Kernel bisection led to following output: 692763f31fc2b9d12350fb7f4daacb2f35664d3e is the first bad commit commit 692763f31fc2b9d12350fb7f4daacb2f35664d3e Author: Alan Stern <st...@rowland.harvard.edu> Date: Mon Oct 28 10:52:35 2019 -0400
USB: Skip endpoints with 0 maxpacket length -- The output of lsusb in comment #7 shows that an endpoint with address 0x82 shows up twice. First with 'wMaxPacketSize 0x0000 1x 0 bytes', second 'wMaxPacketSize 0x13fc 3x 1020 bytes'. Probably that endpoint is dropped when encountering wMaxPacketSize = 0 and no streaming interface is created. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1861344 Title: uvcvideo: IPEVO Ziggi-HD document camera stops working on kernel 4.4.0-171 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1861344/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
