Good morning.
I'm successfully talking with a Delta (www.delta.com.tw) PLC DVP-12SE with the
generic USB driver.
The vendor id is 0x05dd and product id is 0x0001.
It seems to me that windows uses their generic driver usbser.sys also (there is
only an inf file referring it and no binaries in the supplied driver)
usbserial: USB Serial support registered for generic
usbserial_generic 4-1:1.0: Generic device with no bulk out, not allowed.
usbserial_generic: probe of 4-1:1.0 failed with error -5
usbserial_generic 4-1:1.1: The "generic" usb-serial driver is only for testing and one-off prototypes.
usbserial_generic 4-1:1.1: Tell linux-usb@xxxxxxxxxxxxxxx to add your device to a proper driver.
usbserial_generic 4-1:1.1: generic converter detected
usb 4-1: generic converter now attached to ttyUSB0
