work one webcam out of two webcam connect to xhci controller for 2 usb3.0 ports
*Hi Team,* *Good Morning/Afternoon/Evening.* I connect two usb webcameras and one mouse, one keyboard to xhci controller, which has 4 usb v3.x ports. Here, keyboard and mouse works fine without any issue. But out of two cameras, only one camera works( I mean when I click preview only one camera show and one camera show blank ) *Debug log:* kernel: xhci_ep_clear_stall: <3057.043240> -------------------------- xhci_configure_reset_endpoint ------------ <3057.043272> ------------------------>dev:11,bEndpointAddress:81,ep_status:0,epno:3,xfer:0xfffffe0036ebc148 <3057.043296> xhci_cmd_configure_ep: <3057.043545> xhci_check_command: Received command event <3057.289866> xhci_timeout: xfer=0xfffffe0036ebc148 <3057.290055> -------------------------- xhci_configure_reset_endpoint ------------ <3057.290079> ------------------------>dev:11,bEndpointAddress:81,ep_status:0,epno:3,xfer:0xfffffe0036ebc148 <3057.290102> xhci_cmd_reset_ep: <3057.290145> xhci_check_command:Received command event <3057.290198> [ERROR] - xhci_configure_reset_endpoint: Could not set dequeue ptr for endpoint 3, 0 <3057.290221> xhci_cmd_set_tr_dequeue_ptr: <3057.290282> xhci_check_command: Received command event [ERROR] - xhci_configure_reset_endpoint: Error to set dequeue ptr for endpoint 3, 81, err 18, 0 <3057.290350> xhci_cmd_evaluate_ctx: <3057.290403> xhci_check_command: Received command event kernel: <> xhci_timeout: xfer=0xfffffe0036ebc148 It is great if you provide some inputs.

lemme ask some obvious questions: - both cameras work one at a time ? - does order of plugin affect which one blanks ? - are they both the same camera model ? - can you borrow a 3rd camera ?
