The output from /proc/bus/usb/devices is:
T: Bus=02 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#= 2 Spd=12 MxCh= 0
D: Ver= 1.10 Cls=02(comm.) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1
P: Vendor=0681 ProdID=0034 Rev= 0.00
S: Manufacturer=Siemens AG Wireless Modules
S: Product=MC75
C:* #Ifs= 2 Cfg#= 1 Atr=e0 MxPwr= 0mA
I: If#= 0 Alt= 0 #EPs= 1 Cls=02(comm.) Sub=02 Prot=01 Driver=(none)
E: Ad=81(I) Atr=03(Int.) MxPS= 32 Ivl=128ms
I: If#= 1 Alt= 0 #EPs= 2 Cls=0a(data ) Sub=00 Prot=00 Driver=(none)
E: Ad=83(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=02(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms
However lsusb still only outputs:
bash-2.05# lsusb -v -d 0681:

Note, when I load the ACM driver the modem power shuts down.
