All other devices > not known will fall under ugen. It does not mean it is useable. Actually, ugen is usable. It provides a "generic" usb interface, that doesn't look like anything but a usb port. To use it, an application *must* know that it is talking to some device plugged into a usb port, and can't treat it as a parallel device (as lpd does in talking to ulpt), a disk drive (which is what umass provides), etc. Coldsync claims to be such an application; the documentation specifically says to use /dev/ugen0. That it's failing in this way indicates there's a bug in the device driver (actually, crashing the system as a normal user is a bug, even if what you're trying shouldn't work). Fixing this problem probably requires kernel-level debugging. If someone with a USB-capable Palm device wants to start on that, instructions can be found at <URL: http://www.freebsd.org/handbook/kerneldebug.html >. If someone wants to give me a USB cradle for my Palm V, I'll look into it :-). <mike > On Sat, 6 Jan 2001, Philippe CASIDY wrote: > > > On Wed, 25 Oct 2000 17:38:03 +0100, Niall Smart wrote : > > > > > >Is anyone successfullying sync'ing their Visor using a USB > > >cradle?
