Dear Xiaofan,

as I described in my mail from 3 Oct 2010, I tried libusb-win and
the filter driver  and had no success so long.

Your mail above sounds like this should succeed. Are there different
libusb-win versions out there? Anything I forgot? 

To remind: After installing the filter driver for my devices, TestLIBUSB
listed the devices, but e.g. your libftdi eeprom-new git branch MinGW 32bit
snapshots couldn't access the devices.
