Problem when changing usbHidReportDescriptor

Post by Micha » Fri Jan 06, 2012 1:58 am

Hello,

i have a usbHidReportDescriptor that looks like the following and works, that means the device is recognized and initialized by WinXP.

Code: Select all

PROGMEM char usbHidReportDescriptor[USB_CFG_HID_REPORT_DESCRIPTOR_LENGTH] = {
    0x05, 0x01,                    // USAGE_PAGE (Generic Desktop)
    0x0b, 0x01, 0x00, 0x00, 0xff,  // USAGE (Vendor Defined Page 1:Vendor Usage 1)
    0xa1, 0x01,                    // COLLECTION (Application)
    0x15, 0x00,                    //   LOGICAL_MINIMUM (0)
    0x26, 0xff, 0x00,              //   LOGICAL_MAXIMUM (255)

#endif
    0xc0                           // END_COLLECTION
};

This works well as long as USE_IRSND_CAPABILITY is set to 0. As soon as it's set to 1 (regardless of the setting of USE_BOOTLOADER) it doesn't work any more. In the device manager I can see a yellow exclamation mark and when I click onto the device it tells me something about a code-10 error.

lss-output with USE_IRSND_CAPABILITY = 0 -> working

Code: Select all

00000149 <usbDescriptorHidReport>:

     1d9:   95 01 09 00 b2 02 01 c0 00                          .........

Does anyone have an idea what could cause this problem or have any experience with it?

Strangely the problem also appears when I remove a report ID (e.g. ID 0x32).

I did some more testing: meanwhile it seems to me that either the number of reports (report IDs) or the length of the desriptor is limited. When I remove one report I can set USE_IRSND_CAPABILITY to 1, so the last sentence in my last post it not true.

Can anyone imagine or confirm such a limitation?

Well, USB_CFG_HID_REPORT_DESCRIPTOR_LENGTH should not be larger then 255 I can say you that with a quick glance at the code. But I don't think you have crossed that limit. Other then that I don't know...

The lenght of the report descriptor changed. Maybe forgot to change the RD lenght in the configuration descriptor ?
