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.

Best regards,
 Vovan                          mailto:vovan888 at gmail.com
