Sadly, there is no such thing in the BIOS of this computer (an Acer Aspire VN7-791G). The only legacy thing in this BIOS is to choose between UEFI (which I'm using) and the older CSM. I cannot see anything related to USB in this BIOS other than in the boot order and in that case I can only choose the boot order of USB storage devices. > > > BTW: The log you sent appears to be from a USB keyboard only device and > not a USB mouse! > > Also try: > > kldload ums > > Can you send output from: > > usbconfig show_ifdrv Here is the output of usbconfig show_ifdrv: ugen0.1: <XHCI root HUB 0x8086> at usbus0, cfg=0 md=HOST spd=SUPER (5.0Gbps) pwr=SAVE (0mA) ugen0.1.0: uhub0: <0x8086 XHCI root HUB, class 9/0, rev 3.00/1.00, addr 1> ugen1.1: <EHCI root HUB Intel> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA) ugen1.1.0: uhub1: <Intel EHCI root HUB, class 9/0, rev 2.00/1.00, addr 1> ugen2.1: <EHCI root HUB Intel> at usbus2, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA) ugen2.1.0: uhub2: <Intel EHCI root HUB, class 9/0, rev 2.00/1.00, addr 1> ugen0.2: <USB2.0-CRW Generic> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA) ugen1.2: <product 0x8008 vendor 0x8087> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA) ugen1.2.0: uhub3: <vendor 0x8087 product 0x8008, class 9/0, rev 2.00/0.05, addr 2> ugen2.2: <product 0x8000 vendor 0x8087> at usbus2, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA) ugen2.2.0: uhub4: <vendor 0x8087 product 0x8000, class 9/0, rev 2.00/0.05, addr 2> ugen0.3: <product 0x2970 vendor 0x06cb> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (100mA) ugen0.3.0: uhid0: <vendor 0x06cb product 0x2970, class 0/0, rev 2.00/0.08, addr 2> ugen0.4: <HD WebCam Chicony Electronics Co.,Ltd.> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA) > > > usbconfig dump_device_desc dump_curr_config_desc > > > When it works and when it doesn't work? When the touchpad is not working, here is the output of usbconfig dump_device_desc dump_curr_config_desc: https://www.dropbox.com/s/utllovfkamnqi9p/usbconfig_dump_device_desc_curr_config_desc_not_working.txt?dl=0 Now, I connected the external USB receiver and rebooted the system. Now, because the external device is connected, the touchpad works just fine. Here is the output of usbconfig dump_device_desc dump_curr_config_desc: https://www.dropbox.com/s/r3pnqsk9aul1z8e/usbconfig_dump_device_desc_curr_config_desc_working.txt?dl=0 > > > Output from dmesg is also appreciated. Output of the verbose boot messages without the external mouse: https://www.dropbox.com/s/ukpoyg6rsl3jjgd/dmesg_without_external_usb.txt?dl=0 Output of the verbose boot messages with the external mouse: https://www.dropbox.com/s/uga7p5zlxh7knsj/dmesg_with_external_usb.txt?dl=0 > Can you run: > > sysctl hw.usb.ums.debug=15 > > Then re-run the "usbconfig -d X.Y reset" and send resulting dmesg? If I run sysctl.hw.usb.ums.debug=15 without the external USB device, sysctl returns: sysctl: unknown oid 'hw.usb.ums.debug': No such file or directory. I decided to go ahead and run the other commands (usbconfig -d 0.3 reset) and post the resulting messages from dmesg: uhid0: at uhub0, port 7, addr 2 (disconnected) hid_get_item: Number of items truncated to 255 uhid0: <vendor 0x06cb product 0x2970, class 0/0, rev 2.00/0.08, addr 2> on usbus0 hid_get_item: Number of items truncated to 255 hid_get_item: Number of items truncated to 255 hid_get_item: Number of items truncated to 255 random: harvesting attach, 8 bytes (4 bits) from uhid0 Full output from lsusb without the external usb receiver: Bus /dev/usb Device /dev/ugen0.4: ID 04f2:b474 Chicony Electronics Co., Ltd Bus /dev/usb Device /dev/ugen0.3: ID 06cb:2970 Synaptics, Inc.
