At some points the connection to devices connected through USB 3 ports stops working. I get these warnings: [ 7503.933301] usb 3-4: usb_probe_device [ 7503.933308] usb 3-4: configuration #1 chosen from 3 choices [ 7503.933335] usb 3-4: ep 0x82 - rounding interval to 16 microframes [ 7503.933344] usb 3-4: ep 0x87 - rounding interval to 256 microframes [ 7503.933359] usb 3-4: ep 0x89 - rounding interval to 256 microframes [ 7503.934054] usb 3-4: Successful Endpoint Configure command [ 7503.934644] xhci_hcd 0000:0f:00.0: WARN: short transfer on control ep [ 7503.934778] usb 3-4: adding 3-4:1.0 (config #1, interface 0) [ 7503.935020] xhci_hcd 0000:0f:00.0: WARN: short transfer on control ep [ 7503.935211] usb 3-4: adding 3-4:1.1 (config #1, interface 1) [ 7503.935241] usb 3-4: adding 3-4:1.2 (config #1, interface 2) [ 7503.935271] usb 3-4: adding 3-4:1.3 (config #1, interface 3) [ 7503.935520] xhci_hcd 0000:0f:00.0: WARN: short transfer on control ep [ 7503.935727] usb 3-4: adding 3-4:1.4 (config #1, interface 4) [ 7503.936017] xhci_hcd 0000:0f:00.0: WARN: short transfer on control ep [ 7503.936190] usb 3-4: adding 3-4:1.5 (config #1, interface 5) [ 7503.936394] xhci_hcd 0000:0f:00.0: WARN: short transfer on control ep [ 7503.936547] usb 3-4: adding 3-4:1.6 (config #1, interface 6) [ 7503.936805] xhci_hcd 0000:0f:00.0: WARN: short transfer on control ep [ 7503.936915] usb 3-4: adding 3-4:1.7 (config #1, interface 7) [ 7503.937273] xhci_hcd 0000:0f:00.0: WARN: short transfer on control ep [ 7503.937469] usb 3-4: adding 3-4:1.8 (config #1, interface 8) [ 7503.937655] xhci_hcd 0000:0f:00.0: WARN: short transfer on control ep [ 7503.937810] usb 3-4: adding 3-4:1.9 (config #1, interface 9) [ 7503.938270] xhci_hcd 0000:0f:00.0: WARN: short transfer on control ep [ 7503.938472] usb 3-4: adding 3-4:1.10 (config #1, interface 10) [ 7503.938499] drivers/usb/core/inode.c: creating file '004' [ 7504.114044] cdc_ether 3-4:1.9: usb_probe_interface [ 7504.114047] cdc_ether 3-4:1.9: usb_probe_interface - got id [ 7504.114332] usb 3-4: Successful Endpoint Configure command [ 7504.114903] xhci_hcd 0000:0f:00.0: WARN: short transfer on control ep [ 7504.115277] xhci_hcd 0000:0f:00.0: WARN: short transfer on control ep [ 7504.115856] cdc_ether 3-4:1.9: usb0: register 'cdc_ether' at usb-0000:0f:00.0-4, CDC Ethernet Device, 92:44:10:1c:ec:cf [ 7504.115871] usbcore: registered new interface driver cdc_ether [ 7504.308793] xhci_hcd 0000:0f:00.0: WARN: short transfer on control ep [ 7504.309161] xhci_hcd 0000:0f:00.0: WARN: short transfer on control ep [ 7504.309534] xhci_hcd 0000:0f:00.0: WARN: short transfer on control ep [ 7504.309988] xhci_hcd 0000:0f:00.0: WARN: short transfer on control ep [ 7504.310416] xhci_hcd 0000:0f:00.0: WARN: Stalled endpoint [ 7515.227903] usb0: no IPv6 routers present

Ok, will do. Actually, I have my doubts that the syslog posted actually corresponded to a hang. I will wait until I experience another one and am sure.
All USB bugs should be sent to the linux-usb@vger.kernel.org mailing list, and not entered into bugzilla. Please bring this issue up there, if it is still a problem in the latest kernel release.
