hi ainvinay

as much i know EHCI is the host controller which support usb 2.0 high speed transfer
and i am confused whether usb 2.0 support burst transfer.So can u make your question clear Plz.
As much i know Burst transfer supported in USB 3.0 and the controller supporting that is XHCI.

Hi,

yes i found answer..its not feature of usb2...it support 3.0...and you can specify it in enpoint context in xCHI.

soumyajit did you work of xCHI before? i am working on both ehci and xchi.

so may be that will be helpful if you wont mind to share your experience.

Best regards,
vinay
