It all depends on the device.
A C example here (sorry right now I have no pyusb example).

To use libusb
Thanks, but i am sadly confirming that this is not the error this time.
I have correctly detached it with:
interface = dev.get_interface_altsetting()
dev.detach_kernel_driver(interface.bInterfaceNumber)
which works, because "dmesg" logs it and the /dev/ttyUSB0 is released.
but in the error stag

For libusb-0.1

For lib

The point is, that running it as root i discard the usual questions,
"do you have the correct permissions?"
Yes, i have, and tripple checked

What do you
Hi people.
I am on the middle of an electronic project which handles USB throught
the device TUSB3410 which is a USB to serial converter.
The main problem of this device is the intense lack of documentation
and examples of how to program it.
Any way, researching a lot i found that the BSD project
The ctypes.util.find_library() function in Python 2.6.4 is currently
broken on MIPS platforms.
Which mostly affects OpenWrt users running Linux on MIPS based access points.
The attached patches include a quick fix around that problem for PyUSB 1.0.
