https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=262882 --- Comment #95 from Mark Millard <marklmi26-fbsd@yahoo.com> --- (In reply to Mark Millard from comment #86) The messages that I've reported getting for USB 3.1 ports when the NVMe SSD USB3 devices are plugged in: uhub_reattach_port: port 2 U1 timeout failed, error=USB_ERR_IOERROR uhub_reattach_port: port 2 U2 timeout failed, error=USB_ERR_IOERROR seem to be tied to code that looks like (U1 case shown): case C(UR_SET_FEATURE, UT_WRITE_CLASS_OTHER): i = index >> 8; index &= 0x00FF; if ((index < 1) || (index > sc->sc_noport)) { err = USB_ERR_IOERROR; goto done; } port = XHCI_PORTSC(index); v = XREAD4(sc, oper, port) & ~XHCI_PS_CLEAR; switch (value) { case UHF_PORT_U1_TIMEOUT: if (XHCI_PS_SPEED_GET(v) != 4) { err = USB_ERR_IOERROR; goto done; } So it seems to be not getting the speed-mode it expects and it treats that as an error status. I've no clue if the speed-mode should be guaranteed as the code suggests at the point of plugging an NMVe SSD into a USB 3.1 port or not. But it sure looks like a distinct issue from the original buzilla submittal. -- You are receiving this mail because: You are the assignee for the bug.
