Hello!
We have got a problem with USB together with RTOS. Maybe someone can help us.
It is not clear if the problem is caused by Windows or our embedded device.
uC: LPC2368 (NXP) Windows XP (Servicepack 2)
Our Device is a HID-Composite Device which can be configured to represent at maximum 5 Devices (one or more keyboards and gamepads). We made some changes in the USB-Stack to provide USB-HID-Composite Devices. The enumaration of the device always runs without problems. But after a random time Windows stops to request In-Reports. All endpoint tasks are running and the data to send is valid. But there are no USB_EVT_IN events. Feature Reports and Out-Reports are working reliable even if In-Reports are not working anymore. Becauce of this I think the endpoint-tasks are working.
Did anyone ever have such or a similar behaviour of a USB-Device? Maybe we've got a timing problem on our device? What can be the reason for Windows to stop catching InReports?
Thank you, Regards Klaus
