Yamaha RP U100-- How do I get this device going?
Posts: 793
USB Gurus, please help.
I have been dealign with this problem ever since I started with mepis and all Linux distros.
I have Yamaha RP U 100 receiver designed to be used with a desktop PC. It has software control programs for Windows to do things like turn the Yam on and off, adjust volume... many functions.
The unit works fro audio playback like any receiver with the soundcard out attached to the PC jacks in. it also works to get audio from it's tuner and aux inputs out to the card for recording/ripping to a file. these functions work under it's Windows software.
As I move to linux I'd like to know how I can get the Yam to, for instance, just turn on and off. With all the midi and synth software available via Alsa and such, I'm thinking that there should be some standard USB protocols to send a command from linux to the device via its USB connection.
At bootup, Yamaha USB devices are found but Unknown. I can print out the kudzu if that will help.
Also sourceforege might have something on this, but I don't know how to navigate all it's options and such.
I've asked these questions numerous times in a lot of forums but no replies ever come. I even contacted some Yamaha honcho and he didn't give back anything either.
kudzu -p etc

I ran a kudzu -p and it gave some detail
on the Yamaha as an input device as I recall
but there were several USB items found that were
unknown.
I have no idea how USB commands are written as code
to control on-off through software, but Yamaha was
able to do it. I figured that USB code has to be written
in some sort of standard fashion.
The kmix issues are well-known to me. The Yamaha is a gadget
in the classic sense I suppose. It got closed out (I believe)
because the front panel is real confusing even with the
manual open. Software works pretty good though and it works
where the front panel doesn't to do certain things exclusively.
I've not been able to locate any Yamaha programmers nor
do I know how to get at the code.
I'll try to cut and paste the relevant stuff from the kudzu...
You will be interested to see this: I copied what follows
by hand from a Live CD and include all my hardware. I tried
to be carefull to do it accurately but in these text boxes it may come up all screwy:

USB in the kernel
Posts: 793
I've been poking around USB tutorials and some
commands to access the kernel to turn on USB in
sound and then turn on something in sound as well.
The commands make menuconfig
make xconfig
just produce target errors.
How do I get access to USB in the kernel?
My /usr/src/ contains:
/usr/src/linux-2.6.10-patches/
a similar item for 2.4 kernel and some
other stuff that won't cut and paste.
So how to make menuconfig for this?
I am trying to get hold of audio tools for this.
Audio tools like volume control have been unavailable or
uninstalled or device not found etc etc.
sound does play through system notifications, RealPlayer,
and xmms. Just no software control of audio.
kmix, aumix, any of that either produces errors or is
not found at all.
kernel-source?

have you got the kernel-source installed?This can be changed. Does anyone know if there was a good reason the
GPCG lists were set as reply-to-author?

One of my questions was how to access the kernel
thingies which is supposed to display like
rows of buttons you can click on and open--
I guess.
Kernel source is yet another new term for me.
Are you getting mail from me?
Sorry if that's the case.
As to kernels, I only have a couple pages of
book info on it and the make xconfig routine
was not working for me. I have located the
directory where the kernel images (?) are stored.
I can provide more info in the AM.

look what got pasted in the post....
something out of an email I read
you have to install kernel-source for the type of kernel you have eg 2.6.10 and for the machine eg 686
best to search in synaptic for the one you need
didn't see any mail but...

I still don't know what the mail problem is
but today I saw something interesting on the agnula demudi
list about kernel stuff.
I'm thinking that I should be in an i386 kernel for this
setup because it's pretty old. The kernel issue mentioned
was as follows:
So if I have an i386 kernel image with the latest
multimedia tweaks, this should be what I need to
do whatever development of multimedia I want to do.
Explain what is needed to be installed as source etc?
Even so we seem to getting far afield from the
sound problem, but maybe not. I'm still not knowing
how to access even looking at the kernel modules.
Those 'patch kernels' in the usr/src/ directory...
is that a place to start?
The guy at the agnula list said this:

Is this a tweak I could use?
I don't even know if Debian works today.

Hi Lon,
You get 'props' for doing your homework. Your Yamaha device looks to be sort of nifty so I dug around. What did I find, you might ask? Well, about 17 different web sites with the same question posted by some loninappleton dude.
Other stuffis: This device is 'old' by todays technology standards and somewhat obscure. It uses USB 1.1. It is compatible with Mac. It does not work well on XP (?). Saw one mention of device working on Ubuntu (Hoary) but had issues with kmixer. So it sounds like it will work but with limitations.
Does the yamaha show up as a device in Konqueror? Can you mount it?
