My guess is that it worked because you reformatted the USB key. Some USB keys come preformatted in a "superfloppy" format, without a partition table, and FAT32 directly on the drive.
These drives still work as expected in Windows and MacOS, but not in the version of QNX that BMW uses (and some flavours of Linux). When the USB key is reformatted, it gets a partition table, and everybody is happy.
It's a case of "almost everybody uses Windows anyhow, so why should we care?", and drives appearing as a whopping 32 kB bigger without the partition table.
My advice:
Always format a new drive before use, no matter whether it comes formatted.
