Hi-  I recently purchased one of these on ebay and setup today following your great guide. However I constantly get the error message

"MLD 0: ASIC has stopped hashing, attempting to restart"

this has been going on for several hours now, 10 or 20 lines of the above, and occasionally  "Stratum from pool 0 detected new block"

i have googled and read for hours but i cant find this anywhere? could the stick i have purchased be faulty or am i doing something daft?

Thanks
