>Description:
	Some USB memory keys take a very long time to perform some
	initialisation step but otherwise appear to work OK.

	With the problematic keys it takes over a minute between printing:

sd0 at scsibus0 target 0 lun 0: <M-SysT5, Dell Memory Key, 5.00> disk removable

	and printing

sd0: 121 MB, 975 cyl, 128 head, 2 sec, 512 bytes/sect x 249599 sectors

	and then takes a similar length of time to do a mount.
	Once mounted it performs normally.

	Problem has also been seem on 3.99.18 and 3.0 machines.
	
>How-To-Repeat:
	Plug in the wrong sort of USB memory key.
	We've seen this problem with Dell branded 128MB keys that identify
	themselves as:
	<M-SysT5, Dell Memory Key, 5.00>
	whereas other Dell branded 128MB keys <SMART G2, Dell Memory Key, 1.04>
	and <M-SysT5, Dell Memory Key, 5.05> don't have the problem.

	http://mail-index.netbsd.org/netbsd-users/2006/04/15/0000.html gives an
	example of this with a non Dell branded memory key.
