<br>
I want to be able to match devices, exported by the ipp-usb, with the <br>
underlying USB devices, because every second user asks "where is my <br>
newly connected USB printer?" and needs to be pointed to the list of the <br>
network printers.<br>
<br>
For this purpose I want to add a couple of parameters to the TXT record, <br>
published by the ipp-usb:<br>
<br>
usb_SER=VCF9192281 ; Device serial number<br>
usb_HWID=0482&069d ; Its vendor and device ID<br>
<br>
However, if there are already standard names defined for this purpose, <br>
I'd prefer to follow the standard. Please, point me to the right <br>
direction at this case.<br>
<br>
WDYT?<br>
<br>
