Hi, I've a problem with a Sierra Wireless AirCard 881 (PCMCIA) on my ThinkPad X41. It correctly attaches as umsm0, but then only the first port (ucom0) is configured and this port is not "AT-capable". The card has instead four serial ports and the third (ucom2) is the one that accepts AT commands.
Since this card works ok under both winxp and linux, I think I can exclude hardware related problems. This is an extract from dmesg: ohci0 at cardbus0 dev 0 function 0 "NEC USB" rev 0x43: irq 11, version 1.0 usb5 at ohci0: USB revision 1.0 uhub5 at usb5 "NEC OHCI root hub" rev 1.00/1.00 addr 1 ohci1 at cardbus0 dev 0 function 1 "NEC USB" rev 0x43: irq 11, version 1.0 usb6 at ohci1: USB revision 1.0 uhub6 at usb6 "NEC OHCI root hub" rev 1.00/1.00 addr 1 umsm0 at uhub5 port 1 configuration 1 interface 0 "Sierra Wireless, Incorporated AirCard" rev 1.10/0.02 addr 2 ucom0 at umsm0 And output from "usbdevs -dv": Controller /dev/usb0: addr 1: high speed, self powered, config 1, EHCI root hub(0x0000), Intel(0x8086), rev 1.00 port 1 powered port 2 powered port 3 addr 2: high speed, self powered, config 1, External HDD(0x0701), Western Digital(0x1058), rev 2.40, iSerialNumber DEF10C20641E port 4 powered port 5 powered port 6 powered port 7 powered port 8 powered Controller /dev/usb1: addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel(0x8086), rev 1.00 port 1 powered port 2 powered Controller /dev/usb2: addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel(0x8086), rev 1.00 port 1 powered port 2 powered Controller /dev/usb3: addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel(0x8086), rev 1.00 port 1 addr 2: full speed, power 90 mA, config 1, product 0x2441(0x2441), Actiontec Electronics(0x1668), rev 5.46, iSerialNumber \u303 port 2 addr 3: full speed, power 100 mA, config 1, Biometric Coprocessor(0x2016), STMicroelectronics(0x0483), rev 0.01 Controller /dev/usb4: addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel(0x8086), rev 1.00 port 1 powered port 2 powered Controller /dev/usb5: addr 1: full speed, self powered, config 1, OHCI root hub(0x0000), NEC(0x1033), rev 1.00 port 1 addr 2: full speed, power 500 mA, config 1, AirCard(0x6851), Sierra Wireless, Incorporated(0x1199), rev 0.02 Following are informations I've collected using a linux livecd: note that we have four ports recognized as ttyUSB0, ttyUSB1, ttyUSB2 and ttyUSB3, where /dev/ttyUSB2 is the one that can be used for ppp. Can anybody help me? I think we're missing some sort of wake-up/power-on routine for this card in our umsm driver. cheers, David Output from minicom: OK ATI Manufacturer: Sierra Wireless, Inc.
