What happened ?

Use/examples/device/video_capture

define CFG_TUD_VIDEO_STREAMING_EP_BUFSIZE has a value greater than 1880

The image cannot be transferred I just want the transmission speed to be faster Because transferring Yuy2 format is very slow Or should it be solved from somewhere else？

How to reproduce ?

define CFG_TUD_VIDEO_STREAMING_EP_BUFSIZE has a value greater than 1880

This is not a bug. Please find the https://github.com/hathach/tinyusb/pull/1118#issuecomment-1008635903

Current UVC implementation supports only Full Speed. So, CFG_TUD_VIDEO_STREAMING_EP_BUFSIZE is acceptable up to 1023 byte.
