driver station firmware update

[bobbyt14]

Our team is having trouble uploading the firmware onto the Driver Station.

It seems that other teams have also had trouble, probably because of the wrong type of USB drive, but our problem is a little different.

The docs from FIRST say that we should use a usb drive that should not have auto-run programs on it... it would help if someone could clarify what that really means, because we have tried several different drives, some old, some new (from 128mb to 8gb). If the drive is the problem for us, then FIRST has done a poor job selecting hardware, since it's firmware updates would be incompatible with most drives. I do not think that's the problem though.

the file size we tried to load was about 2.2mb (it would have helped for first to clarify that rather than just say in the troubleshooting section to make sure it was the right size)... and the name we tried was dsud_pkg.bin, and that exactly. Different variations of capital letters were also tried, but I'm guessing that is not our problem either.

with the drive inserted (and no other devices connected to the DS) we plug the power cable into the DS and wait for it to load, then wait for the USB drive's activity light to flicker (indicating that it has at least been accessed once). we then press the left (up arrow) and center (down arrow) buttons at the same time and hold them for at least 7 seconds...

Nothing changes. The DS does not recognize the command to enter firmware update.

we have no clue what is wrong here. could the DS possibly be defective?
