I added debug messages into ProcessStandardRequest()
printf("ProcessStandardRequest: %x %x %x %x %x %x %x %x %x %x %x\r\n",
SetupPacket.bmRequestType, SetupPacket.bRequest,
SetupPacket.wValue0, SetupPacket.wValue1,
SetupPacket.wIndex0, SetupPacket.wIndex1,
SetupPacket.wLength,
SetupPacket.extra[0], SetupPacket.extra[1],
SetupPacket.extra[2], SetupPacket.extra[3]
);
and result is following (on Windows OS):
Device powered
WaitForSetupStage
Bus reset
WaitForSetupStage
Bus reset
ProcessStandardRequest: 39 26 5c 6b 39 2d 3fdd 45 3d 8 82
Stall
WaitForSetupStage
WaitForSetupStage
Bus reset
ProcessStandardRequest: 39 26 5c 6b 39 2d 3fdd 45 3d 8 82
Stall
On Linux I got totally different ProcessStandardRequest:
Device powered
WaitForSetupStage
Bus reset
WaitForSetupStage
Bus reset
ProcessStandardRequest: 88 21 ff 1 b7 29 ffffb7ff 60 0 0 20
Default Std Request
Stall
WaitForSetupStage
WaitForSetupStage
WaitForSetupStage
Bus reset
ProcessStandardRequest: 88 21 ff 1 b7 29 ffffb7ff 60 0 0 20
Default Std Request
Stall
WaitForSetupStage
The strange thing is that on Linux the addres went from 2 to 6 but
"ProcessStandardRequest" message was always the same.
I got different messages in /var/log/messages:
Device descriptor read/64,error -71
Device not accepting address NUM, error -32
I feel like Ghost Buster - something strange...
It looks like there is some problem with setupPacket structure. Does anybody
have a clue what is going on ?
