Hi,
we have problems with a Sierra MC7710, it isn't even recognized by the kernel. The device should be included in the current kernel 3.6.11/3.7.2 and I think it is caused by an usb issue. When I take a look at the usb device, I see that there are only 2 subdevices: T: Bus=01 Lev=02 Prnt=02 Port=04 Cnt=03 Dev#= 7 Spd=480 MxCh= 0 D: Ver= 2.00 Cls=ef(misc ) Sub=02 Prot=01 MxPS=64 #Cfgs= 2 P: Vendor=1199 ProdID=68a2 Rev=00.06 S: Manufacturer=Sierra Wireless, Incorporated S: Product=MC7710 C: #Ifs= 2 Cfg#= 2 Atr=e0 MxPwr=0mA /bin/usb-devices: line 79: printf: 0c: invalid number I: If#= 0 Alt= 0 #EPs= 1 Cls=02(commc) Sub=0e Prot=00 Driver=(none) /bin/usb-devices: line 79: printf: 0d: invalid number I: If#= 0 Alt= 0 #EPs= 0 Cls=0a(data ) Sub=00 Prot=02 Driver=(none) But it should look like this (found it in the net): T: Bus=01 Lev=02 Prnt=02 Port=04 Cnt=03 Dev#= 5 Spd=480 MxCh= 0 D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=1199 ProdID=68a2 Rev=00.06 S: Manufacturer=Sierra Wireless, Incorporated S: Product=MC7710 C: #Ifs= 4 Cfg#= 1 Atr=e0 MxPwr=0mA I: If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.)

Sub=ff Prot=ff Driver=(none) /usr/bin/usb-devices: line 79: printf: 08: invalid octal number I: If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=(none) dmesg output: usb 1-1.5: new high-speed USB device number 7 using ehci_hcd usb 1-1.5: config 1 has an invalid interface number: 8 but max is 3 usb 1-1.5: config 1 has no interface number 1 usb 1-1.5: config 2 has an invalid interface number: 12 but max is 1 usb 1-1.5: config 2 has an invalid interface number: 13 but max is 1 usb 1-1.5: config 2 has an invalid interface number: 13 but max is 1 usb 1-1.5: config 2 has no interface number 0 usb 1-1.5: config 2 has no interface number 1 As far as I understand are there 4 subdevices, as it should be normally. 00:14.0 USB controller: Intel Corporation 7 Series/C210 Series Chipset Family USB xHCI Host Controller (rev 04) Maybe someone has seen something like this and knows a solution. best regards Harald
