X300 + USB DVD/CDRW + SD Card problem

Dear All!
I have a Dell Latitude X300 with USB DVD/CDRW drive.
When i'm trying to connect the drive i can hear it spinup and see the 
light blinking but got the following in the messages:
Oct 22 17:00:35 latitude kernel: umass0: Dell USB Drive A01, rev 
2.00/1.04, addr 2
Oct 22 17:00:35 latitude kernel: ehci_idone: need toggle update 
status=80018d40 nstatus=80008c80
Oct 22 17:00:35 latitude kernel: umass0: Get Max Lun not supported (STALLED)
Oct 22 17:00:35 latitude kernel: umass0: Phase Error, residue = 0
Oct 22 17:00:37 latitude last message repeated 4 times
The same happend when i do remove the ehci interface from the kernel 
config or when i'm loading umass as a KLD.
It is not the matter of having media presented or not.

In addition, when i do load cbb module it finds two card readers (one is 
PCMCIA, another is SD card reader):
Oct 22 17:09:09 latitude kernel: cbb0: <RF5C476 PCI-CardBus Bridge> at 
device 3.0 on pci2
Oct 22 17:09:09 latitude kernel: cbb1: <RF5C476 PCI-CardBus Bridge> at 
device 3.1 on pci2

But when i try to insert my SD Card (256MB Transcend) i have the following:
Oct 22 17:10:20 latitude kernel: cbb0: PC Card card activation failed

Could someone please show me the right way?

The handbook was searched and read about umass, camcontrol etc.
The OS is FreeBSD latitude 5.3-BETA7 FreeBSD 5.3-BETA7 #3: Thu Oct  7
