Hey all, was searching for an answer to my problem and finally solved it and wanted to share here for others having the same issue. (I've seen a few posts having the same issue but are very old, hopefully this helps someone out that has the same issue. )
I have 2 version 3 dongles from rtl-sdr.com and was trying to get unitrunker working with both. They each indivdually worked when tested in SDR# and unitrunker so I knew they were both working fine, but whenever I plugged both into unitrunker one would not work.
Many posts online said that it's likely a USB Hub issue or a built-in Hub in your laptop. Not wanting to give up, I continued searching and found out that they have the same serial number, so I used rtl_eeprom (Instructions here: Ubuntu Manpage: rtl-eeprom - EEPROM programming tool for RTL2832 based DVB-T receivers) to reprogram the serial number from 00000001 to 00000002 on one of my devices, and now they both work wonderfully in unitrunker.
Although, in my quest to get it working, I descovered SDRTrunk, and I love that way better than the harder to manage unitrunker, and I believe the SDRTrunk does a better job decoding P25 than DSD+, and the alias funtion, onced programmed is brilliant for seeing who is speaking and blocking out unwanted talkgroups (I'm sure there are ways to do this in unitrunker but it seems much harder, plus watching the waterfall and spectrum live is nice to see as well), so it's my go-to now.
Hopefully this helps someone having a similar issue. Have a great one!
