IQ+ users on MS Windows should update the driver, the PE0FKO libusb-w32 driver is obsolete and not compatible with the latest libusb user mode library we are using for control of this device.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
|
|
ON5GN 6 jan 2012
|
|
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
|
|
-run with set_si570_freq.exe
