18 Solaris DDI specific (Solaris DDI)
22 The device qualifier descriptor \fBusb_dev_qlf_descr_t\fR defines how fields of
23 a high speed device's device descriptor would look if that device is run at a
24 different speed. If a high-speed device is running currently at full/high
25 speed, fields of this descriptor reflect how device descriptor fields would
26 look if speed was changed to high/full. Please refer to section \fI9.6.2\fR of
27 the \fIUSB 2.0\fR specification. The \fIUSB 2.0\fR specification is available
31 A device descriptor contains the following fields:
35 uint8_t bLength Size of this descriptor.
37 uint8_t bDescriptorType Set to USB_DESCR_TYPE_DEV_QLF.
39 uint16_t bcdUSB USB specification release
40 number in binary coded decimal.
42 uint8_t bDeviceClass Device class code.
43 (See \fBusb_dev_descr(9s)\fR.)
45 uint8_t bDeviceSubClass Device subclass code.(See
46 USB 2.0 specification of
47 applicable device class for
50 uint8_t bDeviceProtocol Protocol code.(See
51 USB 2.0 specification of
52 applicable device class for
55 uint8_t bMaxPacketSize0 Maximum packet size of
