Telegesis ETRX3USB modem

I am trying to use X-CTU with a third party USB-Zigbee modem (Telegesis ETRX3USB) to connect to XBee DIO Adapter ZB Pro Int and also XBee 485 without success. Is there any guidance on how to make this work? Are only Digi USB modems supported? I’m new to Zigbee so any guidance would be appreciated.

X-CTU should work with an ETRX3USB but connect at 19200 baud. Otherwise try Telegesis Terminal
