About USB client Transfer rate.

Processor: OMAP 3530

BSP version: TI_EVM_3530 - 6.13.00

Platform: EVM

 

USB OTG is enabled for high speed client operation. We have mounted a RAM drive with the size of 20 Mbytes. This ram drive is exposed as a mass storage device to host PC by enabling Mass storage class client driver. While copying the files to mass storage, we noticed that, data transfer rate is 4.4 Mbytes per sec (Approx.).

 

As we are going to develop a UVC client driver, 4.4 Mbytes per sec of transfer rate is not enough, it is required minimum of 17 Mbytes/sec, so how can we improve the transfer rate to achieve 17 Mbytes/sec, do we need a changes in the USB OTG PDD driver available in the BSP?

Thanks
