USB-EHCI reset issue

Hi,

I am working on omap2 board using usb in EHCI mode.Initially we are working on kernel 2.6.37 version.Using this kernel we are change the boot args for usb.From usb-filesystem kernel mounted and no reset issue of usb while copying files.


Now we are using the sitara kernel version is 3.3.7 for same board with same boot args for usb.From usb-filesystem kernel mounted.But usb getting software reset itself while copying file.

can anyone suggest out of this issue

Thanks 7 Regards,

Pradeep Kumar.G
