Keyspan USA-28

[William R Vogel]

I thought I was ready to upgrade my Xtension systems (Primary & Backup) to newer Mac Minis, as my current ones top out at El Capitan and I want to be ready for future updates.

I could not get the XTB-232 to connect and Xtension complained that the Keyspan USA-28 was not found. I poked around and tried various things, including looking back at the archive for this list. It appears that Big Sur no longer supports the old drivers and I could not find new ones.

Swapped everything back to old system and I’m back on the air.

Is there a new driver for the Keyspan, or should I purchase FTDI based adaptors?

Thanks, Bill
