Component mapper's Buffer I/O not behaving as expected

[atirut-w]

I am developing an OS and had to query information about components in a specific slot, so I used the component mapper's third command with a number argument, but it doesn't seem to behave as expected.

What I did was:

1. Write 3 into Buffer I/O(TSF byte tag)
2. Write component index into buffer
3. Write 3 into Command Status

What happened:

1. The command seems to return nothing

If I write 3, 0, (index) into the buffer, I can only query the component in slot 0.
