Hi,
 I am trying to support a product on several servers.
All identical. And have run into a puzzleing
situation. 

On one particular station something peculiar is
happening, the rev of a usb product changes. Intially
it said 1.10/1.00 the entire time.  Now it starts with
that, and after booting, it is 2.00/1.00 (see dmesg). 
All of the other stations were and still are allways
2.00? If I move the usb product to the other stations
the issue goes with the device. 

%dmesg | grep rev
usb0: USB revision 1.0
uhub0: Intel UHCI root hub, class 9/0, rev 1.00/1.00,
addr 1
usb1: USB revision 1.0
uhub1: Intel UHCI root hub, class 9/0, rev 1.00/1.00,
addr 1
ugen0: vendor 0xXXX1 product 0xXXX1, rev 1.10/1.00,
addr 2
usb2: USB revision 2.0
uhub2: (0x8086) EHCI root hub, class 9/0, rev
2.00/1.00, addr 1
ugen1: vendor 0xXXX1 product 0xXXX1, rev 2.00/1.00,
addr 2
ugen0: vendor 0xXXX1 product 0xXXX1, rev 2.00/1.00,
addr 2


What does the rev # mean? and why does it change on
the vendor\product line?  
Thanks so Much!!
