Samsung Galaxy A54 not detecting USB-C mobile controller until it receives charge

I bought a *Gamesir X2s* (mobile controller, similar to adding half an Xbox or PlayStation controller to either side of your phone) recently and have had connectivity issues with my Samsung Galaxy A54. When I plug the Gamesir X2s into my phone, it does not detect it. However, the Gamesir X2s has a USB-C port that can be used for charging the phone through the Gamesir X2s. If I try charging my phone like this, it will detect the Gamesir X2s, and I can unplug charging and the phone will continue to detect the Gamesir X2s with no issues. Presumably, because of capacitors inside of the Gamesir X2s, I can also plug in a charger into it when the phone is not plugged into it, and then take the charger out and plug my phone in, and they will properly connect. I can also unplug the Gamesir X2s from my phone and plug it back in and still have it detected. This seems to work up to about a minute after the Gamesir X2s has been either plugged into a charger or the phone. Is this an issue with the Gamesir X2s, or my Samsung Galaxy A54? And is there any way I can fix this issue (such as changing settings in my phone)? I found that a USB-C male to USB-A female adapter cable, when plugged into my phone, came up as a USB device. I thought this was odd because it is just a cable and not a USB device. However, I also have a USB-A male to USB-C female adapter, and in combination using both adapters and plugging in my Gamesir X2s into my phone, the Gamesir X2s is recognised and receives power. I can then unplug it all and quickly plug the Gamesir X2s directly into my phone and it all works. So I guess I have found a solution, though I'd still like to find the specific root cause of this, if possible.
