I cloned Debian's git packaging repository for garmin-plugin and had a
look at what it might take to get things fixed. Thing is, I cannot find
any code dependency on libusb. That is, there is no code that calls any
USB API. Unless code is pulled in during the build, the only thing that
"requires" libusb is the check at configure time.
The README documents a rather cumbersome build procedure that involves
compiling garmintools as well. I can imagine that that needs libusb.
Maybe that inspired the documented "need" for a libusb dependency?
As the debian/rules file simply builds below src/ without any of the
hoopla from the README, I thought you can just drop the libusb check
from the configure script and be done with it.
Tried that and quickly found out that the garmin.h header file from
garmin-forerunner-tools includes usb.h. The only other package that
depends on garmin-forerunner-tools is libgarmin-dev. Checked that
package's source and, unsurprisingly, their is zero mention of usb.
Moreover, it does not need garmin.h.
That means that splitting the USB stuff out of garmin.h would make it
possible to drop the libusb dependency on garmin-plugin.
However, that's more work than I'm willing to put in (now).
Hope this helps anyway,
