Hello, at first I thought I had found a regression in CURRENT (2020-01-19), and now I'm not so sure since, before reporting I rolled back a recent BIOS upgrade and that got rid of the issue. First of all, the hardware: Lenovo ThinkPad A485 (AMD Ryzen processor). The issue (BIOS v1.28[1]) being that any USB device: would work on first plug, but if unplugged and plugged again, it wouldn't work (see dmesg below). Downgrading to BIOS v1.24 results in the issue disappearing. How should this be dealt with? Could this be something FreeBSD needs better support for? or is it entirely on Lenovo? If the former, how can I help provide more information/testing(*)? If the latter, should I inform Lenovo of the issue? If anyone has experience with that, I'd appreciate pointers as to how to provide them with information in a way that makes it somewhat likely that things get solved. [1]: BIOS Release notes: https://download.lenovo.com/pccbbs/mobiles/r0wuj60w.txt (*): Helping spot bugs and provide information/testing is why I'm running CURRENT after all Just FTR: I also experienced random kernel panics [2] with versions v1.22 and v1.16 of the BIOS, so maybe Lenovo is being unreasonable/unreliable about BIOS upgrades. In any case I am curious as to how other OS deal with this class of issues and how FreeBSD could (if possible at all) work better in these cases. [2]: Kernel panic solved by BIOS upgrade (to v1.24) see: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=239351 Also FTR, this was the contents of dmesg with BIOS v1.28 and CURRENT as of 2020-01-19: (notice there are multiple disconnect and reconnect attempts of different devices) ugen1.2: <ALCOR USB Hub 2.0> at usbus1 (disconnected) uhub4: at uhub1, port 1, addr 1 (disconnected) ugen1.3: <BTC USB Multimedia Keyboard> at usbus1 (disconnected) ukbd0: at uhub4, port 2, addr 2 (disconnected) ukbd0: detached uhid0: at uhub4, port 2, addr 2 (disconnected) uhid0: detached ugen1.4: <ALCOR USB Hub 2.0> at usbus1 (disconnected) uhub5: at uhub4, port 4, addr 3 (disconnected) ugen1.5: <SteelSeries SteelSeries Rival 310 eSports Mouse> at usbus1 (disconnected) uhid1: at uhub5, port 1, addr 4 (disconnected) uhid1: detached ums0: at uhub5, port 1, addr 4 (disconnected) ums0: detached ukbd1: at uhub5, port 1, addr 4 (disconnected) ukbd1: detached uhub5: detached uhub4: detached ugen1.2: <ALCOR USB Hub 2.0> at usbus1 uhub4 on uhub1 uhub4: <ALCOR USB Hub 2.0, class 9/0, rev 2.00/7.02, addr 1> on usbus1 acpi_ec0: EcCommand: no response to 0x84 uhub4: 4 ports with 4 removable, self powered acpi_ec0: EcCommand: no response to 0x84 acpi_ec0: EcCommand: no response to 0x84 acpi_ec0: GPE query failed: AE_NO_HARDWARE_RESPONSE usbd_setup_device_desc: getting device descriptor at addr 2 failed, USB_ERR_TIMEOUT usbd_setup_device_desc: getting device descriptor at addr 2 failed, USB_ERR_TIMEOUT usbd_setup_device_desc: getting device descriptor at addr 2 failed, USB_ERR_TIMEOUT usbd_setup_device_desc: getting device descriptor at addr 2 failed, USB_ERR_TIMEOUT usbd_setup_device_desc: getting device descriptor at addr 2 failed, USB_ERR_TIMEOUT ugen1.3: <Unknown > at usbus1 (disconnected) uhub_reattach_port: could not allocate new device ugen1.2: <ALCOR USB Hub 2.0> at usbus1 (disconnected) uhub4: at uhub1, port 1, addr 1 (disconnected) uhub4: detached usbd_setup_device_desc: getting device descriptor at addr 1 failed, USB_ERR_TIMEOUT usbd_setup_device_desc: getting device descriptor at addr 1 failed, USB_ERR_TIMEOUT usbd_setup_device_desc: getting device descriptor at addr 1 failed, USB_ERR_TIMEOUT usbd_setup_device_desc: getting device descriptor at addr 1 failed, USB_ERR_TIMEOUT usbd_setup_device_desc: getting device descriptor at addr 1 failed, USB_ERR_TIMEOUT ugen1.2: <Unknown > at usbus1 (disconnected) uhub_reattach_port: could not allocate new device usbd_setup_device_desc: getting device descriptor at addr 1 failed, USB_ERR_TIMEOUT usbd_setup_device_desc: getting device descriptor at addr 1 failed, USB_ERR_TIMEOUT usbd_setup_device_desc: getting device descriptor at addr 1 failed, USB_ERR_TIMEOUT usbd_setup_device_desc: getting device descriptor at addr 1 failed, USB_ERR_TIMEOUT -- Evilham
