asking around on this issue, and haven't been able to resolve it yet.=20
I'm using FreeBSD 6.0 RELEASE with the GENERIC kernel. (from what i
can tell, it has all of the necessary pieces to allow usb drives).
When I plug my ipod into my computer, dmesg gets the following addition:
umass0: Apple iPod mini, rev 2.00/0.01, addr 2
However, that's all that appears there relative to it. From google, I
found that plugging in an ipod or a usb thumb drive should add a
/dev/da0 (or similar) entry to /dev, which you should mount. I still
don't have a /dev/da*, and I actually checked, and nothing is getting
added to /dev when I plug the ipod in.
Unfortunately a number of Apple iPod devices don't work with 6.0
release. FreeBSD sends a command to the device that causes the iPod
USB interface to get confused and it stops responding. This was
fixed in 6-stable, so you'll need to upgrade or patch the kernel
to get it to work.
You could also just manually remove the offending code. The change
you need to make is in /usr/src/sys/dev/usb/usb_subr.c. Find the
usbd_setup_pipe() function, and then put a '#if 0' and '#endif'
around the code for clearing stall conditions, i.e.:
#if 0
/* Clear any stall and make sure DATA0 toggle will be used next. */
if (UE_GET_ADDR(ep->edesc->bEndpointAddress) != USB_CONTROL_ENDPOINT) {
err = usbd_clear_endpoint_stall(p);
...
return (err);
}
}
#endif
Then recompile and install the kernel, reboot, and the iPod should work.
Ian
