USB (internally fixed) card reader questions

Hello,

with 7.2, after I inserted a flash card, I generated a write request to 
the corresponding device (`true > /dev/da1` for example if it was a SD 
card). To change the card I found `camcontrole eject da1` usefull to 
prevent panics.

With -current I can't update the label by `true > /dev/da1`, I get 
"device not configured".
So my question is how do I correctly use flash cards in fixed (USB) card 
readers? Do I still have to use camcontrol eject before removing? How do 
I get hald working with umass devices?
With 7.2, after the second insertion of the same flash card hal jumped 
in and I could mount it with Thunar. UFDs (USB Flash Disks, the "sticks" 
with USB controller) worked just form the start. After pluging in I 
could see the device in Thunar. Both doesn't work under -current any more.

Thanks for any help,

-Harry
