Works very well with Chen's cocoaModem, uH Router and Don's MLDX.
Both Chen and Don have done an excellent job in writing native
support for all the microHAM interfaces.

Checks with MMTTY/MMVARI/MMSSTV consistently show zero error
unless you try to "share" the sound chip between two applications
with different sampling rates that are not integer multiples
(e.g., 11025 and 48000 Hz).

The USB interface and USB Sound Device are industry standard devices
for which drivers exist in most LINUX distributions. There are still
some issues in writing applications to the microprocessor controller
in DigiKeyer, microKEYER and microKEYER II (to be released the end
of this month). Chen's uH Router can probably be ported to LINUX
using the named pipes interface if there were a developer interested
in taking on the task.
