 I try to enable USB_DEBUG but with all the debug messages the sd-drives 
 aren't discovered at boot time. I will try to add some print lines. The 
 trace is:
 panic: kernel diagnostic assertion "offset < dma->udma_block->size" 
 failed: file "/usr/src/sys/dev/usb/usb_mem.c", line 392 offset 65536 vs
