You can run dmesg in a terminal window, then cut-and-paste into an email.
Or directly into a web browser if you use webmail.

Or plug in a USB stick and dmesg > /mountpoint/filename

You should not have rebooted following that change - it is not permanent.
If you want to make those setting permanent you can do it as part of the kernel options:
The option is    usbcore.use_both_schemes=1

Or you can put those two lines into an init script - probably  /etc/init.d/boot.local

You need to have the kernel source package installed to have those files on your system.
Or just Google for it - there are plenty of examples on the Web.
