Description
Hello VB,
After having used 4.X with great pleasure for a long time to debug Windows USB issues in Linux (Fedora), i have hit a snag in the 5.X series.
The problem is always the same. If i start streaming ISO packets they get stuck after a very short while. In the early 5.X builds the entire VM would implode, but now it just hangs the USB stream until i unplug the device. There is some kind of bug in the 5.X USB implementation. If its the VB drivers in Linux or the virtual drivers in Windows is not clear to me.
Has anyone else seen this problem? I have tried all combinations of options i could think of but the problem persists.
I have attached a Wireshark trace that shows the problem up until the hang. Note that when this happens the *entire* USB freezes up, not just the ISO packets.
Thanks,
/pedro

If this is still an issue you might try the latest 5.2 or 5.1 testbuild from the Testbuilds page, we identified and fixed an issue in the OHCI and EHCI controller emulations which could explain your issue. If still an issue please upload a VBox.log of the affected VM.
