I'm wondering if anyone has encountered this before and/or has advice:
My USB device is "having difficulty" when I attach the XPort shield to the arduino board. When I load a script (in this case the Botanicalls Twitter script) it works fine as long as the XPort shield is not attached, and I get a steady stream of data from the serial monitor in the arduino env.
When I attach the xport shield and restart the board, it cannot detect a serial port from terminal and I get this error in arduino:
Serial port '/dev/tty.usbserial-A6004oD9 not found. Did you select the right one from the Tools > Serial Port menu?
The reason this is happening, I suspect, is because in the console I'm getting these bugs:
Jul 12 22:51:20 semeiotica kernel: FTDIUSBSerialDriver: 0 4036001 start - ok
Jul 12 22:51:55 semeiotica kernel: USBF: 7282.463 [0x328d800] The IOUSBFamily is having trouble enumerating a USB device that has been plugged in. It will keep retrying. (Port 1 of hub @ location: 0x3d000000)
Jul 12 22:51:59 semeiotica kernel: USBF: 7286.303 [0x328d800] The IOUSBFamily was not able to enumerate a device.
...so for whatever reason the usb connection is disappearing when I hook up the shield.
here is what I am running:
arduino software v11
adafruit's eshield w/LTRX XPort
FTDI serial driver 2.29
Mac intel OSX 10.4.11
using the botanicals twitter pde v2.13 (not that it should matter)
seems to be a hardware issue even though I've been over the wiring many times...
