I'm having a similar issue after an uninstall and reinstall of Oculus home version 27 installed. About every minute of gameplay the USB link is dropped. When the USB is connected and I run the USB test tool I'm getting approximately 850 megabits per second. Before update 27 I was consistently getting over 2 gigabits per second.
I also put in a ticket with oculus so if they give me a fix that works ill let you know I don't understand it I'm using a laptop with 64g of ram and a nVidia 2080 super I shouldn't have any issues I'm wondering if it's a faulty cord but I didn't have this problem before so it just doesn't make much sense to me
