I've recently purchased the USB BUB and JeeNode. They don't seem to be working - I get an
I put it together according to the online instructions, along with a USB BUB, which I assembled by simply soldering on the 6-pin header blocks and jumper (which I connected across the 5V pins using the supplied jumper connector). When I plug the USB BUB with the JeeNode attached into my computer, I didn't see it in the Arduino ports section, and I saw an error in my system log (on my Mac):
02/10/2010 15:10:31 kernel USBF: 4019.896 [0x7116500] The IOUSBFamily is having trouble enumerating a USB device that has been plugged in. It will keep retrying. (Port 1 of Hub at 0x4000000)
I DO see the 3 flashes on the USB BUB, and testing with a multimeter revealed that everything was connected solidly. Then, I noticed the solder jumper on the JeeNode, and that the board wasn't actually receiving any power. I soldered together the solder jumper (right next to the battery connector holes on the JeeNode) and tested all of the connections one-by-one, and still the same error! I have the newest FTDI serial drivers (FTDIUSBSerialDriver_v2_2_14.dmg) for 10.6.4 and my Arduinos work just fine.
I also notice that, despite what the USB BUB says, my multimeter reads 1.5V between the two battery terminals on the JeeNode when it is plugged into the USB BUB. Am I not supposed to power the JeeNode off the USB BUB?
After further investigation, I read 2.6V across the USB BUB's power and ground pins when conencted to the USB by itself (with the built-in LED flashing quickly and repeatedly), and only about 2V across the same power and ground when the JeeNode is connected.
Can you please tell me what I can try at this point? It would be good to have a simple USB BUB guide, because there are many options, and it isn't clear (to me, anyway) what voltage it should be running at (do I need to solder a jumper across the 3.3V pin and short the 5V pin, or does the JeeNode expect 5V?)
- Solder 6 pin FTDI headers and 3-pin jumper headers
- Install FTDI serial driver, if needed
- Plug in JeeNode, then plug into USB port (or can you plug it in first, THEN plug in JeeNode?)
That would be great for us JeeNewbies...
