I repasserais edit the message after test ... more
Otherwise the x52 is really beautiful, I look forward to successfully make it work - "

Well finally I managed to make it work, the format has not changed, and I resigned myself not to use the Saitek driver. Noted that it is still impossible to connect the PC directly to the beast, I must go through a HUB USB 2.0 ...
If the first test ELITE: DANGEROUS are very conclusive. I still recommend the product but only to those who have time to lose ^^.
