Posted this question here but didn't get any responses, hoping someone can help. Is it something special about the way the SD card is mounted by the USB stick, or a Tomato-related problem?: Has anyone using a 3G modem successfully mounted a micro-SD card that you can put in the modem? I'd like to use it to store bandwidth stats and some binaries. I have Huawei E173 and have put a FAT-formatted 2GB micro-SD card in it. On my laptop it just mounts as mass-storage. On the router's USB support page it is listed as "HUAWEI SD Storage". I have Automount box ticked, but it shows up as unmounted. When I click "Mount" I get a pop-up warning saying "Failed to mount. Verify the device is plugged in, and try again." Any ideas? Am running " Tomato Firmware 1.28.0905 MIPSR2-079V K26 USB Mega-VPN"
