Subject: ehci: disable the Philips ISP1561 usb hub
From: Bruno Redondi <[EMAIL PROTECTED]>
Taken from http://bugzilla.kernel.org/show_bug.cgi?id=9562
I am trying to use a PCMCIA PC-CARD GPRS/UMTS/HSDPA MODEM PC-CARD is branded
as ONDA H600 and is extremely popular in Italy since it is the "default" UMTS
PC-CARD by a provider in the country. PC-CARD is actually a re-branded ZTE
MF330 so it should be quite popular in other countries as well. Apparently,
also the older ONDA NH501HS is again a ZTE MF330, so the following should
apply also to that card.
When the card is inserted into the PCMCIA slot, the following should happen:
- kernel should recognize an OHCI Host Controller
- kernel should recognize an ONDA CDMA Technologies MSM (Manufacturer:
Qualcomm, Incorporated) attached to it
- kernel should configure 3 ttyUSB devices provided by the 3 serial
interfaces of the ONDA MSM
Unfortunately, with the linux kernel this does not happen Rather, the kernel
gets confused, detects an EHCI Controller, loads the kernel module for it and
no serial interfaces appear.
As an hack, the correct behaviour can be obtained by blacklisting the ehci_hcd
for instance in /etc/modprobe.d/blacklist-modem. When the ehci_hcd is
blacklisted everything works correctly and the ONDA Wireless UMTS PC-CARD gets
perfectly usable.
lspci reports the datacard as a Philips ISP1561 EHCI USB 2.0 (1131:1562), so I
excluded this device from ehci-pci and i can use the datacard without
blacklisting the module.
