Hi,
got this code for a dacal dc300, its a cd library,more info on
http://www.dacal.com.tw. But now I want to convert it to a kernel
module, but the first thing I don't know how I would use the function
usb_control_msg(). I need it to fill with the data I retrieve from
usbsnoop.log that is included and can be found in dacal.tar.gz
Also can i find something where the current cd is, like in position 57,
the dacal keeps track of it because the number keeps displayed on the
led, so I should somehow have to access the led?
dacaldcxxx.tar.gz is the code for the kernel module it doe nothing but
load into to the kernel reistering the device the dacal.TAR.GZ uses
libusb to use the device ut it only runs under root otherwise the device
does nothing, why is that???
Why not just stick with the libusb version? And if you use the latest
version of libusb, it will use the /dev/usb/ nodes found on the latest
2.6 kernel versions which makes it easier to set the proper user
permissions. That will help you out from having to run the program as
root.
Ok if I stick with libusb I still have the problem with the permisions
and I don't know what to change(newbie here)
As a side note, your attachments made a whole lot of email servers puke
messages back to the list admins. It's not your fault at all, it's just
some companies (Intel in paticular) is really dumb in not allowing any
attachments to come through their system, so a lot of different people
on this mailing list never saw your original post :(
Sorry about that, in the future I will post a weblink.
thanks,

Is there a way to access the led on the device? Also it is possible to
attache more than one Dacal device but how would I know, a) how many of
the same devices are connected b) how would I get the right usb_device
pointer c) how would I write a callback so the app can know something
is changed like an new dacal device is connected or disconnected?
Thanks for the help
