Well, the first thing to try is to switch to text mode (ctrl-alt-F10) to see the log there, and then attempt to unplug the device. Hopefully you get some messages and can take a photo with a camera.
If you have a real hardware serial port (rs232) you can tell the kernel to dump messages there, and capture them on another computer; this one may use an usb-rs232 converter.
If not, another method is to tell the kernel to send the message via ethernet port to another computer in the LAN.
If you are going to use any of that, I can try dig out my notes and give you more info. I have done both methods, but not recently. It is not point and shoot, unfortunately. Thanks for the hints. Especially the console 10 hint was useful.
One problem with console 10 is, that the Kernel crashes became more unlikely in console 10 compared with crashes when using the X11 display. In X11 the Kernel often crashed, if I unplugged the unused USB DVB device. In console 10 I had to use the device heavily (recording a TV show), until the Kernel crashed reliable every-time I unplugged the USB device. Here is my bug report, if someone is interested: Bug 194171 - em28xx DVB-T2 USB card can't be unplugged and fails to hibernate/resume https://bugzilla.kernel.org/show_bug.cgi?id=194171 I found, that my mainboard has a serial port, but it's not connected to the front or back panel and so currently useless.
