libusb-1.0 通用制燃烧装置的书写权
原标题:libusb-1.0 write rights for generic usb device

I m programming in C with Anjuta a small application with libusb library.

libusb has need the write rights for some purpose. This argoment was already dealt in this topic: "Get access to USB device on Linux (libusb-1.0)?".
Maybe the topic solution work fine (I m not tried yet) but i would like my application access to all usb device and not to the specific one.
i ve tried to set a suid bit at a libusb-1.0.so file which have a root owner but libusbopen function, for example, answer "libusb requires write access to USB device nodes" again. I don t wont to build the entire anjuta project as root user but so far this is the only solution for this libusb-1.0 issue.

是否有办法在不修改ud夫行为的情况下书写使用一般灭火器装置(例如热pl包悬))?

问题回答

I have found a workaround. Maybe it s not good but it seems to work well. I have added a permission rules file (020_permissions.rules) in the udev configuration directory (/etc/udev/rules.d) where the unique rule is which Unix group should own all the USB device nodes.

The file content is:

SUBSYSTEM=="usb", GROUP=="group to belong my user"

我希望,如果你有类似的利弊问题,会帮助你。
