That sounds more-or-less like what I'm seeing now with my USA19,
currently connected with a Palm serial cradle. There were some other
issues as well, but so far I haven't been able to reproduce them under
the 2.4.6 kernel.
The interesting thing is that every now and then (not often,
unfortunately) the keyspan module will log an apparent error uploading
the firmware... after which it works *perfectly*! The actual log
messages are:
usbserial.c: ezusb_set_reset_Re254f24d- 1 failed
keyspan.c: ezusb_writememory failed for Keyspanfirmware (-110 0000 e0b4518d 3)
usbserial.c: ezusb_set_reset_Re254f24d- 0 failed
It occasionally works when the error isn't logged, but much more slowly
and with frequent timeouts. I *really* wish I had an idea of how to
trigger this error!
