Note that other user-level applications require write access to the raw USB devices. One example is "fxload", which is a firmware loader for Cypress FX2 EZ-USB interface chips. These are very common on FPGA development boards.
I worked around this as above, by assigning the plugdev group to the files via udev, but clearly a better solution is needed as the original kvm bug points out that the "groups-as-permission-domains" model is going away (a dumb idea IMHO -- replacing one access control model that's worked well for decades with a dozen mutually-incompatible domain-specific ones seems awfully overcomplicated to me...). -- Non-root guest doesn't have permission to access sys-fs USB devices https://bugs.launchpad.net/bugs/331331 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
