Just a side note before becoming excited about USB:
AFAIK (but I could be wrong), USB has no real interrupts
but always works in some sort of 'polled' mode. There could
be latency issues with USB devices if you need really fast response.

Kevin,

At SLAC, one of the RF physicists started using USB. To keep matters simple, he developed subroutines with which he could write to and read from USB. We then hook these in with subroutine records when time comes to put EPICS on it.

I'd also like to see some real USB driver-supported stuff.

Is anyone using the USB interface with EPICS? Of particular interest is the ThorLabs APT series.


Thanks,
