+
+Package go-dcdcusb interfaces with the DCDCUSB power supply from mini-box ([https://www.mini-box.com/DCDC-USB](https://www.mini-box.com/DCDC-USB))
+via USB port and allows you to retrive the status of the power supply
+
+it depends upon GoUSB which in turn depends upon the libusb C library, thus CGO is required for this module
+
+Please see the GoUSB pages for hints on compiling for platforms other than linux
+
+## Sub Packages

+* [cmd](./cmd)
+
+## Examples
+
+```golang
+
+dc := dcdcusb.DcDcUSB{}
+dc.Init()
+if ok, err := dc.Scan(); !ok {
+    log.Fatalf("Scan Failed: %v", err)
+    return
+}
+defer dc.Close()
+for i := 0; i < 100; i++ {
+    ctx, cancel := context.WithTimeout(context.Background(), (1 * time.Second))
+    dc.GetAllParam(ctx)
+    cancel()
+    time.Sleep(1 * time.Second)
+}
+dc.Close()
