stm32nucleo/stm32f072: `modprobe -r; modprobe` cycle results in `Couldn't send data format (err=-110)` on imx6

[marckleinebudde]

Just stumbled over a strange problem, I'm not going to debug now.

• stm32nucleo board with stm32f072
• board is powered by USB-Hub
• USB is connected with imx6 riot board
• Linux: current net-next/main d954a67a7dfa ("ipv4: fib_rule: Move fib4_rules_exit() to ->exit().")
• FW: 19f3c5f ("Merge pull request Add board profile for Jhoinrch RH02 #297 from nullstalgia/rh02")
• modprobe -r gs_usb; modprobe gs_usb fails after 2..3 cycles

Jun 17 13:26:07 riot kernel: gs_usb 2-1.4:1.0: Couldn't send data format (err=-110)                                            Jun 17 13:26:07 riot kernel: gs_usb 2-1.4:1.0: probe with driver gs_usb failed with error -110

• with an additional candlelight adapter it seems to work
