Hi Takashi,

Thanks for your time, and agreed. The host should have seen the
disconnect and on xHCI it does. The Pi uses the downstream dwc_otg
host driver, so I'll first check whether mainline dwc2 has the same
problem and take it to the Raspberry Pi kernel or to linux-usb
depending on that.

Sorry for the noise: I sent a v2 yesterday, fixing the review bot's
findings, before I had seen your reply. Please disregard it.

Regards,
Stjepan
