Comment 13 for bug 1678477

I'm using the keyboard using Ubuntu 17.04 stock kernel with an external, independent powered, usb 2.0. It has a 3.0 Ampere power supply, not so big for these days, but powerful enough to avoid power problems for this keyboard.
I'm using it for a while, several reboots and power-cycles, and I haven't had any error in dmesg, yet.
It seems to confirm that it is a problem of power management on usb ports...
