Hello, I don't recognize the template of your subdataset:  perhaps you 
are referencing it incorrectly?

I don't have access to any HDF5 files, but one HDF4 file I have with 
several datasets like this:

 SUBDATASET_1_NAME=HDF4_SDS:UNKNOWN:"200201h18ea-gdm.hdf":0
 SUBDATASET_1_DESC=[2048x1024] Sea Surface Temperature (8-bit integer)
 SUBDATASET_2_NAME=HDF4_SDS:UNKNOWN:"200201h18ea-gdm.hdf":1
 SUBDATASET_2_DESC=[2048x1024] Number of Observations per Bin (8-bit 
integer)
 SUBDATASET_3_NAME=HDF4_GR:UNKNOWN:"200201h18ea-gdm.hdf":0
 SUBDATASET_3_DESC=[2048x1024x1] Raster Image #0 (8-bit unsigned character)
 SUBDATASET_4_NAME=HDF4_GR:UNKNOWN:"200201h18ea-gdm.hdf":1
 SUBDATASET_4_DESC=[2048x1024x1] Raster Image #1 (8-bit unsigned character)

I can access one of these by using

gdalinfo HDF4_GR:UNKNOWN:"200201h18ea-gdm.hdf":1

gdal_translate HDF4_GR:UNKNOWN:"200201h18ea-gdm.hdf":1 out.tif

Cheers, Mike.
