Some clean up of IQ+ frequency control
IQ+  users  on  MS  Windows  should  update  the  driver,  the  PE0FKO
libusb-w32  driver is  obsolete  and not  compatible  with the  latest
libusb user mode  library we are using for control  of this device. By
far the  easiest way  to upgrade,  without loosing  compatibility with
applications using older vendor USB  drivers, is to download the Zadig
tool  from   https://zadig.akeo.ie/,  run  the  tool,   scan  for  all
appropriate USB  devices (check the "Menu->Options->List  All Devices"
option), select the device called  DG8SAQ from the top drop-down list,
then with  WinUSB listed  as the  replacement driver  to right  of the
green arrow, double-click the "Replace libusb-w32" button. After a few
seconds the driver will be replace, quit the utility and you are done.

/* Linux / Windows program to control the frequency of a si570 synthesizer

Under Linux:
-use the linux version of function void si570_sleep(int us)
-compile with
gcc -Wall -o set_si570_freq set_si570_freq.c -lusb -lm
-run with sudo ./set_si570_freq
Under Windows:
-use the windows version of function void si570_sleep(int us)
-compile with mingw
C:\mingw\bin\mingw32-gcc -Wall -o set_si570_freq set_si570_freq.c -lusb -lm
