That's because a kernel command line option has no affect on kernel
modules. This would be more proper by doing:

- sudo vi /etc/modprobe.d/usb-core-options
- Add a line with "options usbcore autosuspend=0", without quotes
- sudo update-initramfs -u

Reboot, and hopefully things will work as expected.
