Okay as someone suggested, it was possibly a timing issue.
So, then I thought whats on my bus... and I have a webcam capturing
images every second with the spca5xx driver.
After stopping the capture and removing the module, it works now!
Greatly appreciate the help.

Which kernel versions?
Which version of libusb, if that is used?
Argh, sorry:
linux-2.6.19
dev-libs/libusb-0.1.12
If you don't do that, does it really work?
Not any more, I removed user privileges and it still doesn't work,
however it worked prior to these changes, maybe just by chance?
How are these machines different?
They are *exactly* the same in hardware. Also, we have two of these
USRP devices, neither work on my machine, both work on the other machine.
Also lsusb for your device and full dmesg please.

From the dmesg log, it appears that the Python program is sending a
message to the device which causes it to crash. Are you certain that the
same programs are running on both machines and are sending the same
messages?
Suggestion: Use usbmon to see the data being sent (instructions in the
kernel source file Documentation/usb/usbmon.txt).
