Here is my situation...
The tests on the serial port have been successful, as far as they
went. That is to say that the results are no different than other serial
(non-ACM) connections. Which is to say, not good. The IrDA module is an
unknown so I tried my Palm Pilot (TRGnet Pro) cradle for hotsinking. I can
talk to the port and the palm pilot using cu but pilot-xfer can't open the
port. Sounds like a modem signal problem there. I've also talked to
a smartcard and a modem and a GPS receiver. I'm still doing baud rate trials,
but I'm having problems with connecting and disconnecting from the serial
port. About every third time I connect, the entire system locks up and
my video display (a VooDoo 3500) does weird things (every 5 to 10 seconds
it flashes and looses sync and then recovers). This doesn't seem to be
anything related to the Belkin per se, but some problem in either the
USB in general or the USB serial in general. This is on Linux 2.4.5.
Most of my other serial devices (ACM USB modems) are OK as long as I don't
try to do too much with too many at one time. This seems to be worse if
I specify higher baud rates (115,200 dies pretty quick. 38,400 takes a
few hits. 9600 takes some effort).
Still putzing with it.
