Hi all
I am goig to develop a driver that read and write data from anchor usb chip using bulk transfer.
but I have a question to ask:
am I free to send any buffer sizes larger than 64 byte and the usb lower drivre will handle the packetting issue.? and what is the maximum limit if there .!

This is dependend on your USB firmware. Use what you need and forget
the MS bulk sampe with staged IO.
When you have different packet size during your session, use the
USBD_SHORT_TRANSFER_OK flag. I use a bulk pipe for USB bluetooth
adapters and setup read with 1024 bytes for the ACL pipe.
