[PlanetCCRMA] Re: 2.6.7 ccrma kernel and usb / nvidia support

[Shayne O'Connor]

ok, well i'd decided to download the fedora core 1 ccrma distribution,
but discovered most of the iso's were corrupted (you might want to check
their integrity - though it's probly just my incompetence that let to
their corruption), so i was a bit defeated by that, and just decided to
stick with standard fedora core 2 2.6.5 kernel. but i kept the ccrma one
on there, just in case i got the guts to screw around with it again.

which i did ... and for some reason, the nvidia driver compiled against
the 2.6.7 kernel - booting into it, it showed the nvidia splash screen,
and instead of freezing, continued to boot! in disbelief, i plugged in
my zen touch to the usb, fired up gnomad2, and lo and behold, it was
detected, and could scan the songs on the player, and also transfer
songs to it!!! everything was working perfectly!!!!

then, for no reason at all, i one day booted into the ccrma kernel
(which was, by now the default) and ... it froze again, just after the
nvidia splash screen, where it says "Setting hostname". Grrrr. So I
reinstalled everything again, thinking "freakin 3D acceleration! who
needs it?!". i mean, it would be nice, but i don't really need it - so
that's not the issue, anymore really.

after reinstallation, i tried to connect my zen touch with gnomad2 -
once again, i got the "no jukeboxes found on usb bus". grrr. so i
thought "ah, well - at least i can boot into the 2.6.5 kernel and it
works". so i did that. but a bit later, i decided to try plugging it in
again - and it worked!!! god knows why ... 

... then nvidia updated their driver, and i thought "hmmm, maybe this
one won't freeze my computer" - but, of course, it did ... and after
uninstalling it  .... "NO JUKEBOXES FOUND ON USB BUS"!!!!!!!!!

       ***************************************

i'm happy with the 2.6.7 kernel and the audio applications i'm now able
to use with it - it's been a long struggle to get here.

i can do without 3d acceleration - i accept this now, and ain't even
going to bother, no matter how compatible the drivers get.

i CAN'T do without the usb access to my creative zen touch - obviously
it CAN work on the 2.6.7 kernel, but only in what (to me) seem totally
arbitrary conditions.

Fernando - i don't know how to get any other error message than the one
that gnomad2 gives "No jukeboxes found on USB bus" ... as they say "i'm
totally new to Linux" ... could you point me to the shell commands i'd
have to type to get diagnostic information of the sort that would help
to solve why 2.6.7 is not recognising my device? as i said before, if i
boot up the default 2.6.5 kernel - it detects the creative zen touch
perfectly ...

please help
