After upgrade to 4.3.3-300.fc23 or 4.3.3-301.fc23 rt2800usb WiFi dongle can no longer connect to the network. Kernel reports multiple transfer errors after NetworkManager tries to establish network connection. kernel: xhci_hcd 0000:02:00.0: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 2 comp_code 13 kernel: xhci_hcd 0000:02:00.0: Looking for event-dma 00000000d9e59740 trb-start 00000000d9e59720 trb-end 00000000d9e59730 seg-start 00000000d9e59000 seg-end 00000000d9e59ff0 Everything works as expected on kernel 4.2.6-301.fc23 and below. Haven't tried versions in between yet. There was a similar problem in the past (at least error output looks exactly like mine) but code from this patch is still present in latest kernel version shipped by Fedora... https://git.kernel.org/cgit/linux/kernel/git/mnyman/xhci.git/commit/?id=7895086afde2a05fa24a0e410d8e6b75ca7c8fdd
I have similar experiences when using USB 3.0 Edimax AC1200 wifi adapter after updating kernel in FC 23 to 4.3.3-301 It works fine in USB 2.0 under 4.3.3-301 port or in USB 3.0 under 4.2.6-300. It seems that XHCI module is broken.

*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 23 kernel bugs. Fedora 23 has now been rebased to 4.7.4-100.fc23. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 24 or 25, and are still experiencing this issue, please change the version to Fedora 24 or 25. If you experience different issues, please open a new bug report for those.
*********** MASS BUG UPDATE ************** This bug is being closed with INSUFFICIENT_DATA as there has not been a response in 4 weeks. If you are still experiencing this issue, please reopen and attach the relevant data from the latest kernel you are running and any data that might have been requested previously.
Everything is working fine now at least for me and it has been that way for some time, so thank you and sorry for not closing it sooner.
