Dear all,
I just subscribed to this list since I encountered an issue after
pulling the latest git commits.
> lib: use interface 0 altsetting 1 instead of interface 1 ...
> This makes osmo-fl2k work again with Linux 5.5.0-rc6 or later,
On my system (Debian stable, kernel 4.19) this change results in
"Error enabling IF 0 altsetting 1". Reverting to the
previous version (with Interface 1) solved the problem for me.
I will investigate a bit more whether it is related to kernel or
libusb versions. Or have I missed some other required configuration?
Best regards,

Hi all:
I'm trying to build the latest gr-osmosdr package from the gr3.8 branch, but I'm
seeing some unusual errors, and I'm not quite sure what the deal is.
I'll note the following:
- I had errors related to existing python2 packages, so I tried building with Python3.
I'd be less than surprised if someone says that this is the cause of the issues, but
personally, I'd like to roll with the Py3 products from now on, what with Py2 being EOL…
- OS is Arch.
My cmake command was:
```
cmake \
-DCMAKE_BUILD_TYPE=Release \
-DPYTHON_EXECUTABLE=$(which python3) \
-DPYTHON_INCLUDE_DIR=$(echo /usr/include/python3*) \
-DPYTHON_LIBRARY=$(echo /usr/lib/libpython3.*.so) \
-DENABLE_DOXYGEN=1 \
-DCMAKE_INSTALL_PREFIX=/usr ../
```
Output from cmake:
```
