I have a Sierra Wireless 320U USB-to-WWAN modem that does not work with the current sierra and sierra_net drivers included in the Linux kernel. The manufacturer has an updated driver available from their website at http://mycusthelp.net/SIERRAWIRELESS/_cs/AnswerDetail.aspx?aid=44 My modem device works after installing this updated driver. I tested using the current Ubuntu-precise development release with the mainline kernel release 3.3.0-030300rc5-generic from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3-rc5-precise/ The driver versions in linux-3.3-rc5 are: sierra: v.1.7.16 sierra_net: v.2.0 The driver versions for the updated drivers from Sierra Wireless are: sierra: v.1.7.40 sierra_net: v.3.2 The direct link to the updated driver is at http://www.sierrawireless.com/resources/support/drivers/linux/v3.2_1740_kernel-3.0.directIP.tar Tom -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
