Hi, I am experiencing the kernel on PantherPoint still running out of endpoints. It runs into the error case of xhci_reserve_host_control_ep_resources() It seems to me that for whatever reason a HC is reinitialized, the number of active endpoints should be reset to zero. That fixes the issue. What do you think?
