I got access to an ellisys usb explorer and dumped the whole transfer between usb stick and lx800. I started to look at the whole USB stuff this day and I hope we can get it working :) To view the dump you need this: http://www.ellisys.com/products/usbex200/download.php The dump can be found here: https://docs.google.com/open?id=0B_fznDimUHVuTkRfYkE5b0NtRzg greets --- Christian Gmeiner, MSc -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
