enumeration issues with minipci-express usb device after power-cycle

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello everybody,

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
