You can't tell that from the log above. All it indicates is that the ACM driver was loaded. It doesn't say anything about what the driver thinks of the device. > Here is a copy of /proc/usb/devices: > > T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 2 > B: Alloc= 0/900 us ( 0%), #Int= 0, #Iso= 0 > D: Ver= 1.00 Cls=09(hub ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 > P: Vendor=0000 ProdID=0000 Rev= 0.00 > S: Product=USB UHCI-alt Root Hub > S: SerialNumber=8000 > C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr= 0mA > I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub > E: Ad=81(I) Atr=03(Int.)

New devices occur at lines starting with 'T'. The hub driver is bound to the hub device, and nothing is bound to the comm. device. If you turn on USB debugging in your kernel's configuration, you might see some more informative information in the system log.
