Hi,

The issue might be that the BIOS is re-programming the USB device 
somehow. I see the HID descriptor has support for different modes, and 
possible the device is not re-setting its internal state upon 
re-enumeration. You can try:

usbconfig -d X.Y power_off
usbconfig -d X.Y reset

Maybe if you disable USB legacy support in the BIOS it will work.

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

usbconfig dump_device_desc dump_curr_config_desc

When it works and when it doesn't work?

Output from dmesg is also appreciated.

--HPS
