I need to correct information that I previously posted relating to the
pegasus driver and to apologize to Petro and Donald for bothering them
about an adapter that may have been perfectly functional all along.
Linksys sells the USB100TX with Windows 98 support only. When I received
it I wanted to confirm its functionality on the supported platform
before attempting to use it with Linux. The first adapter that I
received was not functional, and the support technician issued a RMA
when he learned that the link light never came on. The light on the
replacement adapter came on after the driver was installed.
The adapter failed with the first Linux driver that I tested, and I
falsely assumed that the fact that the link light stayed out was a
symptom of not operating. With later drivers I gave up when there were
error messages logged and the light failed to come on.
I finally saw the light (figuratively) when Petko pointed out to me that
messages such as "party FAIL ffff" and "(open)failed intr_urb -22" were
simply warnings. Subsequent testing showed that the adapter works with
both Petko's driver for the 2.4.0 kernel and Donald's driver with his
USB stack for the 2.2.x kernels. Commenting out the intr_urb references
makes no difference in performance and it avoids the "(open)failed
intr_urb -22"
message.
The behavior of the lights is strictly cosmetic and I have no complaints
about the fact that they behave differently in Linux than under Windows.
Throughput with the adapter is about 500 K bytes/s. This is about the
same as Donald reported. Perhaps someone will explain why the
performance is so far below that of a 100TX network card. At any rate,
the performance is
satisfactory for communications with my I-Opener, and I am grateful to
all those who have contributed to providing driver support with Linux.
