- Modification history
- --------------------
- 01d,26jan00,rcb Redefine "bandwidth" field in URB_PIPE_CREATE as UINT32.
- 01c,29nov99,rcb Increase frame number fields to 32 bits in
- URB_CURRENT_FRAME_GET.
- 01b,07sep99,rcb Add support for management callbacks and set-bus-state API.
- 01a,20aug99,rcb First.
