In general, this should work. I haven't tested that because I have no
hardware available, but I got some reports, that it works at least
from the days, where this code runs in kernelspace as pt_drv module.
Maybe you try this also.
Could you please send me the debug output of a scan? Just for
curiosity, what scanner is reported.
