Hi Emmanuel,

I have only used USB/RS232 and USB/RS485 adapters. The P&P magic built into the

Linux kernel maps them automatically to /dev/ttyUSB* where they can be used with

asynDriver just like local serial devices.

For a custom USB device that is not automatically supported by Linux, I would

suggest to write a Linux kernel driver instead of an EPICS driver. Have a look

at http://www.linux-usb.org/

Hello again,

I am contemplating writing a low level linux driver to read a stream of
data coming for custom made device and on a USB2 port.
This data will be fed to linux and then to epics.

Is anyone of you using epics with USB devices?
Any pointers? Does asyn interface with usb ports readily?

Regards,
