Dear all,
I'm starting with the Dreamplug and also with Linux environment.
Actually I've a DreamPlug with preinstalled Debian Lenny with kernel 2.6.33.6 and I like to start with some USB application because my goal will be control external device trough the USB bus.
As s first step I like to run a simple usb discover application. Regarding this point I've did a little search on the DreamPlug in order to understand what version of the libusb was installed:

dreamplug-debian:~# find / | grep libusb
/usr/share/doc/libusb-0.1-4
/usr/share/doc/libusb-0.1-4/README.Debian
/usr/share/doc/libusb-0.1-4/changelog.gz
/usr/share/doc/libusb-0.1-4/changelog.Debian.gz
/usr/share/doc/libusb-0.1-4/copyright
/usr/lib/libusb-0.1.so.4
/var/lib/dpkg/info/libusb-0.1-4.md5sums
/var/lib/dpkg/info/libusb-0.1-4.postinst
/var/lib/dpkg/info/libusb-0.1-4.list
/var/lib/dpkg/info/libusb-0.1-4.postrm
/var/lib/dpkg/info/libusb-0.1-4.shlibs
/lib/libusb-0.1.so.4
/lib/libusb-0.1.so.4.4.4
find: File system loop detected; `/media/usb1' is part of the same file system loop as `/'.

regarding this point I think that the only version is the libusb-0.1.
Now I like to ask to some expert following questions:

#1
I've read out here that there is also the libusb-1.0 version, is better to use this one or I can stay with the pre installed version libusb-0.1?

#2
I'm not able to found any .h file to include into source file, from this post I've discovered that I need to install the dev version of the libusb.
By using the command:

apt-get install libusb-dev

I can install the dev version of the libusb-0.1 this is approx 14.7 MB in size.
I've to use this one or is better switch to the 1.0 release and then install this one?

From my little Linux knowledge I've used this command:

dreamplug-debian:~# apt-cache search libusb
