I am developing a usb perihperal with the goal of high data throughput on a freescla i.Mx6 (phyFlex). My current UDC driver is "fsl-usb2-udc" on kernel 3.0.35. I was recommended the chipidea driver introduced in kernel 3.5 since it would perform better. Currently I have speed issues when I use gadgetfs with bulk transfer (~15MB/s) and I was wondering if the UDC driver could really be such a bottleneck. Thanks for any input! -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
