◆ bEndpointAddress

db usb_endpoint_descr::bEndpointAddress

◆ bInterval

Lower 11 bits form maximum packet size, next two bits specify the number of additional transactions per microframe for high-speed periodic endpoints, other bits must be zero.

◆ bmAttributes

db usb_endpoint_descr::bmAttributes

Lower 4 bits form endpoint number, upper bit is 0 for OUT endpoints and 1 for IN endpoints, other bits must be zero
