Eric, 

In the beginning USB was some what flakey with App_rpt. 

Over the last several years USB it has become much more stable. 

Given the choice of hardware for stability, the Quad PCI radio card wins, but the quad PCI card is no longer manufactured or sold. This is because of the price point. Hams did not want to spend the money for the 4 port PCI Quad card, when they can buy an $8 dollar USB sound fob and modify it to work.   from my iPhone

So why does it seem that most everyone has gone this route against the above sage wisdom rather than using something more akin an e&m interface like the pci radio cards Jim designed and built or the interface boards that plugged into an fxs? Port and broke out e&m, providing keying by polarity reversal of the battery voltage. Both solutions work rock solid with no issues. Apparently usb not so much and apparently this is a long standing problem with usb. In thinking about this I’m also curious if the design files for the pci radio interface boards may be available as they’d likely be a good start for an update to a more current interface standard.
