Hashcat Exhausted when using rules

Hi all,

Im trying to use STDIN and STDOUT with rules to ensure full GPU performance, but hashcat runs through it all within 5 seconds and states exhausted with no key found. Also GPU's are never used.

Using it without the rule works fine.

My rule creation

Code:

/mp64.bin -o sfxU.rule -1 ?u '$?1$?1'

My command

Code:

/mp64.bin  ?u?u?u?u?u?u | ./cudaHashcat64.bin --hash-type=2500 -r rules/sfxU.rule /cracking/wireless/testhashcat.hccap
