            Bug ID: 208843
           Summary: System freeze and hard reset when attempting to flash
                    Sparkfun Red-V
           Product: Drivers
           Version: 2.5
    Kernel Version: 5.4.48-gentoo
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: USB
          Assignee: drivers_usb@kernel-bugs.kernel.org
          Reporter: michael@michaelkloos.com
        Regression: No

The Sparkfun Red-V appears as a flash drive and 2 ACM modems (UARTs).  When an
ihex file is copied to the "flash drive", the Red-V resets as it uses that file
to reflash it's SPI flash.  Every 4-5 times I attempt this procedure, the
sudden disconnection of the device causes my host system to freeze for a second
or 2 and then hard-reset.  I wish I could give more technical info, but I'm not
a kernel dev.  If you need more info, let me know and I'll try to get it for
you.
