I've use otx to disassemble the kext.

059F is lacie usb id.
the instruction then jump to offset 6A if the comparaison is OK (cmpw $0x059f,%ax)
0x0000f989 = 0000f91d + 2 + 6A
in an old patch driver, the JE op 74 is replaced by unconditional short jump JMP op EB
So open an hex editor, find 663d9f05 2 times (32 and 64 bit exe) and replace the following 74 by EB.

Thanks a lot Toine44. I patched the PXHCD and my external HDD is recognized
