Is there any USB2.0 data transfer chunk size limit?

Is there any USB2.0 data transfer chunk size limit? With one read() or write() at a time, can we increase the bulk data size over USB interface? For example, I want to transfer chunk of 1024 (1K) bytes data and if the device has limitations of only 64bytes, is there any way I can increase the packet size for read() and write() system call over USB?

No, I believe it is dependent on the cluster size of the drive. You can define that through formatting.
