hid4java uses this library and I believe this issues to be causing major stability problems downstream. Downstream bug report: https://github.com/qzind/tray/issues/137 Note the [crash log also mentions `hid_enumerate()`](https://gist.github.com/tresf/7fa2c32ecead94a8ddb8f0a33dfc427c#file-java-hid-crash-log-L116).

@todbot yes, I believe I am. I'm using it indirectly [through a third party](https://github.com/gary-rowe/hid4java), so I'll have to see if switching is an option. Thanks.

@todbot thanks kindly for this information! What's not immediately obvious is why the `libusb-1.0-0`, `libusb-1.0-0-dev` are left out... or more specifically... how to build without them. How does the build...

Unfortunately no. We (my project) simply cannot support this type of hardware on Linux using the `hidapi` library.

In response to my previous message... the Windows serial number with question marks is specific to certain hardware, such as Mettler Toledo weight scales. This doesn't occur for all HID...
