

I have just encountered this problem using external usb dvd recorder. Here is
the dmesg output:

ugen0.13: <Hitachi-LG Data Storage Inc Portable Super Multi Drive> at usbus0
umass0 on uhub1
umass0: <6238--Storage> on usbus0

g_access(961): provider cd0 has error 6 set
g_access(961): provider cd0 has error 6 set
g_access(961): provider cd0 has error 6 set


May be caused by GEOM but also usbconfig hangs and no new devices can be
attached.

Any hints welcome :-)
