LinuxQuestions.org - [SOLVED] USB [pyrocket] Launcher

Greetings Programs!

I just received a USB Rocket Launcher as a gift today... However, I'm sure she didn't intend for me to have more fun setting it up than using it.

I have found something called pyrocket, but I'm having a hell of a time getting it to actually work.

After installation, it started fussing about dependencies so I managed to get most of them installed. One dependency, however, I can't get it to detect at all. It spits out this (concerning OpenCV):

Code:

Traceback (most recent call last):

  File "/usr/bin/pyrocket", line 17, in <module>

    from rocket_frontend import RocketWindow

  File "/usr/lib/python2.6/site-packages/rocket_frontend.py", line 11, in <module>

    from rocket_webcam import VideoWindow

  File "/usr/lib/python2.6/site-packages/rocket_webcam.py", line 2, in <module>

    from opencv import cv, highgui

ImportError: No module named opencv

Since this model does not have a webcam, and I do not own a joystick, I took it upon myself to comment out the lines in rocket_webcam.py and rocket_joystick.py that called for opencv. I then continued to install the rest of the dependencies it asked for.

With everything ready, I put on my battle gear and got ready for war... but all my fun halted abruptly with a Permission error:

Code:

Located blue Rocket Launcher device.

libusb couldn't open USB device /dev/bus/usb/002/004: Permission denied.

libusb requires write access to USB device nodes.

Fatal Python error: (pygame parachute) Segmentation Fault

Aborted

Well... if it's a permissions issue, then I know just the user that can help me out. The SuperUser! So I logged in as root and gave pyrocket another go.... resulting in:
A little window pops up and starts to load... and then...!

Code:

Located blue Rocket Launcher device.

  File "/usr/lib/python2.6/site-packages/rocket_backend.py", line 103, in acquire

    self.handle.setAltInterface(0)

usb.USBError: Invalid argument

POW! And here, I am lost. I'm not sure if I entirely understand the error... There's a deprecation warning, followed by some complaints about particular lines in some python files, but nothing of any significants as far as I can see.

Maybe another few sets of eyes can help me get this working... my four just don't seem to be enough.

Thank you =^^=
