Thanks for the reply. TinyUSB runs on the microcontroller board; it is the USB stack implementation used by the software on the board. So it doesn't touch the kernel, by definition. It is behaving in some way that is unexpected to the Linux driver, and causing bad behavior on the part of the driver.
It is possible this is a timing or kernel driver state machine. These crashes occur when I reset the board. So the USB device is forcibly disconnected, and then immediately tries to re-enumerate. This is much faster than the usual unplug/replug time you might see, if say, you unplugged a replugged a USB keyboard or USB flash drive. Would a USB trace be helpful to you? I can use a Beagle and get a trace file. Is this the right place to continue discussing this bug, or should it be in some Linux kernel bug system? Thanks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1871143 Title: Kernel crash during USB device enumeration or mounting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1871143/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
