Looks like your driver's configuration descriptor isn't being
delivered as you expect. For example, the wTotalLength of what
Linux sees is 0x0019 not 0x0029, iConfiguration is zero not 2,
bmAttributes and bMaxPower values are different, and so on.
Your driver is probably passing some other descriptor instead
of this one, or mangling it while during transmit.
0x09, // length of configuration part only!
0x02,
// L_F_CONFIG is length of entire config descriptor
0x29,
0x00,
0x01, // One Interface
0x01, // bConfiguration Value
0x02, // String Index
128, // bmAttributes
25, // MaxPower *= 2 mA
// Interface Descriptor
0x09, // #10 bLength
0x04,
0x00, // Interface # 0
0x00, // Alternate setting 0
0x02, // bNumEndpoints this is changed to 0x01 in
//dmesg debug ???
0x03, // bInterfaceClass
0x00,
0x00,
0x00,
// this is not showing in dmesg at all !!!?
0x09, // HID descriptor
0x21,
0x10, 0x01,
0x00,
0x01,
0x22,
0x3d,
0x00, // #16=0x01->boot
// Endpoint 1
0x07, // #28 bLength
0x05,
129, // bEndpointAddress
0x03, // bmAttributes -> interrupt
64, 0x00, // wMaxPacketSize
0x08, // bInterval
// Endpoint 2
0x07, // #28 bLength
0x05,
2, // bEndpointAddress
3, // bmAttributes -> interrupt
8, 0x00, // wMaxPacketSize
8 // bInterval
}
