BF527 USB bulk IN DMA mode 1 with double buffering disabled

I cannot seem to get a bulk endpoint sending to a host (IN) to operate with a maximum TX packet size 1024, ie double buffering turned off using DMA mode 1 (32K buffers). I can get the same code and set up to work, and work well with double buffering turned on, ie maximum TX packet size of 512. Does double buffering disabled work with DMA mode 1 and autoset etc ?
