Hi,

The device enumerates on XP and Linux, but not on Windows 7. USBlyzer shows 'URB Select Configuration failed'
I've deleted all regestry keys for the device in XP and re-enumerated it and there are no errors.

In W7, all the descriptors show in the USBlyzer properties window except the HID report descriptors. I can see that when URB Select Configuation 1 happens, there is a URBD_STATUS_INVAlID_PARAMETER error. Sorry about the formatting, but here are the descriptors as captured on XP when the device successfully enumerates:

Why won't W7 enumerate my composite device?

Is the 64-byte max a requirement for FS bulk endpoints too?
Is this information in the USB spec somewhere?

USB2.0 spec (usb_20.pdf, http://www.usb.org/developers/docs/usb_20_070113.zip )
5.7.3 Interrupt Transfer Packet Size Constraints
An endpoint for an interrupt pipe specifies the maximum size data payload that it will transmit or receive. The maximum allowable interrupt data payload size is 64 bytes or less for full-speed.

5.8.3 Bulk Transfer Packet Size Constraints
The USB defines the allowable maximum bulk data payload sizes to be only 8, 16, 32, or 64 bytes for full-speed endpoints

Anyway, HID doesn't accept bulk endpoint.

You have 255 bytes output report on the report descriptor.
It's OK. Such a large output report is split into four packets (64, 64, 64, 63) on the firmware, over 64-bytes wMaxPacketSize endpoint.
There is no need to change your PC application at all. PC host controller (hardware) chains split packets into single one by 255 bytes read-out request.

Just the firmware routine, which sends the output report, is fixed for this trouble. Don't worry so much

PS.
Ah, to get better response, set the bInterval of the interrupt OUT EP to 1 ms.

6bInterval120h32 ms    <--- 1 ms

Thanks, Tsuneo!

Ouch! That's going to create some headaches for us and our customers. Simply changing the ep type to bulk didn't work either, and then our interface software on the XP PCs couldn't com with the device.

Is the 64-byte max a requirement for FS bulk endpoints too?

Is this information in the USB spec somewhere?

The wMaxPacketSize of the interrupt OUT EP takes 255 bytes
It must be 64 bytes or less, for full-speed device.

Endpoint Descriptor 01 1 Out, Interrupt, 32 ms
OffsetFieldSizeValueDescription
0bLength107h
1bDescriptorType105hEndpoint
2bEndpointAddress101h1 Out
3bmAttributes103hInterrupt
1..0: Transfer Type......11 Interrupt
7..2: Reserved000000.. 
4wMaxPacketSize200FFh255 bytes   <---- 64 or less
6bInterval120h32 ms

The criteria of descriptor check at SelectConfiguration (Set_Configuration) gets stricter on Win7 than WinXP.
