you are not alone with this problem. It only happens 2.6.27 kernels. 
Looks like it does not reconnect device in the USB-bus as it should. I 
don't have access to 2.6.27 kernel yet, so I cannot examine it more. 
Hopefully there is someone who could fix that soon... I think good place 
to test fix is add some sleep (msleep(100)) before/after RECONNECT_USB 
-command around line 685 in af9015.c file. The other solution could be 
to remove whole RECONNECT_USB (after firmware download) and set 
no_reconnect -flag.
