Dear Xiaofan,

I have installed libusb-win as the filter driver . One FT232R and one 
are connected to the system, and after setup TestLIBUSB lists the devices, one
device for the FT232R and 3 devices for the FT2232H. From your
libftdi-1.0_eeprom_24Sept2010_mingw I run "eeprom" to access the FT2232H and
I get the error message
"unable to open ftdi device: -5 (unable to claim usb device. Make sure the
default FTDI driver is not in use)
Running "eeprom -p 0x6001" gives:
"unable to open ftdi device: -4 (usb_open() failed)

Any ideas what I do wrong?
