I have bought a wireless modem to use with my eee 900, namely a sony ericson MD300.
At first, it is recognized by debian kernel 2.6.26 as a storage device. Following information gathered on the web, I created a rule file under /etc/udev/rules.d/ with the following content: ACTION!="add", GOTO="3G_End" BUS=="usb", SYSFS{idProduct}=="d0cf", SYSFS{idVendor}=="0fce", NAME="%k", SYMLINK="modem3G-%n", PROGRAM="/bin/sh -c 'echo 3 > /sys/%p/device/bConfigurationValue'" LABEL="3G_End" The 'echo 3' command seems to make the black magic, and the card is recognized as an ACM device, and now it is working fine as a modem. However, the usb device has several interfaces and endpoints: [EMAIL PROTECTED]:~$ cat /sys/class/usb_device/usbdev2.1/device/2-1/2-1\:3.*/interface S_WHCM Sony Ericsson MD300 Mobile Broadband WMC ETH Bulk Data Sony Ericsson MD300 Mobile Broadband Modem Sony Ericsson MD300 Mobile Broadband Modem bulk data Sony Ericsson MD300 Mobile Broadband Modem Sony Ericsson MD300 Mobile Broadband Modem bulk data Sony Ericsson MD300 Mobile Broadband Device Management (WDM) Sony Ericsson MD300 Mobile Broadband Device Management (WDM) Sony Ericsson MD300 Mobile Broadband Device Management (WDM) Sony Ericsson MD300 Mobile Broadband Device Management (WDM) Sony Ericsson MD300 Mobile Broadband WMC ETH Comm interface and those give a bunch of kernel errors: Oct 29 11:30:00 kalma kernel: [ 8030.092104] usb 2-1: new full speed USB device using uhci_hcd and address 3 Oct 29 11:30:00 kalma kernel: [ 8030.328028] usb 2-1: configuration #1 chosen from 3 choices Oct 29 11:30:00 kalma kernel: [ 8030.337412] scsi1 : SCSI emulation for USB Mass Storage devices Oct 29 11:30:00 kalma kernel: [ 8030.338103] usb-storage: device found at 3 Oct 29 11:30:00 kalma kernel: [ 8030.338112] usb-storage: waiting for device to settle before scanning Oct 29 11:30:00 kalma kernel: [ 8030.340349] usb 2-1: New USB device found, idVendor=0fce, idProduct=d0cf Oct 29 11:30:00 kalma kernel: [ 8030.340361] usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Oct 29 11:30:00 kalma kernel: [ 8030.340368] usb 2-1: Product: Sony Ericsson MD300 Oct 29 11:30:00 kalma kernel: [ 8030.340373] usb 2-1: Manufacturer: Sony Ericsson Oct 29 11:30:00 kalma kernel: [ 8030.340378] usb 2-1: SerialNumber: 3534460246464300 Oct 29 11:30:01 kalma kernel: [ 8030.499239] cdc_acm 2-1:3.1: ttyACM0: USB ACM device Oct 29 11:30:01 kalma kernel: [ 8030.505297] cdc_acm 2-1:3.3: ttyACM1: USB ACM device Oct 29 11:30:01 kalma kernel: [ 8030.519117] kobject_add_internal failed for usbdev2.3_ep85 with -EEXIST, don't try to register things with the same name in the same directory.

Can someone point me to the right direction to understand these errors and complete the configuration of this card? Although it is working, I would like to correctly configure the other card endpoints (besides the modem) to access its features, such as usb ethernet device and gsm information (signal strength and connection type).
