+
+## Methods
+
+### NewVmAddUserDevice
+
+`func NewVmAddUserDevice(socket string, ) *VmAddUserDevice`
+
+NewVmAddUserDevice instantiates a new VmAddUserDevice object
+This constructor will assign default values to properties that have it defined,
+and makes sure properties required by API are set, but the set of arguments
+will change when the set of required properties is changed
+
+### NewVmAddUserDeviceWithDefaults
+
+`func NewVmAddUserDeviceWithDefaults() *VmAddUserDevice`
+
+NewVmAddUserDeviceWithDefaults instantiates a new VmAddUserDevice object
+This constructor will only assign default values to properties that have it defined,
+but it doesn't guarantee that properties required by API are set
+
+### GetSocket
+
+`func (o *VmAddUserDevice) GetSocket() string`
+
+GetSocket returns the Socket field if non-nil, zero value otherwise.
+
+### GetSocketOk
+
+`func (o *VmAddUserDevice) GetSocketOk() (*string, bool)`
+
+GetSocketOk returns a tuple with the Socket field if it's non-nil, zero value otherwise
+and a boolean to check if the value has been set.
+
+### SetSocket
+
+`func (o *VmAddUserDevice) SetSocket(v string)`
+
+SetSocket sets Socket field to given value.
