Problems with Nokia PC suit (6101) and DKU-5 cable? - dku 5 pl2303

OK, I have the DKU-5, I, the PC Suite, which says all very well installed, but my phone is not "accepted" the cable that it is not compatible, ... Ideas? Everything works fine, my computer accepts the cable, but my phone (Nokia 6101).
Perhaps it is blocked? states that "certain that your phone is not locked for security reasons," how can I do that?

Thank you!
