Don, I have found the second fax file now in the source tree:
fax/ppd/HP-Fax2-hplip.ppd
The pseudo device ID is:
MFG:HP;MDL:Fax;DES:HP Fax 2;
I suggest to modify it to
MFG:HP;MDL:Fax 2;DES:HP Fax 2;
as otherwise MFG and MDL are identical and so a printer setup tool which starts checking already after finding only MFG and MDL can confuse the files.
So please change this device ID to the version which I suggested and modify the hpfax CUPS backend appropriately, so that it outputs the device ID according to the actually connected fax device type. Please post also an appropriate patch for HPLIP 2.8.2 here, as we are already after feature freeze and therefore we cannot replace the complete HPLIP package.
