Did you make sure to use the MBR partitioning scheme and e.g. the FAT32 filesystem? Note that the USB key needs to have a partition table with a single partition. The boot recovery files need to be on that partition. Another common mistake is not to have any partition table or partition which will mean that when the boot recovery script looks for that partition it won't be able to find it.
The firmware image has no extension. Their are arguments both ways. OS6 firmware images have an extension .img, but that extension is also used in other settings for disk image files, which the firmware image is not.

Yes, the sticks are formatted FAT32 with a single, active partition (99.9% of the sticks report to Windows as "Removable Media" and unlike "Fixed Disk" it only supports 1 partition. I did one more try with the stick which was booting plugged in one of the 2 USB ports in the back (instead of the front). This time I noticed on the lan card a green led blinking (did not see it before) and now Raidar reports still 6.10.4 but with the EEPROM corruption "To be filled by O.E.M" and serial NONE00000000"
