Types

type SP_DEVICE_INTERFACE_DATA

type SP_DEVICE_INTERFACE_DATA struct {
	// contains filtered or unexported fields
}

type SP_DEVINFO_DATA

type SP_DEVINFO_DATA struct {
	// contains filtered or unexported fields
}

type SetupDi

type SetupDi struct {
	// contains filtered or unexported fields
}

func NewSetupDi

func NewSetupDi() (*SetupDi, error)

func (*SetupDi) EnumUsbDev

func (sdi *SetupDi) EnumUsbDev(vid uint16, pid uint16) ([]string, error)

port, serial, ???

func (*SetupDi) GetDetailPath

func (sdi *SetupDi) GetDetailPath(hdi uintptr, did uintptr) (string, error)

func (*SetupDi) GetInstanceID

func (sdi *SetupDi) GetInstanceID(hdi uintptr, sdd uintptr) (string, error)

func (*SetupDi) ScanUsbDev
