On the M705 I frequently get usb timeouts here if the device has not been active for a while. Retrying after 10 ms seems to reliably fix the timeout problem. We could have just added the 10 ms sleep directly but it does not seem to be neccesary on wired devices so I chose not to. Setting the ret value to a face positive number and looping would also work but we risk an endless loop. In the end I just went for a single retry as that fixed the problem for me.

libratbag
libratbag is a configuration library for gaming mice. It provides a generic way to access the various features exposed by these mice and abstracts away hardware-specific and kernel-specific quirks.
Architecture
libratbag has two main components, the front-end API and wrapper code, and the back-end HW-specific drivers:
+-----+ +-----+ +-----------+ +----------+ | app | -> | API | -> | hw-driver | -> | protocol | -> device +-----+ +-----+ +-----------+ +----------+
The API layer is HW agnostic. Depend on the HW, the protocol may be part of the driver implementation (e.g. etekcity) or a separate set of files (HID++). Where the protocol is separate, the whole known protocol should be implemented. The HW driver then only accesses the bits required for libratbag. This allows us to optionally export the protocol as separate library in the future, if other projects require it.
