| 12. | I see a " Universal Serial Bus Controller " and a " USB Virtualization " drop-down-list, both already open.
|
| 13. | All communication on the bus is under the control of the Bus Controller using commands from the BC to the RTs to receive or transmit.

| 14. | The Bus Controller receives RT2's status word and sees that the receive command and data have been received and actioned without a problem.

| 15. | This allows the Backup Bus Controller to " hit the ground running ", if it is called upon to become the active Bus Controller.

| 17. | Large VAX systems primarily used the Hierarchical Storage Controller ( HSC ) series but Unibus and BI Bus controllers to SDI were built as well.
|
| 18. | This means that during a transfer, all communication is started by the Bus Controller, and a terminal device cannot start a data transfer on its own.
|
| 19. | I've also seen this happen because of a faulty bus controller-which also caused errors in sound, but also did not report any error anywhere.
|
| 20. | However, this inter-message gap can be, and often is, much larger than 4 ?s, even up to 1 ms with some older Bus Controllers.
