Anyone have experience using a USB-to-serial device on the Gumstix Overo? I’ve been beating my head trying to get one of these adapters to work (I’ve tried 2 FTDI devices and one Prolific device). I plug the adapter into a powered USB hub (I have a USB Ethernet adapter also plugged into this USB hub, and that works fine – so I don’t think the issue is with the USB hub). I installed the ftdi driver (kernel-module-ftdi-sio). However, in /dev, I don’t have a device like “ttyUSB0” show up when the USB-to-serial adapter is plugged in. When I boot the Overo, I see that the device is recognized:
usb 1-1.2: new full speed USB device using musb_hdrc and address 4
usb 1-1.2: configuration #1 chosen from 1 choice
usb 1-1.2: New USB device found, idVendor=0403, idProduct=6001
usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-1.2: Product: FT232R USB UART
usb 1-1.2: Manufacturer: FTDI
usb 1-1.2: SerialNumber: A70076KJ
And in /dev, I see some related devices:
crw-rw---- 1 root root 254, 12 Jan 1 2000 usbdev1.4_ep00
crw-rw---- 1 root root 254, 11 Jan 1 2000 usbdev1.4_ep02
crw-rw---- 1 root root 254, 10 Jan 1 2000 usbdev1.4_ep81
However, I can’t “cat” to any of these devices, and as I mentioned I don’t see any device like /dev/ttyUSB show up.
Any help is very much appreciated!
