Thank you! Looking forward to feedback from more experienced owfs-eyes.. :)
Scanning the USB bus for vid/pid should be no problem. However, the
DS9490R seems to use a special vid/pid, where the LinkUSB uses a generic
"any-kind-of-ftdi-based-adapter"-vid/pid. Unfortunately the dumped
strings doesn't seem to help much either:
My LinkUSB:
ugen4.2: <FT232R USB UART FTDI> at usbus4, cfg=0 md=HOST spd=FULL
(12Mbps) pwr=ON (90mA)
bLength = 0x0012
bDescriptorType = 0x0001
bcdUSB = 0x0200
bDeviceClass = 0x0000
bDeviceSubClass = 0x0000
bDeviceProtocol = 0x0000
bMaxPacketSize0 = 0x0008
idVendor = 0x0403
idProduct = 0x6001
bcdDevice = 0x0600
iManufacturer = 0x0001 <FTDI>
iProduct = 0x0002 <FT232R USB UART>
iSerialNumber = 0x0003 <A900fx3D>
bNumConfigurations = 0x0001
Compared to another RS232-dongle (identical fields omited):
ugen3.3: <USB FAST SERIAL ADAPTER FTDI> at usbus3, cfg=0 md=HOST
spd=FULL (12Mbps) pwr=ON (44mA)
bcdUSB = 0x0110
iProduct = 0x0002 <USB FAST SERIAL ADAPTER>
iSerialNumber = 0x0003 <FTCDDBSX>
Not so much to go on.. the iProduct string is different, but I bet the
chip is not exactly the same, and that any FT232R based design
identifies itself as "FT232R USB UART"..
