Hello,

is there any set of library to interface with a USB (serial) device?
It seems that asyn can interface with drvAsynSerialPortConfigure() to /dev/ttyUSB0 device files... How are those files generated? ( I have /dev/usbXX on my machine. Are those the same?)

With usb-net module, I can trick the linux OS to create ethernet interfaces which are indeed USB ports. I could therefore have asyn connect using drvEthernetPortConfigure() (??) as well.

What do you recommend?

PS: Is anyone streaming lots of data (video, adc, etc) over USB?
