[2.6.8 ->] Problems, hci_usb dosn't work.

Hi,

Since some kernel version i can't exactly remember which, i have been unable to use usb, i have tested with with 2.6.8 -> 2.6.9-rc2-bk7 and i also applied your patches for 2.6.8.

I have 2 usb dongles, one old that did work once, and one new that seems to be working like the older but it doesn't work with linux.

Both are based on the CSR chipset, here is the new ones entry from the hw support list:
MSI MS-6967 CSR 1.1 hci_usb working Dave Beckett

Som logs from insertions:
usb 1-3.4: new full speed USB device using address 12 ehci_hcd 0000:00:02.2: qh f7e54780 (#0) state 1

hci_usb_intr_rx_submit: hci1 intr rx submit failed urb d315eef4 err -28

both of these are connected to usb 2.0 hubs (this machine does usb 2.0)

Output from hciconfig:

0) = 0xb7fe8000
write(1, "Can\'t init device hci0. Input/ou"..., 46Can't init device hci0. Input/output error(5)
) = 46

Basically, it just stopped working and i dunno why, any clues? at all?

Hi Ian,

this looks like an USB problem to me. Try to connect it to USB 1.1 ports and see if this works.

The problem is, this computer doesn't have a usb 1.1 port. But it should basically fallback, and afair it worked with a cable direct to the computer, i haven't tested that since... because i need the hubs.

But if it indeed is a usb 1.1 vs 2.0 problem then it has to be something broken in the kernel... Anyone else using this with usb 2.0?

Ian Kumlien <pomac () vapor ! com> -- http://pomac.netswarm.net

Hi Ian,

this problem was reported two or three times, but I am unable to reproduce it with my USB 2.0 host controllers.

Regards

Marcel

What controller do you use? and what usb1.1 driver?

Ian Kumlien <pomac () vapor ! com> -- http://pomac.netswarm.net

Hi Ian,

your IRQ looks very weird. I have never seen an IO-APIC system assigning IRQ 185 to any device. Does any other USB device works in conjunction with this controller?

I use a NEC controller with an OHCI for USB 1.1 stuff.

2 joysticks, one 6in1 card reader and one muvodrive, it all works. And, it registers the device correctly it just can't read from it.

And yeah i know, it's part of the nvidia workaround:

hurrm ohci_hcd should have data... hurrrm, it might be LKML related after all.. =P
(I might have left the experimental 'ohci' support in ehci on in this kernel.)

Heh ok

Ian Kumlien <pomac () vapor ! com> -- http://pomac.netswarm.net

Hi Ian,

are these devices all USB 2.0 capable? If yes, then they are handled by the ehci_hcd host controller driver.

Check that first and then report it to the Linux USB mailing list. It is more an USB issue then LKML related.

Regards

Marcel

All except the monitor that also registers it self via usb, =) (I am really surprised about that actually)

And here is the usb dongle output
hci_usb

Should i change some identifier and test some?

yep... Assumed, i just assumed that some small thing might be broken and that you usb ppl would be quicker to spot it =)

Ian Kumlien <pomac () vapor ! com> -- http://pomac.netswarm.net

Hi Ian,

here is nothing really important missing, because 0xe0 means wireless class or so.

This looks really like an ohci_hcd problem with interrupt URBs.

Marcel

The reply i received:
Error -28 is -ENOSPC, which means the USB bandwidth was exhausted. Too many devices were plugged into the same controller. Unplugging some of the other devices ought to help. Or even plugging the BT controller into one of the other ports rather than the external high-speed hub, since it is only a full-speed device.

Then i moved the usb dongle around in the newly discovered 2 usb ports...and suddenly it worked (only in one of the two usb ports though) and now i'm not touching it! =)

Thanks for all the help =)
