The Book Port is a USB 1.1 device. This is very interesting! >>> jerry.neufeld@xxxxxxxxxx 10/05/04 10:28PM >>> Playing with hardware for as long as I have, I should have guessed, I = should have known. Cables. About cables. Well, some just break, some perform intermittently, others are inappropriate. Recently, I have joined the = group of users of BookPort whose computers no longer recognize the device as of the most recent version of the firmware. Only one of my six pc's saw the BookPort as it should. As it turned out, that one machine had its own u s = b cable, I having used another for the remaining five, a cable that has = worked flawlessly since I bought it. Well, it don't perform no good no more, or, = at least, not with the BookPort. When I moved to another cable, this one said to be appropriate for u s b2 devices, all computers saw the b p without trouble. I must apologize to the a p h people for having added to their headaches. I always change my cables, just in the wholly improbable event that they are the cause of a problem. Although I assume the BookPort to be a u s b1 device, the x p operating system does not identify them as such with my computers, all equipped with the new, faster u s b2 ports. Does anyone at a p h or on this list know if the u s b 1 versus 2 can be at issue here? The cable that has proved = faulty became so only as of implementation of the newest firmware, a tad coincidental in my view. Tomorrow, I will check the integrity of my seemingly faulty cable with a known u s b1 device working from a u s b1 port. Again, my apologies for having added to the headaches.
