Windows 10: Connecting USB mixer to Win10 PC

Hi.I recently purchased a Rodecater Pro USB mixer.I have connected it to two of my Win 10 laptops without any issue.However when I connect to my PC it doesnt recognise the device. If I go to device manager the the screen constantly refreshes but doesnt show the mixer.I have ensures all Windows updates are installed. If I go to the Bluetooth and other devices screen, under audio it constantly flashes with a few seconds gap rodecaster Pro not installed.Thank you for your help.Andy

XLR microphone + mixer connect to PC

Hello. Recently I bought xlr microphone AT2050 and mixer ALTO ZMX122FX. Got xlr cable and bought some of rca cables for mixer. So the thing is I pluged micro into mixer turned on phantom power plugged in headphones in mixer to test micro before i connect it to pc. So it worked very good and quality and voice effects where superb too.
Ok then i connected rca cable to input for micro into micro slot into motherboard. Micro worked i tested through PC. Then I tried to re ord voice effects but there's where problem started voice effect wasnt not even nearly as good recording it to pc as they sounded straight from mixer as i tested in begining.
So question is what did i do wrong? Do i neef apmlifiler or soundcard to make effects as good and strong as they are when testing mixer without pc. Coz i wanted those effects to apply to my stream on twitch, but they sound terrible when connected to pc. So anything else i need to buy to make em stronger for pc connection. Thanks

P.S.
When i tested it without pc it sounded like MANvsGAME streamer sounds on stream but when i tested through pc voice effects basically arent noticable. So how to make my voice effects sound like his echo reverb sub welcoming feature

Its connected to AUX out what is located on top right corner of mixer. I mean effects are there but they are not so alive and clear as listening directly to mixer.

Where did you connect your output cable on the mixer? Its probably on direct input mode (bypassing all effects applyed on the mixer).
