Hi,
I've been investigating problem with my Hauppauge WinTV HVR-1400 TV card
(an expresscard) [1], and I've come across warnings produced when I
unload and then reload the cx23885 driver.
Attached is the output from dmesg that shows the card being detected (by
the PCI express hotplug driver)

Well, after lots of hacking diagnostics into cx23885-i2c.c, I'm pretty

Do you have any other express card around to try if it works at all? Try that
always after a cold boot.

Hi, I hope someone can help me.
Firstly, please cc me on any reply because I'm not subscribed.
I have a Hauppauge HVR-1120 card (I thought I was buying an HVR-1100, but 1120
