Hello, I'm having trouble using a second Keyspan USA49W USB->serial port box. The problem is, the first one works flawlessly (we've been using it for months) and the second one is seen by the driver and initialized OK (or so it seems). The kernel sees it and assigns its ports to ttyUSB04 - ttyUSB07. I created device files to match up to these new ports and can even verify that the device is visible through them.
For instance, 'echo > /dev/ttyUSB04' exits cleanly when the second box is plugged in, but returns 'No such device' if you do it with the second box unplugged. Trying to access one of the ports in minicom causes it (minicom) to just hang. The related dmesg output is below. I saw an earlier post from 2001 where someone was having this same problem but no indication he got it resolved. Any help would be appreciated.
