Hi,
Looks like your keyboard has bug when it crashes on control requests. You can
try slowing down the set leds request. Edit "src/sys/dev/usb2/input/ukbd2.c",
then lookup:
[UKBD_CTRL_LED] = {
.type = UE_CONTROL,
.endpoint = 0x00, /* Control pipe */
.direction = UE_DIR_ANY,
.mh.bufsize = sizeof(struct usb2_device_request) + 1,
.mh.callback = &ukbd_set_leds_callback,
.mh.timeout = 1000, /* 1 second */
},
Add:
.interval = 10, /* 10 milliseconds */
Try different interval values in the range 10 to 500 ms.
