What dmsg appears when you attach your device? If "ugen", then make sure you 
have got "device ucom" and "device uplcom", in the kernel config file. If you 
are loading "ucom"/"uplcom" from modules, make sure that those modules are 
re-compiled. Else try to enable debugging and see what happens:

sysctl hw.usb.uplcom.debug=15
sysctl hw.usb.ucom.debug=15

and

sysctl hw.usb.debug=15
