Created attachment 260655 [details] kernel log, device attach and kernel BUG TEST: Need two machines: server and client From the server, use usbip_host module and share a DigitalPersona Fingerprint Reader ( U.are.U 4500 ) through usbip: #> usbip list -l - busid 2-1.3 (05ba:000a) DigitalPersona, Inc. : Fingerprint Reader (05ba:000a) #> usbip bind -b 2-1.3 usbip: info: bind device on busid 2-1.3: complete On the client, use vhci_hcd module and attach remote reader with: #> usbip attach -r 10.0.2.2 -b 2-1.3 [ 438.590348] vhci_hcd: vhci_device speed not set [ 438.707349] vhci_hcd: vhci_device speed not set (These two lines are not normal...) Try to use the the device with fprint_demo fprint_demo hangs, and the kernel BUG is logged. In attachment: - device attach in kernel.log just before the BUG dump - kernel BUG I've been doing some tests, and this setup works if client machine is on kernel 4.10, so something got broken since...
