Hello. I develop driver for USB 2.0 camera. It has 2 IN endpoints with MaxPacketSize 512 bytes. I need to read stream of video data about 28 Mb/s. I use 4 urb in queue for each endpoint's stream. The main trouble is that if the amount of data which i need to read in one URB divide on 512 without any rest then data transfer works fine. But if a size of URB not divide on 512 without rest part i receive EOVERFLOW error. for example - size of URB was 1854 and in URB's callback function i see that urb->actual_length = 1536. Are there some ideas about this trouble ?
