Some devices are way to sensitive to noise and sometimes even timing. What you see is very likely a transmission error because of hardware problems and not of software. I would say the device is just badly designed. You may even change the situation by adding an hub between. -- B.Walter http://www.bwct.de http://www.fizon.de [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] _______________________________________________ freebsd-usb@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "[EMAIL PROTECTED]"
