WinUSB Low Bandwidth
We are using sync. slave fifo (2 bit addr, 32bit width, dma buffer size 16kB, dma buffer count 4, endpoint burst length 1) design with FX3 (ES chip).
Cypress driver's bandwidth is approximately 300MB/s (IN endpoint), 250MB/s (OUT endpoint). But WinUSB driver's bandwidth is only ~120MB/s in either direction.
How can be increased the WinUSB bandwidth?
