Problem with USB storage devices, error -110

[Jan-Hendrik Zab]

Hello,
any USB storage devices (like an external USB HDD) that I connect to
the USB PCI adaptor card fail to be 'recognized' correctly by the
kernel. The dmesg output looks like this:

usb 3-1: new full speed USB device using uhci_hcd and address 2
usb usb2: suspend_rh (auto-stop)
usb 3-1: ep0 maxpacket = 8
usb 3-1: khubd timed out on ep0in len=-8/18
usb 3-1: device descriptor read/all, error -110
usb 3-1: new full speed USB device using uhci_hcd and address 3
usb 3-1: khubd timed out on ep0in len=-8/64
usb 3-1: khubd timed out on ep0in len=-8/64
usb 3-1: khubd timed out on ep0in len=-8/64
usb 3-1: device descriptor read/64, error -110
usb 3-1: khubd timed out on ep0in len=-8/64
usb 3-1: khubd timed out on ep0in len=-8/64
usb 3-1: khubd timed out on ep0in len=-8/64
usb 3-1: device descriptor read/64, error -110
usb 3-1: new full speed USB device using uhci_hcd and address 4

I've also uploaded the complete dmesg output to:
http://v3ng34nce.org/dmesg_output.bz2

The computer where the problem appears is running kernel 2.6.18-rc5
now, after showing similar errors under the 'unstable' SMP Debian kernel
2.6.17-1-686.

Greets,

It seems pretty clear that the UHCI controller hardware on your PCI card
isn't working.  The "len=-8/64" messages are a dead giveaway; you can't
get a negative length with a timeout failure if the controller is working
right.  At least, not unless you have some other USB devices already
attached to the same controller and using up all the bandwidth.

The fact that it fails in the same way with all the USB devices you attach 
is another indicator that the controller is bad.

BTW, error 110 is ETIMEDOUT. I have had that on one buggy USB mp3 player 
too - so it's not always the USB host controller.

Thanks for the answers. :)

There is also a HP Deskjet 5652 attached to the card which is
recognized correctly and works just fine, as long as I do not insert
any USB storage device. Of course the printer is just a USB 1.1 device.
So I've tried without the ehci_hcd module loaded and everything seemed
to work as it should. (Well, sorry for not trying this earlier.) So, at
least the UHCI part seems to work as long as there are no EHCI
'functions' involved.
I'll try to get a new adaptor card then.
