Ok, this is my attempt at a definitive bug report for this problem. Since it's mysterious, I'm going to try and be as descriptive as possible. Thanks in advance for your patience and help.
I am on a second gen macbook, OSX, running the latest (as of a day or two ago) from the svn trunk
I imagine that to get this information, information had to be sent over the USRP to my computer, so both sending and receiving information over the USB is possible.
Here is the info from system profiler:
USRP Rev 4:
Product ID: 0x0002 Vendor ID: 0xfffe Version: 1.04 Speed: Up to 12 Mb/sec Manufacturer: Free Software Folks Location ID: 0x04100000
Current Available (mA): 500 Current Required (mA): Unknown (Device has not been configured)
This is a screenshot of what happens on running usrp_fftp.py
As you can see, everything loads properly, but then it doesn't capture any data. Very odd. Could this perhaps be a problem with the batch USB data transfer? IE for some reason, I can still send and receive data, but not in bulk?
(also, there is a wx related error that I've always gotten and has never effected it before, and doing some research seems not to matter, but if you think it would help to fix it, I'm all ears)
Obviously, if I run other stuff relying on the daughterboard, the same happens. I've talked to some people and they think that it could be static, but I don't know. What on the board could be whacked such that this is what does not work?
Is there any recourse for fixing USRP's, or am I at the western frontier of open source development? As always, your help is greatly appreciated.
