Subject: [PROBLEM]: onda h600 express card don't work inside the elan u132 usb adapter

I'm trying to use the onda h600 (a pcmcia express card for UMTS-HSDPA)
on an assembled desktop under kubuntu 7.04 (kernel 2.6.22-14-generic),
but the problem is present even in 7.10 and 8.04 alpha 6 (this has a
2.6.24-8-generic kernel). The card apparentely have a ZTE MF330
chipset, and is OHCI compliant.

I want to use it with elan u132, an usb external adapter for
UMTS-HSDPA express cards. In a document found on the net and written
by Tony Olech (the author and maintainer of the elan u132 linux driver
in Elan Digital Systems), I read that the device (u132) must load 2
modules: the ftdi-u132 when it is plugged in the usb port, and the
u132-hcd, when it recognize an express card inside it.

What happen is that, when I insert the card in the u132 device, the
green light (it flashes, is not fix) of the u132 becomes red. On what
I understand, the module ftdi-u132 is loaded but not the u132-hcd.

With an dmesg command I received these data, when I plug the u132 in
the usb port:

N.B.: I deleted many other lines similar to the last above.


The part wiht the failed initialization starts when you enter the onda
h600 in the u132, or starts soon as you have already plugged the onda
h600 in.


I see on ubuntu that there is a bug (129433) that maybe is related:
the user of the onda h600 must place in the blacklist the driver
ehci_hcd, but even if I do that I obtain no good results.

It seems that the second module driver, u132-hcd, have problem when it
try to load itself and u132 so don't recognize the onda h600.

I also include data from scripts/ver_linux:
