sxccd.dec2image is quite slow

[clkotnik]

I found the byte swap in in dec2image to take a very long time. You might consider this implementation:
def dec2image( data, h, w ):
dt = np.dtype('uint16')
dt = dt.newbyteorder('<')
img = np.frombuffer(data, dtype=dt)

img = np.reshape( img, (h, w) )
return img

Hello, I am new to using cameras from the starlight xpress company. I used to use a program written in python that uses a 32bit driver, but decided to try direct communication with the camera, as you did. Despite the fact that I see the device in the manager, I enter the correct VID and PID, the program returns an error. Do you know what it might be about?

raise USBError(_strerror(ret), ret, _libusb_errno[ret])
