After switching off my HP LaserJet 1220 (scan document was fine) I got ton of those errors into dmesg. Problem vanished after switch on printer again. After switch off it was OK again.

Comment 2 David Brownell 2007-10-20 11:36:42 UTC
Can we see "lspci -v" output for the external hub you're using?  Obviously the logic clearing TT faults needs tweaking to handle disconnected devices.  But there are two types of high speed hub, and I think they need different logic there.  Seeing that "lspci -v" info will help sort this out.

I have only one USB2.0 port so it is extended by in-external-lcd-integraded 4 port USB2.0 hub:

Bus 001 Device 008: ID 04b4:6560 Cypress Semiconductor Corp. CY7C65640 USB-2.0 "TetraHub"

Grr, I meant "lsusb -v" not "lspci -v".  But the info I wanted was the "TetraHub" thing, thanks ...

potential fix: don't clear TT faults in some cases

Try this patch.  It just checks for the "disconnected from TT-per-port hub" case and doesn't bother trying to clear that fault ... on the theory that such hubs will clear fault state along with other per-port state on disconnect.

Hi David,

with this patch scanning doesn't even start :(
BTW this device is laser printer combined with scanner (multifunction). To start scanning lp0 is always removed and than during scan phase I see those errors. BTW they are still the same. To support scanning hplip package needs to be installed.

Same errors with patch:

Comment 9 Cijoml Cijomlovic Cijomlov 2007-12-28 02:43:13 UTC
2.6.23.11 still have this problem
Comment 10 Greg Kroah-Hartman 2009-07-28 16:50:03 UTC
Should be fixed in 2.6.30.  If not, please let the developers at linux-usb@vger.kernel.org know about it.
