I'm amazed you even get that fast, the usbserial generic driver is known to be slow by design. Use the option driver, and you should get speeds as fast as your modem and carrier allows. So just don't do the modprobe by hand, and everything should "just work" in 2.6.28 thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
