Composite USB on win 10

[raluralu]

We have difficulties making working composite usb device. Available source example  dev_composite_cdc_msc_freertos works for Linux (debian 11 on kernel 5.10), but we can not make this device working on Windows 10. Windows reports that it can configure, but not start device. Result is that example device can not be used on Windows. USB sniffing provides some help,  but we can still not find exact source of a problem.

SDK: 2.10 (2021-07-15)
Manifest: 3.8.0
Devboard: OM13098 - LPCXpresso54628
Example: dev_composite_cdc_msc_freertos
Usb port - Fs  (source is generated for this port by default)

Any pointers that can help us move forward will help, Kind regards, Luka

So far we found out that issue seems to be because all class handlers receive particular class event. Function "USB_DeviceClassEvent" dispatch request for particular class to all class handlers not only to handlers/classes this request is for.
