Implementing 2 OUT pipes USB HID possible?

Sona m

Hello,

I have implemented one interrupt type IN pipe and 2 interrupt type OUT pipe 1byte size and 8byte size respectively.
I see data coming in on IN pipe successfully.But when i send data on OUT pipe I see no data.
If I remove the 8 byte OUT pipe I see data being handled faithfully.

So, I need to understand if implementing 2 OUT pipes (interrupt type) in same interface configuration is possible?

Regards,
Sonam.

    It is possible but in that case you have a vendor specific class and you have to write your own driver for Host also.

    But perhaps you can solve your problem with using 2 OUT reports on same endpoint instead of two different endpoints.

    You should read HID specification from usb.org
