LIBUSB_ERROR_IO

[kasbah]

Hey, just unpacked my shiny new DSLogic (looks great!) and compiled the software. The GUI freezes though when I run DSlogic and press the aquire (play) button. This is on 64-bit Ubuntu 12.04.4. You can get debs of my binaries (made with checkinstall) here: https://seacloud.cc/f/ad1149d592/

Here is what is printed to terminal:

Failed to submit transfer: LIBUSB_ERROR_IO seems to happen with high transfer rate, long transfers and/or many channel. Try with lower sample rate...

We have found the cause. This issue will be fixed in next version, which will be released recently.
