Hi, You should compare things like CPU usage and number of interrupts during data transfer, before we could say anything for sure. BTW: Maximum block size for USB 2.0 under FreeBSD is 64Kbytes. BTW: You could try to make a simple c-test program that reads and writes random LBA's from user-space, and see when it stops working. --HPS _______________________________________________ freebsd-usb@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
