bEndpointAddress
2
1
The address of the endpoint on the USB device
described by this descriptor. The addess is encoded
as
7: Direction (ignored for Control Endpoints)
0=Out Endpoint
1=In Endpoint
6..4: reserved (always 0)
3..0: Endpoint Number
10000001b
bmAttributes
3
1
This field describes the endpoint’s attributes when it
is configures using the bConfigurationValue
1..0: Transfer type
00=Control
01=Bulk
10=Isochronous
11=Interrupt
00000011b
wMaxPacketSize
4
2
Maximum packet size that this endpoint is capable of
sending or receiving when this configuration is
selected.
For interrupt endpoints, this value is used to reserve
the bus time in the schedule, required for the per fram
data payloads. Smaller data payloads may be sent,
but will terminate the transfer and thus require
intervention to restart.
0008h
bInterval
6
1
Interval for polling endpoint for data transfers
(expressed in milliseconds)
0Ah
