In /etc/rc.conf I do have moused_enable="YES", but sudo /etc/rc.d/moused status reports
"moused is not running". I assume it is because of missing psm0.

The command usbconfig -d ugen0.3 dump_device_desc reports:
ugen0.3: <product 0x2970 vendor 0x06cb> at usbus0, cfg=0 md=HOST
spd=FULL (12Mbps) pwr=ON (100mA)

bLength = 0x0012
bDescriptorType = 0x0001
bcdUSB = 0x0200
bDeviceClass = 0x0000 <Probed by interface class>
bDeviceSubClass = 0x0000
bDeviceProtocol = 0x0000
bMaxPacketSize0 = 0x0008
idVendor = 0x06cb
idProduct = 0x2970
bcdDevice = 0x0008
