hid transfer of more than 255 bytes
« on: March 05, 2014, 08:34:21 pm »
Hello,
I need to implement HID device which is capable of transferring 400 byte of data in IN and OUT reports over interrupt endpoint in USB 2.0.
I can set needed maximum packet size in endpoint descriptors, but the report count in a Report Descriptor is only 1 byte, so the maximum report length I can get is 255.
How do I solve this problem ?

Thanks a lot
