The driver isn't = very good at telling apart certain valid and invalid events, it just logs them a= ll. Mouse interrupt endpoint has an URB at 1267010, cycle bit 1 as expected. 0 0x0000000001267000: Buffer 0000000000000000 length 0 TD size 0 intr 0 ty= pe 'No-Op' flags b:i:i:c:s:i:e:C 0 0x0000000001267010: Buffer 000000000125e700 length 10 TD size 0 intr 0 t= ype 'Normal' flags b:i:I:c:s:I:e:C Cancellation commands, Set TR Dequeue to 1267010 with cycle 1. 0 0x0000000001201950: Stop Ring Command: slot 7 sp 0 ep 3 flags C 0 0x0000000001201960: Set TR Dequeue Pointer Command: deq 0000000001267011 stream 0 slot 7 ep 3 flags C Their completion events have been overwritten by SuperSpeed device activity, but no sign of problems was seen in logs.

BTW, I see that the endpoint of interest has 1ms interval too, longer inter= val is on the second endpoint of this mouse. IDK if it matters anyway. If you would like to play with intervals, see drivers/usb/host/xhci-mem.c function xhci_parse_frame_interval(). Replace ep->desc.bInterval with any number like 1 or 10, units are milliseconds. Leave *8 unchanged. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
