FFHWA-2 This is unknown to me, looking at a company called Mercury Systems show they are involved with cell processors, could be this is some sort of ASIC, in which case it might implement a known protocol. > There is also a chip with pins on two edges, which is nearer to the usb-port > and labled with: > ? ? tm ? ?(superscript) TE ? ?

Still , if not, maybe now you could get a USBsnoop under windows (simply lowest resolution, small area maybe 1 inch by 1 inch, all automatic settings turned off)? Best regards, Gernot Hassenpflug
