Without this, only one transfer will be 60 issued in each microframe, significantly reducing the number of 61 periodic low/fullspeed transfers possible. 62 63 If you have multiple periodic low/fullspeed devices connected to a 64 highspeed USB hub which is connected to a highspeed USB Host 65 Controller, and some of those devices will not work correctly 66 (possibly due to "ENOSPC" or "-28" errors), say Y. 67 68 If unsure, say N. 69 |
