bfgminer -S all ?
Hi, thanks again for your reply.
bfgminer -S all i get "The request is not supported"
trying just
bfgminer i get this;

try --scan all or --scan compac
your screenshot tells me that there seems to be another problem here.... if both cgminer and bfgminer have problems using your USB ports....
maybe a BIOS setting / driver update ?
