In my source code I initialize ep_qh and dtd with 64 bytesmax,

In my interrupt, I acknoledge the Interrupt, I read the 64 octets received and i initialise the dtd to read 64 bytes.

this work for the first packet but after i have no interrput to read the following packets.

Could you help me?

Hello,
I found my mistake. I do not initialize the ZLT bit of the associate EndPoint.

Thanks for your help.
