I installed brltty 4.2.3 and selected PM for Papenmeier.
In the port list I can choose between USB and Com 1 through Com 16.
I assume this means that the Papenmeier driver don't provide any virtual 
ports?

I selected USB from the port list and installed libusb-filter.

Disaster!
The libusb-filter completely broke usb on my Windows 7 machine.
No keyboard, no mouse, no Braille display, no scanner etc...

I'm now up and running again after instructing a sighted person to boot 
into "The last known good configuration" on the advanced boot options menu.
Removed the libusb-filter and rebooted.
All ok.

I am not going to try the filter again :)
