No need to worry about this. The "mmc" driver handles both MMC and SD
cards (their protocols are almost identical). The "sd" driver
actually stands for "SCSI disk"; but in recent kernels, SATA and USB
storage media also show up as "sd" devices.
So if you access your SD card via a USB adapter, it becomes an "sd"
device. If you access your SD card via a builtin non-USB SD
interface, it becomes an "mmcblk" device.
Ah! The issue is probably that he's accessing "mmcblk0p1", that is,
the first partition. I thought the USRP2 used unpartitioned cards,
i.e. he should write to "mmcblk0" (which will overwrite the partition
label and eliminate those p1 devices on subsequent accesses anyway).
