Seems that I'll have to provide more debug info :-)

BTW I tried a vanilla 2.6.8-rc3, and it works.


under 2.6.8-rc3-mm1 and  2.6.8-rc2-mm2 :

hciconfig -a gives nothing.

I have quite same diff ("usb-storage" under -rc3, "ub" under -mm) for my
flash reader, which I tested under neither (I don't have any CF/SD card
here).

It seems that the wrong driver is used under -mm... After reading
bk-usb.patch, I see a new driver ub.c, which I enabled. With
CONFIG_BLK_DEV_UB disabled, 2.6.8-rc3-mm2 works.


So... my guess is that 2.6.8-rc2-mm* was broken, but as everything works
now in 2.6.8-rc3-mm2 it doesn't matter.

As I understand it, there is a bug in BLK_DEV_UB which make it says it
can handle hci devices, which is false. I'll leave BLK_DEV_UB disabled
for now.

Hope it helps,


Thanks for your help Marcel,
  Stephane.
