Install 3.5.1, they told me. It's better, they said...
Finally got SSH working on OZ 3.3.5, so I decided to upgrade to 3.5.1. Got all the bits and pieces and flashed it. Indeed, it's much nicer-looking. But when I plugged into the cradle, I didn't get the familiar boo-beep from XP.
ifconfig on the Z didn't show any IP address, and ipconfig on XP didn't show the connection as being up. So I went to Network on the Z, saw that DHCP was on, and manually entered the IP info I was using successfully before (the standard .201 IP address, etc). Pulled out and back in the cradle. Nothing. Tried the "Start" button: "Starting interface failed". Rebooted the Z while in the cradle. Still nothing. Tried enabling the connection from the XP side. Nope.
I searched the forums, and found some messages advising to use "ifup usbd0". Tried that, and got a few lines of "No such device":
SIOCSIFADDR: No such device
SIOCSIFNETMASK: No such device
SIOCGIFFLAGS: No such device
route: SIOC[ADD|DEL]RT: No such device
Also saw mention of just "usb0", and tried that too:
ifup: Ignoring unknown interface usb0
So I must be missing something -- what do I do to get the USB network enabled again?
