Hi Richard, the cable shipped with such units has been found to cause issues more than once, so I'd recommend to try first with a different (i.e. higher-quality) one.
If that doesn't help it might be worth the time to try and remove/ blacklist the kernel module xhci-hcd as it has been the reason for LIBUSB_ERROR_TIMEOUT issues in *my* case. Not sure what your system-level knowledge is, so just in case: you can use "lsusb --tree" to check if the device is attached to a root hub that is serviced by xhci-hcd. All the best, -Soeren On Thu, 2015-06-18 at 23:51 +0200, Richard Ulrich wrote: > Hi, > > today I received my first ever logic analyzer, and subsequently found > and installed sigrok and pulseview from the ubuntu repository. > The software looks very good, but unfortunately, there is a problem > connecting to my device.
