Cisco USB serial console compatiblity?

[Brian Buhrow <buhrow%nfbcal.org@localhost>]

	hello.  Does anyone know what USB serial chip the Cisco USB serial console is closest to
in our USB serial drivers list?  the vendor code for the device I'm talking about is: 0x05a6
and the product code is: 0x0009.  It doesn't look like we have a driver that recognizes these
codes, but I'm thinking it should be easy enough to add them to an existing driver.  The
question is, which driver most closely supports these devices?  My simple Google search didn't
turn up much accept that the linux cdc_acm driver seems to support it.  I think this driver is
for serial class USB devices.  Do we have a generic serial clas driver, like we do for class
ethernet USB devices?
Any thoughts on this would be greatly appreciated.
-thanks
