omapl138 uvc摄像头使用问题

Other Parts Discussed in Thread: SYSBIOS, BIOSLINUXMCSDK

在omapl138evm板上跑mcsdk的linux3.3和sysbios,用720p的uvc摄像头接在usb1.1上可以正常采集图像,分辨率只识别160x120。接在usb2.0otg接口上能识别1280*720的分辨率,使用v4l2的应用接口,打开设置格式都正常,就是最后ioctl(VIDIOC_STREAMON)失败,报错uvcvideo:Failed to submit URB 0(-90),(-90)在内核错误中表示 message too long

在ti中文和英文论坛上看了好多人都遇到这种问题,但是没有人给出解决的方法,感觉是musb驱动的问题,请问这个应该怎么解决,是否有新的内核补丁
