[U-Boot-Users] Usbtty with Windows problem

Hello ,

I work with OMAP310 based board and I need to get u-boot usbtty console work with Windows. In linux it works fine, but with windows driver (usbser.sys) it hangs when sending from u-boot to host big amount of data, greater than USBTTY_BUFFER_SIZE. When reconnecting again - the rest of data is recieved. Do anybody know where to start ? Usbmon shows that after USBTTY_BUFFER_SIZE data is received to host all the rest usb packets are empty. So console hangs even when typing HELP command in it. I tried to make uboot look like ACM modem, (added acm class desctiptors to USB configuration) but it didn`t help.
