the HSF driver does have a fully working suspend/resume functionality in
the driver. We are aware that it's not perfect, it's still an ongoing
project, when we find a flaw in the driver, we try to fix it. For all
drivers, no matter the operating system, suspend/resume requires a lot
of cooperation between the kernel and other devices on the system and a
single and simple failure somewhere will prevent the complete operation.
With the number of possible setups, both hardware and software, it is
simply impossible to test all possibilities.
Making everything open source is not guarantee that it will work better.
Even when using a vanilla kernel from http://www.kernel.org without any
additional 3rd party kernel modules (i.e. a 100% open sourced kernel and
drivers), it's rare that I can get suspend working on my machines
properly unfortunately. We do the same as the kernel developers, we are
always slowly improving the software in this regard.
Note that some of the suspend code which is close to the Linux kernel is
open sourced in the driver. For example, when a generic package of the
driver is installed, you can take a look at the
/usr/lib/hsfmodem/modules/cnxthw*_common.c files on your system for the
code related to that.
