[c-nsp] USB Serial adapter and ASA 5510

[Jay Nakamura]

This is just a curiosity question, I have a pretty generic USB serial
adapter (CPTech CP-US-03)  to console into network gear.  For some reason, I
can console into anything except ASA 5510.  When connected to ASA 5510, the
output is mangled like the console serial parameter is off.  But it works
fine with the same setting on an older laptop with builtin serial port.  I
have used this USB adapter for ASA5505, ISRs, 7500, Dell switches, Netgear,
Adtran, HP, damn near any other gear and it works perfectly.  I have couple
of the same model adapter and they all do the same thing only on ASA5510.
 (Haven't had the opportunity to touch a bigger ASA)

Anyone else run into something like this?
