This may not answer your question, but I have several 2960 Cisco
switches and the USB port on them works just fine with umodem.  In the
2960, they identify as:

[ 609123.259177] umodem0 at uhub1 port 5 configuration 1 interface 0
[ 609123.259177] umodem0: Cisco (0x5a6) Cisco USB Console (0x09), rev 
2.00/0.00, addr 6, iclass 2/2
[ 609123.259177] umodem0: data interface 1, has no CM over data, has no break
[ 609123.259177] umodem0: status change notification available
[ 609123.259177] ucom1 at umodem0
[ 609163.321067] ucom1: detached
[ 609163.321067] umodem0: detached
[ 609163.321067] umodem0: at uhub1 port 5 (addr 6) disconnected

Seems like that may be what you have.

Hello.  Thank you very much.  Indeed the umodem(4) recognized the 
device, but I missed the
dmesg output.  
thanks for the tip.

The umodem(4) driver is for the USB CDC class and should understand it.



Cisco USB serial console compatiblity?

2021-06-02 Thread Brian Buhrow
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
