Subject: Kernel oops when shutting down program using usb device
Date: Wed, 16 Jul 2008 17:26:13 -0400 [thread overview]
Message-ID: <487E6775.7070804@balister.org> (raw)
[-- Attachment #1: Type: text/plain, Size: 2753 bytes --]
The program streams data from the USRP (Universal Software Radio
Peripheral) and calculates a transfer rate. It looks like the test
completes and the program ooops as it is exiting.
Let me know if I can collect anything else. I am not much of a usb guy :(
