Of course that is what I did...

The solution most found is to modify /usr/src/sys/cam/scsi/scsi_da.c with adding
something like this :

		{T_DIRECT, SIP_MEDIA_REMOVABLE, "GENERIC", "USB DISK DEVICE",
		"*"}, /*quirks*/ DA_Q_NO_SYNC_CACHE
	},
	{
		/*
		 * Time DPA20B 1GB MP3 Player
		 * PR: usb/81846
		 */
		{T_DIRECT, SIP_MEDIA_REMOVABLE, "USB2.0*", "(FS) FLASH DISK*",
		"*"}, /*quirks*/ DA_Q_NO_SYNC_CACHE
	},

The only thing is, that code is allready in my 6.1-PRERELEASE code, so no need
to add it again. I was hoping a "Generic usb device" should do the trick.

Another solution was to add "device		udbp		# USB Double Bulk Pipe devices" to
the kernel. Which is by default commented out in the Generic kernel. I
decommented and rebuild my kernel. Still no luck...

But I admit that I didn't check and test all 2.430 results that Google found. I
hoped to get a better answer here.
