So usbserial isn't the right driver for it. Also, it runs at low speed (1.5 Mb/s) and doesn't have any way to send data to the computer -- the listing below shows that it is output only. > root@dm800:~# cat /proc/bus/usb/devices > T: Bus=02 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#= 3 Spd=1.5 MxCh= 0 > D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 > P: Vendor=0e6a ProdID=0101 Rev= 5.10 > S: Product=USB Bridge > C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=100mA > I: If#= 0 Alt= 0 #EPs= 1 Cls=ff(vend.)

It uses a vendor-specific communications protocol, so Linux might not have any drivers for it.
