Hello everybody, [now with the actual attachment] I bought a Sierra GlobeTrotter MC8775 UMTS modem minipci-express with usb interface. I want to use it on my PC engines ALIX.6E2 motherboard (has the latest bios) If I boot the system (it has Debian stable running) and plug in the minipci-express device the modem is detected perfectly and is working. When I do the shutdown -r now command the modem still works after the reboot. Howerver! When I halt the system (shutdown -h now) and pull out the powercable from the motherboard, and plug in back in to boot the system. The minipci-express usb device is unable to enumerate! Rebooting or unloading modules does not help. Other usb device seem to stay working. I plugged the minipci-express usb device in an intel mini-itx system to test it and there the device works fine after powerdown and replugging the cables. I tried 2.6.26+17+lenny1, 2.6.30+21 and 2.6.32+23 kernels all do the same. Does somebody know what is going on? Any help would be really appreciated? Thanks in advance, Kind regards, Jelle
