[Ifp-driver-common] Changing from UMS Firmware on a iriver 799

[Thomas M. H. <tmh...@gm...>]

I got a iriver 799 and used the ifp tool to update it to UMS firmware.

The firmware is beta. One thing I've noticed is that uploading to it
is incredibly slow. I'd like to test this out with the old firmware to
see if there's a difference.

How can I access ifp now that I have ums on? Every time I try an IFP
command I get a "device not found" error. I'm a bit worried about the
prospect of being stuck with beta firmware forever -- any pointers
would be greatly appreciated :)
