It is here!! :-)

On the "desc:" in place of ugen I would put "Silicon Labs CP2102N USB
to UART Bridge Controller" as the ugen is in the HWID/LOCATION or
there is a reason to put ugen there? :-)

ugen0.9: <Silicon Labs CP2102N USB to UART Bridge Controller> at
usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (100mA)

  bLength = 0x0012
  bDescriptorType = 0x0001
  bcdUSB = 0x0200
  bDeviceClass = 0x0000  <Probed by interface class>
  bDeviceSubClass = 0x0000
  bDeviceProtocol = 0x0000
  bMaxPacketSize0 = 0x0040
  idVendor = 0x10c4
  idProduct = 0xea60
  bcdDevice = 0x0100
  iManufacturer = 0x0001  <Silicon Labs>
  iProduct = 0x0002  <CP2102N USB to UART Bridge Controller>
  iSerialNumber = 0x0003  <1a2626680675eb11955981afb7be2ba5>
  bNumConfigurations = 0x0001

Thank you!! :-)
