Same thing on the good bus. EP 0 stall is just some control request unsuppo= rted by the device. More interesting is interrupt endpoint 0x81 aka "ep 2". But little happens here. The initial Stopped events on ep 2 and 4 are proba= bly xhci_endpoint_reset(), then EP 0 stalls twice more and then usbhid cancels = some URB from the interrupt endpoint. Does this cancellation go away when you enable the udev rule or ALWAYS_POLL? Maybe something goes wrong here. Then there is nothing, which means that URBs are completing successfully or= not at all (as the mouse doesn't work, probably the latter). At some point disconnection and cancellation again, which proves that there was some URB = on the endpoint at the time. > But then this appears: > > xhci_hcd 0000:0a:00.0: Split transaction error for slot 3 ep 2 > > xhci_hcd 0000:0a:00.0: Hard-reset ep 2, slot 3 >=20 > Shortly after, the mouse disconnects: > > usb 3-1.1: USB disconnect, device number 5 I/O errors aren't entirely uncommon when a device disconnects. Does it mean that the device kept disconnecting by itself and it wasn't you doing it? Do you have some other USB 2.0/3.0 hub you could put between the monitor and the mouse? Does it make any difference? --=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.=
