hi list,
there is a logical problem with pc_keyb.c. if setting the leds does not work the keyboard will no longer exists.
attention:
pckbd_leds() is also know as kbd_leds() what is used quit often !
This is a quick fix ! (read: no real solution !)
some comments from my side:
1. the kbd_exists stuff is not realy documented. I should be removed or explaind properly.
2. the next better way is to check for the returncode from
send_data() and send kbd_exists accordingly.
3. kdb_rate works the same way but does not set kbd_exists
