It is notable to see so much Fujitsu Siemens hardware affected.
I have the same issue with the onboard USB 2.0 of a Fujitsu Siemens P710 E90+ Intel i5 3470 desktop computer.

The problem occurs with any of my Varmilo VA88M keyboards, but not with a Cherry Cymotion G-224. The Varmilo keyboards work perfectly fine on any other desktop computer I tested but which happened to be not of the Fujitsu brand.

However, only on the Fujitsu Siemens P710, both Varmilo keyboards would very often, but not always, stuck and repeat key combinations like Ctrl+C. This never happened in combination with the Cherry keyboard. So it seems, reproducibility of this issue depends on both the computer and the keyboard hardware.

Fed up with this behaviour, I recently installed a NEC USB 2.0 card in its single conventional PCI slot. The problem never reoccurred over the span of two weeks now.
