## Questions & Answers

**Q: Does it have working Linux drivers? I bought this and the linux driver is not compiling.**
A: Looks like it's using a v4l backport.  Your kernel is probably too new.  I got it to compile doing this.

 Create a file called 'config-mycompat.h' in media_build/v4l directory that contains:

#undef NEED_PRANDOM_U32_MAX
#undef NEED_PRANDOM_U32
#undef NEED_NEXT_PSEUDO_RANDOM32

Then the make should work.  A make distclean will wipe out this change, so you'll have to redo it.  I don't think there's any dev work going on for this product, so it is what it is.

**Q: will this work on Windows 11?**
A: Yes, that's what I am using.

**Q: will it work with a chromebook**
A: As long as your Chromebook has a standard USB input, it should work like any other Laptop.

**Q: Does it have signal strength meter?**
A: The A681B version I received has a signal strength meter
