I have a Ubuntu 10.10 (x86) system which I use to test GNU Radio applications. I have successfully been using a USRP1 with a USB2.0 connection for some time now, yet at some point yesterday it appears to have stopped working.
lsusbI don't even see the device listed anymore. I tried multiple ports with no luck.
- A USB1.0 mouse seems to work fine.
- Windows XP seems to recognize the device (no driver, but I see the device ID)
- USRP works fine on my Fedora machine
- tried different cables and another USRP
This is a rather old laptop, so part of me thinks the hardware may just be dying. However, Windows still at least recognizes the USRP, so I am hopeing maybe a driver install will fix the problem.
So, a USB mouse works fine, but somehow my USB2.0 based USRP stopped working. How can I debug this problem? Can I somehow reinstall the USB2.0 drivers?
