Hello,
I have here a HP 6735s laptop to which I've been trying to connect
Tascam's US-122L audio interface. With no luck so far.
Connection goes consistently as follows with 2.6.29-rc4 kernel
patched with Karsten Wiese's modifications to ehci-hcd.
(Same happens with both 64 bit and 32 bit - which I don't
have around anymore, because I went to 64 since I wanted to match the
kernel config to my desktop computer as closely as possible. On
desktop the Tascam works like a charm... Abit/Nvidia mobo, nocona cpu)
...

...
(complete boot log somewhere below)
Using usbmon shows that the interface connects fine most of the times,
but the transfers just freeze almost immediately after the isochronos
transfers begin. After that nothing goes in or out until the interface
is disconnected.
As a sidenote, by Googling, it seems that there has been some problems
with HP laptops and this interface in Win world, too. To address this
a "AMD USB filter driver" has been released. Can't test it though,
since I ditched Vista as soon as I got my hands on this laptop.
I would be all too happy to help debugging this problem further, but -
to be honest - I have no idea how to proceed. Like where to have some
extra debug messages printed and such.
List of information
- kernel version
- lspci
- lspci -v of the ehci controller
- root_hub_lsusb_-vvv
- tascam_us-122l_lsusb_-vvv
And I will have these in separate messages in reply to myself
- halley.config - kernel .config
- boot.log - complete boot log with connection right after boot
