Ok, so HW itself negotiated HS instead of SS. Note that below ep0 max
packet size is set ot 64.

Would you have a usb sniffer to see if the link even attempts to run Rx
termination detection?
Another thing to try is setting both of the quirks below:
snps,dis_u3_susphy_quirk
snps,dis_u2_susphy_quirk
Gadget debug won't be necessary as it won't bring much new info.
