Bug#615609: [loongson-dev] Bug#615609: linux-image-2.6.37-1-loongson-2: Lemote mini-pc with linux-image-2.6.37-1-loongson-2 doesn't support external usb NIC (TU2-ET100)

Done, it works well on x86_32 and x86_64 (both intel).

I've also tried:

acpi=noirq
usbcore.autosuspend=-1

Which in the past have been able to solve other serial usb issues, but
none worked out...

I'll look for them.  I acquired another one to try, but at the end it
was based upon the same chipset, so also the same driver, so it didn't
help.  I'll look in the web...

Thanks a lot Roman, I'll investigate as soon as possible.  I'd like a
work around before going to buy something else, so this will be my
first step, :-)

So far no luck, but I'll keep trying, and if anyone gets to find
something, please let me know...

Javier.
