Any reply would be greatly welcome. 73s all. USB is single master. You can't connect two masters (hosts) directly together. A-A cables are illegal in sense of the USB specs, they don't work and can even damage the systems. Thosese cables are mostly sold because in a early USB specification there was only A connectors and a early hardware designs used A connectors instead of B. I personally would avoid such hardware. There are other options to connects computers together via USB. - Use two USB-Ethernet adapters and X-link them together and do Ethernet. - Use two USB-serial adapters and X-link them together and do ppp, slip, xmomdem or whatever. - Use a special host to host adapter - those simulate an serial adapter at each host side. AFAIK those adapters are all limited to USB-1.1 speed, so the Ethernet way can be faster if both sides can do high speed. -- B.Walter BWCT http://www.bwct.de [EMAIL PROTECTED] [EMAIL PROTECTED] _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
