Ok. Interesting.

I found some bugs in "ata-usb.c" which I have now fixed and committed to SVN. 
You still cannot do "atacontrol attach ata2" nor "atacontrol detach ata2" on 
USB devices. I hope that SOS can fix this.

Could you have done a "svn update", then re-copy "ata-usb.c" to 
"/usr/src/sys/dev/ata/", then rebuild your kernel and try again?

In "ata-usb.c" there is a variable, "atausbdebug" which you can set non-zero 
to enable debugging, if the driver does not work.

--HPS
